From https://www.usinflationcalculator.com https://www.usinflationcalculator.com I get that the value of the house should have increased by 92.4% from the purchase price in 1993. The last sale (four months ago) was up by 438%¹. It gets worse if I go from the sale price in 1997 where inflation shows 73.2% but the increase was 525% ⸻⸻⸻ 1. To be explicit, the house sold for 5.48× more than the purchase price.
