Most first-time home buyers get approved for somewhere between $200,000 and $450,000, but the actual number depends on a formula your lender applies to your specific finances: gross monthly income, existing debt payments, credit score, down payment, and the loan program you use. In the third quarter of 2025, homes listed at roughly $432,600 on average nationwide, and the typical first-time buyer put down about 10 percent. If you understand how the pieces of the approval formula fit together, you can estimate your own number before you ever talk to a loan officer, and you can see which levers actually move it.
The Formula Behind Your Approval Amount
Lenders start with your gross monthly income, meaning what you earn before taxes and deductions. They want income that is stable and recurring: salary, consistent hourly wages, or documented self-employment profit backed by two years of business tax returns. Reported income gets verified against IRS records using Form 4506-C, so the numbers you put on the application need to match what you filed.1Fannie Mae.

From that income, lenders calculate two debt-to-income ratios. The front-end ratio is your housing payment (principal, interest, property taxes, and homeowners insurance) divided by gross monthly income. The back-end ratio adds every other monthly obligation on top: car loans, student loans, credit card minimums, personal loans. A widely used benchmark is the 28/36 rule: housing at or below 28 percent of gross income, total debt at or below 36 percent.2FDIC. How Much Mortgage Can I Afford
In practice, most programs allow more. FHA loans work off a 31/43 guideline, with flexibility above that for borrowers with cash reserves or a bigger down payment. VA loans use a 41 percent back-end benchmark but focus on residual income, the cash left after all obligations, and will approve above 41 percent when residual income sits roughly 20 percent above the required threshold. Fannie Mae’s automated underwriting system will approve conventional loans with total DTI as high as 50 percent when the borrower brings strong compensating factors like a high credit score or significant reserves.3Fannie Mae.

What the Formula Produces in Dollars
A household earning $6,000 a month gross has a $1,680 housing budget under the 28 percent front-end rule and a $2,160 total debt ceiling under the 36 percent back-end rule. If that household already pays $400 a month on a car and student loans, the room left for a mortgage payment is $1,760. At 7 percent on a 30-year fixed loan, that payment supports a loan of roughly $265,000. Take the same debts but raise income to $10,000 a month, and the supported loan climbs to about $475,000.2FDIC. How Much Mortgage Can I Afford
Two takeaways from that math. Paying down an existing loan before you apply can raise your approval as effectively as a raise, because every dollar of monthly debt payment eaten by other creditors is a dollar the mortgage can’t use. And the interest rate quietly controls everything: at a higher rate, the same monthly payment supports a smaller loan.
How Your Credit Score Changes the Number
Credit score sets the interest rate you are offered, and the interest rate directly determines how much house that DTI-limited payment can buy. Two applicants with identical income and debts, one at 760 and one at 640, can walk out with very different approved amounts. Lenders pull all three bureaus and typically qualify you on the middle score.4Experian. Which Credit Scores Do Mortgage Lenders Use
Score also gates which programs you can use at all:
- Conventional loans generally require a 620 FICO minimum. Scores above 740 unlock the best rates and the lowest private mortgage insurance costs.
- FHA loans require 580 for the standard 3.5 percent down payment. Scores between 500 and 579 can still qualify, but the down payment jumps to 10 percent.
- VA loans have no VA-set minimum, though most VA-approved lenders want at least 620.
- USDA loans usually require 640 at the lender level, even though the program itself sets no hard floor.
If your score sits below where you want it, paying down revolving credit card balances is usually the fastest way to push it up in the months before you apply.
How Loan Type Changes the Ceiling
The program you use shapes both the cash you need upfront and the maximum size of the loan.
Conventional Loans
Standard conventional loans go as low as 3 percent down for first-time buyers through Fannie Mae’s HomeReady mortgage or the 97 percent loan-to-value option. HomeReady is designed for low-income borrowers and allows down payment funds to come entirely from gifts, grants, or community programs, with no personal contribution required.5Fannie Mae. HomeReady Mortgage Conventional loans follow conforming limits set by the Federal Housing Finance Agency: for 2026, $832,750 for a single-family home in most of the country, $1,249,125 in designated high-cost areas, and a statutory ceiling of $1,873,675 in Alaska, Hawaii, Guam, and the U.S. Virgin Islands.6FHFA. FHFA Announces Conforming Loan Limit Values for 2026 Anything above your area’s conforming limit becomes a jumbo loan, with tighter credit standards and usually larger down payments.
FHA Loans
FHA loans require 3.5 percent down with a 580 score, accept higher DTI ratios, and carry FHA loan limits that vary by county and generally sit below conventional conforming limits. The trade-off is mandatory mortgage insurance on every FHA loan regardless of down payment size.
VA Loans
Active-duty service members, veterans, and eligible surviving spouses can get VA-backed loans with zero down. You’ll need a Certificate of Eligibility to prove your service qualifies.7Veterans Affairs. How to Request a VA Home Loan Certificate of Eligibility There’s no private mortgage insurance requirement, which meaningfully lowers the monthly payment against your DTI. The VA doesn’t set a hard loan limit for borrowers with full entitlement, though individual lenders can impose their own caps.
USDA Loans
The USDA’s Single Family Housing Guaranteed Loan Program also offers zero down, with two restrictions: the property must sit in an eligible rural area, and your household income cannot exceed 115 percent of the area median income.8USDA Rural Development. Single Family Home Loan Guarantees Plenty of suburban addresses that don’t feel rural actually qualify, so it’s worth checking the eligibility map before you rule this out.
How Your Down Payment Shifts Your Buying Power
A larger down payment does two things at once. It lowers the loan-to-value ratio, which cuts the lender’s risk and often improves your interest rate. And it directly raises the purchase price you can reach even when the loan itself stays the same size. A buyer approved for a $300,000 loan who puts 3 percent down can buy a home worth roughly $309,000. With 20 percent saved, that same $300,000 loan buys a $375,000 property.
The 20 percent threshold also eliminates private mortgage insurance on conventional loans, which lowers the monthly payment and, by lowering it, gives you room for a larger loan under the same DTI ceiling.
Mortgage Insurance and Your Approval
Under 20 percent down on a conventional loan, you’ll pay private mortgage insurance until your equity reaches a certain level. PMI typically runs between 0.2 and 2 percent of the loan amount per year, depending on credit score and LTV. On a $300,000 loan, that’s $600 to $6,000 a year added to housing costs, and those costs count against your DTI, shrinking the loan you qualify for. Federal law requires your servicer to automatically cancel PMI once your scheduled loan balance hits 78 percent of the home’s original value, as long as you’re current. You can also request cancellation earlier at 80 percent LTV.9CFPB. Homeowners Protection Act PMI Cancellation Act Procedures
FHA loans work differently. Every FHA borrower pays an upfront mortgage insurance premium of 1.75 percent of the loan amount, usually rolled into the loan balance, plus an annual premium. On a 30-year FHA loan with less than 5 percent down and a loan amount at or below $726,200, the annual premium is 0.55 percent. Put less than 10 percent down and FHA mortgage insurance generally stays on the loan for its full life, which is why many first-time buyers refinance into a conventional loan after building equity and improving their credit.
Ways to Raise the Approval Amount
Two moves reliably push the approval up without waiting for a raise.
Gift funds. Family can help cover the down payment, and lenders will accept the money if it comes with a signed gift letter naming the donor, stating the relationship, listing the amount, and confirming no repayment is expected.10Fannie Mae. Personal Gifts The transfer gets verified through bank statements on both sides. If there is any expectation of repayment, it’s a loan, and it will land in your DTI as debt.
A non-occupant co-borrower. Adding a parent or other co-borrower folds their income into the DTI calculation, which can substantially raise the qualifying loan amount. Their debts fold in too, and they take on full legal liability for the mortgage.11Fannie Mae. Non-Occupant Borrowers There’s no separate DTI requirement for the person actually living in the home; the ratio uses everyone’s combined income and liabilities.
Costs That Quietly Shrink the Number
The approved loan amount isn’t the whole picture. Closing costs typically run 2 to 5 percent of the purchase price, covering lender fees, title insurance, appraisal, and prepaid items like taxes and insurance. On a $350,000 home, that’s $7,000 to $17,500 you need beyond the down payment. Some first-time buyer programs let the seller contribute toward closing costs, and certain loan types cap the fees you can be charged, but plan on the expense from the start.
Property taxes and homeowners insurance also work against your approval, because they sit inside the monthly housing payment your DTI has to accommodate. Effective property tax rates range from under 0.3 percent to over 2 percent of home value across the country. Buying in a high-tax area means more of your allowed payment gets absorbed by taxes and less is available for the mortgage itself, which reduces the purchase price you can actually reach.
What the Pre-Approval Letter Tells You
Once you submit an application, the lender runs a hard credit inquiry and returns a decision, usually within one to three business days. If you’re comparing several lenders, credit scoring models generally treat all mortgage-related inquiries within a 14- to 45-day window as a single inquiry, so rate shopping won’t damage your score.
The pre-approval letter states your maximum approved loan amount, the anticipated interest rate, and the loan term. That maximum is your ceiling, not a target. A payment that fits the lender’s DTI formula can still crowd out savings, retirement contributions, and everything else you spend money on, so the number you should offer at is often lower than the number the letter allows. Letters typically expire in 60 to 90 days, sometimes 30, so hold off on pre-approval until you’re genuinely ready to make offers.
