It actually depends on the desired outcome both in purchasing your new home and leveraging your current home. It is usually easier to find you new home than to sell your current home for a few reasons. I just completed a purchase with a family that are now selling. I also have another client selling first then purchasing. It depends on your goal both long and short term. I have a blog that gives good info. On both buying and selling. I would be glad to answer any questions for you and your family on this important matter for you both.
