Refinished floors worth the investment?

[Andrea Cole]

My husband and I are 85% done on rehabbing our first investment property. It's a 1942 duplex in High Point, NC that we plan to AirBnB. 

When I originally did my budget, I didn't include refinishing the floors but after months of construction they're looking pretty rough. There are gouges in a few spots and the poly is chipping in a few areas. I'm thinking refinishing them is worth doing now rather than later since the place will never be as empty as it is now but my husband is unsure if it's worth the investment. 

Has anyone had to make this choice before? And what did you decide? Just looking for some sound advice or maybe some alternatives (?). The first quote came in at close to $6k for 1400 sq ft, mouldings, and 40 stair treads.
