Manufactured homes are generally financable with a few stipulations:
FHA transactions require manufactured homes to have a foundation inspection or structural engineer's report. For VA transactions, the appraiser will decide whether a foundation inspection is necessary.
And the appraiser may check to see that L&I inspections have been obtained. Check here to see the kinds of modifications that require an L&I permit. I recommend that real estate agents look for things that couldn't possibly be original to the home. For instance, if your 1984 manufactured home has a fancy new tankless hot water heater, it probably needs an L&I inspection.
Don't worry if permits weren't obtained from L&I at the time the modification was made. They're fairly easy to get after the fact and not terribly expensive.
Manufactured Homes as ADUs
Two manufactured homes on one parcel is generally unacceptable (one of those strange lending guidelines I've never understood). However, a stick-built home with a manufactured ADU is generally acceptable for Fannie, Freddie, and FHA. The typical guidelines still apply (built after 1976, installed on a permanent foundation, etc.). And the manufactured home must be the ADU; it can't be the primary dwelling unit.

* The exception is USDA transactions. USDA requires homes to have been manufactured after January 1, 2006. This is a pilot program and is only available in certain states (Washington is included). Otherwise, the home must be brand new and never occupied.
