Section 8 may feel like guaranteed money, but they can stop paying or pull back funds at any time for a variety of reasons. The extra hassle isn't often worth the false belief that rent is guaranteed. Depending on your property, you may have all applicants with a housing voucher. In this case you just have to deal with added hassle of long wait times for inspections, crazy accounting, government employee turnover, etc. It's not horrible every time, but I would estimate 1 out of 20 rental situation resulted in a bad tenant, case manager, accounting errors, etc.
