Hardwood floor refinishing question

[Adam Craig]

I got a quote to refinish the floors for $3200 or $2.50/sq ft. This includes the first floor, the stairs going up, and 3 bedrooms upstairs. I have used him before and he does good work -

I do this because I like not having to replace carpet but I was thinking I might have him refinish everything except the 3 bedrooms upstairs. Do most tenants prefer carpet in the bedrooms or should I just pony up the money and be done with the floors for years after refinishing.
