I recently spoke with a local lender about financing MHP's. He made it sound like his bank mostly focuses on the strength of the deal, but they do also underwrite the borrower(s) as well. I think these smaller banks all have different rules and criteria but this seems to be pretty common that both the deal and, to a smaller extent, the borrower must check out. So that could pose a problem if you give up your W2 altogether. Perhaps if your new employment (or self-employment) is something you've been doing to a lesser degree for a while they will cut you some slack. But I wouldn't want to go "Ready, fire, aim" on something like that. Talk to 3 or 4 local banks (banks that have done MHP loans in the past) and get their take on it before you jump ship.
