Thankfully, we’ve already hit the mark on about half of the criteria you mentioned.

Both are located less than 5 miles from the airport access and within 3 miles of each other.

The property was finally sold to a developer who built a 3-story structure housing 6 condos that sold for half a million each.Getting variances is quite time consuming in our area and I attended quite a few community board meetings which one has to attend before going to a zoning board meeting.

I currently own 1 SFR that i've owned for a year and a half and used my FHA loan on. 

The probem is when you have FHA because there is a 100 mile rule. 

I still don't like the ADU idea unless you plan on buying half of his property overall so it's all equal.

Generally, the further you go from a city's center—about 20+ miles—such properties become more common.

Seller disclosed leases and may have kept half of deposit.

I would contact other facil and see if they are looking for more spaces. 2) Co-Living / Rent by room strategy - I would try to turn that half bath into a 3/4 or full and then it could work very well.
