Should I refinish it the "normal" way with sanding, stain and 3 coats of finish?

I'm always a fan of keeping hard wood flooring.Perhaps your question should have been asked earlier, before you sanded and refinished it.

We refinished the existing hardwood, updated the kitchen and bathrooms, set new tile and backsplash, and added a utility room.

Those wood floors may clean up with a refinish...

remove carpet and refinish sub floor, replace countertops, add kitchen appliances, move a wall to make space for a proper staircase, add a parking spot, replace oil tank if it isn't already a deal killer.Exit: hold as rental long term, sell on a lease optionAny thoughts would be much appreciated.Thanks

More people are into re using stuff but it takes forever to match pieces and often needs re finishing etc.

Here are the backsplash tiles we are going to install (have not done it yet)Refinished cabinets and counter!  

Some of the other projects i have tackled include: roofing repair, gutter replacement, deck building, window replacement, drywall refinishing, electrical work, hardwood flooring, wall and floor tile and cabinet refinishing.
