To cover hardwood floors or not in rental house

[KENDRA J.]

We are in the process of doing a turnover at one of our rental houses. Carpet is very worn and stained and will be coming out. We pulled back the carpet and the original wood floors (house was built in 62) underneath look ok but will need to be refinished.  We are considering refinishing the floors instead of putting carpet back down. 

Wondering if it is the right thing to get these floors refinished instead of putting carpet back down? I don't have much experience with hardwood floors but have heard they scratch easily?  We will not  be allowing pets in this property.

Any advice would be helpful
