These and similar questions are some common reasons behind using vouchers/stamps instead of cash.
Genuinely affordable housing is in very short supply and this fact has gotten steadily worse for decades. If we built more basic, decent housing that was a reasonable size, this would solve a lot of problems for a great many Americans. But we have made it incredibly hard, if not impossible, to do this. Zoning laws, federal regulations, tax incentives and financing mechanisms have helped create a situation where those that can afford to buy a house at all are crazy to not get the largest house they can afford and, at the same time, homelessness is on the rise.
It is madness.
In my county, all a Ladlord needs to do is comply with some sensible regulations, like have running water, and he's a section 8 landlord.
A lot of landlords, rent barely inhabitable units, or run down mobile homes, and make a tremendous amount of money.
I knew a doctor, who bought an old trailer lot, and turned it all section 8 units. He made a killing off the government.
The tenants were just happy to not be homeless.
