You can increase your mortgage pre-approval amount by lowering your monthly debt payments, raising your credit score, documenting more qualifying income, adding a co-borrower, putting more money down, or securing a lower interest rate. Each of these changes the math a lender uses to decide how large a loan your income will support, and some can add tens of thousands of dollars in borrowing power within a few weeks.
Pay Down Monthly Debt
Debt-to-income ratio is the single most influential number in your pre-approval. It compares your total monthly debt payments, including the projected mortgage, against your gross monthly income. Clearing debt off that ratio leaves more room for a larger mortgage payment, which is what expands the loan amount.1Fannie Mae. Debt-to-Income Ratios
The dollar effect is bigger than most borrowers expect. At current interest rates, every $100 in monthly debt payments you eliminate before applying frees up roughly $15,000 in additional borrowing power. Pay off a $350 car loan and your pre-approval can climb by more than $50,000 without any change to your income.
The debts that move the ratio fastest are the ones with the highest minimum payments relative to their balance: credit cards, auto loans, and personal loans. A few practical moves before you apply:
- Target revolving debt with high minimum payments first, not necessarily the debt with the highest balance.
- Don’t finance a car, furniture, or appliances in the months leading up to your application.
- Consolidate only when it actually lowers your total minimum monthly payment. A lower rate alone doesn’t help your DTI.
Student Loans on Income-Driven Repayment
Student loans are worth a closer look because lenders don’t all treat them the same way. For conventional loans backed by Fannie Mae, the lender uses the payment shown on your credit report, even if that payment is $0 under an income-driven repayment plan.2Fannie Mae. Top Trending Selling FAQs Other programs calculate 0.5% or 1% of your outstanding balance as an assumed monthly payment, which can inflate your DTI dramatically. If your current lender uses the higher method, shopping to one that follows Fannie Mae’s rule can lift your pre-approval without changing anything about your finances.
Raise Your Credit Score
Your score sets your interest rate, and your rate sets how much loan each dollar of monthly payment can support. A score of 740 or above generally qualifies you for the best conventional rates, and 760 or higher unlocks the most favorable terms available. A conventional loan generally requires a minimum score of 620.3Experian. Average Mortgage Rates by Credit Score Moving from the low 600s into the mid-700s doesn’t just cut your rate; it enlarges the loan your DTI can absorb.
Steps that tend to move a score fastest:
- Pay down credit card balances below 30% of each card’s limit, and below 10% if you can. Utilization is one of the largest score inputs.
- Make every payment on time. Payment history carries the most weight, and a single missed payment can drop a score meaningfully.
- Avoid opening new accounts before you apply. New inquiries and new accounts lower your average account age.
- Pull your reports from all three bureaus and dispute inaccuracies. Wrong late payments or accounts that aren’t yours drag your score down for no reason.
Rapid Rescoring
If you’ve just paid off a debt or corrected a report error, ask your lender about rapid rescoring. It updates your credit file with the bureaus in two to five days rather than the 30 to 60 days creditors normally take.4Experian. What Is a Rapid Rescore Your lender initiates it; you can’t request it yourself. Bring documentation of the change, such as a payoff letter or updated statement. If the new score pushes you into a higher pricing tier, the lender can recalculate your pre-approval right away.
Document More Qualifying Income
Every dollar of verifiable income raises the mortgage payment a lender will approve. Beyond base salary, several other income sources can count, but only if you can prove they’re stable and likely to continue. Fannie Mae generally looks for two years of history on variable income like bonuses, overtime, and commissions, though 12 to 24 months may qualify when other factors support it.5Fannie Mae.

- Court-ordered alimony or child support expected to continue at least three more years.5Fannie Mae. General Income Information

Asset Depletion Income
If you have substantial liquid assets in savings, investments, or certain retirement accounts, some lenders can convert those assets into qualifying monthly income even if you aren’t drawing from them. Under Freddie Mac guidelines, the lender subtracts your down payment and closing costs from your eligible assets and divides the remainder by 240 to produce a monthly figure that gets added to your other income for DTI.7Freddie Mac. Assets as a Basis for Repayment of Obligations With $600,000 in eligible assets after down payment and closing, that calculation adds $2,500 per month to your qualifying income, which can lift a pre-approval by $40,000 or more.
Add a Co-Borrower
Bringing another person onto the application adds their income to the DTI calculation and can meaningfully increase what a lender will approve. A co-borrower takes title, shares the obligation to pay, and is fully underwritten. A co-signer takes legal responsibility for the debt but doesn’t hold an ownership interest and isn’t on the deed.8U.S. Department of Housing and Urban Development. What Are the Guidelines for Co-Borrowers and Co-Signers
If your co-borrower won’t live in the home, stricter rules apply. For manually underwritten conventional loans with a non-occupant co-borrower, the occupying borrower’s DTI alone can’t exceed 43%, and the maximum LTV is capped at 90%. Automated underwriting is more flexible, allowing LTV up to 95% and evaluating all borrowers’ financial profiles together.9Fannie Mae. Guarantors, Co-Signers, or Non-Occupant Borrowers on the Subject Transaction
One caution: a co-borrower’s existing debts also enter the combined DTI. If they carry significant debts of their own, the boost from their income can be partially or fully offset. Review both financial pictures together before deciding this will actually raise the number.
Increase Your Down Payment
A larger down payment helps in two ways. It lowers your loan-to-value ratio, reducing the lender’s risk and often unlocking better terms. And putting at least 20% down eliminates private mortgage insurance, which typically runs $30 to $70 per month for every $100,000 borrowed.10Freddie Mac. Breaking Down Private Mortgage Insurance (PMI) Removing PMI frees room in your monthly budget for a larger principal-and-interest payment, which is what expands the approved loan amount.
Even short of 20%, every added dollar helps. The total price you can afford is the approved loan amount plus your down payment, so growing either side raises the ceiling on the homes you can consider.
Using Gift Funds
You don’t have to save the whole down payment yourself. Most loan programs allow gift funds from family, and some accept gifts from employers, close friends with a documented relationship, charitable organizations, or government homeownership programs. For FHA loans, gift funds can cover the full 3.5% minimum, provided the money is a genuine gift with no expectation of repayment.11U.S. Department of Housing and Urban Development. What Costs Can a Seller or Other Interested Party Pay on Behalf of the Borrower
Documentation matters. Your lender will want a signed gift letter confirming the money isn’t a loan, plus bank statements showing the transfer from the donor’s account to yours. If the funds are already deposited, the lender will want the donor’s statement showing the withdrawal alongside evidence of the deposit. Get this organized before you apply.
Shop for a Lower Interest Rate
Your rate controls how much loan each dollar of monthly payment can support. Dropping from 7.25% to 6.5% saves roughly $200 per month on a $400,000 loan, according to the Consumer Financial Protection Bureau.12Consumer Financial Protection Bureau. Data Spotlight: The Impact of Changing Mortgage Interest Rates That $200 in freed monthly capacity translates to about $30,000 more in borrowing power.
- Get three to five quotes from different lenders on the same day. Spreads are often wider than borrowers expect.
- Consider discount points. Paying about 1% of the loan amount typically buys down your rate by 0.25%, and the lender can then recalculate your pre-approval at the lower rate.
- If rates are falling, waiting briefly to lock can help. If they’re rising, locking sooner protects the number you already qualify for.
Switch to a Loan Program With Room
Different loan programs allow different maximum DTIs, and moving between them can raise your pre-approval without changing anything about your finances. Conventional loans through Fannie Mae’s automated underwriting allow up to 50% back-end DTI.1Fannie Mae. Debt-to-Income Ratios Manually underwritten conventional loans face stricter limits, often 36% to 43%. FHA loans also allow DTI ratios up to 50% or higher when compensating factors like strong reserves are present. VA loans don’t set a hard DTI cap; they apply a residual income test, and approvals above 50% are common when residual income is sufficient, though lenders typically apply extra scrutiny above 41%.
If DTI is your ceiling and you’re eligible, moving from a conventional loan to an FHA or VA loan can be the fastest way to a larger number.
Watch the Conforming Loan Limit
Even when income and credit support a large loan, conforming loan limits cap how much you can borrow through a conventional mortgage backed by Fannie Mae or Freddie Mac. For 2026, the limit is $832,750 for a single-family home in most areas and up to $1,249,125 in designated high-cost areas.13Federal Housing Finance Agency. FHFA Announces Conforming Loan Limit Values for 2026 Above those, you’re in jumbo territory, which generally requires a higher score, larger down payment, and lower DTI. FHA and VA loans have their own county-by-county limits. If your pre-approval sits near a program ceiling, a program with higher limits in your county, or a larger down payment to bridge the gap, is often the cleanest fix.
Refresh an Expiring Pre-Approval
Pre-approvals typically expire in 60 to 90 days. If your finances have improved during that window through debt paydown, a raise, or a higher score, renewing produces a higher approved amount. A drop in market rates since your original letter works the same way, because a lower rate lets the same monthly payment support a larger loan. When your letter is close to expiring and any of those things have moved in your favor, ask for a fresh pre-approval rather than just extending the old one.
