Land titles and taxes, some people are only staying in their current homes because taxes are antiquated and aren’t updated. They wouldn’t be able to afford paying modern taxes, but also, everyone else is stuck paying for shortfall. It’s a shitty system.
It’s a real unfair system when an old million dollar house has $100 a month taxes while a modern $70k condo has $1,200.
Partly the reason why people live in tornado alley, cheap taxes, it’s just worth it to some people.
