In short, I suggest that you have your own experienced Broker who is a Realtor as well (rather than an agent/salesperson of unknown characteristics) represent you.
It's free-to-you, and in some cases, you can actually actually receive Cash-Back from some Brokers.
In order to make the best decision, you should have a comprehensive look at & comparison of homes that are ON the market, plus homes that may NOT officially be on the market.
More important, you can evaluate your chosen Broker BEFORE it's time to make an offer, and be sure you're working with someone you know and trust, not some unknown respondent to your on-line question (since any answer you get is only as good as the salesperson giving it, who is necessarily unknown to you when you ask the community as a whole).
