Hello all.
We have a 1950s house that we are slowly getting fixed up to sell. The kitchen area has wood flooring that has gotten a lot of wear over the years, has some marks from our moving heavy boxes on it, a few places where there is a small space between sections, and a few spots that feel soft underfoot (it may need more supports underneath for our peer and beam house).

Would it be worth it to refinish the floors or just cover over with new flooring? Have seen ceramic flooring at Home Depot and Lowes that looks good, and you can't scratch it. Not sure how that would add to or take away from the selling of the house.

Another issue is there are some stairs to another room where the stairs are soft pine (was here when we bought the house). Our dog has scratched up the wood over the years. Have refinished it before but it just got scratched up again. Is there a finish that seals in the soft pine wood where it is hard to scratch up, or would it be better to just start with new wood?

Just wanting to do some things that adds to the attractiveness of the house when selling it.
