The buyer made it clear she wanted to refinance it in a year once she improved some credit and could acquire an FHA, which I was fine with.

And finally, make certain you hire a good inspector - you can try to get credits from the seller (based on repairs the inspector finds) plus it's essential to know what you're getting yourself into, property and repair-wise.

Remember when you have only 2 units there is usually not much margin to handle vacancy or damage.

How low of a credit score should I accept?

But it's a free country.I would hire an attorney to evict them properly and then seek a judgment for the damages.

Pull out line of credits on them? 

Fantastic to see how well you have been able to do over there, a credit to you. 

It's not out long enough for a bank or credit union to see return. 

They also report the individual to a credit reporting agency so it sits on their credit and hopefully stops them from scamming the next person.

Looking for some opinions on some damage found by the inspector today on a house we have under contract.
