I was thinking it may be closer to a "wash" or, maybe only slightly more only bc w/ a duplex at least we aren't paying for two exterior wall materials for two sfh?

I'm running into hangups with code section R302.3.1 which seemingly requires not only the floor separating the units to be fire rated but all the walls below supporting that floor to be fire rated (ie all exterior walls and load bearing interior walls on the first floor), which may mean extremely expensive fire rated windows at the lower unit.  

If there is mold, it will usually be A) on the subfloor exterior, joists, and insulation in the crawlspace, or B) in any areas of water damage/water leaks inside the walls, behind tile in bathrooms, etc.

The HOA has an exterior insurance policy for the condos (Image 1). 

First and foremost, as you're changing out the locks on the doors, install doorbell cameras on the exterior to cover entrances in/out of the property.  

So if you build a manufactured house and upgrade everything to 2 x 6 exterior, 16" on center, 2 x 4 interior 2x8 subflooringupgraded to Wind Zone III, trailer hitch wheels removed and set as a permanent structure on n a permanent concrete foundation.

The maintenance differential between a single-family and a two-family is twice the mechanicals, but the same amount of roof, exterior, etc.

Most likely 27.5/39 year property since it's exterior improvements.

I do recommend more exterior pics unless the exterior isn't all that.
