Cost to finish unfinsihed Basement Remodel to 1BR 1BA 1150 sq

[Leon Gray]

I am new to this site and am jumping into a rental property/landlord. I am purchasing a home in downtown Atlanta. Lower Westside (I think) is not far from GA. Dome. Not in historic district permits should not be a problem. I just got Radon mitigation and Waterproofing down. The home already has two windows, but I know that it will/should need another window. It already has outside door entry access.  

I would like to know the ballpark figure and what it will cost to finish the basement into a bedroom apartment. I would like to have like a mini bar. I will need to install a bathroom.  So, ballpark figures are from electrical, plumbing, flooring, drywall, and ventilation.  I am figuring another 4k-8k for appliances etc..

Thanks in advance,
