the deal about extreme home makeover

when they give these broke families a designed up the butt house (exp. fish tank sink, 100 new electronic devices, spa) how do they support themselves after they leave, or do they all cash out on the house and appliances?

I’ve heard that at least one family was put into some sort of deep financial trouble after the amount of improvement made to their property sent their taxes skyrocketing. I’ve never seen anything verifying this, so it could be false.

I would think that instead of giving the one family a super mansion, they’d spread out the funds to 3 or 4 families and it would still make a significant improvement while helping more people. But then you won’t get the same ratings as showing the design genius that can be put into the one palace.
