How to Qualify for a Loan Using a Roommate

Thinking about buying a home but worried your income alone won’t be enough to qualify for a mortgage? You might be able to use your roommate’s rent payments—known as boarder income—to strengthen your loan application. In this guide, we’ll break down how boarder income works, what lenders require, how to calculate it, and tips to improve your chances of mortgage approval.
 

What Is Boarder Income and Why Does it Matter?

Boarder income refers to the rent you receive from someone living in your home, such as a roommate. When properly documented, this income can help you:
  • Increase your total qualifying income
  • Improve your debt-to-income (DTI) ratio
  • Offset monthly mortgage costs
  • Strengthen your financial profile for lenders
For example, if your roommate pays $800/month in rent, that income could help you meet the lender’s minimum income requirements and qualify for a larger loan amount.
 

Requirements to Use Roommate Income for Mortgage Qualification

Lenders have strict guidelines when it comes to using boarder income. Here’s what you’ll typically need:
  • Proof of consistent rental payments: Bank statements, cashed checks, or payment receipts showing regular income from your roommate.
  • A formal rental agreement: A signed lease or rental contract outlining the rent amount, payment schedule, and duration of the arrangement.
  • Two-year rental history (in some cases): Some mortgage programs require a documented history of receiving boarder income for at least 12–24 months.
Tip: Be transparent with your lender about your intent to use roommate income. They may request additional documentation to verify its stability.
 

Choosing the Right Mortgage Product

When it comes to qualifying for a loan using a roommate for boarder income, it's important to compare mortgage options that are suitable for this specific situation. Not all mortgage products are created equal, and some may be more accommodating to your unique circumstances.

If you have a history of boarder income and would like to try and use that income to help you qualify for a new home, speak with a loan officer about your options. There are programs available that allow for boarder income, however you must meet all the requirements and have proper documentation.
 

How Do Lenders Calculate Boarder Income?

When evaluating boarder income, lenders look at:
  • Stability: Is the income consistent and likely to continue?
  • Rental history: Have you received payments for at least 12–24 months?
  • Vacancy risk: Are there gaps in rental payments or frequent changes in roommates?
To strengthen your application, maintain a clear record of payments and minimize turnover. The more stable your rental arrangement, the more likely lenders are to count it toward your qualifying income.
 

Tips for a Successful Mortgage Application Using Roommate Income

Here’s how to present your roommate income effectively:
  1. Document Everything: Keep a written lease agreement and track rent payments through bank statements or receipts. Lenders need proof of consistency.
  2. Maintain Strong Personal Finances: Your credit score, employment history, and overall financial health still matter. Pay bills on time, keep your DTI ratio low, and avoid new debt before applying.
  3. Highlight Compensating Factors: If your roommate income alone isn’t enough, emphasize other strengths like a large down payment, long-term employment, or excellent credit. These can offset weaker areas in your application.
