Conventional vs FHA vs VA vs Non-QM — on the Same Income
Same income, same debts, four different loan programs. The right program is the one with the right ceiling for your file. The biggest mistake first-time buyers make is shopping the wrong program first.

Down Payment: 3% vs 5% vs 10% vs 20%
Same buyer, four down-payment tiers. The right tier balances cash preservation against monthly payment — and against PMI, which drops off at 20% on conventional loans but stays for the life of an FHA loan.
Don't have 20%? You don't need to. Most first-time buyers close with 3-10% down, and many qualify for state down payment assistance (see below).
What First-Time Buyers Forget to Budget For
Your mortgage payment is the headline number. These are the line items that quietly turn "I can afford this" into "I can't sleep." Plan for them up front.
Closing Costs
Lender fees, title, appraisal, escrow, prepaid taxes and insurance. They're real, they're owed at closing, and they're separate from your down payment.
Moving + First-Month Setup
Movers, deposits, utility hookups, basic furniture, window coverings, kitchen essentials. The "after the keys" bills land fast.
Repair + Maintenance Reserve
HVAC, water heater, roof, plumbing, the surprise tree. Industry rule of thumb: budget 1% of the home's value every year, even if you don't spend it.
Property Tax Reassessment
In states without Prop 13 (everywhere except California), property tax can be reassessed annually. Budget for 5-10% growth a year in non-California states.
HOA Dues + Special Assessments
Condos and master-planned communities charge $200-$800/month standard, plus occasional special assessments for roofs, paint, pools. Ask for the reserve study.
Insurance Premium Drift
Especially in California (wildfire) and Florida (hurricane), home insurance can jump 20-40% at renewal. Quote with a real carrier before locking your max-house number.
DTI Ceilings by Loan Program
Three programs cover the vast majority of first-time buyer files. Each one has a different ceiling — which means the same income produces a different max house depending on the loan.
Conventional
- Front-end
- Not strictly enforced. 28% is the traditional benchmark.
- Back-end
- 36% normal; 45% with strong credit/reserves; 50% under Fannie Mae's Desktop Underwriter (DU).
DU's 50% ceiling is the lever for higher-priced files. Requires 700+ FICO, 6-12 months of reserves, low LTV.
FHA
- Front-end
- 31% officially.
- Back-end
- 43% officially. TOTAL Scorecard approves 50-57% with strong compensating factors.
FHA is the heaviest-used program for first-time buyers in affordable markets. 3.5% down with 580+ FICO.
VA
- Front-end
- None. VA does not consider front-end ratio.
- Back-end
- 41% preferred; 50%+ routine when residual income exceeds VA standard by 20%.
VA underwrites to residual income, not DTI. Eligible veterans frequently afford 15-25% more house than the same income on conventional.
Non-QM
- Income docs
- Bank statements, P&L only, DSCR (investor), asset-depletion, ITIN, foreign national.
- Back-end
- Typically 50% with strong credit; some programs to 55%.
For self-employed, RSU-heavy, multi-property, or recently relocated borrowers whose income doesn't fit a vanilla W-2 box.
Down Payment Assistance — Programs by State
Most first-time buyers don't need 20% down. Many qualify for state DPA programs that cover all or part of the down payment, often as a forgivable second loan. Programs change — ask us which fits your state and scenario.
Eligibility for each program depends on income limits, home price limits, FICO, occupancy, and county. We screen your file against every DPA program available in your state when we shop your loan.
Affordability FAQ
How accurate is this calculator vs an actual pre-approval?
This calculator uses the same DTI math a real underwriter uses, with state-specific tax and insurance defaults. The number it returns is a strong directional estimate — usually within 5-10% of what a wholesale underwriter will approve. Three things move the real number: your actual credit score and tradelines, the actual property's tax and HOA, and the lender's overlay on top of the program guideline. A real pre-approval pulls your credit and verifies income, which can push the number up or down. The honest answer: trust this for shopping; get a written pre-approval before you offer.
Why is the max home price different for Conventional vs FHA vs VA on the same income?
Different DTI ceilings. Fannie Mae caps DU at 50% back-end. FHA's automated underwriting (TOTAL Scorecard) can approve up to 57% with strong compensating factors. VA underwrites primarily to residual income and routinely approves 50%+ back-end DTI. On the same income, the program with the higher ceiling produces the higher max house price — assuming your file fits the program's other rules (FICO, occupancy, property type).
What's the difference between front-end and back-end DTI?
Front-end DTI is your housing payment (PITI plus HOA and MI) divided by gross monthly income. Back-end DTI adds all other monthly debt: car payments, student loans, credit-card minimums, child support, alimony. Front-end is what your home costs. Back-end is what your home plus your existing debt costs. Conventional Conventional and Non-QM programs don't strictly enforce a front-end limit. FHA officially caps front-end at 31%. Either way, back-end is the binding constraint for almost every file.
Can I afford a $500,000 house?
You need roughly $145,000-$160,000 in gross annual income with 10% down, current rates, no other debts. The exact number depends on your state (property tax + insurance), your loan program, and your existing monthly debts. Use the calculator above with your real numbers. For most U.S. states, the answer sits in that income range. In high-property-tax states (TX, NH, NJ), shift the floor up; in low-tax states (CO, ID, AL), shift it down.
What income do I need to buy a $300,000 house?
Roughly $85,000-$100,000 gross income with 10% down, depending on state taxes, insurance, and your other debts. With 20% down and no other monthly debts, you can stretch into the high-$70Ks. The calculator above will give you a state-tuned number in 5 seconds.
Should I use the FHA loan with the higher DTI ceiling?
Sometimes. FHA's 57% DTI ceiling is a real advantage when your DTI runs hot relative to your income. The cost: FHA charges a 1.75% upfront MIP financed into the loan, plus monthly MIP for the life of the loan (vs conventional PMI that drops off at 20% equity). If you can qualify on conventional at 45-50% DTI, conventional is usually cheaper over the long run. If you can't, FHA opens the door — and you can refinance to conventional once you build equity.
Why does the calculator say I can afford less than Zillow or NerdWallet?
National calculators use national-average assumptions: 1.0% property tax (most states are higher), 0.35% insurance (way too low for California, Florida, Texas), and they ignore PMI on under-20% down payments. They also don't apply the program-specific DTI ceiling. Our calculator runs state-tuned tax and insurance, applies the real program ceiling, and includes PMI/MIP automatically. The number you see here is closer to what a real lender will approve.
I'm self-employed. Can I still qualify?
Yes. Self-employed borrowers have three paths: (1) Conventional/FHA/VA using 2 years of tax returns and IRS Schedule C/K-1 income. The challenge is that legitimate business write-offs reduce qualifying income. (2) Bank statement loans (Non-QM) using 12-24 months of business or personal bank statement deposits as income proof. (3) DSCR loans for investment properties — qualifies on the property's rental income, not your personal income. The right path depends on how your tax returns look and what you're buying.
What's the difference between this calculator and getting pre-approved?
This calculator gives you an estimate based on what you enter. A pre-approval is a real underwriter reviewing your real W-2s, tax returns, credit pull, assets, and debts — then issuing a written letter that listing agents will read before they read your offer. In a seller's market, a pre-qualification letter (which is basically what a calculator produces) often gets your offer thrown out. Pre-approval takes 24-72 hours with us once we have your documents.
How long does a pre-approval take with OnPoint?
24-72 hours from receipt of complete documents (W-2s, tax returns, pay stubs, bank statements, ID). We pull your file against 20+ wholesale lenders and bring you the side-by-side comparison — rate, points, fees, monthly payment. You see who wins for your scenario before you commit to a lender. Most other brokers send your file to their one or two preferred lenders. We name the lenders. We send the comparison sheet. That's the work.
