Whatever turbulent feelings you're experiencing right now, there are plenty of practical matters that need your attention. Keep in mind the following considerations to help the whole process go more smoothly. It's a good idea to place your home on the market as far in advance as possible of purchasing a new one. If you find a new home first and then try to sell your present home, you may wind up with two mortgages. If this does happen, ask your real estate agent or banker about a bridge loan to help you make the double payments.
Lenders use the same criteria for offering bridge loans as they use for mortgages.
Keep in mind that when people move, sell and buy, there usually is a domino effect. Closing and moving dates have to be coordinated, and the more firmly everyone commits to a window of dates and sticks to them, the better for all involved. Put all agreements about dates in writing, and protect yourself by negotiating financial penalties for failure to comply. If you are going to sell your home yourself, consider hiring a professional real estate appraiser to provide you with an estimation of your homes present market value. A home that's visually appealing and in good condition will attract potential buyers driving down the street.
