If you are comparing sold prices of 2013 to sold prices of 2014, then you do know what is happening.

Or, "Where are the 'real' buys in Tyngsboro, Ma today?"
In either case, picking up the phone and calling a local REALTOR will be a great first step in interpreting the reliable data a professional has available.
They are expected to go up another 2.5% this year.
I've noticed a larger increase in condo prices as well. Hopefully this is a sign that the market is bouncing back. Yes, it is not great for first-time buyers but for those with existing mortgages with property values that have tanked in the past, this is great news.
