Mary,

We agree, try http://www.zillow.com. Their records are generally accurate however, be very careful believing their Zestimates. They have been "off the mark" in the past.

Try zillow.com. Type in the address of the home you are interested in. It usually gives a sales history..
It's a great site. Another good site is propertyshark.com. You're allowed to view, I believe, reports on as many as 5 different homes for free. Good luck to you.

Hi Mary:
I'm not aware of a "free" online service, but you can always contact the County offices or you can call our office, as well. If it sold through our MLS, we have almost instant access after it closes to the sold price and any concessions, if applicable. Let me know if I can be of any assistance - you can always reach me on my cell at 518-578-0055.
Thanks
