So, I would say homes listed in March/April That is probably too small to make any concrete assumptions from.

We are doing 3 bathroom floors (wood and concrete) as well as a basement living room in the epoxy.

The buyer wants us to fill it with sand or concrete.

Going sideways, I went driver door first into a concrete culvert with a large concrete drainage pipe protruding.

And as always without concrete proof, I, like most others here will just be blowing hot hair.

We had so much snow there was no way to evaluate the concrete conditions.

Get the faux granite Formica or polished concrete overlay if you can't justify real solid stone.Update your bathroom fixtures.  

I'm sure every place is different but I wasn't able to locate concrete rules from the companies I looked up.

I'd suggest asking some local pros what their thoughts are about the Polish Hill neighborhood. 

I have an addiction to large fish tanks and the concrete floors are certainly very useful for people like me that are planning on putting thousands of pounds of water in their living space.
