Wakefield is a lovely suburb. It has a great school system, wonderful downtown, the aforementioned Lake Quannapowitt and the Gingerbread Construction company, to name just a few features. The market is as stable as a home buyer can ask for.
A home is also a long-term investment and market risks are inherent with any property in any area. There is nothing about Wakefield right now that suggests that it would be any more of a risk than any other city or town. In fact, Wakefield being a more desirable community now suggests that it will likely continue to be just as, if not more desirable five years from now.
Also, Wakefield's DOM being > 70 days isn't a big concern in this market and is actually lower than many other surrounding areas. Wakefield's DOM tends to hover around that time frame anyway. That's not new and it actually suggests stability. There are many reasons that DOM could be high - from overpricing to overall affordability to agent's being slow to tag their listings to different statuses. But DOM being around 70 days is far from bad.
In short, I think you're good here.
Good luck with your home search and give me a shout if you need help with your financing.
