Abstract

Federal Housing Finance Agency. House Price Index: House Price Index - All Transactions | Seasonally Adjusted: Non-Seasonally Adj, 1975/1 - 2018/1. Data Planet™ Statistical Datasets: A SAGE Publishing Resource Dataset-ID: 057-001-001 Dataset: Presents an index (1st quarter 1980=100) of US single-family home prices, by state. All transactions include new purchases and refinancing of conforming, conventional mortgages purchased or securitized by Fannie Mae or Freddie Mac. Only mortgage transactions on single-family properties are included. Conforming refers to a mortgage that both meets the underwriting guidelines of Fannie Mae or Freddie Mac and that does not exceed the conforming loan limit. The House Price Index (HPI) is a broad measure of the movement of single-family house prices. The HPI is published by the Federal Housing Finance Agency (FHFA) using data provided by Fannie Mae and Freddie Mac. The Office of Federal Housing Enterprise Oversight (OFHEO), one of FHFA’s predecessor agencies, began publishing the HPI in the fourth quarter of 1995. The HPI is based on transactions involving conforming, conventional mortgages purchased or securitized by Fannie Mae or Freddie Mac. Only mortgage transactions on single-family properties are included. Conforming refers to a mortgage that both meets the underwriting guidelines of Fannie Mae or Freddie Mac and that does not exceed the conforming loan limit. Conventional mortgages are those that are neither insured nor guaranteed by the FHA, VA, or other federal government entities. Mortgages on properties financed by government-insured loans, such as FHA or VA mortgages, are excluded from the HPI, as are properties with mortgages whose principal amount exceeds the conforming loan limit. Mortgage transactions on condominiums, cooperatives, multi-unit properties, and planned unit developments are also excluded. The HPI is a weighted, repeat-sales index, meaning that it measures average price changes in repeat sales or refinancings on the same properties. This information is obtained by reviewing repeat mortgage transactions on single-family properties whose mortgages have been purchased or securitized by Fannie Mae or Freddie Mac since January 1975. http://www.fhfa.gov/DataTools/Downloads/Pages/House-Price-Index-Datasets.aspx Category: Housing and Construction, Prices, Consumption, and Cost of Living Subject: Single-Family Housing, Housing Market, Home Prices, Price Indexes Source: Federal Housing Finance Agency The Federal Housing Finance Agency (FHFA) was created on July 30, 2008 by the Housing and Economic Recovery Act of 2008.
