Yea, I don't understand myself, at least if they are in the US. Could be very location dependant, but mostly housing prices greatly increased since then.

I don’t want to sell, I was hoping to be buried in the backyard when I died.

But you haven't explained why it was a bad decision to buy.

My mortgage is up a thousand bucks due to interest rates. It was a an FHA loan so it made sense at the time
