It's hard for me to imagine suburban office / retail getting hit harder than it already has, and a small building for small companies in the services field feels interesting to me - right now that's a "Feel" and I have to wrap my head around whether data supports this hunch or not, but I do at the very least like the fact that office has been hit so hard, and seems to have no net new supply coming online. 

Or find a property that is under-utilized or has below market rents.Otherwise, you could also do the OPPOSITE of the great advice from @Jonathan Greene and buy a property with multi-bed units or live in the larger unit and rent out the smaller unit - while getting a roommate(s).

This is a 2500 sq foot 3 bed 2 bath both sides.

As an investor, I don't believe in ever paying retail.

All calculations suggest great investment for 4 bed 3 bath in good school zone, however once the tax estimator goes from $2200 to $9500 due to lose of tax credit from not being a primary residence it hard to see how to get property in SC.

This is the same process a national retail store chains use to determine store locations and what to stock.

That's why I think investors are not your friend, you want retail buyers.Have you talked to the neighbors on all sides of you? 

I have 2 large cabins (2,000 and 2,500 sq ft) I'm holding and another 2 bed 1,500 sq ft cabin just about done and another two that are under construction for holds.

I had a realtor ask if I had any other 2/3 bedrooms so happy to connect you with them if you have a 2/3 bed?

A two bedroom 1,300 sq ft cabin is going to go for way less than a 2 bed, 2,400 sq ft cabin.One of the issues out there too is that some are setup as legal 2 bedroom cabins because of the septic but then they have lofts and such that allow you to rent them out as 3 or even four bedroom cabins to improve the rent.You mentioned one nearby you with a similar layout.
