||With significant declines in home prices since 2007, many U.S. households have found the balance of their mortgage exceeding the value of their property. These underwater homes leave owners with the dilemma of continuing to pay on their note or relinquishing their property either through foreclosure or a short sale. A number of studies have looked at discounts on foreclosed property. Discounts range from a low of 4 to 6 percent in Springer (1996) to a high of 24 percent in Shilling, et al (1990). More recently, Claretie and Daneshvary (2011) examine three forms of distressed sales in Las Vegas and estimate that, in 2008, the average discount from an arm’s-length transaction was 5.6 percent for a short sale, 10.3 percent for a home in default and 13.5 percent for an REO. Whereas Claretie and Daneshvary use multiple listing service (MLS) data, our study analyzes tax records from the Las Vegas metropolitan area over the period 2007 through the second quarter of 2011. By using tax record data and extending the period of analysis, we are able to investigate housing prices in a downward spiraling market. While the county utilizes a multi-category coding system to identify various types of property sales, three primary transactions are of interest in this analysis: a) an “R” transaction, where the price reflects an arms-length sale between a willing buyer and seller, b) a “T” designation refers to a price bid on the property at foreclosure during a trustee sale and c) , an “F” transaction denotes the selling price of a property after foreclosure. For a given property, historical sequencing of transaction type designations allows us to infer the circumstances of the most recent sale. As home prices continue to fall and more homeowners find themselves underwater, distressed sales will make up a larger proportion of sales. Nevertheless, many of these transactions in the form of either a short sale or a home in default may be recorded by the county as an arm’s-length (R) transaction thereby changing its meaning over time. This has important implications for house price indexes and tax assessments as both utilize arm’s-length transaction prices. Given that arm’s length transactions could include distressed sales, the analysis will apply a form of propensity score matching to adjust the circumstances of the final sale. In this manner, it will be possible to measure the “pure effect” of foreclosure and how this changes over time.
