From my experience, they destroy everything.
For years my grandmother would not rent to anyone on assistance of any kind, but when the market had gotten tight, she rented to two in a row. They destroyed two apartments to the tune of $15k.
My business partner has 30+ properties, and he also will not rent to section 8 for the same reason. Luckily most of the time they do not pass the reference check. So they/he can be picky.
The best policy for anyone doing property is to spend the extra money, and time screening your tenants, and have some money saved to wait it out. $500 a few months is better than $15k in damages.
