It only needs a new kitchen, new bathroom, and some new flooring.. all very easy since I'm a contractor and the unit is in great shape.

I've done the small jobs like tile for the bathroom (small area), drywall, paint, and even both baths in my own home where the sink and vanity were replaced.

How big is the bathroom?

After test were done they found mild in my bathroom and bedroom also.

Some renovation to the kitchen, bathroom, and if needed to, build additional bedroom to create a certain niche in the market for my property to stand out.

Im still going after the deal, but might have to get a little creative on how to get this guy into contract.The deal has amazing views of the Ohio River and Downtown Cincinnati and has the potential for a condo conversion.Renovation includes:New kitchen, new cabinets, and new appliancesNew bathroom, new vanity, and new flooringNew flooring throughout the apartments (Faux wood floor)New sliding glass doorsNew fencing and signageSeal and Strip parking lotAdd an fire pit and BBQ station to capture the view I will update as the project continues, going out to see the property October 20th.

I was searching for some sort of guidelines that would give me an idea of what certain "generic" costs would be to, say, the bathroom, kitchen, etc., and this would be of course per sq ft cost. 

That assumes touching every surface and major upgrades everywhere (e.g. kitchen and bathrooms), but not replacing all mechanicals, roof, electrical, plumbing, etc.If your numbers are accurate you're buying at 84% ARV less repairs, as pointed out by Jeff S Na.  

We do have good attic access.I am still spending ~$9k for the central air, condensing unit, ductwork, condensate drains, and two exhaust fans for the bathrooms.  

I think we could get a higher price if I re-arranged the master bathroom, which would require knocking out a wall that connects to an oversized laundry, closing in a passage to the kitchen, and moving some plumbing around.
