I have a friend in the car repair business.
He buys old houses, and fixes them up just enough to pass whatever inspections the Section 8 folks set, then he rents them section 8.
Supposedly the tenants pay a portion of their rent.
My friend says that he doesn’t really care whether or not the tenants pay their share, although if they do that is a bonus. He makes enough off the Government to pay the house note,and when the note is paid off the property is his free and clear, and didn’t cost him a penny. He has a lot of properties, so it must be working.
