One rule of thumb when buying a home is to not spend more than three times your annual salary. If you earn $40K a year, that means you can afford to spend around $120,000 on a house, maybe a bit more if you have little or no other debts and a large down payment. However, depending on where you want to live, interest rates, and how much debt you’re carrying, that figure could change significantly.
Understanding how these factors play into home affordability can get you closer to finding a home you can afford on your $40,000 salary.

Key Points
• It’s recommended to not spend more than three times your annual income on a mortgage. With a $40,000/year salary, that means your mortgage should be no more than $120,000.
• Lenders typically prefer that your housing expenses (mortgage, property taxes, insurance) do not exceed 28% of your monthly income.
• Saving a 20% down payment can help you avoid private mortgage insurance (PMI) and secure better loan terms.
• The cost of living and housing market in your area significantly impact how much house you can afford.
• Various types of home loans are available, including conventional, FHA, USDA, and VA loans, each with different criteria.
What Kind of House Can I Afford With $40K a Year?
If you earn around $40,000 per year, the kind of house you can afford typically depends on your debt, down payment, and local housing costs, but generally, you could afford a home mortgage loan of around $120,000.
This estimate assumes you have little to no other debt, a stable credit score, and can make a modest down payment. Shopping in areas with lower property taxes and considering first-time homebuyer programs or down payment assistance can also help you stretch your budget.
Understanding Debt-to-income Ratio
When purchasing a home, a potential lender will calculate your debt-to-income (DTI) ratio by adding all your monthly debts and dividing that number by your monthly income.
Your DTI ratio determines how much home you can afford. If you have more debt, you can’t afford a bigger monthly housing payment, which means you’ll qualify for a smaller home loan. For example, if your total debt amounts are $3,000 each month and your income is $6,000 per month, your debt-to-income ratio would be 50%. This is well above the 36% guideline many mortgage lenders want to see.
💡 Quick Tip: To see a house in person, particularly in a tight or expensive market, you may need to show the real estate agent proof that you’re preapproved for a mortgage. SoFi’s online application makes the process simple.

How to Factor in Your Down Payment
A down payment can also drastically impact home affordability. If you have a larger down payment, you’ll be able to afford a higher-priced home. With a down payment of 20% or more, you’ll be able to avoid the added expense of private mortgage insurance (PMI), which will in turn increase the loan amount you’ll be able to qualify for.
Try using a mortgage calculator to see how different down payment amounts can affect how much home you’ll be able to qualify for.
Factors That Affect Home Affordability
To complete the picture of home affordability, you’ll also need to consider these factors:
• Interest rates: A higher interest rate means you’ll qualify for a smaller home purchase price. A lower interest rate increases how much home you’ll be able to afford. To qualify for a better interest rate, work on building your credit score.
• Credit history and score: Your credit score directly affects home affordability. With a good credit score, you’ll qualify for a better rate, which means you may qualify for a higher mortgage.
• Taxes and insurance: Higher taxes and insurance can also affect home affordability. Your lender has to take into account how much you’ll be paying and include it as part of your monthly payment.
• Loan type: Different loan types have different interest rates, down payment options, and credit requirements, which can affect home affordability.
• Lender: Your lender may be able to approve you at a higher DTI ratio — some lenders will allow the DTI to be as much as 50%.
• Area: The cost of living in your state is a top factor in determining home affordability. Price varies greatly around the country, so you may want to consider moving to a more affordable area, if possible.

How to Afford More House With Down Payment Assistance
If you make $40,000, how much house you can afford also depends on what programs you’re able to qualify for. Down payment assistance programs can help with home affordability. These programs offer a grant or a second mortgage to cover a down payment, and are often offered by the state or city you live in.
They may be restricted to first-time homebuyers or low-income borrowers, but these programs are worth looking into. Examples include Washington state’s Home Advantage DPA and Virginia’s HOMEownership DPA. Look for programs in your state, county, and city.

How to Calculate How Much House You Can Afford
Lenders often follow the 28/36 rule, looking for a housing payment less than 28% of a borrower’s income and total debt payments less than 36% of your income. Here’s how to calculate it.
Back-end ratio (36%): The back-end ratio is your debt-to-income ratio. Add together all of your debts (including the new mortgage payment) to make sure all debts are under 36% of your income. If your monthly income is $3,333 ($40,000/12 = $3,333), your debts (including the mortgage payment) should be no more than $1,200 ($3,333*.36).
Front-end ratio (28%): With a monthly income of $3,333, this number works out to $933.
The 35/45 Rule: It’s possible to qualify for a larger mortgage based on the 35/45 guideline, which is used at the discretion of your lender. With a monthly income of $3,333, the housing allowance (35% of your income) increases to $1,167 and the total monthly debts (45% of your income) increases to $1,500.
An easy way to calculate how much home you can afford is with a home affordability calculator.
Home Affordability Examples
For homebuyers with a $40,000 annual income ($3,333 per month), traditional guidelines of a 36% debt-to-income ratio give a maximum house payment of $1,200 ($3,333 * .36). Each example has the same amount for taxes ($2,500), insurance ($1,000), and APR (6%) for a 30-year loan term.
Example #1: Too much debt
Monthly credit card debt: $100
Monthly car payment: $300
Student loan payment: $300
Total debt = $700 total debt payments
Down payment = $20,000
Maximum DTI ratio = $3,333 * .36 = $1,200
Maximum mortgage payment = $500 ($1,200 – $700)
Home budget = $54,748
Example #2: Low-debt borrower
Monthly credit card debt: $0
Monthly car payment: $100
Student loan payment: $0
Total debt = $100
Down payment: $20,000
Maximum DTI ratio = $3,333 * .36 = $1,200
Maximum mortgage payment = $1,100 ($1,200 – $100)
Home budget = $141,791
How Your Monthly Payment Affects Your Price Range
As shown above, your monthly debt obligations affect how much house you can afford. With significant debt, it’s hard to make a mortgage payment that qualifies you for the home you want.
It’s also important to keep in mind how interest rates affect your monthly payment. By paying so much interest over the course of 30 years, even small fluctuations in interest rates will affect your monthly payment. That’s why you see your neighbors scrambling to refinance their mortgages when interest rates drop.
Types of Home Loans Available to $40K Households
There are different types of mortgage loans available for households in the $40K range:
• FHA loans: With Federal Housing Administration (FHA) loans, you don’t have to have perfect credit or a large down payment to qualify. In fact, you can apply for an FHA loan with a credit score as low as 500.
• USDA loans: If you live in a rural area, you’ll definitely want to look at United States Department of Agriculture (USDA) loans. You may be able to qualify for a USDA mortgage with no down payment and competitive interest rates.
• Conventional loans: For borrowers with stronger financials, conventional loans are some of the least expensive mortgages in terms of interest rates, mortgage insurance premiums, and property requirements. They’re backed by the federal government, and if you’re able to qualify for a conventional mortgage, it could save you some money.
• VA loans: For qualified veterans and servicemembers, the U.S. Department of Veterans Affairs (VA) loan is quite possibly the best out there. There are zero down payment options with great interest rates. If your credit is hurting, you still might be able to get a loan since the VA doesn’t have minimum credit score requirements (though the individual lender may).
The Takeaway
With proper planning, a salary of $40K should be able to get you into a home in many U.S. markets. However, you’ll want to make sure you keep a close eye on your credit score and save up for a down payment or find programs to help with one. Over time, the small, determined steps you take will lead you to your goals.
