As you go west from Tremont & Ohio city you will hit the Gordon Square around the W 65th area.

I painted the entire interior of one of my rentals for 2k, that one was 850 square feet.

I arrived at that from lots of Googling to find $150/sqft a reasonable price and assuming the house would be 1,100 square feet.

Well not the real one but a 14,000 square foot replica  just outside DC in McLean VA. 

There were two square titles that were damp and covering a basketball size hole in the shelving from continuous water damage (unreported). 

@Greg Wa in City of Cle or surrounding suburbs?

I would think vinyl stick squares would be the cheapest water resistant flooring but it wouldn’t look great over the cracks in the planks.

The 3500 square feet are on a massive corner lot, so there's lots of parking, and the zoning is great at 0-3, so it is actually now okay to be residential multi family or even live-work spaces. 

Attempting to price a rehab by per square foot is a good way to be incorrect and get yourself into trouble.

It is a 500 square foot studio in a co-op selling for $145k.
