If you're moving, it's kinda hard to buy a new house the same day you sold the old house.

In the car dealer business, cars usually sit for a month on the dealer's lot before they sell. Car dealers hate that, because they borrow money to put the inventory on the lot, and pay interest on that money.

It's the same for house sellers. Leaving a house vacant cost thousands of dollars a month. Sellers aren't letting it sit vacant for fun. When I've sold a house, I was painfully aware of the vacancy costs, and always tried to price it to get it sold ASAP.

If I remember correctly the house should sell in 2-3 months (earlier and it was priced too low, longer and priced too high).

Interestingly realtors houses stay on the market longer and sell for more than their customer’s houses …

Realtors have different incentives in selling other peoples' homes than selling their own.
