How to Sublet Your Apartment and Find a Subletter Without Losing Your Deposit

Expert Guide • 8 min read • Updated September 2026

You are eight months into a twelve-month lease and you need to leave. Subletting looks like the obvious answer, and it often is — but done carelessly it leaves you paying rent for a place you do not live in, or losing a deposit you were counting on.

Here is the order that actually works: get permission first, screen properly, document everything, and keep your name clean for the next landlord.

Step 1: Read Your Lease Before You Advertise Anything

Almost every lease says something about subletting, and it will be one of three things:

  • Permitted with written consent. The most common. You can sublet, but the landlord must approve the person first.
  • Prohibited outright. Some leases forbid it entirely. Subletting anyway usually counts as a lease breach.
  • Silent. Rare, and not a green light. Ask in writing before assuming.

Ask your landlord in writing, and keep the reply. A verbal yes is worth nothing if the arrangement goes wrong six weeks later.

Subletting without the permission your lease requires can put your tenancy and your deposit at risk, and it follows you — a landlord reference is the thing you will need for your next application. Always get consent in writing first.

Step 2: Understand What You Stay Responsible For

This is the part most people get wrong. In a normal sublet, you remain the tenant. The subletter pays you; you still pay the landlord.

Which means, unless your landlord agrees otherwise in writing:

  • If the subletter does not pay, you still owe the rent
  • If the subletter damages something, it comes out of your deposit
  • If the subletter breaks a building rule, it is your tenancy that is in breach

The alternative is a lease assignment or a lease transfer, where the new person takes over the lease entirely and you walk away clean. Assignment is better for you and harder to get agreed. Ask for it first — the worst answer is no, and then you sublet instead.

Ask this exact question: “Would you consider assigning the lease to an approved replacement tenant, rather than a sublet?” Many landlords prefer it too — they get a tenant they screened directly, with no middle layer.

Step 3: Where to Find a Sublet Tenant

In rough order of how well they work:

  • People you already know. Friends of friends, colleagues, coursemates. Someone with a mutual connection is easier to trust and easier to chase.
  • Your own network, publicly. A clear post with photos, the exact dates, the exact rent and the exact deposit. Vague posts get time-wasters.
  • Employer or university housing boards. Especially strong if you are near a campus, a hospital or a large employer — people relocating for work or study need short terms and have verifiable income.
  • Local community groups. Neighborhood and city-specific groups outperform national sites for short lets.
  • Sublet listing sites. Wider reach, but far more time-wasters and more scam risk. Use them last, not first.
  • Ask your landlord. They sometimes have a waiting list already, and a tenant they sourced is one they have already approved.

Time it right: start looking six to eight weeks before you need to leave. Sublets move fastest at the start of a month and around academic terms.

Step 4: Screen Them Like a Landlord Would

You are taking on a landlord’s risk, so do a landlord’s checks. At minimum:

  • Photo ID and confirmation of who they are
  • Proof of income — pay stubs or an employment letter, ideally showing around three times the rent
  • A reference from their current or previous landlord
  • A conversation, in person or on video. Ask why they need a short term and what their dates are
  • Credit and background screening if the amount at stake justifies it — our guide on tenant screening explains what these checks cover

Then pass the file to your landlord for approval. Presenting a screened candidate with documents attached gets a yes far more often than asking whether subletting is allowed in principle.

Never accept a deposit or first rent before you have met the person and verified their identity and income. Overpayment scams — where someone sends more than asked and requests the difference back — target sublets specifically.

Step 5: Put It in Writing

Whatever you agree, write it down and have both parties sign. A sublet agreement should state:

  • Full names of both parties and the property address
  • The exact start and end dates
  • The rent, when it is due, and how it is paid
  • The deposit amount, who holds it, and what it covers
  • Which bills the subletter is responsible for
  • What happens if they leave early, or stay past the end date
  • A statement that the original lease terms apply to them too, with a copy attached
  • Confirmation that the landlord has consented in writing

Then do the handover properly: photograph every room before they move in, and again when they leave. Those two sets of photos are what stand between you and a damage charge on your own deposit. The move-in / move-out checklist template works for a sublet handover exactly as it does for a tenancy.

Keep the paper trail in one place. If your landlord uses My Rental Spot, the lease, the condition report and every message sit in your tenant portal, timestamped. When the sublet ends and someone questions a mark on a wall, the record already exists.

When Subletting Is the Wrong Answer

Three situations where you should do something else:

  • Your lease prohibits it. Ask about assignment or early termination instead. Many landlords will agree to release you if you find a replacement they approve.
  • You have less than two months left. The admin rarely justifies the saving. Negotiating an early exit is usually simpler.
  • You cannot screen properly. If you are moving abroad next week and cannot meet anyone, you are accepting a risk you cannot manage. Talk to the landlord instead.

If you are leaving for good rather than temporarily, the sequence in our move-out checklist applies — notice, cleaning, documentation, deposit.

Subletting Questions

What is the difference between subletting and assigning a lease?

In a sublet you stay on the lease and remain responsible to the landlord. In an assignment, the new tenant takes over the lease and your responsibility ends. Assignment is cleaner for you but needs the landlord’s agreement.

Can my landlord refuse a subletter?

Generally yes, and many leases require their consent. What counts as a reasonable refusal varies by state and by lease. Present a properly screened candidate — a refusal is much less likely when the file is complete.

Who holds the subletter’s deposit?

Usually you, because your deposit with the landlord stays where it is. Say so explicitly in the written agreement, along with what it covers and when it comes back.

How much should I charge a subletter?

Charging more than your own rent is prohibited in some places and resented almost everywhere. Charging the same is the norm and the easiest to defend.

What if the subletter will not leave?

This is the main reason to have fixed dates in writing and the landlord’s consent on file. If it happens, speak to your landlord immediately — and get advice, because removing an occupant has legal requirements that differ by state.

How long does it take to find a subletter?

Two to six weeks in most markets if the price is right and the listing is specific. Start six to eight weeks out so you are not accepting whoever turns up last.

Keep Your Tenancy Record Clean Through a Sublet

Lease documents, condition reports and every message stored and timestamped — so a sublet does not cost you the reference you need for your next place.
