Location, location would be central square, harvard square, kendall square, and porter square. These are great areas to buy (invest) and live as a professional couple. Lot's of restaurants, night life and access to public transportation. Great demographics because of highly regarded universities. Another interesting area of cambridge to consider is East Cambridge - up and coming, near everything.

Here is everything on the market in Cambridge (you can see every place on a map and choose that way as well):

Thank you, Marie for the maps. I was really looking for information about each neighbourhood, such as demographics. I would also appreciate any input on preferences for professional couple. In other words, i think I am looking for location, location, location! lol.

Jackie,

There are 13 neighborhoods that make up Cambridge, MA. The best reference I can provide is to go to this website:
http://www.cambridgema.gov/GIS/MapAtlasList.cfm

It provides a neighborhood index map and shows which neighborhoods border what other towns.

Thanks,
Marie
