What happens if the values go down along the way?

I guess the ups and downs are ok as long as you don't have to sell and can continue to make the payments. And taxes.

Well if the value collapses don’t your taxes?

I'm not sure, especially if everyone's house drops in value in a locality. Services like garbage, police, fire, and schools would still would cost the same, right? So the municipality would need the same amount of money, I'd assume.
