The 40x Rent Rule and Guarantors: How NYC Landlords Screen Tenants

Look up any NYC building’s records →

Almost every NYC rental application runs into the same two walls: the 40x income rule and the guarantor requirement. Here's how they actually work, what's legal, and what to do if you don't qualify.

What the 40x Rule Is

The 40x rule is the standard income test most NYC landlords apply: your gross annual income should be at least 40 times the monthly rent. For a $3,000/month apartment, that means $120,000 a year. For a $2,000 apartment, $80,000.

Important context: the 40x rule is not a law. It's a market convention — a landlord screening practice, not a legal requirement. Landlords can apply stricter or looser standards. Some accept 38x or 35x; large management companies often hold firmly to 40x.

For roommates, most landlords combine incomes — two people splitting a $3,000 apartment need a combined $120,000, though some buildings apply stricter math to combined applications.

What IS Legally Regulated

While income standards are up to the landlord, several screening practices are regulated:

• Application fees are banned. Under New York's 2019 rent law (RPL §238-a), a landlord may not charge an application fee. The only permitted charge is for a credit or background check — capped at the actual cost or $20, whichever is less — and even that must be waived if you provide a copy of a credit or background check conducted within the past 30 days. A landlord demanding a $100 "application fee" is violating state law.
• Source-of-income discrimination is illegal. Landlords cannot reject you for using housing vouchers (Section 8, CityFHEPS, etc.). For voucher holders, the 40x test legally cannot be applied to the voucher portion of rent.
• No fees beyond the legal limits at lease signing: one month security deposit maximum, first month's rent, and at most a credit/background-check fee (actual cost or $20, whichever is less).

When You Need a Guarantor

If you don't meet the income threshold — common for students, freelancers, newcomers without U.S. credit history, or anyone whose income is solid but below 40x — landlords typically ask for a guarantor: someone who signs the lease promising to cover your rent if you don't pay.

The standard guarantor ask is steep: 80x the monthly rent in annual income — $240,000 for a $3,000 apartment. Many landlords also historically required guarantors to live in New York or the tri-state area, though this has loosened at many buildings.

A guarantor is fully on the hook: if you miss rent, the landlord can pursue them directly. It's a serious legal commitment for whoever signs.

If You Don't Have a Guarantor

Institutional guarantor services. Companies like Insurent and TheGuarantors act as your guarantor for a fee — typically a percentage of one month's to a full month's rent, depending on your profile. Many large buildings accept them; smaller landlords vary. If a listing says "guarantors accepted," ask whether institutional guarantors qualify.

Offer more documentation, not more money. Bank statements showing savings (some landlords accept liquid assets in lieu of income — a common informal standard is savings covering 12+ months of rent), an employer letter, or a strong rental payment history can move smaller landlords.

Prepaying rent is restricted. Under the 2019 law, landlords generally cannot demand more than one month's rent plus one month's deposit upfront — offering six months prepaid is not a legal workaround at regulated buildings, and landlords who accept it at market-rate buildings are in gray territory. Be cautious of anyone demanding it.

Before You Apply

A landlord screens you — screen them back. Run the building through Weverit before you submit an application: open violations, complaint history, and ownership records tell you whether the building deserves your application and your guarantor's signature.

Frequently Asked Questions

Is the 40x rent rule a law in NYC? No. It's a landlord screening convention, not a legal requirement. Landlords set their own income standards — but application fees are banned (only a credit/background-check fee, capped at the actual cost or $20, is allowed) and source-of-income discrimination is illegal.

How much does a guarantor need to make in NYC? The standard ask is 80x the monthly rent in annual income — $240,000 for a $3,000/month apartment. Requirements vary by landlord.

What if I can't find a guarantor? Institutional guarantor services (Insurent, TheGuarantors) act as your guarantor for a fee and are accepted at many buildings. Liquid savings or strong documentation can also work with smaller landlords.

Can a landlord charge me $100 for a rental application? No. New York banned application fees entirely. A landlord may only charge for a credit or background check, capped at the actual cost or $20, whichever is less — and must waive even that if you provide a recent (within 30 days) check. A $100 "application fee" is illegal.
