okay, nobody asked this question---but, why would you want to lease to someone with bad credit?
why not?
here's some out of the box thinking
if the tenant wants to buy the house in a few years then give them the first right of refusal to buy it
collect 2 months up front and 5% closing costs
work with them to refinance the house in their name which may take 2-3 years and collect your commission
if its just a straight rental, depending on your location, you might get some negative cashflow like in california. avoid this burden by structuring a triple net lease which the tenant will cover everything. per the IRS code, we give them the tax deductions while leasing.
