The expectation that is normally in writing in the Purchase Agreement is that you will leave the house in substantially the same condition it was in when the Purchase Agreement was signed and “broom clean”. This means that you should not leave things that you don’t want anymore in the house or garage – throw them out on the last garbage day. If you have items that you think the new owner might find of value, like extra paint for a room, or extra furnace filters or anything else that a normal homeowner might want, have your agent ask the buyer’s agent to ask the new owner if he wants the items left or not.
Anything that is left behind becomes the property of the new owner and he/she is not responsible for storing or caring for your stuff, nor is he/she obligated to give you back something that you “forgot to take.” If you have items that you wish to leave and come back to retrieve, you must have a written agreement with the buyer to cover those items and the arrangements that you have agreed upon for them. Occasionally, buyers and sellers may agree upon things like the seller returning to dig up one or more specifically identified plants within an agreed upon timeframe.
