You could call someone that refinishes bathtubs , they have an epoxy that they spray .

I was just told we pay $225 flat to refinish and $30 additional if it needs prep work.

Needs: New roof; possible foundation work (needs engineers report); possible plumbing work (old copper pipes); possible HVAC (has gas central heat and window ACs, would need central air, but seller may be in the process of updating) complete indoor rehab including floors; counters; light fixtures, refinishing cabinets; painting or otherwise fixing wood paneling.

going to convert the 1/2 bath to a full bath, refinish the wood floors throughout, gut and remodel other full bath and same with Kitchen.

Are you saying you are going to keep the floors and just refinish or are you planning on ripping them out and replacing them?

My plan is to replace a couple windows upstairs, fix a few minor drywall issues, and paint, as well as refinish the cabinets and change hardware, and landscape. 

Roof repairs are 6K - 8K depending on additional damage (two estimates) The house can easily be rented as is without making any cosmetic updates, but to get a higher sale price all you would have to do is refinish existing cabinets in kitchen and bathrooms 1K - 2K I took 6 homes recently sold in the neighborhood around the same square footage and average them out to 225K for ARVHas to the potential to be higher with unfinished basement!

Refinish floors?

Note cool little seating in dining room, will be refinished: Another view of dining room showing Butler's pantry door.
