This dataset provides a historical overview of the annual national averages for various terms associated with conventional single-family mortgages in the United States. The data spans multiple years and includes key metrics such as the contract interest rate, initial fees and charges, effective interest rate, term to maturity, mortgage loan amount, purchase price, and loan-to-price ratio. Additionally, it attempts to provide a percentage distribution of the estimated number of loans by different loan-to-price ratios and the percentage of loans with adjustable rates, though these specific distributions are not available in the early years of the dataset. This comprehensive data is essential for financial analysts, real estate professionals, and economic researchers to understand long-term trends in the housing finance market.
