Okay, the floors turned out to be a challenge I don't want to proceed with. We can get someone to sand the floors for us for $1.50 a square foot. They start on thursday and should be finished friday. Way quicker than I could get it done, and it still fits within budget (yay!!).
Part of this is learning what I really can (or will) do myself, and when it's worth it to bring someone in.
Now I can concentrate on finishing up the kitchen and the landscaping.
