If you’ve started house hunting, you’ve probably typed some version of “how much mortgage can I afford?” into Google more than once.
It’s one of the most common questions homebuyers have, and for good reason. The answer shapes almost everything else about your home search — from the neighborhoods you consider to the price range you should be looking at.
There isn’t one magic number.
How much mortgage you can afford depends on several factors that are unique to you, including your income, monthly debts, credit profile, down payment, the type of loan you choose, and the total monthly cost of the home.
I can’t tell you an exact figure in a blog post, but I can walk you through what goes into that number so you’re not going into the homebuying process blind.
Quick note: Everything below is general, educational information — not a quote, an offer, or a guarantee of what you may qualify for. Your actual numbers depend on your income, debts, credit profile, assets, property, and the loan program that fits your situation. The best way to determine what you can actually afford and qualify for is to discuss your specific situation with a licensed mortgage professional.
It Starts With What You Bring In vs. What You Owe
One of the most important numbers lenders look at is your debt-to-income ratio, or DTI.
In plain English, DTI compares your monthly debt obligations with your gross monthly income. Depending on the loan program and your overall financial profile, lenders may consider debts such as:
- Car loans
- Student loans
- Credit card payments
- Personal loans
- Other recurring debts
- Your proposed monthly housing payment
You don’t need to memorize the formula. The important thing to understand is that your existing monthly debt affects how much room you have for a new mortgage payment.
Generally, the less you owe relative to what you earn, the more borrowing capacity you may have.
That’s why one of the first things a loan officer will ask about isn’t the house you want to buy, it’s your income and your existing monthly obligations.
How Much of Your Income Should Go Toward a Mortgage?
You may have heard of the 28% rule, which suggests that your housing payment shouldn’t exceed 28% of your gross monthly income.
It’s a useful rule of thumb for general budgeting, but don’t confuse it with a mortgage qualification requirement.
Mortgage guidelines can vary significantly depending on the loan program and your overall financial profile. A lender doesn’t simply take your income, multiply it by a percentage, and tell you what house you can buy.
Your income, debts, credit, assets, down payment, property taxes, insurance, and loan program can all affect the answer.
In other words, a budgeting rule can give you a starting point, but it can’t give you your actual mortgage number.
Your Down Payment Changes Your Options
This is where things can get interesting because down payment requirements aren’t one-size-fits-all.
Some mortgage programs allow qualified buyers to purchase a home with a relatively small down payment. Others may require or make more sense with a larger amount upfront.
And a larger down payment isn’t automatically the best choice for every buyer.
Putting more money down can reduce the amount you need to borrow and may affect your monthly payment. But you also have to consider how much cash you’ll have left after closing for reserves, moving expenses, repairs, and everything else that comes with owning a home.
The right amount to put down depends on your overall financial picture and the loan program that fits your situation.
Credit Plays a Role, But It’s Not the Whole Story
Your credit profile can affect both your mortgage options and, in many cases, the interest rate you may receive.
But credit isn’t simply a pass-or-fail test.
Two borrowers with the same income can potentially qualify for different mortgage amounts because their credit profiles, debts, down payments, assets, and other financial circumstances are different.
That’s why it’s important to understand where you stand before you start assuming that a particular home price is either affordable or out of reach.
Don’t Forget What Comes After Principal and Interest
Here’s one of the biggest mistakes buyers make when estimating how much mortgage they can afford:
They look only at the principal and interest payment.
Your total monthly housing expense can also include:
- Property taxes
- Homeowners insurance
- Mortgage insurance, if applicable
- HOA dues, if applicable
These costs can add up.
And that’s why two homes with exactly the same purchase price can have noticeably different monthly payments.
For example, property taxes and homeowners insurance can vary depending on the property and location. HOA dues can vary from one neighborhood to another. Mortgage insurance can also affect the payment depending on the loan program and your down payment.
When you’re determining how much mortgage you can afford, make sure you’re looking at the total monthly housing payment, not just the principal and interest.
The Loan Program Can Change the Answer
Another reason there isn’t a universal “how much mortgage can I afford?” number is that different mortgage programs have different guidelines.
Depending on your circumstances, you may have options that include:
- Conventional loans
- FHA loans
- VA loans
- Jumbo loans
- Other specialized mortgage programs
Each program can have different requirements involving credit, down payment, debt-to-income ratios, property eligibility, and other factors.
That’s why it’s usually a mistake to decide which loan program you should use based solely on something you read online.
The best loan isn’t necessarily the one with the lowest down payment or the lowest advertised rate. It’s the one that makes the most sense for your particular financial situation and goals.
Why Online Mortgage Calculators Can Only Tell You So Much
Mortgage calculators can be useful.
They can help you experiment with different home prices, interest rates, down payments, and estimated payments.
But an online calculator doesn’t know your complete financial picture.
It doesn’t necessarily know how a lender will calculate your qualifying income, how your specific debts will be treated, which loan programs you qualify for, or what property taxes, insurance, mortgage insurance, and other costs will apply to the home you’re considering.
Use a calculator as a starting point, not as your approval.
So, How Do I Find My Number?
A mortgage professional can evaluate your income, monthly debts, credit profile, available assets, down payment, goals, and the loan programs that may fit your situation.
This gives you a realistic picture of what you may be able to afford and what your monthly payment could look like.
And just as importantly, it can help you determine what you’re comfortable paying, not simply the maximum amount a lender may allow you to borrow.
If you’re thinking about buying a home in Magnolia, The Woodlands, Spring, Conroe, or anywhere else in Texas and want to know what your numbers look like, I’d be happy to help.
