Anecdata: I signed the contract yesterday for a small Somerville single-family, near the Cambridge line, for just over $700k. I'm expecting to put $200k+ into it. If a developer got their hands on it, they would expand the square footage to the maximum possible extent, put in the trendiest appliances and finishes, and flip it for > $1m. That seems to be the economically rational thing for them to do in this market. But I lock in a 20-25 minute bike ride (or 50-minute walk + public transit ride in winter) to work in the Seaport. I saw I-93 at rush hour once, and I shudder at the memory. At least part of my reasoning was, "What if Amazon does choose Boston? Do I move my family into a second or third floor condo with no yard at all?"
