Rebuff hardwoods or go laminate, w/photos

[Justin W.]

HI, I am on my first investment and it is a live in rehab then rent. This is a c+ neighborhood for my area(I think), lower but working class. 

I did not budget properly for flooring and know it is not wise to pay 2-4$ per sf to refinish the hardwoods so they can be torn up in a couple of years so my options are a rebuff(screening) then coats of poly or laminate. I do not want to put in carpet but would consider it.

My problem is I don't know how to gauge what my floors need. I am thinking that for a rental here they simply need a rebuff and coating.

EDIT: photos aren't loading.. Ill work on that
