The metro index went from 48.9 (the 1979 average) to 390.7 in 2026 Q2, 8.0× its 1979 level. That makes a $300,000 purchase about $2.40M today.

With 20% down ($60,000) and a 30-year loan at 1979’s average rate of 11.20%, today’s equity is about $2.40M, 40× the down payment. The loan would be paid off by now, so the equity equals the house’s value.

The S&P 500 index fund this site compares against (the TSP C Fund) begins in 1988, so there is no market comparison for a purchase before then.
