Brunswick, GA Federal Housing Finance Agency Home Price Index (FHFA HPI)

The Brunswick, GA, Federal Housing Finance Agency (FHFA) House Price Index (HPI) is a weighted, repeat-sales index that measures average price changes in repeat sales or refinancings on the same properties. The index covers single-family homes and condominiums. The HPI value for a particular geographic area is the weighted sum of the indices for all counties in that area.

The HPI is a valuable tool for measuring house price trends at different geographic levels. It can be used to measure house price changes over time, to compare house prices across geographic areas, and to identify areas where house prices are increasing or decreasing at a faster than average rate.

The HPI is based on data from Fannie Mae and Freddie Mac's Single-Family Mortgage Database (SFMD). The SFMD contains information on every loan that Fannie Mae and Freddie Mac have purchased or securitized since January 1, 1975. The database includes information on the property's location, loan amount, interest rate, loan type, and other characteristics.

The HPI values are calculated using a "repeat sales method." This method compares the sale prices of properties that have been sold more than once over time. When multiple sales of the same property are available for a given period (typically four quarters), they are combined into a single "repeat transaction." The resulting estimate represents the change in average home prices in that geographic area during that period.
