I have moved a lot. And on move in day (Possession Day) excited about our new home, many times we discovered that the Sellers had left behind personal items, some of it essentially garbage.
There are always bumps in the day, but as Sellers, don't contribute to this already hectic day by leaving behind unwanted items such as:old broken step ladders, 10 year old paint cans, old vinyl flooring, rusty push mowers. You get it.
If you think the Buyers may want something of value (I repeat value!) that you don't need in your next home, reach out to the Buyers through your realtor and see if you can leave it behind. Don't assume. Buyers - make sure your purchase contract states that the Seller will remove all personal items and debris from the condo, balcony, storage locker, end of the parking stall. For a house, from the garden shed, the yard, the garage, the house!
This situation reminds me of the old adage I learned growing up: Do unto others as you would have them do unto you. Sellers: the day you move out may be the day you move in to your new home, hoping to find it spick and span. N.B. Spick and Span was an all-purpose household cleaner introduced in 1933. I am not that old but we always used that expression!
If your new home is clean and clear of debris, you will be very appreciative of the the Buyers and will be left with a more positive moving experience.
