No clue on the financing other than to say I know that in the best of times mobile homes were a challenge...in this market....best to rely on the experts.
As for the appraisal side - similar challenges exist as the definition and criteria constantly change - I'm an appraiser as well as broker.
A quick Google Search before you answer may save egg on your face.
There ARE programs for "mobile" homes through FHA if your "mobile" home is no longer "mobile". Call a good lender that is FHA certified lender and get the specifics, and according to FHA's website,
http://www.hud.gov/buying/loans.cfm (look halfway down the page for mobile home info)
FHA even allows loans for folks that own the home, yet place their home in a mobile home park. To be honest, I know of no lenders that offer that, but FHA's site says THEY offer it.
I am not a real estate agent, and rarely answer questions that are directed to real estate agents. Perhaps when it comes to financing, especially in this ever changing market, if your not sure, it is better not to answer questions about financing. Jim Ryan, Home Savings of America.
There are different leveles of mobile homes, manufactured homes and then modular, if it has a hud stamp, it is considered in the mobile category. Value is based on whether teh walls are paneling or sheetrock.
Good luck with your purchase
