Abstract
Commercial real estate investors are likely exposed to a large amount of idiosyncratic risk, because individual properties often constitute a non-trivial share of their portfolios. The idiosyncratic risk is characterized with deviation of investment returns of individual properties from average market returns, which is a cross-sectional instead of a time series measurement and differs from the temporal variation in index returns that the existing literature traditionally focuses on. Using detailed cash flow information of 3,240 commercial properties that were held between 1977 and 2009 by institutional investors in the NCREIF database, this paper measures the property level idiosyncratic risk and finds strong evidence that it increases with the length of the investment holding period, and decreases with the average real estate investment returns in the local market but not the national market. There is also some evidence that the risk is lower if properties are acquired in periods when market valuation is low (higher cap rates) and are sold in periods when market liquidity is high.

I. Introduction
Direct commercial real estate investments constitute a large portion of the total wealth in the
United States, with the estimated value being about $2 trillion.1 Commercial real estate investors
are likely exposed to a large amount of idiosyncratic risk, because individual properties often
constitute a non-trivial share of their portfolios. However, the existing literature on the risk of
commercial real estate investments traditionally focuses on large real estate funds or indices (see,
e.g. Geltner (1989); Geltner and Goetzmann (2000), Goetzmann and Ibbotson (1990), Ling and
Naranjo (1997), Pai and Geltner (2007); Plazzi, Torous and Valkanov (2008), Peyton (2009),
among others), and measures investment risk with temporal variation in index or fund returns.
However, the idiosyncratic risk that investors are exposed to is characterized with deviation of
individual asset returns from average returns of similar properties, which is a cross-sectional
instead of a time series measurement (see, e.g. Fisher and Goetzmann (2005) for evidence of
significant differences between the two different risk measurements). Therefore, while the index-
based or fund-based research makes important contributions to the literature, the literature
provides little empirical evidence or theoretical insights regarding the determinants and asset
pricing implications of the idiosyncratic risk of commercial real estate investments.
This paper aims to conduct some very basic but fundamentally important empirical analyses
regarding the determinants of the idiosyncratic risk. In this paper, the idiosyncratic risk of a
property investment is defined as the volatility of the component of the gross total return of the
property over its holding period that is not explained by the average gross total return over the
same period of an index that track similar (the same property type) properties in the same location
(Core Based Statistical Area, or CBSA, specifically in this paper), which we call the risk
Measurement 1, or similar properties in the entire economy, which we call the risk Measurement
2. This paper analyzes the relationship between the two risk measurements with three sets of 1 2005 value, data source is Make Room for Real Estate, New York, Freeman and Company, LLC.

variables: the length of the holding period and the local (CBSA) or national market performance
during the holding period, the average market valuation of properties (measured with median
market transaction cap rate) when the property is acquired and disposed, and the market liquidity
(turnover) when the property is acquired and disposed. The selection of these variables is indeed
relatively ad hoc, which is due to the lack of theoretical insights regarding the determinants of the
idiosyncratic risk. Nonetheless, the empirical analyses in this paper have the potential to help
establish stylized facts and stimulate future research. We hope this paper would generate more
interest and more future work that help economists and investors improve the understanding of
the large amount of idiosyncratic risk commercial real estate investors take.
We construct both risk measurements and the three sets of explanatory variables using the
National Council of Real Estate Investment Fiduciaries (NCREIF) database, which seems the
most comprehensive and accurate database that provides detailed operational and financing
information of large “institutional-quality” commercial real estate in the U.S. since 1977. We
find very strong evidence that the idiosyncratic risk increases with the length of the holding
period, and is reduced by the performance of the CBSA index but not the performance of the U.S.
market index. We find weak evidence that the risk is lower if properties are acquired when
market valuation is low (cap rate is high), and disposed when market liquidity is high. This paper
is the first, to our knowledge, that analyzes the determinants of the idiosyncratic risk of
commercial real estate investments.
The rest of this paper is organized as follows. Section II discusses the measurements of the
idiosyncratic risk and the empirical model. Section III discusses the data set and the construction
of explanatory variables. Section IV presents the empirical results. Our conclusions are presented
in the last section.

II. Definitions and Models
The main measurement in this paper of the idiosyncratic risk of a property investment over its
holding period, which we call Measurement 1, is the volatility of the component of the gross total
return of the property over its holding period that is not explained by the average gross total
return of an index that track similar properties in the same location over the same period. While
properties can be similar in many ways, the type of the property – being apartment, industrial,
office, and retail – has been documented as an important determinant of real estate investment
risk and returns (see, e.g. Peng (2010), among others). Therefore, this paper considers the same
type of properties as “similar” properties.
There is a tradeoff in the definition of location. The smaller is the size of the location, the more
homogeneous are the risk and return characteristics of properties in the same location. However,
the smaller size also leads to fewer similar properties in the same location, which makes it more
difficult to measure the average investment performance of similar properties. This paper treats
each CBSA as a distinct “location”. There are roughly 40 CBSAs in our dataset where roughly
80% of the properties in the sample are located. Therefore, there are sufficient property
observations to estimate indices for these CBSAs. Further, note that it is plausible that “similar”
properties in the same CBSA are subject to similar market conditions, and thus have relatively
homogeneous investment performance.
This paper also analyzes an alternative measurement of the idiosyncratic risk, which we call
Measurement 2. Measurement 2 is the component of the gross total return of the property that is
not explained by the gross total return of an index that track similar properties in the U.S. market
over the same period. This index is estimated from the sample used in this paper. It is apparent
that the main difference between Measurements 1 and 2 is that Measurement 2 treats systematic
deviation of CBSA property returns from national average also as idiosyncratic risk, while
4
Measurement 1 does not. This paper uses the alternative measurement to investigate to what
extent the use of CBSA index instead of the national index as the benchmark group affects the
results, and whether our results are robust to the choice of the benchmark groups.
Below we first provide precise definition for the gross total return of a property over its holding
period, and then presents the econometric model we use to calculate the two measurements of the
idiosyncratic risk. Note that the gross total return of investing in a commercial property is
determined by not only the value appreciation over the holding period, but also cash flows during
the period, including the net sale proceeds from a possible partial sale of the property (Partial),
the Net Operating Income (NOI), and the Capital Expenditure (Capex). Since this paper uses a
discrete time model, it assumes that NOI is received, Capex is spent, and the possible partial sale
takes place at the end of each quarter.
We define the gross total return of property i from period t to t +1 , Ri,t+1 , as
Ri,t+1 =
NOIi,t+1 −Capexi,t+1 + Partiali,t+1 +Valuei,t+1
Valuei,t
, (1)
where Valuei,t+1 is the net sale proceeds the owner would have received if she had sold the
property at the end of period t +1 , with the only exception being that it equals the acquisition
price in the acquisition quarter. The gross total return from the acquisition period, tbuyi , to the
disposition period, tselli , is defined as
Ri = Ri,tt=tbuy
i +1
tselli
∏ . (2)
While the gross total return for each interim period is unknown due to the lack of transactions and
thus the lack of market value observations before the final disposition, the gross total return over
5
the entire holding period equals the internal rate of return (IRR) with the power raised to the
length of the holding period. Since all cash flows over the holding period, including the
acquisition cost, NOI, Capex, Partial, and the net sale proceeds, are known, we can calculate the
IRR from the cash flows, and then calculate the gross total return. Note that when calculating the
IRRs, there are sometimes multiple solutions. To select the most sensible IRR for each property,
we first calculate the geometric average value appreciation per period using the acquisition cost
and the final net sale proceeds only, and use it as a benchmark. While this benchmark does not
take into account interim cash flows, it captures the value appreciation component of the total
return, and thus provides a good guide regarding the sign of the actual IRR. After calculating this
benchmark for each property, we obtain all the IRR solutions for the property, and then select the
number that is closest to the benchmark as the actual IRR.
After defining gross total returns for property investments, below we present the calculation of
the idiosyncratic risk, which is achieved with the Generalized Repeat Sales Regression (GRSR)
proposed by Peng (2011). The GRSR allows the estimation of price indices for submarkets,
which are CBSAs in this paper, that have small numbers of repeat sale observations. The key
assumption that enables this estimation is that properties in each submarket are relatively
homogeneous, and the difference in price appreciation between each submarket and the overall
market can be captured with “sensitivity” parameters. Peng (2011) proposes to use the EM
algorithm to estimate the GRSR.
Specifically, assume that the log of the gross total return of property i from period t to t +1 ,
Ri,t+1 , has a national market component (the market index MarketIndext+1 ) and a local
component (local sensitivity τCBSAi for the CBSA where property i is located).
log Ri,t+1( ) = τCBSAiMarketIndext+1 + ε i,t+1 (3)
6
The product of the local sensitivity and the market index is the CBSA index. Two things are
worth noting in (3). First, the only difference between the GRSR model in (3) and the
conventional RSR is that the conventional RSR forces τCBSAi to be 1. Second, it is possible to let
τCBSAi be a function of variables such as market conditions, but this paper maintains the simplest
assumption and focuses on the determinants of the idiosyncratic risk.
The gross total return (in log) of the property over the holding period can be written as
log Ri( ) = log Ri,t( )t=tbuyi +1

We further simply the notation and denote the error term as

Measurement 1 of the idiosyncratic risk equals the squared regression residual ei2 .
This paper uses the two-step EM algorithm proposed by Peng (2011) to estimate (4). The first
step pools properties in all CBSAs, holds constant τCBSAi for each CBSA, which was estimated
from the previous iteration, and estimates (4) to obtain the MarketIndext{ }t=1T
. The initial value
of τCBSAi is set to be 1 for all CBSAs. The second step estimates (4) for each CBSA separately.
In each CBSA level regression, the national index MarketIndext{ }t=1T
obtained from step one is
treated as known, and (4) is estimated to obtain τCBSAi for the CBSA. The two steps are iterated
until both MarketIndext{ }t=1T
and τCBSAi for all MSAs converge.
7
Two issues in the estimation are worth discussions. First, some CBSAs have small numbers of
observations of property investments, so the estimated τCBSAi is not reliable due to the small
degree of freedom in the second step of the iteration. To overcome this problem, while we keep
property investments in these CBSAs to improve the estimation of the national market index, we
let τCBSAi remain 1 for CBSAs with fewer than 10 property observations, and do not update the
value of τCBSAi for such MSAs in the iteration.2 In our analyses of the determinants of the
idiosyncratic risk, we exclude these CBSAs and focus on others that have more reliable
estimation of τCBSAi . Since there are only roughly 20% of observations that are located in these
CBSAs with small numbers of observations, the results are robust when all property investment
observations are included.
Second, multicollinearity sometimes presents in the first step regression of the iteration. As a
result, some consecutive quarters cannot be distinguished from each other. That is, while the
regression provides an estimate for the aggregate index value (sum of periodic index values) over
these consecutive periods, the index value for each period cannot be determined. However, it is
important to note that this does not affect the construction of the idiosyncratic risk. Equations (4)
indicates that, when constructing the factors for each property, it is the aggregate index value (the
sum of periodic index values) over the holding period that matters. The very reason why some
consecutive periods cannot be distinguished from each other is that they are all interim periods
between acquisition and disposition for all properties.
We construct Measurement 2 of the idiosyncratic risk from a restricted version of (4).
Specifically, we force τCBSAi to be 1 for all CBSAs in (4), estimate this restricted model, which is

This paper focuses on three types of variables. The first type pertains to the holding period, and
consists of the length of the holding period and the gross total return of the CBSA index (or the
market index for Measurements 2) over the holding period. The third type is related to the
average valuation of properties in the market, which are the median market transaction cap rates
in the acquisition and the disposition periods respectively. The third type captures the market
liquidity, and consists of two variables that measure the market liquidity in the acquisition and the
disposition periods respectively.
III. Data
This paper constructs the idiosyncratic measurements and the explanatory variables using the
National Council of Real Estate Investment Fiduciaries (NCREIF) database. The NCREIF is a
not-for-profit institutional real estate industry association established in 1982. It serves the real
estate investment industry by collecting, processing, validating and then disseminating
information on financing and operation of commercial real estate. The NCREIF database
comprises institutional-quality commercial properties owned or managed by NCREIF investment
managers and plan sponsors in a fiduciary setting.
9
The NCREIF database used in this paper contains information on physical attributes, cash flows,
and transactions of 23,771 properties over the 1977:1 to 2009:3 period. The physical attributes of
each property include the property type (e.g. apartment, office, industrial, retail, and hospitality
properties, etc.), year built, gross square feet, street address, and the CBSA where the property is
located, etc. The cash flow and transaction information includes quarterly net operating income
(NOI), capital expenditure (Capex), as well as the acquisition cost or the net sale proceeds if
applicable. All cash flow and transaction information is on an unlevered basis.
This paper focuses on the four main property types - apartment, industrial, office, and retail
properties – which comprise 22,313 properties in the database. For each property type, we
estimate the quarterly time series of the median transaction cap rate and market liquidity over the
1977:1 and 2009:3 period. In estimating the median transaction cap rate in a quarter, we first
calculate the cap rate for each property acquired or disposed in this quarter. Specifically, we
calculate the cap rate for each property acquisition (disposition) by dividing the median of the
quarterly NOI in the four quarters after the acquisition quarter (before the disposition quarter)
with the acquisition cost (gross sale proceeds), and then annualizing the cap rate (multiplying it
with 4). We use the median NOI to mitigate the effect of errors in NOI on the cap rate
calculation. We then calculate and record the median of all transaction cap rates in each quarter if
there are at least 5 cap rate observations. Figure 1 plots the median transaction cap rate for each
of the four property types over the 1977:1 to 2009:3 period.
For each property type, we also estimate the market liquidity in each quarter, which is measured
with the fraction of NCREIF properties traded (acquired or disposed) in that quarter. We use the
information on acquisition and disposition periods to calculate the number of properties held by
NCREIF members in each quarter, and then divide the number of transactions (both acquisitions
and dispositions) in that quarter with the number of all properties. It is apparent that this
10
measurement is more accurate in later sample periods when the NCREIF database comprises
more properties. However, the empirical results presented later are robust when only the second
half of the sample period is used for the analyses.3 Figure 2 plots the market liquidity for each of
the four property types over the sample period.
To construct the dependent variable in our analyses, we calculate the idiosyncratic risk for 3,240
properties that have complete and seemingly accurate cash flow and location information. The
3,240 properties are selected from the 22,313 properties using the following rules. First, note that
most of the properties (about 67%, or 15,000) have not been disposed by 2009:3. Therefore, the
investment performance of these properties is not observed. Further note that a few properties
that have been disposed have missing information on the acquisition period/cost and disposition
period/net sale proceeds. After excluding these two kinds of properties, the sample size is 7,242.
Second, we further clean the 7,242 properties. Specifically, we exclude properties that are the top
1% and the bottom 1% of the distribution of quarterly value appreciation IRR over the holding
period (to mitigate errors in acquisition cost or net sale proceeds), the top 1% and the bottom 1%
of the distribution of the ratio of average quarterly NOI to acquisition cost (to mitigate errors in
NOI), the top 1% of the distribution of the ratio of the average quarterly Capex to acquisition cost
(to mitigate errors in Capex). We also exclude properties of which the maximum quarterly Capex
is more than 50% of the acquisition cost (to mitigate errors in Capex), and properties that have
identical NOI or Capex for more than 10 consecutive quarters. After applying these rules, the
sample size becomes 3509. We then calculate the total return IRR for each property, and exclude
133 properties with missing IRR due to the limit of the R function that calculates IRR that it does
not work for holding periods longer than 48 periods. Finally, we exclude properties that are the
top 2% and the bottom 2% of the total return IRR distribution, to mitigate errors in the IRR

calculation due to the presence of multiple solutions. This leads to the final sample of 3,240
properties.
Table 1 summarizes the 3,240 properties in the final sample, which comprise 911 apartment, 898
industrial, 1,012 office, and 419 retail properties. It is apparent that these properties are
“institutional” real estate – they tend to have large size and high values. For the four property
types, the average purchase price is about $24 million, $15 million, $37 million, and $25 million
respectively. The average net sale proceeds is about $30 million, $18 million, $46 million, and
$30 million respectively. The average annual total return IRR is respectively 8.26%, 6.61%,
7.43%, and 10.10%, but the IRRs have large standard deviations. To visualize the distribution of
the property IRRs, Figure 3 plots the histogram of the quarterly property gross total return IRR
over the holding periods for all 3,240 properties. Table 1 also shows that the average holding
period is 18 quarters for apartment, office, and retail properties, and 15 quarters for industrial
properties.
Table 2 reports the mean and the standard deviation of the two Measurements of the property
idiosyncratic risk for the four property types. A few things are worth noting. First, Measurement
1 is smaller than Measurement 2, which is not surprising since both the national market index and
the CBSA common component is excluded when calculating the risk measurement 1. Second,
there is large variation in both measurements – the standard deviation for each property type and
each measurement is roughly twice as large as the mean. Third, the magnitude of the risk seems
to vary across the four property types. Particularly, office properties have the largest average
idiosyncratic risk regardless the measurement used.
Table 3 reports the across-time mean and the standard deviation of the median transaction cap
rate and the liquidity (NCREIF turnover) in the market for each of the four property types. Note
12
that the statistics of the cap rate are not comparable across property types since each type has
missing information for different time periods. The liquidity/turnover measure is more
comparable than the cap rate, as there are much fewer periods with missing information. This
table shows that industrial properties have the lowest average liquidity/turnover among the four
property types, and apartment properties have the highest average liquidity/turnover.
IV. Results
The empirical regressions of the risk idiosyncratic risk use properties located in CBSAs for which
CBSA indices are estimated, so the sample size is slightly smaller than 3,240. Table 4 reports the
regressions of idiosyncratic risk on holding-period related variables. Panel A reports regressions
of Measure 1 of the idiosyncratic risk of each property on an intercept term, the length of the
holding period, and the gross total return over the same period of the CBSA index constructed
using the GRSR in (4). All four types of properties have consistent and strong results. First, the
idiosyncratic risk is positively related to the length of the holding period. The coefficient ranges
from 0.002 for apartment to 0.04 for the other three types of properties, and are statistically
significant at the 5% for apartment and at the 1% for others. This result indicates that commercial
properties are similar with residential properties in the sense that the idiosyncratic risk increases
with the holding period (see, e.g. Case and Shiller (1987), Goetzmann (1992), among others, for
evidence of the positive relationship between the idiosyncratic risk and the length of holding
period).
Second, there is strong and consistent evidence that a better performance of similar properties in
the CBSA helps reduce the risk. The coefficient of the CBSA total return index over the holding
period is -0.097 (significant at the 5%) for apartment, -0.037 (significant at the 5% level) for
industrial, -0.049 (significant at the 10%) for office, and -0.09 (significant at the 5% level) for
retail properties. This finding is documented for the first time in the literature, and seems to
13
suggest that when commercial real estate investors experience greater returns, they are also
exposed to lower idiosyncratic risk. We hope future theoretical work can help understand this
novel finding and its implications on investment.
Panel B reports regressions of Measurement 2 on the length of the holding period and the gross
total return of the U.S. index over the holding period. The length of holding period is still
statistically significant in increasing the property idiosyncratic risk for all four types of properties.
However, the return of the U.S. index is no longer significant, except for apartment properties
(coefficient being -0.121 and significant at the 5% level). This difference between Panels A and
B seems to indicate that the risk-reduction effect of market performance is at the regional level. It
is the performance of the local real estate market - not the national market - that affects the
idiosyncratic risk of commercial property investments. This finding also highlights the important
asset pricing implications of the location-heterogeneity of the commercial real estate market.
Table 5 reports regressions of both measurements on the median market transaction cap rates in
the acquisition and disposition periods. Panel A shows weak evidence for a negative relationship
between the cap rate in the acquisition period and the idiosyncratic risk. Properties acquired
when the median market cap rate is higher, which means properties are “cheaper”, tend to have
lower idiosyncratic risk. However, note that while the coefficient is negative for all four types of
properties, it is only significant for apartment (at the 1% level) and retail (at the 10% level)
properties. Panel B provides some but even weaker evidence for the relationship between the
median cap rate in the acquisition period and the idiosyncratic risk. The coefficient is significant
(at the 5% level) only for apartment properties. Both Panels do not provide any evidence for the
relationship between the market cap rate at the disposition period and the risk.
14
Table 6 reports the regressions of both risk measurements on market liquidity at the acquisition
and disposition periods. There is no evidence for any relationships between the market liquidity
at acquisition and the magnitude of the idiosyncratic risk; however, there is some evidence that
market liquidity at disposition helps reduces the risk. Specifically, Panel A reports negative
coefficients of market liquidity at disposition for apartment and retail properties, significant at the
5% and the 1% level respectively. Similar but weaker evidence can be found in B. The
coefficient is significantly negative (at the 5% level) for apartment properties only. Overall, it
seems that selling properties when the market is liquid can reduce the idiosyncratic risk for
apartment and retail but not the other two types of properties.
We have also conducted some robustness checks by replicating Tables 4 to 6 using properties
acquired in the later half of the sample period. This is to see if the results we find are driven by
the less accurate measurements of the explanatory variables, such as the market cap rate and
liquidity, in earlier periods. The sub-sample analyses provide consistent results with Tables 4 to
6, which are not reported but available upon request.
V. Conclusion
This paper is the first that estimates the idiosyncratic risk of commercial property investment, and
empirically analyzes its relationship with a variety of real estate market conditions. The results
indicate that the idiosyncratic risk increases with the length of holding period, decreases with the
market performance in the local market, but not the national market, during the holding period.
Further, for apartment and retail properties, the risk is reduced if properties are acquired when
market valuation is low and sold when the market is liquid. We hope this paper can generate
more interest in the research area about the determinants and the implications of the idiosyncratic
risk of commercial real estate investments, which is important given the large size of the
commercial real estate market and the significant impact of its performance on the economy.

Measurement 1 for a property is the squared difference between the total return (in log) of the property during its holding period and the total return (in log) of an index of properties of the same type in the same CBSA during the same period. Measurement 2 is the squared difference between the total return (in log) of the property during its hold period and the total return (in log) of a national index of properties of the same type during the same period.
