What is the Repeat-Sales Method?

The repeat sales method is used to provide information about housing price indexes to investors, home buyers and sellers and the housing Industries as a whole.

How is the Repeat-Sales Method Used?

An example of an index with a random sample is theNational Association of Realtors (NAR) Median Index or the Census Bureau Median Index. The repeat sales method was primarily deployed to serve as a solution to the structural issues. It was created to closely monitor the price changes of real estate between the current sale and previous sale. The method is useful in calculating the average sales price and it offers a precise alternative to regression analysis. The repeat sales have been able to account for changes in home prices based on sales of the same property. This has been able to curb issues that may arise from differences in the price of houses with similar or varying features. One of the striking disadvantages of this method is that it does not account for homes sold within the specified time of the report and this is also part of market activity.
