The National Association of Realtors' Fixed Rate Mortgage Housing Affordability Index (HAI) declined 3.8% (+5.3% y/y) during May to 97.2 after falling an unrevised 2.3% in April to 101.0, following moderate gains in each of the prior four months. The recent high was 104.9 in September of last year. The level of home affordability remained 8.1% higher than its low of 89.9 in October 2023. The latest level was 45.8% below the high of 179.2 in April 2020.
The decline in affordability in May occurred as the median price of an existing single-family home rose 2.3% (1.3% y/y) to $427,800, and mortgage rates rose to 6.90% from 6.81% in April. The price compared to the record $432,900 in June 2024. The rise in mortgage rates left them above their a low of 6.26% in September of last year, though below a 7.70% high in October of 2023. They remained well above a December 2020 low of 2.73%. In May, the principal & interest payments rose 3.3% (-1.1% y/y) to $2,254 per month, well above the most recent low of $984 in February 2020. Monthly mortgage payments averaged a higher 25.7% of income during May, up from a low of 14.0% of income in April 2020.
The rise in housing costs in May was accompanied by a deterioration in median family income. It fell 0.6% (+4.1% y/y) to $105,204 after rising 1.0% in April. Qualifying income rose 3.3% (-1.1% y/y) to $108,192 after rising 3.5% in April.
Housing affordability declined m/m across the country in May. The index fell 5.7% (+3.1% y/y) to 122.7 in the Midwest, though it remains the most affordable region of the country. In the South, the index declined 2.5% (+7.5% y/y) to 103.0 and the affordability index in the Northeast declined 6.4% (-1.3% y/y) to 86.1. In the West, where homes are the least affordable, the index fell 2.4% (+5.6% y/y) to 69.3 in May.
The Housing Affordability Index (HAI) equals 100 when a median-income borrower qualifies for an 80% mortgage on a median-priced existing single-family home. The HAI had exceeded 100 in each month since July 1990 and reached its all-time high of 213.3 in January 2013.
