As Randy mentioned earlier,there is the option of selling or renting your property. Depending on your financial options, you may want to rent your next home short term. This will alow you time to get to know the area and to find that "special home".
The purchase of a second home will require a larger down payment if you are not planing on paying cash. You can also lease your exhisting home and call that income property and consider your next home purchase your primary residence. (check with your lender for details on income properties).
If you are considering purchasing a home, and obtaining financing, you do need to visit a lender first. The information you obtain from your lender will deffinately help you determine which real estate move is best for you.
Best wishes on your move.
