The U.S. Census Bureau and U.S. Department of Housing and Urban Development’s Rental Housing Finance Survey provides property-level information on characteristics such as size of property, type of mortgage, ownership type, interest rate, and current market value for units in buildings with 2 or more units in them. National summary tables are available, as well as more detailed microdata.
Multifamily Mortgage Lending
National quarterly estimates of multifamily mortgage credit outstanding, and net quarterly change, by lender group, are available from the Federal Reserve. Data can be accessed by selecting Mortgage Debt Outstanding.
Detailed loan-level data on FHA-insured multifamily mortgages is available on the FHA's web site.
HUD also formerly maintained a multifamily GSE database that includes information on number, type and affordability of units and the size of the property, mortgage balance, and type of organization that sold the mortgage to the GSE. Data are available until 2007.
Freddie Mac and Fannie Mae also provide loan performance data. Freddie Mac’s “Multifamily Loan Performance Dataset” can be accessed here (available on the right-hand column), and Fannie Mae’s Multifamily Securities Locator Service provides multiple datasets.
Low Income Housing Tax Credits
Information on the low income housing tax credit program comes from several government and trade association sources. An evaluation of the program was completed in 1997 by the U.S. Government Accountability Office. The National Council of State Housing Agencies also produces estimates of the number of new properties. Detailed project-level information is available from HUD's Low Income Housing Tax Credit Database.
Estimates of values and transactions prices for apartment properties are provided for national, regional, and local areas by private data companies.
Real Estate Investment Trusts
All REIT web sites, and more information about REITs, can be accessed at the web site of the National Association of Real Estate Investment Trusts.
