Your buyer broker can answer this question for you easily. If you're not working with one you should be. You can also look up the property in the tax rolls and see what it last sold for.
Now the real question is why it matters. I've been selling real estate full time for over twenty years, nearly every buyer asks this and it's public knowledge so it's easy to answer, but it means absolutely nothing. Market price isn't set by what someone paid in the past, it's set by what a ready willing, able and hopefully sane buyer will pay today. When you buy a home and go to sell it several years in the future, it won't matter what you paid. If the market has gone down you'll sell it for what the market is bearing. If the market has gone up by 100% I assure you you will never tell your Broker, "I couldn't possibly profit that much, I only paid $$$, you can sell it for less" My point being what someone paid in the past has no relationship to what the market is bearing today, sometimes it's up, sometimes it's down. Current sales of similar homes in the neighborhood are a much better indicator of a fair price for the home.
Please do your self a big favor and work with an experienced Buyer Broker. I've attached a link on how to find one in you area.
Best of Luck to you.
