Hi..I agree that your buyer's agent does this for you so if you have one you need to ask if they didn't offer. If you are on your own, which I don't recommend, you could only use public records for recent sales and actives on real estate websites. Do not go by the recommended sale price on those sites as usually not accurate. They estimate only from public record info so if someone has done renovations or has outstanding or very poor conditions and yard it is not taken into account. Id be glad to help answer any other questions you may have if I can.
