Am I able to use comps for the unit I've occupied or if it's identical to the other side, use that number? 

It's expected and not usually penalized unless a competing offer of identical price has none. 

@Matt M.Hopefully they get me confused with the singer and steal his identity first.I agree, I still have family there too so if I ever wanted to go back it’s always an option.

I contemplated the idea of just changing the design concept to have it be attached to the main home, but even in that scenario, the explicit CCR's against even renting one room seemed too controlling to be sane, considering that if this worked as we wanted, there were like 200 other nearly identical situations with lots with homes in that neighborhood that we would have just wanted to rinse and repeat that strategy.

When we rolled our construction loan into a mortgage, we took cash out on that and bought the vacant lot across the street, and will begin construction on an identical duplex as soon as we get the permits and construction loan.Since my partner is semi-retired, he doesn't have the energy to put into locating/fixing/flipping etc.

I was told by this bank in Cleveland that they couldn’t verify the identity of my LLC and closed my account under PATRIOT act. 

Mine happen to be Mexican, and they can prove identity via Mexican government issued "matricula consular" (forget exact spelling).. they look like drivers licenses sort of.

It DOES have new appliances and HVAC, but is over $5,000 more than the other places that are identical in the same complex. 

I am in an identical REI stage as yourself with almost the same short-term plan.
