New York rental scams and unauthorized sublets: what to check before you pay

There are two different ways a New York rental goes wrong for an arriving researcher, and they need different checks. The first is an outright scam: the apartment does not exist, or the person advertising it has no connection to it. The second is subtler and far more common — the apartment is real, the person is real, and they were not allowed to rent it to you.

Part one: the listing that is not real

The Federal Trade Commission documents two mechanics, and both show up constantly in academic housing groups.

Hijacked listings. Someone copies the photographs, the description or the virtual tour from a genuine listing, swaps in their own contact details, and posts it somewhere else. Everything looks right because everything except the phone number is real.

Invented listings. A price noticeably below the market, unusually good amenities, and — when you ask to see it — an owner who is out of the country, or has another reason not to show you the place, and who needs a decision quickly.

The checks that catch both:

• Reverse image search the photographs. It takes a minute and catches hijacked listings outright.
• Treat pressure as the signal, not the price. The FTC's advice is blunt: if anyone pressures you to decide quickly, walk away. Legitimate landlords lose apartments to slow tenants all the time and survive it.
• Never pay by wire transfer, gift card or cryptocurrency. The FTC states flatly that a demand to pay only by those methods is a scam, because those payments are the same as sending cash. New York's Attorney General names Western Union, MoneyGram, Zelle, CashApp and Venmo specifically, and advises booking only with a credit or debit card and only through the listing site.
• Do not hand over your social security number before you have agreed to rent. The FTC notes that until you have agreed, a landlord does not need it, and that most landlords pull your credit themselves rather than telling you to get it for them.
• Do not sign, pay a deposit or complete a background check before you have had a chance to inspect the place. That is New York's Department of State's own advice.
• Insist on a live video walkthrough if you cannot visit. Not a recorded tour — a live call where you can ask them to point the camera at the window, the boiler, the street sign. A person who cannot do that on any of three attempts is telling you something.
• Check the address exists and matches. If a booking claims to be a registered short-term rental, New York City publishes its registration dataset. And if you booked a listing in that dataset but were sent to a different address, the city asks you to file a complaint.

Part two: the sublet nobody authorised

This is the one that actually costs academics money in New York, because so many arrive into a sublet and almost nobody asks the question.

The rule. In a building with four or more residential units, state law gives a tenant the right to sublet with the landlord's advance consent, which may not be unreasonably withheld. But it is a formal procedure — the state's own subletting fact sheet sets out what a written request must contain and the deadlines on both sides. If your prime tenant never made that request, your position is weak: you have paid money to someone who was not entitled to let you in, and the landlord's argument is with them, not you.

Rent-stabilised apartments have extra rules, and they are routinely broken. A rent-stabilised tenant must keep the apartment as their primary residence and intend to return, and may not sublet for more than two years out of the four years before the sublease ends. If they sublet furnished, they may charge no more than a ten per cent increase over the lawful rent for the furniture — which is exactly the rule being broken when a "furnished academic sublet" is priced at double what the tenant pays. If a subtenant is overcharged and the state housing agency agrees, the prime tenant has to refund three times the overcharge. And where the prime tenant never really lived there at all — an "illusory" sublet designed to get around rent stabilisation — the subtenant can challenge it and may end up recognised as the actual tenant at the lawful rent.

Assignment is not sublet. Taking over someone's lease outright is an assignment, and a landlord may withhold consent for that unconditionally.

If you are joining a household rather than signing anything, state law lets a sole leaseholder have one roommate plus that roommate's dependent children, and lease clauses forbidding it are void. In a rent-stabilised apartment you may only be charged a proportionate share of the legal rent. But you have no independent right to stay: if the leaseholder leaves, so do you.

The three questions to ask a prime tenant

1. May I see your lease? You are checking that they hold it, and what it says about subletting. 2. May I see the landlord's written consent to this sublet? "The landlord is fine with it" is not consent. If they cannot produce it, ask when they made the request. 3. Is the apartment rent-stabilised, and what is the legal rent? If it is and they are charging you far more than the legal rent plus a modest furniture increase, you are being overcharged and there is a remedy.

Asking those three questions makes some people uncomfortable. That discomfort is information.

Things specific to arriving academics

• An institutional email address proves nothing about a property. Someone writing from a university domain has an account at that university. It does not mean they own, rent or control the apartment they are describing. Verify the housing, separately, every time.
• A university listing board is not a vetted listing board. Columbia states in its own disclaimer that it does not screen owners or tenants, does not inspect apartments, and does not verify listing descriptions. Weill Cornell's own short-term housing page carries a warning about sublet scams. The affiliate-only sections are better because the poster is identifiable, not because anyone checked the flat.
• Departmental mailing lists and alumni groups are the best channel and still not a guarantee. They are excellent at surfacing genuine sublets from people with a reputation to protect. They are still just people on the internet who can be impersonated.
• Below-market is the bait, not the bargain. The FTC's advice is to consider the price: if the rent is far cheaper than most rents in the area, it may be a sign of a scam. In New York, where the market is brutally efficient, a genuinely cheap furnished room offered to a stranger abroad is unusual enough to deserve suspicion.
• You will probably leave before a dispute resolves. That asymmetry is why the paperwork matters more for you than for a local: a written agreement, the pre-occupancy walkthrough the law entitles you to with existing damage recorded and signed, photographs on the day you move in, and a traceable payment method.

If something has already gone wrong

Report it — the FTC takes reports at its fraud reporting site, and the New York Attorney General's office handles complaints against landlords and agents. If a rent-stabilised sublet overcharge is involved, the state housing agency has a complaint process with a real remedy. And if the listing involved a short-term rental registration in New York City, the city asks guests to file complaints where a booking did not match the registered listing.

None of that gets your money back quickly. All of it is worth doing anyway, because these operations run on the fact that transient visitors rarely report.
