It is also difficult to get rid of section 8 bums. Once a landlord takes on section 8 bums, government at some level will fight to make you continue serving them.
You must have some experience with this. :-)
In addition to getting rid of them, the govt. comes in and demands repairs before any more payments for the vouchers will be made. IOW, if the tenant tears the place apart you have to fix it, then the govt will pay the rent. The tenant tears it apart again and you fix it again or you sell the property to someone like me.
I fight to empty the entire building. I then fix the building and begin renting to people with some degree of credit. The rents I can charge are less (sec 8 lures landlords in by paying above market value) but the repair costs begin to drop dramtically.
