Short answer
Yes. A modular home is built in sections in a factory to the International Residential Code adopted by the state, then set on a foundation, so lenders treat it much like a site-built home. That's different from a manufactured home built to HUD's federal code, which has extra rules. Fannie Mae has no minimum width, size or roof pitch for modular homes.
How is modular different from manufactured?
A modular home must meet the building code the state adopts for houses, the same as a stick-built home. A manufactured home is built to HUD's federal standards and carries a HUD label; it can get a mortgage too, but with added checks on the foundation and title. See the manufactured homes guide.
How is a modular home appraised?
Much like any home. The appraiser picks the best comparable sales nearby; they don't all have to be modular, though similar homes help. Because build quality varies, the appraiser notes the features that affect value. Keep the builder's papers and any upgrades list handy.
What if I'm buying a new modular home?
If you're buying land and having a modular home set on it, you may need a construction loan that pays the builder in stages. See the construction loan guide and buying new construction from a builder.
