Apartments for Rent With a Cosigner: Requirements, Paperwork and Alternatives

From Listings to Living

The offer letter says $62,000. The one-bedroom you want rents for $2,100 a month, and the leasing agent explains that the building requires annual income of 40 times the monthly rent. That is $84,000. You can afford the apartment. You just cannot prove it the way the building measures it.

Apartments for rent with a cosigner solve that gap. Many landlords will approve an applicant who falls short on income, credit or rental history if a second, financially stronger person signs on and agrees to cover the rent if the tenant does not. The cosigner usually has to clear a higher bar than the one you missed, and the exact bar is set by each property, not by law.

So the practical sequence is simple: find out what the building requires of a cosigner before you apply, line up someone who clearly meets it, and get the terms of that person's obligation in writing.

When to look at apartments for rent with a cosigner

Apartments.com lists the usual reasons a landlord asks for a cosigner: insufficient income, a low credit score, no steady income or employment, no rental history, a record of past evictions, or an apartment with especially strict requirements. In practice that covers a few familiar groups:

  • Students and recent graduates with thin credit and no prior lease.
  • Renters starting a new job, whose offer letter does not yet show a pay history.
  • Self-employed renters whose income is real but uneven on paper.
  • Renters rebuilding after an eviction or a collection account. If that is you, our guide to second chance apartments covers the rest of the application.
  • Renters in high-cost markets where the income multiple outruns ordinary salaries.

Relocating renters often fit two of these at once. Our guide to renting an apartment out of state covers the documents that substitute for local pay stubs.

Cosigner apartment requirements: income, credit and paperwork

Landlords judge a cosigner on the same factors they judge you, with the bar raised. Outside New York City, Apartments.com describes a typical cosigner requirement as income that meets a set multiple of the rent, such as three or four times, along with a strong credit history.

New York City is the outlier most often cited. According to Brick Underground's December 2025 guide, NYC landlords prefer tenants who earn 40 times the monthly rent per year, and personal guarantors are generally required to have a credit score of at least 700 and annual income of 80 times the monthly rent. Those are market conventions, not legal rules, and individual buildings set their own.

The table puts those conventions into dollars. The figures are illustrative arithmetic, not any particular landlord's policy.

ScenarioMonthly rentTenant would needCosigner or guarantor would need
NYC convention (40x tenant, 80x guarantor)$2,500$100,000 a year$200,000 a year
Cosigner at 3x monthly rent$1,600Set by the property$4,800 a month, or $57,600 a year
Cosigner at 4x monthly rent$1,600Set by the property$6,400 a month, or $76,800 a year

An 80x annual standard works out to roughly 6.7 times the monthly rent each month, which is why so many otherwise comfortable parents fail the NYC test.

What credit score does a cosigner need for an apartment?

There is no universal minimum, and the published ranges cluster in the high 600s and up. Experian says good or better credit, a score of 670 or above, is generally preferred for cosigners on an apartment lease. Apartments.com describes cosigner scores as often 680 to 700 or higher, and the NYC guarantor convention sits at 700 or more. Ask the property for its number rather than assuming.

The paperwork your cosigner will be asked for

Zillow's guide lists what landlords typically request from a co-signer: proof of income such as pay stubs, tax returns or employer verification; credit information; identification; and a signed co-signer agreement. Expect the building to run its own credit check on the cosigner as well, so ask in advance whether a separate application fee applies.

How to find an apartment with a cosigner

Listings rarely advertise themselves as apartments for rent with a cosigner, so ask before you apply. A five-minute call or email saves an application fee and, more importantly, saves your cosigner from sending tax returns to a building that will not accept them. Ask:

  • Do you accept personal cosigners or guarantors, and what income multiple and credit score do you require of them?
  • Does the cosigner have to live in this state, or in the same metro area?
  • Do you accept institutional guarantor services, and which ones?
  • Does the cosigner sign the lease itself or a separate guaranty, and does it need to be notarized?
  • Will the cosigner's obligation cover renewals, or end with this lease term?

Apartments that accept cosigners tend to be the ones that will answer those questions in writing. Larger managed buildings usually have a fixed policy; individual landlords often decide case by case. You can browse rentals on Leevli and send the questions before you tour. In New York, where guarantor rules are tightest, the New York neighborhood overview helps you narrow areas before you start the paperwork.

The cosigner lease agreement: what your cosigner actually signs

Depending on the landlord, a cosigner either signs the lease alongside you or signs a separate guaranty agreement or lease addendum. The difference matters legally, and leases often use the words loosely, so the document controls. Our article on cosigner vs guarantor explains how liability and occupancy rights differ between the two roles.

For the search itself, your cosigner needs to read four things before signing:

  1. What is covered. Rent alone, or also late fees, damages, legal fees and utilities billed through the landlord.
  2. Whose conduct is covered. Experian notes that some lease agreements make the cosigner responsible for the actions of all tenants in the apartment, even though the cosigner does not live there. With roommates, that can mean covering someone your cosigner has never met.
  3. How long it lasts. The current term only, or every renewal and extension until the tenancy ends.
  4. How the cosigner gets notified. Whether the landlord must tell the cosigner when rent is late, or can wait until the balance is large.

Shorter commitments are easier to ask for. If you are weighing a fixed term against a month-to-month arrangement, our comparison of lease vs rent shows how the term shapes everyone's exposure.

Institutional guarantor services

If nobody you know qualifies, a company can act as your guarantor for a fee. These services are effectively insurance or surety products: the landlord is protected, you pay the premium, and you remain on the hook if they ever pay the landlord on your behalf. The building has to accept the specific service, so ask first.

Two examples show how the category works:

  • Insurent. Its renter page says U.S. applicants need annual income of 27.5 times the monthly rent, or liquid assets of 50 times the monthly rent, plus decent to good credit. The price is 70 to 90 percent of one month's rent for a one-year guaranty for U.S. applicants, and 98 to 110 percent for non-U.S. applicants. Renters remain subject to legal action for full recovery of anything the insurer pays the landlord. It lists coverage in a set of states and Washington, D.C.
  • TheGuarantors. Its renter FAQ describes its Lease Guarantee as an insurance policy with the landlord as beneficiary, priced on your rent, the coverage the property requires and your financial profile. The premium is non-refundable, and if you default and the company pays, you must repay it.

Run the numbers on a $2,500 apartment: at 70 to 90 percent of a month's rent, a one-year Insurent guaranty for a U.S. applicant would cost $1,750 to $2,250, paid once and not returned. For many renters that beats losing the apartment, though a qualifying relative would have cost nothing.

Other ways to qualify without a cosigner

If no cosigner is available and a guarantor fee is out of reach, apartments for rent with a cosigner are not the only route. Three alternatives are worth checking.

A larger deposit. This used to be the standard workaround, and in several states it no longer works. Brick Underground notes that New York's 2019 rent law changes capped the security deposit at one month's rent. The statute caps any deposit or advance at one month's rent for most residential leases (N.Y. Gen. Oblig. Law § 7-108). California caps security at one month's rent for most landlords, with up to two months allowed for certain small landlords (Cal. Civ. Code § 1950.5). Check your state before offering more.

A co-applicant. A roommate whose income counts toward the total can close the gap, but a co-applicant lives there and shares the lease, which is a different commitment from a cosigner's.

A different apartment. At a 40x standard, every $100 of monthly rent you cut lowers the income you must show by $4,000 a year.

How to ask someone to cosign, and what to put in writing

Asking is easier when you hand the person a plan rather than a favor. Zillow suggests explaining your situation, preparing a budget and talking openly about the worst case before anyone signs.

  1. Show the lease, the rent, the term and your monthly budget with the rent included.
  2. Tell them exactly what the landlord will ask of them, from documents to the credit check.
  3. Explain your plan if you lose income, such as savings set aside or a subletting clause in the lease.
  4. Agree on what happens at renewal: whether they will sign again, or whether you will requalify alone.

Then write down what the two of you agreed: who pays if rent is late, that you will tell them within a set number of days of any problem, that they can view the rent portal or receive copies of notices, and when their commitment ends. A side agreement like this does not bind the landlord, but it protects the relationship. Give your cosigner a full copy of the signed lease and guaranty.

Cosigner apartment pros and cons

ProsCons
For the renterAccess to apartments you could afford but could not qualify for; often no added feeA missed payment damages a personal relationship as well as your record
For the cosignerHelps someone they trust; no ongoing cost if rent is paidFull exposure for rent and possibly damages, sometimes for roommates and renewals too
Compared with a guarantor serviceUsually free to the renterHarder to find someone who meets an 80x or 4x standard

Before you commit, ask people already living in the building how management treated their cosigner, and how fast approval moved, on Ask a Resident.

Questions to ask a current resident

A building's guarantor policy is printed on the application; how management actually handles cosigners, deadlines and late notices is something only its residents have seen.

  • Did you or a roommate use a cosigner or guarantor here, and did management accept them on the first try?
  • How long did approval take once your cosigner submitted documents?
  • Did management insist that the cosigner live in the same state?
  • Has management ever contacted a cosigner directly over a late payment, and how quickly?
  • Did the building accept an institutional guarantor service, and which one?
  • At renewal, did management ask the cosigner to sign again or let the tenant requalify alone?
  • Did any fee or charge show up for the cosigner that the leasing office had not mentioned?

The short version

  • Each property sets its own cosigner requirements, so ask for them before anyone sends documents.
  • Outside New York City, cosigners are commonly asked for income of three or four times the rent and credit in the high 600s or better.
  • In New York City, personal guarantors are generally expected to earn 80 times the monthly rent a year with a score of at least 700.
  • Institutional guarantors charge a non-refundable fee and can collect from you if they ever pay the landlord.
  • Your cosigner should read what the guaranty covers, whose conduct it covers, whether it includes renewals and how notice works.

How Leevli closes the information gap

Listings show the property, but they rarely explain the lived reality around it. On Leevli, a mover can explore the city, review neighborhood and building information, and ask a verified resident the specific questions that remain unanswered. That human layer helps readers know what to investigate before signing a lease, making an offer, or choosing between two addresses.

Frequently asked questions

Ask before you apply. Call or email the leasing office and ask whether it accepts personal cosigners, what income and credit it requires of them, whether they must live in-state, and which guarantor services it accepts. Apply only where your cosigner clearly meets the standard. That keeps application fees down and spares your cosigner from sharing tax returns with a building that will reject them.

Expect the landlord to ask for higher income and stronger credit than it asks of you. Apartments.com describes a common cosigner standard of income at three or four times the rent with good credit, while New York City buildings often expect 80 times the monthly rent in annual income. Cosigners usually provide pay stubs or tax returns, identification and a signed agreement, and consent to a credit check.

No legal minimum exists, and each property sets its own. Experian says a score of 670 or above is generally preferred for apartment cosigners, Apartments.com describes 680 to 700 or higher as common, and New York City guarantors are typically expected to have at least 700. A cosigner whose score sits near the cutoff should check their own report for errors before applying.

Pricing depends on the company, your rent and your profile. Insurent lists 70 to 90 percent of one month's rent for a one-year guaranty for U.S. applicants and 98 to 110 percent for non-U.S. applicants. TheGuarantors prices each policy individually. In both cases the fee is not returned, and you must repay the company if it ever covers unpaid rent for you.

That depends on your state. New York limits any deposit or advance to one month's rent for most residential leases, which ended the practice of offering extra security there. California caps security at one month's rent for most landlords and two months for certain small landlords. Where your state sets no cap, a larger deposit can substitute for a cosigner if the landlord agrees in writing.

Either the cosigner signs the lease itself, or a separate guaranty or addendum. Either way, the document should state what is covered, such as rent, fees and damages; whether it covers every tenant in the unit; how long the obligation lasts; and whether the landlord must notify the cosigner of a late payment. Because the labels are used loosely, the wording controls.

For as long as the signed document says. Some guaranties end with the initial lease term, while others continue through renewals and extensions until the tenant moves out and the balance is settled. Your cosigner should look for renewal language before signing and ask the landlord to limit the guaranty to the current term if they do not want an open-ended commitment.

The upside is access to apartments you can afford but cannot qualify for alone, usually at no added fee. The downside falls mostly on the cosigner, who may owe rent, fees and damages, sometimes for roommates and renewals too. A missed payment strains a relationship as well as a credit file, which is why a written side agreement helps.

Often, but not always. Some landlords require cosigners or guarantors to live in the same state or region, partly because enforcing the guaranty is easier locally. Ask about residency before your parents send any documents. If the building insists on in-state guarantors, an institutional guarantor service the building accepts is the usual way around it.

Signing the guaranty without reading how long it lasts and whom it covers. Many cosigners assume they are backing one tenant for one year, then learn the document covers every roommate and every renewal. The second common mistake is the renter's: applying before confirming that the building accepts cosigners at all, and burning a fee and a favor in the process.
