Yes. The New Hampshire Association of Realtors compiles county by county data on time on the market.
However, I would also point out that while the past couple of years have allowed plenty of time for analysis, there has been a shift in the past 6-8 weeks and now my overly analytical buyers are missing out on good deals. Not sure what you are attempting to discover. There will be some stubborn sellers (a lot of them actually) who came on the market some time ago and were unwilling to price to the market situation. Those sellers need an offer from a buyer to deliver reality. I just closed a sale on a property that was on the market for about four years at roughly half what it was on the market for during 3 of those years. Use the offer and market data on value to find your bargain.
