Co-Signing a Rental Lease: What You Need to Know

Whether you need a co-signer or are considering being a co-signer, there are important details you need to consider before signing a lease.

Whether you're lending a hand or taking the hand, co-signing on a lease is a serious matter. Read on for helpful tips for both parties.

Renting a home can be an exciting yet challenging process, especially if you are a first-time renter or have limited credit history. In such cases, having a co-signer can make all the difference. Let's explore the key aspects of having a co-signer for a home rental and being a co-signer for someone looking to rent. Understanding these roles will help you make informed decisions and ensure a smooth rental experience.


1. Having a Co-Signer for a Rental Lease:

When you are the primary tenant and require a co-signer, there are a few crucial points to consider:

  • Creditworthiness: Landlords often require co-signers when tenants have insufficient credit history or low credit scores. A co-signer with good credit can boost your chances of getting approved for the rental lease. Typically a minimum of credit score of 700 and an income of at least three times the monthly rent are requried.
  • Financial Responsibility: As the primary tenant, it is essential to understand that you remain financially responsible for the lease agreement. However, having a co-signer means they are equally liable for any unpaid rent or damages.
  • Trust and Communication: Open and honest communication with your co-signer is crucial. Ensure they understand their role and responsibilities, including potential financial risks. It's important to maintain trust and keep them informed throughout the tenancy.
  • Your Relationship: A co-signer does not have to be someone you are related to, but it should be someone that you know well. And a co-signer doesn't even have to live in the same place as the home you are looking to rent. If you are considering having a parent co-sign for you, they don't have to live in the same town. Or if you have a friend who wants to help you out, they can be a co-signer as well. There doesn't have to be a specific relationship or a specific location, for someone to co-sign for you. Just remember the implications for both parties involved.


After you have found a co-signer, it is important to keep your co-signer involved throughout the process of selecting a rental home and leading up to signing the rental agreement. You will need to provide your co-signer with information about the rental property and the lease agreement. This includes the address of the property, the amount of the rent, and the terms of the lease. Your co-signer will need to as involved in the process as you are to ensure that it is a good fit for you as the renter and your budget, and also something that they are comfortable with, in the instance that you cannot make a payment. Bring them with you while you tour units and homes. Let them be in on communication with the Leasing Specialists. All of this will help promote good, transparent communication from the start of the relationship.


It is very important to remember that your co-signer will need to sign the lease agreement along with you. This makes them legally responsible for the rent and other obligations of the lease.


2. Being a Co-Signer for Someone Looking to Rent:

If you are considering being a co-signer for someone else's rental lease, here's what you need to know:

  • Financial Liability: As a co-signer, you are legally responsible for the lease agreement alongside the primary tenant. This means that if the tenant fails to pay rent or causes damages, you could be held accountable.
  • Trust and Relationship: Being a co-signer requires trust in the primary tenant's ability to fulfill their obligations. Make sure you have a strong relationship with the tenant and have confidence in their financial stability and responsibility. You don't have to be related to them in anyway, but you do have to make sure that you trust them and their ability to fulfill the financial requirements of the rental.
  • Credit Implications: Co-signing a lease can impact your credit score, as it becomes part of your credit history. Ensure that you are aware of the potential consequences and how it may affect your future financial decisions.


Here are some additional things to consider before agreeing to co-sign for someone:

  • How well do you know the tenant? If you are co-signing for a friend or family member, you are more likely to be familiar with their financial situation and rental history. However, even if you know the tenant well, it is important to be aware of the risks involved in co-signing for their lease. Remember, as a co-signer, you will be legally responsible for any unpaid rent or damages caused by the primary tenant. Therefore, it is crucial that you have complete faith in their ability to fulfill their obligations.
  • How well do you know the tenant's roommates? If the person you are co-signing for will have roommates, be sure that you know those individuals as well and trust them to uphold their side of the rental agreement. You are still legally responsible for the full amount of the rent if the roommates fail to pay rent. This means that the landlord can come after you for the unpaid rent, even if the you and/or the person you co-signed for have paid their share. Put simply, you aren't just co-signing for one person on the lease, you are co-signing for everyone on the lease.
  • What is your financial situation? Can you afford to make the rent payments if the tenant fails to do so? It is important to be realistic about your financial capabilities before co-signing for a lease.
  • What are the terms of the lease agreement? Be sure to read and understand the lease agreement before you sign it. This includes understanding the length of the lease, the amount of the rent, the security deposit and move in and out fees, and the tenant's obligations. And if their are roommates involved, be sure you ask about and understand their roommates' financial situation and their plans for paying the rent.


Co-signing a home rental lease can be a beneficial arrangement for both parties involved. As the primary tenant, having a co-signer can increase your chances of securing a lease, especially if you have limited credit history. Being a co-signer can help someone who may not meet the landlord's criteria on their own, such as having a low credit score or insufficient income. Co-signing allows them to have access to housing that they might not otherwise be able to obtain.


It is recommended that both parties have open and honest communication about expectations and responsibilities before any lease agreements are signed by either party. This isn't an arrangement that should be entered into lightly and should be taken very seriously by all parties involved. Having everything in writing through a co-signer agreement is ideal to ensure that both parties are covered in the instance that something goes wrong. This will help ensure a smooth and successful rental experience for everyone involved.


Once the lease has been signed, its important that both the co-signer and the tenant continue to talk regularly about the tenant's financial situation and their plans for paying the rent. As the tenant with a co-signer, don't think of it as meddling, think of it as mentoring to ensure a successful financial future. Remember, your co-signer took a serious risk in agreeing to be your co-signer. They have a right to know the status of your finances and ensure that their own finances are secure throughout the length of your lease agreement.


If the rental home is being leased by Miller Family Properties and you will need a co-signer or if you are the co-signer, be sure to ask our Leasing Specialist for more details. And regardless of whether the rental is from us or another company, it is very important that all parties involved review all leasing documents, fees and deposits to ensure full transparency in what sort of financial commitment is required by signing. Neither party wants to damage the relationship with the other over money. Honesty and communication are necessary for any co-signer arrangement to be successful.
