ATM the floors are covered with old, crusty carpet that we want to remove before we move in. It looks as though underneath is lovely cyprus floorboards and they look like they have been finished a long time ago (we can see the boards in the cupboards). FYI the house was built late '60s/early '70s.
Some questions:
1. Is it likely the carpet is glued down, meaning the floor boards need sanding to get rid of the glue?
2. If we are wrong and the floorboards are not finished, is it okay to leave them unfinished?
3. My dh is concerned that when we take the kitchen out (a couple of years down the track), where the old cupboards were the floorboards will look funny and we'll have to do the whole living area again to match it up. Is this likely or will it be easy to finish a small spot and match it to the rest of the floor? It's also a problem in the entry area which is currently cork flooring and cork walls

Thanks in anticipation!
