How to Split Rent in Boston, MA
Boston runs on an academic calendar, and the rental market bends to it. With MIT, Harvard, BU, Northeastern, and more packed into the metro, September 1 is by far the most common lease-start date, and roommates who miss that window face a much thinner market. The two-bedroom median sits near $2,711, with a one-bedroom around $2,288.
Two Boston-specific costs catch roommates off guard: broker fees and deposit interest. Both change the upfront and ongoing math, so they belong in the conversation before you split anything, not after the first surprise charge lands.

The September 1 crunch and the split
Because so many leases turn over on September 1, Boston roommates often commit to a place fast to avoid getting shut out. That urgency is precisely when people skip the split conversation, so lock the numbers down even while you're hurrying to sign.
An even split of a $2,711 two-bedroom is roughly $1,355 each, and three roommates land near $903 a person. If the rooms differ, as many older Boston units do, weight the split toward the better room rather than defaulting to half under deadline pressure.
Broker fees, who pays now
Many Boston apartments are leased through brokers, and historically tenants paid the broker fee, often a full month's rent on top of the deposit and first month. A 2024 regulation shifts that obligation to landlords in many cases, which can change your move-in budget meaningfully.
Clarify upfront who's paying the broker fee and split it the same way you split rent if it falls on the tenants. A surprise month's-rent fee discovered at signing is a bad way to start a roommate budget, so confirm it before you commit.
Massachusetts deposit law, with interest
Massachusetts General Laws Chapter 186 section 15B caps the deposit at one month's rent and requires the balance back within 30 days of move-out. The state also requires landlords to pay annual interest on deposits, an unusual protection worth knowing.
Record each roommate's deposit share at move-in. Between the one-month cap and the interest requirement, Boston deposits come with a clear paper trail by design, and your internal split should match it so the refund and interest divide without argument.
