I have also utilized owner financing for longer periods of time, including personal residence and 2 barrier island houses on the coast of Florida.  

Quote from @Alan Asriants: Here is a note I found from Fannie mae: ADUs are not eligible with a 2-4 unit dwelling, or when a manufactured home is the primary residence.

Your primary residence - if you've lived in it for 2 out of the 5 years prior to selling you'll get the $250K/$500K tax free iike @Clint Galliano said. 

And how does the time the Airstream is just sitting in my driveway at my primary residence count?

I guess I could do some work-arounds -- maybe reserve one unit in the first purchase for use as an AirBnb, and reserve my own time in it when needed - instead of claiming it as a primary.Are either of you (or anyone) familiar with a finance product/loan that will allow me to purchase under $150,000 (w/ strong credit) and do much of my own work and live-in a portion as a primary residence?  

What zoning code could I request a zoning variance or rezoning that would allow us to have the 2 livable units on parcel, one primary residence and one additional living unit (known currently as ADU)?
