(score 1 – 100) — 69. This Registry of Deeds is for Northern Middlesex County. Middlesex County is separated into two different locations. There is a Southern County location in Cambridge, Ma. This is one of the few registries that is still in it’s original courthouse. What does that mean you ask… well, it’s dank, a little smelly and it gets really hot in the summer due to no central air. If you are buying, selling or getting your mortgage refinanced in the towns of Billerica, Carlisle, Chelmsford Dracut, Dunstable, Lowell, Tewksbury, Tyngsborough, Westford, Wilmington you’re probably have to come here to sign some documents. You can park in the street just beware that the area is a little sketchy and don’t leave anything exposed in your car seats(ie gps, handbag, etc.). There are allot of smash and grabs in this area.
