“I’m sorry, but you need a regular income and a good credit rating to lease one of our apartments,” Mary Keller explained to the anxious 20-year-old student eager to lease a one-bedroom unit in the popular Harlan House Apartments near the University of Arkansas.
The young coed, shaking her head to emphasize her disappointment, exclaims, “But I have my own bank account, and my parents send me money every month. I promise that I will pay the rent on time.”
According to a TransUnion poll, rent payment problems are the number one concern of real estate property owners. From experience, they know renting an apartment to someone with a sketchy, limited, or no credit history often leads to payment problems.
Of course, college students are not the only group of potential tenants that have dubious financial credentials. Credit reporting agencies estimate that 30% of Americans have credit scores below 600, considered either “poor” or “bad” credit risks. Most are renters, unable to buy homes.
How to treat prospective tenants with poor credit is a dilemma for most rental property owners. Restricting leases to those with high incomes and excellent credit scores are likely to extend vacancy rates and lower rental income. On the other hand, no landlord wants to chase deadbeats or professional tenants for the rent and suffer through the eviction process. Or, for that matter, to try and collect debts from an ex-tenant who has little assets of value or an irregular, minimum income is expensive and frustrating.
Fortunately, there is an alternative to rejecting a tenant outright: Securing a co-signer on the lease.
What Is a Co-Signer for a Lease?
A co-signer on a lease agreement assumes the same legal responsibilities as the tenant who signs the lease and will live in the rented property. If the lessee (tenant) fails to pay the rent, the landlord can require the co-signer to pay, including specified penalties and fees. Also, co-signers are typically responsible for any damage caused by the tenant or touch-ups if included in the co-signed rental contract.
Individual states have different laws regarding lease and co-signer agreements, including conditions and procedures to require payment by the co-signer. Failure to follow the prescribed process may render the co-signer agreement void or limit the damages associated with it. Since the penalties for non-compliance can be severe, landlords should always check the terms of their proffered lease agreement and associated documents with an attorney.
Co-signer vs. Guarantor: What’s the Difference?
Non-specialists typically use the term interchangeably, but they may not be the same in practice depending on the relevant state law:
- Co-signers. If a person co-signs a real estate lease, they and the lessee are jointly and separately responsible for the performance of the contract terms. In the event of a default, the landlord can require either or both to cure the default. Practically speaking, the landlord will pursue collection from the party most capable of payment.
- Guarantors. Depending on state law, a guarantor may not be a party to the lease itself, but guarantees the performance of a lessee to comply with the rental agreement. Legally, a guarantor has a contingent liability, not the direct obligation of a co-signer. In other words, the guarantee contract may require the landlord to legally declare the lessee in default before they can pursue the guarantor for payment. As a consequence, collecting from a guarantor may be more expensive and time-consuming than a co-signer.
Be sure you understand the difference between a co-signer vs. a guarantor for a lease – if any – in your state. Always use the lease contract that provides the maximum leeway and least expense to collect your delinquent rents.
Does the Law Ever Require the Use of Co-Signer Agreements?
No, a landlord is not legally required to offer potential renters an option to add a lease co-signer when the applicant does not meet the landlord’s credit requirements.
Should You Consider Requiring a Lease Co-Signer?
Property managers and owners need to know the benefits and risks of requiring co-signers on a lease agreement. Properly employed, their use can boost your occupancy rate and reduce the financial costs of delinquent tenants. Conversely, careless or improper use of the strategy can increase costs and headaches of owners.
Benefits of a Co-Signer Program
Rental property owners use co-signer agreements to:
- Expand the number of potential tenants. In some cases, allowing lease co-signers may be practically necessary. Landlords with property in a college town who cater to students often use co-signers since young applicants with minimal credit histories make tenant screening tools
- Gain a competitive advantage. In competitive markets, some landlords may target tenants that others consider “high risk” to maintain high occupancy rates and rents. Recent emigrants to the U.S., illegal immigrants and those with criminal records typically lack extensive credit or residential histories. A creditable co-signer, whether an individual or organization, indicates that a prospective tenant has a support system that will encourage the renter’s compliance with the terms of the lease.
- Reduce financial risk. Using a co-signer transfers the risk of rental delinquencies from the property owner to the co-signer on the lease. Even some Section 8 housing property owners require co-signers for the portion of rent not covered by the government program. Of course, the effectiveness of a co-signer strategy depends on the financial capability of the potential guarantor and the landlord’s ability to enforce the co-signer agreement.
Yet despite the real benefits of a co-signer strategy, they shouldn’t be used to justify signing a lease with a fundamentally irresponsible tenant. Using a co-signer on a lease agreement is not a cure-all, and comes with limitations.
Limitations of Lease Co-Signer Programs
Having a co-signer on an apartment lease is one way to reduce the financial risk of delinquent rents, but not without risks for the real estate owner. Impulsive or careless use of a third-party guarantee can create more complicated collection efforts and expose landlords to lawsuits and financial penalties.
Before adopting a co-signer program, consider the following risks:
- Tenant behavior. A co-signer can reduce the financial risks of leasing to a questionable tenant, but will not protect a landlord from noise complaints, property damage, aggressive or inappropriate actions.
- Additional costs and inconvenience. An effective co-signer strategy is much more than getting a second signature on a lease agreement. Landlords could incur legal and administrative expenses to develop the legal document and train employees in its use. Verifying the guarantor’s details requires the same tenant screening reports and other efforts as screening the lease applicant.
- Poor screening. Merely adding a third-party to a contract is no guarantee of performance, especially if the co-signer is incapable or unwilling to comply with the terms of the agreement. Landlords should follow the same due diligence process for a co-signer as they do for a lessee. Specifically, a co-signer must have the income and financial assets needed to step in and pay in the event of a rent default. And, for that matter, the will to do so, as demonstrated by strong credit history.
- Inadequate agreements. Remember that few co-signers are happy or eager to meet an unexpected, indirect obligation and will pursue every opportunity to delay or escape payment. Ensure that your lease co-signer agreement meets your state’s legal standard before its use to avoid unpleasant surprises when trying to collect from the guarantor.
- Collection process errors. Due to past abuses and aggressive tenant associations, most states have defined specific steps to follow when pursuing delinquent rents. Failing to follow the process correctly can invalidate collection efforts and may expose the landlord to damages from the tenant or a co-signer. Landlords must adopt, document, and communicate specific procedures to be followed in collection efforts.
In summary, landlords should ensure that a prospective co-signer or guarantor fully understands and agrees to:
- the obligations that they are assuming,
- the high probability that they may be called upon to make delinquent payments, and
- the process by which the landlord will pursue collections.
Some attorneys recommend language where a co-signer explicitly relinquishes the right to protest or otherwise delay payments to the landlord. Ideally, these details will be prominently displayed or referred to in the co-signer agreement. Always better to be safe than sorry!

The Importance of Screening Tenants
In a perfect world, rental tenants would be sterling credit risks, outstanding citizens, and long-term residents that never object to rent increases. Unfortunately, rental applicants often fail to fit that description in the real world. Which is precisely why screening tenants remains arguably the single most important task that landlords undertake.
Proper rental screening processes include:
- Reviewing of the rental application. Your rental application should document demographic details (name, age, a legal identifier such as a Social Security number, permanent address, phone number, and email address), employment history for at least ten years including income, and references.
- Applicant’s authorization to perform a record search. The rental application should contain language to allow the property owner to conduct multiple data searches while also summarizing the prospect’s rights under the Fair Credit Reporting Act (FCRA). Landlords can charge a non-refundable application fee in most states but must have written authorization from the candidate before doing any search. (Hint: You can include tenant screening reports with our rental application, and charge them directly to the applicant. Just sayin’.)
- Background checks. Landlords should verify all employer references. Obtain credit histories, and execute confidential searches of relevant court records such as landlord/tenant disputes, criminal record, and sex offender status.s
- Housing history verification. Call current and former landlords as part of the tenant screening process, and verify that they’ve paid their rent on time every single month of their tenancy.
Despite their frequent use, lease co-signer agreements are not a substitute for thorough tenant screening. Since a co-signer or guarantor is subject to the same obligations as the tenant, they should be subject to the same screening process. A co-signer who cannot pass the lessor’s requirements eliminates little payment risk.
Other Ways to Protect Yourself as a Landlord
Wearing suspenders in addition to a belt seems like overkill until your belt breaks. Using lease co-signers is a popular strategy to reduce rental payment risks, but it’s not the only one.
One relatively recent option for landlords is buying rent default insurance. For a few hundred dollars a year (typically $300-450), landlords can sleep at night knowing that if their tenant defaults on rent, the insurance kicks in and starts paying it until they’ve gone through the eviction process and signed a lease with a new tenant. Check out Steady if you’re new to the idea of rent default insurance, to get a free rate quote.
Security deposits offer another form of protection. Landlords can usually keep the security deposit, if the tenant fails to pay rent or damages the rental unit.
But strategies like co-signers and security deposits are not fail-proof. Landlords make security deposit mistakes all the time, many of which can render the deposit forfeit. State laws may limit the availability of security deposits to specific amounts or circumstances. Failure to properly administer a security deposit account can erupt into administrative nightmares.
Many tenants also perform better if they feel that they have a stake in the property – and that they must pay rent on time to keep that stake. Landlords can offer a rent-to-own program or option to purchase as another incentive to keep tenants performing in line with the lease contract.
Final Thoughts
Electing to accept co-signers or requiring security deposits may reduce your risk of future delinquent payments. However, you must apply the same treatment to all prospective tenants in a similar condition. Federal and state fair housing laws prohibit discrimination for certain protected classes of people based on race, religion, national origin, familial status, age, disability, or gender. For example, Landlords must treat single mothers with low income the same as single men with the same income.
Rather than rent to applicants with questionable financial histories, many landlords counter the risk of lower occupancy rates with aggressive rental marketing campaigns and tenant retention programs. Will such strategies be more successful than the use of co-signers? It depends because each property varies by location, offers different amenities, and appeals to a different market demographic. Real estate investors have different financial goals, capabilities, and risk tolerance. Each investor must make the decisions that best fit their circumstances and are most likely to be successful.
Do you accept lease co-signers for applicants with poor or no credit history? How has it worked out for you? Does the reduced financial risk justify the additional administration?

I’m thinking about investing in a property in a college town and this is a concern that I have. This was a great article. Thank you.
Glad to hear it was useful for you Keirsten!
Having a co signer to sign the lease is sure a great way to open your arms for those tenants also who struggle to fulfil some parts of your rental criteria. Every landlord must consider this option as it is good for the business. Even i mentioned about the terms of when a co signer is required, outright into my rental criteria. I feel it gives me a edge in securing good tenants for my property
It’s absolutely worth outlining this in a set policy. That way, you can always point to it whenever tenants question you.
I’d like to say that during a difficult time in my life being able to secure lodgings due to a landlord who allowed a co-signer, kept me in both a job and in college. It was written into the lease, it was for 1 year. The co-signer never had to pay any portion of my rent, the rent was never late, and after a year a new lease was signed sans co-signer. Whenever I can I mention this as it turned my life around. I realize not every story has a happy ending, but mine did.
Thanks for the article and the above comments.

Glad to hear you had such success with a cosigner on your lease agreement Trish!
Thank you for this article. I still have a question. If I have a cosigner sign the lease and it says no pets and then the tenant gets an ESA, can I hold the cosigner responsible for any damage?
Hi Julie, the cosigner is fully liable for damage to your property, as if they were a tenant living in the property as well.
