I offer "Market Snapshot" as a free service on my website. If you go there and order one, it will give you the properties that have closed within whatever time frame you request, and it will also update you monthly, if you'd like.
No obligation whatsoever.
Unfortunately, the only reliable source is the local MLS which only Realtors can view. The alternative is to visit your local tax office but the recorded sales get posted months after the actual sale.
Your best option: Find a Realtor to be represent you as a Buyers' agent so they can help.
