I’m about to buy an older home (88 years old). 3 rooms (totalling about 500 sq ft) have wood floors. 1 room has new hardwood. The other 2 have the original oak floors, but were stained differently by the seller, so all 3 rooms look different. Should I refinish all floors to match, or give in and replace online prescription everything with bamboo? There are some flaws in the floor right now that refinishing wouldn’t repair. What kind of price tag would I be looking at with different options?
