Yes, you can get a mortgage with one income. Lenders approve solo applicants every day; what they care about is your credit score, your debt-to-income ratio, and whether you can document stable earnings. The math simply runs tighter than it does for two-earner households, because one paycheck has to carry the whole qualification.
What Approval Actually Hinges On
Three things decide a single-income application. Your credit score sets which loan programs you can even access and shapes the rate you’ll pay. Your debt-to-income ratio determines how much house that income can carry. And your documentation (pay stubs, tax returns, bank statements) has to line up cleanly, because there’s no second applicant whose numbers can offset a weak spot in yours.
The practical move before applying is to look at each of those three honestly. A score close to a threshold, a car payment that’s about to be paid off, a student loan servicer who can confirm your actual monthly payment: small moves on any of these can shift what you qualify for.
Credit Score Minimums by Loan Type
Different programs set different floors. Conventional loans sold through Fannie Mae require a minimum of 620 for manually underwritten loans, though individual lenders often set their own cutoff at 660 or higher.1Fannie Mae. General Requirements for Credit Scores FHA loans accept a 580 score with a 3.5 percent down payment, and scores between 500 and 579 still qualify if you can put 10 percent down. The Department of Veterans Affairs sets no official minimum for VA loans, though most lenders impose their own floor near 620.
Your score also drives your interest rate, and the gap matters. A borrower at 620 might pay roughly half a percentage point more than someone at 740 on the same loan. Over 30 years that’s tens of thousands of dollars. If your score sits just under a threshold, a few months of paying down credit card balances before applying can meaningfully change the economics.
How Debt-to-Income Ratios Shape Your Borrowing Power
Debt-to-income ratio is where single-income applications get tight. Lenders compare your total monthly debt payments, including the proposed mortgage, against your gross monthly income. With one earner, the income side of that fraction is smaller, so every existing payment eats a bigger share of your capacity.
The allowable ratios vary by program:
- Conventional loans run through Fannie Mae’s Desktop Underwriter can be approved with a DTI up to 50 percent. Manually underwritten conventional loans cap at 36 percent, rising to 45 percent with strong credit and cash reserves.2Fannie Mae. Debt-to-Income Ratios
- FHA sets a standard maximum of 43 percent, with ratios approaching 50 percent allowed for borrowers with compensating factors like substantial savings.
- VA guidelines point to 41 percent, and VA loans also apply a residual income test: after taxes, the mortgage, and all other debts, you need enough left each month to cover basic living expenses. The required cushion varies by region and family size.
The math is simple. Take your gross monthly income, multiply by the allowed DTI, subtract your existing monthly debts (car payments, student loans, minimum credit card payments). What’s left is the maximum payment you can carry for principal, interest, taxes, and insurance. A single earner making $6,000 per month with $500 in existing debts could carry up to $2,500 at a 50 percent DTI, but only $1,660 at a 36 percent manual-underwrite limit. The program you qualify for changes your buying power considerably.
Student Loans and Phantom Payments
Student loans trip up more single-income borrowers than almost anything else, particularly when an income-driven repayment plan shows $0 per month on the credit report. Lenders won’t accept zero. They impute a payment instead, and the method differs by loan type.
FHA rules require lenders to calculate 0.5 percent of the outstanding loan balance as your monthly payment when the credit report shows zero.3U.S. Department of Housing and Urban Development. Mortgagee Letter 2021-13 A $40,000 balance becomes a $200 monthly debt for DTI purposes. Fannie Mae uses 1 percent of the balance when no payment appears, turning that same $40,000 into a $400 monthly hit. On one income, that phantom payment can shave $50,000 or more off your qualifying loan amount.
If you can document an actual payment from your servicer, some programs will use that figure instead. Before you apply, get your loan servicer to send a letter or statement showing your current monthly payment. For borrowers with large balances and low income-driven payments, this one step can decide whether you qualify at all.
Income That Isn’t a Paycheck
A mortgage application doesn’t require that your income come from a salary. Alimony, child support, Social Security, disability benefits, retirement distributions, and investment income all count, provided you can prove they’re stable and will continue.
For alimony and child support, Fannie Mae requires a minimum six-month history of full, regular, and timely payments, and the income must be expected to continue for at least three years from the date of the mortgage note.4Fannie Mae. Alimony, Child Support, Equalization Payments, or Separate Maintenance If your youngest child ages out of support in two years, that payment won’t count. Lenders look at the ages of the children and the terms of the court order to decide.
Social Security and disability income follow a different rule. Unless the benefit verification letter specifically states that payments expire within three years of the loan, lenders should treat them as continuing.5Consumer Financial Protection Bureau. Social Security Disability Income Shouldn’t Mean You Don’t Qualify for a Mortgage Lenders cannot ask about the nature of your disability or require a doctor’s statement. If a loan officer presses for that, they’re overstepping federal guidance.
If You’re Self-Employed
Self-employed solo borrowers face extra documentation. Fannie Mae requires two years of signed personal federal tax returns to establish an earnings history.6Fannie Mae. Underwriting Factors and Documentation for a Self-Employed Borrower Business returns (Schedules K-1, Form 1120, or 1120S) are typically required, along with a year-to-date profit and loss statement.
Here’s the part that surprises people: the income lenders use is your net income after business deductions, not your gross revenue. Aggressive write-offs can shrink the number lenders will qualify. They average the two most recent years of net income, and if year two came in lower than year one, they use the lower year rather than the average. If you’re planning a purchase a year or two out, think carefully about how much you deduct before filing.
Low Down Payment Programs
Saving the down payment is often the hardest part on one income. Several programs target this directly.
Fannie Mae’s HomeReady program allows down payments as low as 3 percent and is available when total annual qualifying income doesn’t exceed 80 percent of the area median income for the property’s location.7Fannie Mae. HomeReady Mortgage Loan and Borrower Eligibility Freddie Mac’s Home Possible offers similar terms with a 3 percent minimum on one-unit properties.8Freddie Mac Single-Family. Home Possible Both allow the entire down payment to come from gift funds, grants, or community assistance programs, which matters when there’s no second earner helping you save.
FHA loans remain the most accessible for lower credit scores, requiring just 3.5 percent down with a 580 score. VA loans require no down payment at all for eligible service members and veterans. USDA loans offer zero-down financing in designated rural areas, subject to income limits. For a single earner, the right program can cut the upfront cash need from tens of thousands to a few thousand.
If any of your down payment comes from a gift, the donor must provide a signed letter confirming the money doesn’t need to be repaid, along with proof of the transfer. Eligible donors include relatives by blood, marriage, or adoption, domestic partners, fiancés, and people with a long-standing close relationship to you. The donor cannot be affiliated with the builder, developer, or real estate agent in the transaction.9Fannie Mae. Personal Gifts
Private Mortgage Insurance and How It Ends
Any conventional loan with less than 20 percent down requires private mortgage insurance. PMI protects the lender, not you, and it adds a real amount to your monthly payment. On one income, that extra cost pinches harder.
PMI isn’t permanent on a conventional loan. You can request cancellation once your loan balance drops to 80 percent of the home’s original value, and your servicer must automatically terminate it when the balance hits 78 percent.10Consumer Financial Protection Bureau. When Can I Remove Private Mortgage Insurance (PMI) From My Loan? “Original value” means the purchase price or the appraised value when you bought, whichever is lower. Automatic termination doesn’t require a new appraisal, though some servicers will accept one to speed things up if your home has appreciated.
FHA works differently. FHA mortgage insurance premiums last the life of the loan if you put less than 10 percent down. With 10 percent or more down, FHA insurance drops off after 11 years. That’s one reason a single-income buyer who can clear a 620 credit score often benefits from a conventional loan, even though FHA’s DTI limits are more generous.
Employment History and Gaps
Lenders want a two-year history of stable employment, ideally in the same field. The logic is simple: consistent earnings predict future earnings. They verify your employment by contacting current and past employers directly.
Gaps don’t automatically disqualify you, but they invite scrutiny. A break of six months or more typically requires a written explanation and evidence you’ve been back to work with steady income for several consecutive months. Career changes within the same industry are usually fine. A complete pivot combined with thin reserves and a high DTI can stall an application. If a gap is on your resume, get ahead of it with a brief letter explaining what happened and what’s changed, and bring it to your first meeting with the loan officer.
Reserves After Closing
Some single-income buyers worry about having to show a big balance left over after closing. For a standard one-unit primary residence run through Fannie Mae’s automated underwriting, there is no minimum reserve requirement.11Fannie Mae. Minimum Reserve Requirements That’s genuine good news for solo buyers stretching to afford a first home.
The requirements tighten for other property types. A second home requires two months of mortgage payments in liquid reserves. Two- to four-unit properties or investment properties require six months. Manually underwritten loans carry their own reserve requirements, which can be more demanding. Even when reserves aren’t formally required, keeping two to three months of payments saved gives you a real safety net. On one income, a single car repair or medical bill in your first months of ownership can create serious stress without that cushion.
