It is true that if you sell your home first it will be much easier to buy another one. You will have sufficient funds for a down payment available. You will not need to make the purchase of the new home contingent on selling the old one. You will have completed the task that is the most time-consuming in a buyer’s market.
On the other hand, you need to know your area and how quickly your home will sell, or you may find yourself living in a rental for the time it takes to find and purchase your next home. Consult with real estate professionals, and do your homework about how long homes for sale sit on the market in your area. If you still cannot make a decision, put it to a family vote.
