I take it you haven't worked there very long?
While I'm not certain, I would think a few "steady" years showing a decent income would work. Or, you could save your butt off and I think (here anyway) if you have 20% down they don't look so closely. Or, there's the not so nice thing where you'd "pay" full market value on the house but only mortgage 75ish percent of the value. You'd have to compensate the sellers for the property gains. But you didn't hear that last one from me. I think that's highly frowned upon.
