What Percentage of Your Income Should Go Toward a Mortgage?

When buying a home, one of the most critical financial decisions is determining how much of your income should go toward your mortgage. Striking the right balance ensures that you can comfortably afford your home without stretching your budget too thin. Lenders use various guidelines to help buyers determine affordability, but personal financial goals and lifestyle should also factor into the decision.

General Mortgage Affordability Guidelines
A common rule of thumb is the 28/36 rule, which lenders often use when evaluating mortgage applications:

  • 28% Rule: Your monthly mortgage payment (including principal, interest, property taxes, and homeowners’ insurance) should not exceed 28% of your gross monthly income.
  • 36% Rule: Your total debt payments (mortgage, credit cards, student loans, auto loans, etc.) should not exceed 36% of your gross monthly income.

For example, if you earn $6,000 per month before taxes, your recommended mortgage payment would be around $1,680 (28%), and your total monthly debt obligations should be no more than $2,160 (36%).

Factors That Influence How Much You Should Spend
While the 28/36 rule provides a helpful guideline, several factors may influence how much of your income should go toward your mortgage:

1. Your Debt-to-Income (DTI) Ratio
Lenders use your debt-to-income (DTI) ratio to assess affordability. Some loan programs allow for higher DTIs:

  • Conventional loans typically require a DTI under 43%.
  • FHA loans may allow DTIs up to 50% in some cases.
  • VA loans consider DTI but also look at residual income, offering more flexibility.

A lower DTI makes you a more attractive borrower and may help you qualify for better interest rates.

2. Your Down Payment
A larger down payment reduces the loan amount, which can lower your monthly mortgage payment and improve affordability. If you put down 20% or more, you also avoid private mortgage insurance (PMI), further reducing costs.

3. Your Lifestyle and Financial Goals
Your mortgage payment should allow you to maintain a comfortable lifestyle while saving for retirement, emergencies, and other financial goals. If you prioritize travel, investing, or other expenses, you may want to keep your mortgage below the recommended 28% threshold.

4. Location and Cost of Living
Housing costs vary significantly by location. In high-cost areas, buyers may need to allocate a larger percentage of their income to housing, while in lower-cost regions, a smaller percentage may suffice.

Finding the Right Mortgage Payment for You
To determine an affordable mortgage payment:

  1. Calculate Your Monthly Income – Use gross (pre-tax) income as a starting point.
  2. Factor in Existing Debts – Consider car loans, student loans, credit cards, and other obligations.
  3. Estimate Homeownership Costs – Beyond mortgage payments, account for property taxes, insurance, HOA fees, and maintenance.
  4. Use a Mortgage Calculator – Online tools can help you estimate affordability based on income, interest rates, and loan terms.

While the 28/36 rule provides a solid framework, your ideal mortgage payment should align with your personal financial situation and long-term goals. Before committing to a home loan, assess your budget, factor in all homeownership costs, and ensure you have room for savings and discretionary spending. Consulting with a mortgage professional can help you determine the right loan amount and structure to fit your needs.

How Do Mortgage Lenders Decide How Much You Can Borrow?

When it comes to buying a home, one of the most critical factors to consider is how much you can borrow through a mortgage. Mortgage lenders play a pivotal role in determining your borrowing capacity. We will delve into the intricacies of how mortgage lenders decide how much you can borrow.

Your Income and Debt
One of the primary factors that mortgage lenders consider is your income. They want to ensure that you have a steady source of income to make monthly mortgage payments. Generally, lenders prefer that your housing expenses do not exceed 28% of your gross monthly income.

In addition to your income, lenders will also look at your existing debts. This includes credit card debt, student loans, car loans, and any other outstanding obligations. A lower DTI usually results in a higher borrowing capacity.

Credit Score
Your credit score is another critical element in the lending decision. Lenders use your credit score to assess your creditworthiness. Typically, the higher your credit score, the more you can borrow and the lower your interest rate will be.

Down Payment
The size of your down payment plays a significant role in determining your borrowing capacity. A larger down payment not only reduces the principal amount you need to borrow but also shows your commitment to the purchase.

Loan-to-Value Ratio (LTV)
The Loan-to-Value ratio is the percentage of the home’s appraised value that the lender is willing to finance. A lower LTV ratio indicates a lower risk for the lender, which may result in a larger loan amount.

Interest Rates
The prevailing interest rates in the mortgage market can also impact your borrowing capacity. When rates are low, you may be able to borrow more for the same monthly payment. Conversely, when rates are high, the amount you can borrow may decrease.

Loan Term
The term of your mortgage can influence how much you can borrow. A 15-year mortgage will require higher monthly payments but can result in a larger loan amount compared to a 30-year mortgage.

Mortgage lenders use a complex set of criteria to determine how much you can borrow. Your income, credit score, down payment, debt-to-income ratio, loan-to-value ratio, interest rates, loan term, and financial reserves all come into play. Remember, every lender has slightly different criteria, so it’s essential to shop around and compare offers from various financial institutions to find the best mortgage deal that suits your financial situation and goals.

Why Your ‘Debt-to-Income Ratio’ Number Matters When Obtaining a Mortgage

If you are looking to buy a home, you may want to consider shopping for a loan first. Having your financing squared away ahead of time can make it easier to be taken seriously by buyers and help move along the closing process. For those who are looking to get a mortgage soon, keep in mind that the Debt-to-Income ratio of the borrower plays a huge role in the approval of your mortgage application.

What is a Debt-to-Income Ratio?

A debt-to-income ratio is the percentage of monthly debt payments compared to the amount of gross income that a person earns each month. Your gross monthly income is typically the amount of money you earn before taxes and other deductions are taken out. If a person’s monthly gross income is $2,000 a month and they have monthly debt payments of $1000 each month, that person would have a DTI of 50 percent. The lower the DTI the better. 43 percent is in most cases the highest DTI that potential borrowers can have and still get approved for a mortgage.

What Debt Do Lenders Review?

The good news for borrowers is that lenders will disregard some debt when calculating a borrower’s DTI. For example, utilities, cable, phone and health insurance premium would not be considered as part of your DTI. What lenders will look at are any installment loan obligations such as auto loans or student loans as well as any revolving debt payments such as credit cards or a home equity line of credit. In some cases, a lender will disregard an installment loan debt if the loan is projected to be paid off in the next 10-12 months.

What Is Considered Income?

Almost any source of income that can be verified will be counted as income on a mortgage application. Wage income is considered as part of a borrower’s monthly qualifying income. Self-employed individuals can use their net profit as income when applying for a mortgage, however, many lenders will average income in the current year with income from previous years. In addition, those who receive alimony, investment income or money from a pension or social security should make sure and include those figures in their monthly income as well when applying for a loan.

How Much Debt Is Too Much Debt?

Many lenders prefer to only offer loans to those who have a debt-to-income ratio of 43 percent or lower. Talking to a lender prior to starting the mortgage application process may help a borrower determine if his or her chosen lender offers such leeway.

A borrower’s DTI ratio can be the biggest factor when a lender decides whether to approve a mortgage application. Those who wish to increase their odds of loan approval may decide to lower their DTI by either increasing their income or lowering their debt. This may make it easier for the lender and the underwriter to justify making a loan to the borrower. For more information, contact your local mortgage professional today.
