More than the national average, but less than historical trends might lead you to believe. Somerville property (especially along the proposed greenline extension) has skyrocketed in value over the past 20 years or so. Unfortunately, y’all have mostly missed the boat on that increase – that property has already been bought by speculators and the price has increased accordingly. The somerville market is “played out” so to speak from an investment standpoint. Still, the Boston-metro area is a very good place to buy. Boston is one of the hottest housing markets in the country and you’ll see a good return. And if you expect to keep it for 5 years, you’ll almost certainly make money on it – values will probably jump a bit when the green line extension goes into service and becomes more tangible for people in 2021 (according to MBTA official schedules) or 2025 (according to MBTA history).
