CMS Partners LLC is a Cambridge, Massachusetts real estate development, construction and property management firm founded in 1994, managing a portfolio of small and medium-sized multi-family and mixed-use properties across the Greater Boston area. The company holds an active Massachusetts Home Improvement Contractor license through the State License Registry. Reviews of its general-contracting renovation work, from Angi clients between 2004 and 2007, described a responsive, well-managed process; separate, more recent reviews from residential tenants in its own buildings describe issues with responsiveness, heating and lease terms.
“The short version: the owner, who's initials make up CMS, is an asshole, and acts like slum lord. The management team (tenant liason, and maintenance team) are great.”
“Anyone rented from them before? Experiences? Couldn’t find much online besides google reviews”
Poorly built apartments, non responsive to certain issues, increased my rent to an outrageous amount. They do help with some problems but in general I wouldn’t recommend. Terrible with heating issues, I constantly feel like I’m baking inside my apartment.
These apartments are so old, the landlord won't update anything, the stove and fridge are really old and small, window sills crack down, doors won't close completely, you'll always listen to the steps from neighbors on top of you, we even listened to our neighbor snoring. Anyways NO RECOMMENDED AT ALL.
We've rented from CMS for the past 3+ years and have had a great experience renting from them. They are very responsive whenever we call or email with any type of maintenance request, always sending someone over in a timely manner and fixing and replacing anything necessary.
I loved my time living in these apartments! The managers and maintenance team are very quick to respond and kind. They were very helpful with any situation that came up.
Had to move to take care of a disabled sibling. Gave CMS partners 2 months notice and offered to find a replacement. They refused and told us we’d have to pay 3 months of rent as a fee to break the lease. During this 2 month period they were showing our apartment to new tenants and they had a replacement move in about 1-2 weeks after we lived out. The workers were good people, but the management felt a bit heartless.
