Yes, someone can cosign for an apartment, and most landlords will accept one — especially when the primary applicant has thin rental history, uneven income, or a credit score below the property’s threshold. The cosigner agrees to stand behind the lease financially, giving the landlord a second person to collect from if rent goes unpaid. Parents are the most common choice, but siblings, other relatives, friends, and even paid guarantor companies can fill the role as long as they meet the landlord’s requirements.
Who Can Serve as a Cosigner
There’s no legal rule limiting cosigners to family. Anyone willing to take on the financial obligation and able to pass the landlord’s screening can qualify. The cosigner doesn’t live in the apartment and has no right to occupy it or make decisions about the tenancy unless they’re also listed as a tenant on the lease.
Location can matter. Some landlords prefer or require a cosigner who lives in the same state as the rental, because collecting from an out-of-state cosigner means navigating different procedural rules for serving legal papers and enforcing judgments. Plenty of landlords accept out-of-state cosigners anyway, particularly in cities with large student or transplant populations. If your cosigner lives elsewhere, ask about the policy before applying.
When no personal cosigner is available, institutional guarantor services can take the role for a fee. More on that below.
What a Cosigner Has to Qualify Financially
Landlords set a higher bar for cosigners than for tenants, because the cosigner has to be able to cover rent on top of their own living expenses. The most widely cited standard in competitive urban markets — especially New York City — is the “80x rule”: annual gross income of at least 80 times the monthly rent. A $2,000 apartment under that rule needs a cosigner earning $160,000 a year. In less competitive markets, landlords may ask for 40 times the monthly rent, or simply three to five times the rent in annual income. Always check the specific property’s standard.
Credit expectations run higher too. Many landlords want a score of 700 or above, though some accept the mid-to-high 600s if income is strong and the credit report shows consistent debt management with no recent collections, bankruptcies, or judgments.
Retired or Non-Working Cosigners
Retirees without a paycheck can still qualify if they can show the resources to cover rent. Some landlords accept liquid assets — savings, investment accounts, retirement distributions — in place of employment income, with a common benchmark of three to six months of rent held in accessible accounts. The cosigner provides recent bank or brokerage statements as proof. Not every landlord accepts asset-based qualification, so confirm before a retired family member applies.
Cosigner vs. Guarantor
Landlords use these words interchangeably sometimes, but in many leases the two roles are distinct. A cosigner is usually a party to the lease itself and shares the tenant’s full obligations from day one. A guarantor signs a separate agreement and is only called on if the tenant defaults.
Before signing, read the document. If it’s titled “Guaranty of Lease” and is separate from the main lease, you’re a guarantor. If you’re signing the lease itself alongside the tenant, you’re a cosigner. The practical difference is when liability starts, so it’s worth knowing.
What the Cosigner Agrees To
A cosigner agreement is a binding financial commitment. Under joint and several liability, the cosigner can be pursued for the full unpaid balance, not a share of it. The landlord doesn’t have to exhaust remedies against the tenant first unless the agreement specifically requires that.
Liability generally reaches beyond rent. It can include damage beyond normal wear and tear, unpaid utilities covered under the lease, early termination fees, and legal costs tied to a breach. If the landlord gets a court judgment, the cosigner’s wages can be garnished and the unpaid balance reported to credit bureaus.
How Long the Obligation Lasts
A cosigner’s obligations run through the full initial lease term and often continue through renewals. If the lease rolls over to month-to-month after the initial term, the cosigner’s liability frequently continues unless the agreement says otherwise or the landlord signs a written release. A one-year commitment can quietly become open-ended, so read the renewal and extension language closely before signing.
No Right to Occupy or Control the Lease
A cosigner who isn’t named as a tenant can’t live in the apartment, enter the unit, or make decisions about the tenancy. They also can’t terminate the lease or evict the tenant — only the landlord can do that. The cosigner carries full financial risk with no control over how the tenant treats the property or whether rent gets paid on time.
How Cosigning Affects the Cosigner’s Own Finances
Even in a lease that goes smoothly, cosigning can affect the cosigner’s borrowing power.
Most residential leases don’t show up as monthly tradelines on a credit report unless the landlord uses a rent-reporting service. The application itself does generate a hard inquiry, which can cause a small temporary dip. The bigger risk comes if the tenant misses payments: unpaid balances sent to collections create a collection entry on the cosigner’s report that can stay for up to seven years from the date of the original delinquency.
Mortgage lenders and other creditors typically count the full cosigned rent payment in the cosigner’s debt-to-income ratio, even when the tenant is the one actually paying. That can shrink the loan amount the cosigner qualifies for, increase required down payments, or lead to a denial. Anyone planning to buy a home or take on other debt soon should think carefully before cosigning.
The Application and Screening
The cosigner goes through screening much like the tenant. Expect to provide:
- Government-issued photo ID, such as a driver’s license or passport.
- Proof of income, usually 30 to 60 days of pay stubs, W-2s, or tax returns. Self-employed cosigners typically provide a recent Schedule C or full tax return.
- An employment verification letter on company letterhead confirming title, tenure, and salary.
- Bank statements, especially for retirees or anyone qualifying on assets.
The landlord supplies an application and uses the cosigner’s Social Security number to pull a credit report. An application fee covers the screening cost. The national average sits near $50, but fees vary by market and some states cap them — New York, for example, limits application fees to $20, while other states tie the cap to the landlord’s actual screening costs. Screening usually takes two to three business days.
Federal law gives cosigners a specific protection in this process. Under the Fair Credit Reporting Act, requiring a cosigner is itself an “adverse action,” because the landlord has decided the tenant couldn’t qualify alone based on information in a consumer report. When that happens, the landlord must send a written notice identifying the credit reporting agency used, stating that the agency didn’t make the rental decision, and explaining the applicant’s right to dispute inaccurate information and get a free copy of their report within 60 days.1Consumer Financial Protection Bureau.

Removing a Cosigner Later
Taking a cosigner off a lease before it ends requires the landlord’s agreement. Neither the tenant nor the cosigner can do it unilaterally. The usual path is a written request for a “novation” or “guarantor release.” Build the case with 6 to 12 months of on-time rent payments, current pay stubs showing income that meets the property’s threshold, recent bank statements, and an updated credit report.
Some cosigner agreements include built-in release conditions, such as automatic release after 12 months of on-time payments. Others only consider removal at renewal. If the landlord agrees, get the release in writing with a specific effective date. Until that signed document exists, the cosigner remains liable no matter what anyone has said verbally.
If the landlord refuses, the obligation generally ends only when the lease expires without renewal or when the tenant signs a new lease without the cosigner. Offering a replacement cosigner or a larger security deposit sometimes persuades a reluctant landlord.
If No One Can Cosign
Professional guarantor companies act as institutional cosigners for a one-time fee, typically 70 to 110 percent of one month’s rent. The exact cost depends on the tenant’s credit profile, income stability, and citizenship status; non-U.S. citizens generally pay toward the higher end.2Insurent. Rental Guarantor Service – Renter Information A few things to confirm before paying:
- Not every property management company accepts institutional guarantors. Check with the landlord first.
- The fee is non-refundable and doesn’t apply toward rent.
- If the guarantor company pays the landlord after a missed payment, it will come after you to recover that amount, often with added fees or interest.
Other ways to qualify without a cosigner include offering a larger security deposit (within state caps), prepaying several months of rent, adding a roommate whose income and credit meet the property’s standards, or applying to a less expensive unit where your own income clears the threshold.
