I'm looking at a 25 acre property in NC with three homes on it, one move-in ready cabin, a move-in ready park model on a foundation, and a third ranch house in need or repair. The idea is to purchase, live in the par...

However, there are also 2 non-conforming spaces.

When building non conforming real estate cities want you to build properties that will INCREASE the tax base, not lower it by building a much smaller and lower value home.

@Sonam GillSonam,Your conversion from a 3 family to 4 will require a change of use and more importantly move your unit from residential to commercial which triggers a litany of zoning requirements to conform (parking, FAR, refuse, etc.).

Would a non-conforming loan work for this situation?

If the property has split utilities and has been used previously as a duplex you can submit for it to be registered as a non conforming duplex. 

Especially if you're not going through the hoops of conventional/conforming.  

States may or may not conform and postpone their returns, or they may choose a different postponement date.

States may not conform to federal and continue to be due April 15th.

If you are above the conforming loan limit of $548,250 then your rate will be hit a little.
