It is possible, but make sure you have a good real estate attorney. I actually started looking in my current town by going with the listing agent of the first house we looked at. We didn't really have any interest in that house, but the agent seemed very knowledgeable about the town/neighborhoods, and tried to sell the town, and not just the house (showed us nearby parks, golf courses, community centers, libraries, shops, etc. He didn't pressure us, was very patient, and let us know whenever something new came on the market that was close to what we were looking for. We ended using him as our agent, and we did find a place a few months later.
