Subletting your room for the summer

A sublet is a proration across months, plus a reminder that the lease still names you. Get both right before you hand over a key.

The numbers, step by step

You pay $980 a month for your room and sublet it from June 1 to August 15. June and July are full months; August is 15 of 31 nights. The subtenant pays you for those nights and you keep paying your share into the household as usual.

  1. 2026-06: 30 of 30 nights → $980.00.
  2. 2026-07: 31 of 31 nights → $980.00.
  3. 2026-08: 15 of 31 nights → $474.19.
  4. Total: $2,434.19.

Keep it running

Turn this into a household: rent posts at the agreed split each month, bills split by days home, and housr works out who owes whom. Roommates join with a link and a name.

Make it a household

When this split is fair, and when it isn’t

Fair when

  • Your roommates know who will be living there and agreed to it, and the landlord’s consent was obtained where the lease or the law requires it.
  • The subtenant pays the same share you do, prorated by nights; you aren’t profiting from your roommates’ space.
  • Utilities for the summer follow the people actually living there: the subtenant takes your place in the days-home split.

Not so fair when

  • In New York, the Attorney General’s guide notes that if the landlord consents to the sublet, “the tenant remains liable to the landlord for the obligations of the lease, including all future rent.” Your roommates are relying on you, not the subtenant.
  • Charging the subtenant more than your share can breach the lease or local rules, and it makes your roommates uneasy about the whole arrangement.
  • Not telling the landlord where the lease requires consent can put the whole household at risk.

This is general information about splitting costs between yourselves, not legal advice. Your lease and your state’s law decide what you owe the landlord.

Split rent

A new roommate moves in mid-month

Their first month is a proration; every month after is the normal split. Keep the two separate and nobody pays for nights they weren’t there.

Open the example Split rent

A roommate is leaving mid-lease. What do they owe, or get back?

Three separate questions get tangled when someone leaves: this month’s rent, their share of the deposit, and the last bills. Answer them one by one and net them into a single payment.

One roommate pays the landlord. Who sends them what?

Many landlords take one payment. Whoever sends it is fronting money for everyone, so make the amounts exact and the record shared.
