This is just one of the countless things that a good Realtor does for their clients. Also taking the time to explain and educate them about the market is essential. My job is to educate my clients so they have the information they need to make informed decision. It's your money whether you are buying a house or selling a house. It's my job to ensure that you are making decisions to keep or make as much equity as possible.
Good luck with your search.

Websites that pull info off of the MLS are usually outdated and can not be considered accurate.
You can look at the tax appraisal roles, but those are also often as far up or as far down as any other online method.
You might also look at Zillow....but their margin of error in Texas is also pretty far off.
Those are the free sources and you get what you pay for on free....it should give you a ballpark.
Another source is an appraisal. You might also ask your lender if they have any sort of online system to judge value.
