"Every plan to move should include a Plan B."
Moving to a new home doesn't always go the way you'd like. If it did, you would sell your home quickly, then settle on a perfect new home just before your household goods pull up at the front door. Unfortunately, details often get in the way of what's supposed to happen on schedule.
If you're planning a relocation, make sure you develop alternate plans in case something doesn't go as planned. For example, talk with your lender about a bridge loan, in case your old home doesn't sell before your new home goes to settlement. The opposite could happen too--a lag between vacating your old home and settling on your new one. Having a plan in place for temporary housing could come in very handy.
