As already mentioned, most of the section 8 tenants are extremly well versed in Landlord/Tenant law, so make sure that whom ever you use knows there stuff as well.
A couple of things to remember about section 8:
1) Starting contracts are for a minimum of one year, which means that unless the tenants are in serious breach of contract (ie: not paying rent) it is almost impossible to get rid of them during that first year.
2) The property itself will need to be certified every year (by HUD/Section 8) that it passes the maintenance inspection. Any dammages, caused by the tenants, will still have to be fixed in order to get certified.
The advantage to Section 8, is that you can be as restrictive in your screening criteria as you would be with non-section 8 tenants.
The positive is that this can be a good way to get good tenants, if you take the time to screen them properly.
