Basement Subflooring OSB vs Concrete

[Riley Blake]

Anyone know the pros and cons of basement OSB wood subflooring and pros and cons of a concrete subfloor?

I’m looking at a house in Minnesota that has OSB wood subfloor in the basement. I haven’t heard of many houses like that and wondering what problems I might run into down the road. Concrete to me sounds like the much better alternative. I’m wondering if anyone has ever backed out of a deal because the basement didn’t have concrete flooring.

The only wood subfloors I have seen were put on top of concrete....  Placing wood right on the ground (especially OSB) would deteriorate relatively quickly.  

Are you sure it isn't a wood subfloor such as a dricore over a concrete slab?
