Based on what you've said, it seems to me that there are really only two solutions available:See if he can get the city/county to give an exception on allowing him to continue to be grandfathered in to the old building requirements and then getting the boundary line adjusted.     

Hey Petr, I'm based out of Columbus and looking to expand to Cincinnati and Cleveland as well.

Not sure if interesting but my buddy just launched a real-time leads list for off market properties based on publicly accessible data: tax delinquencies, probate, pre-foreclosures...etc.

If you’re in the real estate world in any capacity, especially if you’re interested in the same market areas (primarily Forsyth/Guilford county) then I’d love to connect and touch base! 

I haven't been investing long but I have about 990,000 in equity (estimated based on sales price of comps in the area). 

 @Owen RosenI wonder how much of this is based on the insurer you have, the amount of properties they insure for you, and the type of claim you file for.

I don’t know how bad cause I’ve never really dealt with mold before but it’s in about every room and the highest point is about thigh high from the base boards. 

Is there a certain cost per unit I can expect to pay based on the condition of the building? 

Mix and match depending on your ultimate goal and plan.

However, it may be feasible to cut along the grout lines and remove a section of the tile, perhaps a 3'x3' area right inside the entryway, and replace it with a different flooring material that matches the tile but offers enhanced slip resistance.
