The good of it is they require inspections which keeps your property up to date and most tenants do not want to lose the voucher.

We are in a beach market, so we get calls all the time from voucher holders who live in other parts of the country and say they want to "port in" to our market.

Sometimes, they run with the tenant as avoicher holder other times, the voucher is tied to the unit.  

The rent is government guaranteed to show up on the first of every month, and the tenants aren't likely to make waves because they don't want to face eviction and a loss of their voucher, which would be devastating for them.

SB 1053 (Leno) forces residential rental property owners to participate involuntarily in the federal and local government's voluntary Section 8 voucher program.

A voucher pays his rent and they will stop after June

I know out here in East TN you get a voucher which covers $X amount, and if you find a place for more than that you have to cover the difference yourself, the caveat being that the total you pay in rent cannot exceed some percentage of your available income - i.e. they're not going to give you a voucher that you can then use to go live in a palace by paying the difference. 

If the tenant loses their voucher over this, that is on them, not you.

The tenants know that they are not allowed to have anyone else not on their voucher live with them, but I have a tenant who has moved their boyfriend into the unit.

I have one tenant with a credit score over 600 and she has a HUD voucher.
