Can ADU's Cause a Big Problem?

[Ramon Wilson]

I have heard from a couple of lenders that conventional loans are not available on duplex, triplex or 4plex properties that add an ADU (an SFR with an ADU does qualify for a conventional loan). This is not an issue of the property being considered commercial (ie, 5+ units), but rather fannie mae guidlines. If this is true then adding an ADU to a 2 to 4 unit property would require any future financing to be the much more expensive (eg, non-QM) and potentially limit the buyer pool if it was sold. Seems like a big con to adding ADU's on 2-4 unit properties. Is this correct?
