How Rental Income Affects Debt-to-Income Ratio

Published:
February 22, 2025

Understanding how rental income impacts your Debt-to-Income (DTI) ratio is essential if you're applying for loans or investing in rental properties. Here's the key takeaway: Lenders usually count 75% of your rental income as part of your gross income, while including the full property expenses as debt. This ensures they account for vacancies and maintenance costs.

Quick Facts:

  • DTI Formula: Monthly debt payments ÷ Gross monthly income.
  • Rental Income in DTI: Only 75% of gross rental income is considered.
  • Loan Approval DTI Limits: Typically under 43-45% for conventional loans, up to 50% for FHA loans.
  • Example: If a rental earns $1,500/month but costs $1,300 in expenses, it increases your DTI since $1,125 (75% of rent) is less than the expenses.

To improve your DTI:

  • Pay off debts or refinance for lower monthly payments.
  • Increase income through side hustles or better-paying jobs.
  • Keep detailed records of rental income and expenses for lender documentation.

Rental income can help or hurt your DTI depending on how well it offsets property costs. Choose lenders who specialize in investment properties for more flexible terms.

How Do Rental Properties Affect Debt to Income Ratios

What is Debt-to-Income Ratio?

Debt-to-income ratio (DTI) is a financial metric that helps lenders determine if a borrower can handle monthly loan payments. The Consumer Financial Protection Bureau explains:

Your debt-to-income ratio (DTI) is all your monthly debt payments divided by your gross monthly income. This number is one way lenders measure your ability to manage the monthly payments to repay the money you plan to borrow.

How to Calculate DTI

DTI is calculated by dividing your total monthly debt payments by your gross monthly income, then converting the result into a percentage. Typical monthly debts include:

  • Mortgage or rent payments
  • Car loans
  • Student loans
  • Credit card payments
  • Personal loans
  • Home equity lines of credit (HELOCs)
  • Child support or alimony payments

Gross monthly income includes earnings from sources like salary, wages, freelance work, bonuses, child support received, social security benefits, and qualifying rental income .

Example: If your monthly expenses include $1,200 for rent, $400 for a car loan, and $200 in credit card payments, and your gross monthly income is $6,000, your DTI would be 30% .

DTI Limits and Loan Approval

Lenders impose DTI limits that depend on the type of loan and the borrower's financial profile. A lower DTI is generally preferred because it shows that you have more income available to cover your financial obligations. For investment property loans, lenders often expect a lower DTI due to the added risks and responsibilities tied to managing rental properties. Next, we’ll explore how rental income plays into these calculations.

Rental Income in DTI Calculations

Qualifying Rental Income

When calculating debt-to-income (DTI) ratios, lenders typically use 75% of gross rental income. For instance, if a rental property earns $2,000 per month, only $1,500 is considered as qualifying income. This approach prevents lenders from overestimating the rental income's contribution.

"Generally its 75% of gross rents - PITIA = net rental income added to 'income,' if its a negative number its added as a 'liability,' that you'll have to qualify for in your ratios." - Albert Bui, Pro Member, Lender

Now, let’s look at how property expenses influence this calculation.

Property Cost Impact

Several property-related expenses are factored into DTI calculations, including:

  • Monthly mortgage payments (principal and interest)
  • Property taxes
  • Insurance premiums
  • HOA fees
  • Maintenance costs

Some lenders adjust Schedule E income by adding back depreciation, mortgage interest, property taxes, and insurance costs before subtracting the total mortgage payment . This adjustment helps paint a clearer picture of how rental property finances impact DTI.

Sample DTI Calculation

Here’s an example to show how these numbers come together:

Property Details:

  • Monthly Rental Income: $1,500
  • Monthly Mortgage Payment: $1,000
  • Property Taxes and Insurance: $200
  • HOA Fees: $100

DTI Breakdown:

  1. Qualifying Rental Income: $1,500 × 75% = $1,125
  2. Total Monthly Property Expenses: $1,300 ($1,000 + $200 + $100)
  3. Net Impact on DTI: –$175 ($1,125 – $1,300)

In this scenario, the rental property increases your DTI because the qualifying income doesn’t fully cover the expenses.

Ways to Improve Your DTI Ratio

Once you understand how rental income impacts your Debt-to-Income (DTI) ratio, you can take steps to improve it through better debt management, boosting your income, and ensuring proper documentation.

Lower Debt or Increase Income

To improve your DTI ratio, focus on cutting down debt or finding ways to earn more. For instance, refinancing loans at lower interest rates (e.g., 4.5% instead of 6%) can reduce monthly payments and improve your DTI .

Here are some ways to reduce debt:

  • Transfer high-interest credit card balances to lower-rate cards.
  • Refinance mortgages, car loans, or student loans.
  • Explore student loan forgiveness programs.
  • Pay off smaller debts to free up cash flow.

To increase income, consider these options:

  • Start an online business or side hustle.
  • Rent out a room in your home.
  • Negotiate a raise with your employer.
  • Look for a higher-paying job.

Accurate and up-to-date documentation is key to supporting these efforts.

Required Rental Documents

Proper documentation is crucial when using rental income to improve your DTI. Here's what you'll need:

Documentation Type Purpose When to Use
Schedule E Tax Returns Shows historical rental income For properties owned 1+ years
Current Lease Agreements Validates current rental rates For recently purchased properties
Bank Statements Confirms receipt of rental payments To support lease agreements
Appraisal Reports (Form 1007/1025) Validates market rent rates For new rental properties

If you’re reporting rental income, include it on Schedule E. For properties without a tax history, provide current lease agreements along with bank statements that show rental deposits .

Investment Property Lenders

The lender you choose can play a big role in managing your DTI. Different lenders have varying DTI limits: Conventional loans typically cap DTI at 43-45%, FHA loans may allow up to 50%, and VA loans don’t have a fixed maximum .

Some investment-focused lenders, like LoanGuys.com, offer more flexible DTI options for self-employed borrowers, owners of multiple properties, or those seeking no-documentation loans. Portfolio lenders, who keep loans in-house, can also tailor solutions to fit your investment strategy .

Summary

Rental income plays a big role in determining your debt-to-income (DTI) ratio and loan eligibility. Here's what you need to know:

Lenders typically count 75% of your rental income as part of your earnings, while including the full property expenses as debt . Most prefer a DTI ratio under 36%, though some may accept up to 45-50% for borrowers with strong qualifications . Investment-focused lenders, like LoanGuys.com, often provide tailored programs, including no-doc financing options, which can bypass standard DTI calculations.

To keep your DTI manageable while growing your rental portfolio:

  • Look for properties in areas where rental income can comfortably cover mortgage costs .
  • Consider making larger down payments to reduce monthly payments .
  • Keep detailed records of rental income, such as tax returns, lease agreements, and bank statements.
  • Partner with lenders who specialize in investment property financing and offer more flexible DTI terms.

Since DTI calculations can vary between lenders , it's worth exploring different options to find one that fits your investment goals.
