Hi Lana, and thank you for your question.
In order to qualify for the best interest rate with a manufactured home, you want to make sure it's classified and financed as real estate, not personal property. That means the home must be at least a double wide, on a permanent foundation. Your best bet for getting loan approval on a manufactured home, unless you have perfect credit and 20 percent down, is probably a government-backed loan like the FHA or VA mortgage program. Manufactured houses today can be constructed and designed very nicely, and often look like traditional "stick-built" houses.
