I recommend you make contact with an agent you feel comfortable with in the area you'd like to move to, then have a discussion in depth with that agent regarding the timing of your sale and your purchase.
The timing may be different in different areas of the country and there may be issues concerning the sale/purchase that you haven't made us aware of, or you might even be unaware of yourself.
