The Muskegon house you didn’t buy in 1986
A $300,000 house at 1986’s average index level, tracked to 2026 Q2.
The metro index went from 65.8 (the 1986 average) to 388.3 in 2026 Q2, 5.9× its 1986 level. That makes a $300,000 purchase about $1.77M today.
With 20% down ($60,000) and a 30-year loan at 1986’s average rate of 10.19%, today’s equity is about $1.77M, 29× 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.
