First, target the area you want. Second, consult a Realtor in your home town about finding you a good realtor in the target area. Third, investigate what will be required to get financed on a second home (usually the down payment is larger and the interest rate might not be as low as a primary residence). Fourth, contact the Realtor(s) and interview them on the phone to get a sense of what they are about. Establish email contact so you can provide the Realtor with pertinent information about EXACTLY what you are looking for.
Lastly, make a visit and view some property...make sure the Realtor is staying with your program and showing you houses you are really interested in.
