@Jeff Whelan Yeah it seems @Christopher Phillips didn't understand that you're talking about a house you've taken over the payments on.I'm not sure about lenders in the US but here in Canada if the seller shows them the lease they will only credit 50-75% of the income toward their income for the purpose of DTI calculation.That's probably the best your seller is going to get if you've taken this property over on a lease option.

He is one of two people applying to rent the apartment, and is a high-functioning autistic adult.

I'm trying to find a strategy that satisfies the below requirementsMotivates potential tenants to apply and lease quickly (a weak pressure sale tactic?) 

Father's removal will be a gift to daughter for federal tax purposes and a gift-tax return will need to be filed, and unused lifetime credit will be reduced, or, if already all used, gift tax must be paid. 

Does this include credit unions?

What strategies would be best to apply in this scenario. 

The $200 of cash flow, which comes from the tenant not you, if applied to the mortgage would allow you to pay down the balance and do away with the PMI.

Anyone that reads my posts knows I'm not one for the hard sell,  but I think credit where credit is due, and I know the BP community is always interested in information about on-the-ground changes in popular RE markets.Thanks to you and @Caleb Heimsoth , as always, for your input!

Has anyone try  to dispute a Late payment charge on your Credit score?

We also can meet all other requirements for borrowers (credit score, DTI, etc).
