I suspect H4H homes are less likely to have issues than are government housing programs. I suspect that the pool of deserving low income people who will be good stewards of the H4H largess is shrinking and they are getting more problems as they get bigger.
I agree with you. When they were small they had much more ability to handpick good candidates - those that were poor through relatively little fault of their own. Something like having a disabled kid, for example, can cause a familiy that would otherwise be middle class down to 'poor'.
On the other hand - I still maintain that most poor people are that way less due to income than due to spending/money management habits.
And yes, they likely DO have a default rate higher than people in better financial situations. Just because they've been more or less given a home doesn't mean that they're in better financial condition, and many will mortgage their home in iffy financial deals in an effort to lever themselves up higher, or to cover day to day stuff. Example: the family who got that house from the TV show, then opened a mortgage on it to open a construction business that ended up failing when the housing market went bust and they couldn't make the payments.
I understand the reasoning behind doing it - but I also like being paranoid and having equity in my house.
