Hi Ron and Ann. Thanks for starting this thread - we have been waiting for conversations about New Hampshire, which aren't as plentiful here as I would have imagined! We have a vacation property on Baxter Lake in Farmington, which is right over the town line from Rochester. So far, so good with that one.
We have been looking at multis in Rochester NH and Dover NH while studying the population trends there. Two weeks ago, we went to Open Houses in both cities, and each property went under agreement two days after each first OH. Dover has a great downtown and plenty of units within a 10-15 minute walk of the Amtrak station.
Portsmouth is very expensive, so people are looking toward Dover to live. As Dover appreciates, we think that Rochester is the next area professionals will look for affordable places to live while remaining within 30-40 minutes of the Seacoast. We have an optimistic eye on downtown Rochester, but are hesitant about the tenant quality of some neighboring streets. But downtown Rochester is only 18 minutes from downtown Dover, both cities have 30,000 residents, and Dover's population has grown 10% since 2000 (whereas Rochester's has grown 5% in that time). We think that Rochester might be next.
