You're staring at a six-month lease remainder and a job offer three states away. It’s a classic panic moment. You don’t want to pay double rent, but you also don't want to get sued by your landlord for breaking a contract. This is exactly where subletting an apartment enters the chat.
It sounds simple. You find someone, they pay you, you pay the landlord. Easy, right? Honestly, it’s usually a bit messier than that. Subletting is essentially a real estate "Inception" move where you become a "tenant-landlord" to a "subtenant." You are still the one on the hook if the new person decides to have a heavy metal band practice at 3:00 AM or, worse, stops paying rent entirely.
The Anatomy of Subletting an Apartment
Basically, subletting happens when a tenant—that’s you—rents out their living space to a third party for a portion of the existing lease term. You aren't walking away from your lease. You’re just layering another person on top of it.
There is a massive difference between a sublease and an assignment. People mix these up constantly. In an assignment, you hand over the keys and the legal responsibility to someone else and walk away forever. In a sublease, you’re still the middleman. If the subtenant burns the kitchen down, the landlord is coming for your security deposit first. According to legal resources like Nolo, the original tenant remains "privy of contract" with the landlord unless a specific release is signed.
Think of it like this: your landlord is the bank, you are the credit card holder, and your subtenant is a friend you gave an authorized user card to. If they go on a shopping spree, the bank still expects you to pay the bill.
Why Your Lease Agreement is the Final Boss
Before you even post an ad on Facebook Marketplace or Craigslist, you have to read your lease. Seriously. Most modern leases in cities like New York, Chicago, or San Francisco have a specific clause about "Subletting and Assignment."
Often, it says something like "Tenant shall not sublet the premises without the prior written consent of the Landlord." Some people take this to mean "no." In reality, it usually means "ask first." In some states, like New York, Real Property Law Section 226-b actually prevents landlords from "unreasonably" withholding consent if you live in a building with four or more units. They can’t just say no because they don’t feel like it. They need a legitimate reason, like the subtenant having a terrible credit score or a history of evictions.

If you skip this step and do an "under the table" sublet, you are playing with fire. If the landlord finds out, they can evict you and the subtenant. Now you have an eviction on your record, which makes renting your next place almost impossible.
The Money Part: Security Deposits and Rent
How do you handle the cash?
It’s tempting to just have the subtenant Venmo the landlord directly. Don't do that. It gets confusing for the landlord's accounting, and you lose track of whether the rent was actually paid. The cleanest way is for the subtenant to pay you, and then you pay the landlord. It keeps the paper trail clear.
Then there’s the deposit. Never, ever let someone move in without a security deposit. Usually, one month's rent is the standard. If they break the window, you’ll need that money to fix it before you move back in or hand the keys back to the landlord at the end of the year.
A Quick Reality Check on Pricing
You might not get full price. If you’re trying to move in the middle of winter or in a slow market, you might have to "subsidize" the rent. If your rent is $2,000, you might only find someone willing to pay $1,800. You’ll have to eat that $200 difference every month. It’s better than losing $2,000, but it’s a bitter pill to swallow.
Finding a Subtenant Who Isn't a Nightmare
Finding someone to take over your space is a job. You are now a leasing agent.
- Take Real Photos. Put away the laundry. Open the blinds. Use a wide-angle lens if you have one on your phone.
- Vet Them Hard. Ask for a LinkedIn profile. Ask for a pay stub. It feels invasive, but remember, your credit score is the one on the line here.
- The "Vibe" Check. Talk to them. If they seem flaky via text, they will be flaky with rent.
I’ve seen people use services like Leasebreak or even Flip (which was acquired by Zillow) to find more "vetted" candidates, but many still rely on local neighborhood groups. Just be careful. Scams are everywhere. If someone offers to send you a cashier's check for more than the rent and asks you to wire back the difference, they are scamming you. Period.
The Legal Paperwork You Actually Need
Do not do this on a handshake. You need a written sublease agreement. It doesn't have to be fifty pages of legalese, but it should cover the basics:
- Start and end dates.
- The exact rent amount and due date.
- Who pays for utilities (don't forget the Wi-Fi!).
- The "What Ifs"—what if they want to move out early? What if they have a pet?
You can find templates on sites like Rocket Lawyer or LawDepot. Just make sure it mentions that the subtenant is bound by all the terms of your original master lease. If your master lease says "no smoking," your sublease needs to say "no smoking."

Insurance: The Forgotten Step
Most renters insurance policies do not automatically cover a subtenant. If your subtenant leaves the bathtub running and floods the apartment below, your insurance company might deny the claim because you weren't the one living there.
Tell your insurance agent what’s happening. Your subtenant should also get their own "renter's insurance for subletters" policy. It’s cheap—usually $15 a month—and it saves everyone from a massive headache if a pipe bursts or a laptop gets stolen.
What Happens if it Goes South?
Let's talk about the worst-case scenario. Your subtenant stops paying and refuses to leave.
Because you are technically their landlord, you might have to be the one to start eviction proceedings. This is the "nuance" people miss when subletting an apartment. You can't just change the locks; that's an illegal lockout in almost every jurisdiction. You have to follow the legal process, which can take months.
This is why the "Landlord Consent" part is so vital. If the landlord approved the subtenant, they might take over the legal heavy lifting if things go wrong. If you did it behind their back, you're on your own in housing court.
Moving Out and Moving In
Before the subtenant moves in, do a walkthrough. Take a video of everything. Every scratch on the floor, every hole in the wall. Send a copy to the subtenant and keep one for yourself.
When they move out, do the same thing. If there is new damage, you deduct it from their security deposit. If you don't have that "before" video, it's your word against theirs, and you'll likely lose that fight in small claims court.
Actionable Steps for a Successful Sublet
If you’re ready to move forward, don't just wing it. Follow this sequence to protect your wallet and your reputation.
- Audit Your Lease: Look for the "Consent" clause immediately. If it's not there, check your local state laws regarding tenant rights.
- Get Written Permission: Send an email or a certified letter to your landlord. Include the reason you're leaving and the dates.
- Create a "Home Manual": Write down how to jiggle the toilet handle, where the trash goes, and the Wi-Fi password. A happy subtenant is a paying subtenant.
- Draft the Sublease: Use a formal document. Include a clause that requires the subtenant to abide by the building's "House Rules."
- Collect the First Month + Deposit Upfront: Do not hand over the keys until the funds have cleared your bank account. No exceptions.
- Notify Your Utility Companies: Decide if you're keeping the power in your name or if they need to switch it over. Keeping it in your name is safer for ensuring the heat stays on, but you need to be diligent about billing them back.
Subletting is a massive tool for flexibility in a world where 12-month commitments are hard to keep. As long as you treat it like a business transaction rather than a favor for a stranger, you'll usually come out the other side just fine.
