Here's Where to Get Moving Boxes
If you desire to attempt to save Dollars, offer the buyer a Discount , a % OFF the settling price to accomodate New carpet installation . Typically the carpet is replaced and floors REfinished , to present the house you are selling at the best possible appearance , not showing the wear of your stay there.
Think about IT , which house would you rather BUY ?
A home with New Flooring , or one where you see every scratche and stain left by the former Owners ?
Discount the sell price ,DO NOT Refinish the Floors at all and Sell AS IS , or refinish and install NEW CHEAP CARPET !
