To answer that question really would require more information as to your wants and needs. Where will you be working and how close to work would you like to be. Would you drive to work or take public transportation. Do you want city or suburban life, or something with a flavor of both. There are many wonderful communities in the metro Boston area, should you not want to be directly in the city. And then there is the price point factor. Not only what you qualify for, but what monthly mortgage payment fits your comfort zone.
My suggestion, in advance to arriving into the area, contact a few agents and have a discussion with them. Perhaps upon you arrival, meet with two or three to see who you would be most comfortable working with and to have represent you in your home purchase.
I welcome you to visit my website, http://www.bobbittelari.com.
You will find valuable information about the home buying process, buyer representaion, financial information, and most importantly at this time for you, the section on Commonwealth Communities.
Best of luck in your search.
