Sorry I've absolutely combed forums looking for the catch in this method and I can't seem to find these specific answers..BTW, thanks SO much you both are insanely helpful.

It has to be very specific(with contingencies), I’m currently having problems with my partnership as one of the partners isn’t doing his part.

Your specific lender may have other stipulations/restrictions on the loan, so you'll want to read the contract.

@Paul LangeThis is just my personal advice.Don't sell real estate unless you specifically build or renovate with the intention to sell.Rentals should be held onto forever-if possible.Just my personal opinion-1000 people will disagree, but that's just my philosophy on real estate that can be rented. 

So when you are interviewing lenders, ask that specific question - "how do you use rental income when it's not on tax returns" - and see what they say.
