Here's a misconception I hear constantly in my practice: "I can't get a conventional loan — my credit isn't perfect" or "conventional loans require 20% down."
Both statements are wrong. And they've cost borrowers real money — by steering them toward FHA loans when a conventional loan would have been cheaper over the life of their mortgage.
Conventional loans are available with credit scores as low as 620 and down payments as low as 3% through Fannie Mae's HomeReady program. The 20% threshold isn't a requirement — it's the point at which PMI disappears. That's a meaningful distinction.
Let me give you the actual picture.
What "Conventional" Actually Means
A conventional loan is any residential mortgage that isn't guaranteed or insured by a federal agency. No FHA, no VA, no USDA backing. The lender takes on the credit risk directly, or offloads it to the secondary market by selling the loan to Fannie Mae or Freddie Mac.
Fannie Mae and Freddie Mac — the government-sponsored enterprises created by Congress to support the U.S. housing market — are what make the conventional loan ecosystem function. They buy mortgages from lenders, package them into mortgage-backed securities, and provide liquidity that keeps mortgage rates lower than they'd otherwise be. The "guidelines" for conventional loans are essentially the standards Fannie and Freddie will accept when purchasing loans from originators.
This is why conventional loans are so standardized: they're written to be sellable on the secondary market.
Conforming vs. Non-Conforming: The Line That Changes Everything
All conventional loans split into two categories based on loan amount:
Conforming loans fall at or below the FHFA's annual conforming loan limit. For 2026, FHFA announced the baseline limit at $832,750 for single-unit properties in most of the country — up $26,250 from $806,500 in 2025, reflecting a 3.26% increase in average U.S. home prices between Q3 2024 and Q3 2025. In designated high-cost areas (coastal California, New York City, Hawaii, Alaska), the ceiling rises to $1,249,125 for one-unit properties.
Multi-unit property limits for 2026: | Property Type | Baseline Limit | High-Cost Limit | |--------------|---------------|-----------------| | 1-unit | $832,750 | $1,249,125 | | 2-unit | $1,032,650 | $1,548,975 | | 3-unit | $1,248,150 | $1,872,225 | | 4-unit | $1,551,250 | $2,326,875 |
Conforming loans are eligible for purchase by Fannie Mae and Freddie Mac. That secondary market guarantee keeps conforming rates competitive.
Non-conforming (jumbo) loans exceed the conforming limit. Because lenders can't sell these to Fannie or Freddie, they hold them on their own books or sell to private investors — creating additional risk that translates to higher rates and stricter requirements. Expect 0.25–0.75% higher rates, 700+ credit, and 20% minimum down on most jumbo products.
The Real Credit Score Picture
The minimum credit score for a conventional loan is 620 under Fannie Mae and Freddie Mac guidelines. Full stop. But what "qualifies" and what "qualifies at competitive pricing" are different things entirely.
Conventional loan pricing is driven by Loan-Level Price Adjustments (LLPAs) — a grid of rate premiums Fannie Mae and Freddie Mac publish that vary by credit score and loan-to-value. The better your score and the lower your LTV, the fewer adjustments layered into your rate.
Per FHFA's 2025 data, the average credit score for closed conventional loan borrowers was 753. That's the median successful borrower — well above the 620 floor. Here's why: at 620, the LLPAs stack up enough that FHA often produces a lower rate despite its permanent mortgage insurance. The competitive sweet spot for conventional is typically 680 and above, with the best pricing tier activating at 760+.
Improving your score from 679 to 680, or from 719 to 720, can cross pricing tier thresholds worth 0.125–0.25% in rate. On a $350,000 loan, that's $7,000–14,000 over 30 years. Checking your score with sufficient lead time to improve before applying is one of the highest-ROI moves available to borrowers.
Down Payment Requirements
Conventional loans do not require 20% down. Here's the actual structure:
- **3% down:** Available for first-time buyers through Fannie Mae HomeReady and Freddie Mac Home Possible. Income limits apply in some cases.
- **5% down:** Standard minimum for repeat buyers on single-family homes
- **10% down:** Typical minimum for second homes; also available for primary residences
- **15%+ down:** Reduces PMI rate significantly; 20% eliminates PMI entirely
- **20%+ down:** No PMI required on conventional loans
The 20% down myth persists because it's where PMI disappears — not where the loan becomes available. Below 20% down, you pay PMI; the question is whether PMI costs more or less than the mortgage insurance on alternative loan types.

Private mortgage insurance protects the lender — not you — if you default. It's required on conventional loans with less than 20% down, and its cost depends on your credit score, down payment, and the PMI insurer.
Annual PMI cost range: 0.25–2.0% of the loan amount. On a $300,000 loan, that's $60–500/month. At 10% down with a 720 credit score, expect roughly 0.5–0.7% annually — about $125–175/month. At 5% down with a 660 score, expect closer to 1.2–1.5% — around $300–375/month.
The key advantage over FHA: Conventional PMI is cancellable.
- **At 80% LTV** (based on original purchase price): You can request PMI cancellation in writing. The lender may order an appraisal to verify value.
- **At 78% LTV** (based on original purchase price): The Homeowners Protection Act requires automatic PMI cancellation. No request needed.
- **Via refinancing:** If your home has appreciated significantly, refinancing with a new appraisal that demonstrates 20%+ equity eliminates PMI — though you incur new closing costs.
FHA mortgage insurance, by contrast, lasts for the life of most FHA loans originated today. That permanent insurance is why borrowers with 700+ credit who stay in the home long-term almost always pay less with a conventional loan — even with PMI in the early years. Use the PMI calculator to see how long you'd pay PMI and compare total costs across loan types.
Conventional vs. FHA vs. VA: Full Comparison
| Feature | Conventional | FHA | VA | |---------|-------------|-----|-----| | Minimum credit score | 620 | 580 (3.5% down) / 500 (10% down) | No official minimum (~620 lender standard) | | Minimum down payment | 3–5% | 3.5% | 0% | | Mortgage insurance | PMI — cancellable at 20% equity | MIP — life of loan (most cases) | No PMI (funding fee applies once) | | 2026 loan limit | $832,750 | $832,750 | No loan limit | | Max DTI (guideline) | ~45% | ~56.9% | Residual income standard | | Eligible property types | Primary, second home, investment | Primary residence only | Primary residence only | | Who qualifies | Any eligible borrower | Any eligible borrower | Veterans, active duty, eligible spouses | | Best suited for | 700+ credit, 5–20% down, long-term hold | Sub-680 credit, minimal down payment | VA-eligible borrowers — almost always wins |
One important note on that last row: if you're VA-eligible, run a comparison before defaulting to conventional. Per Freddie Mac data, VA loan rates typically run 0.25–0.50% below conventional, and the elimination of PMI saves most VA borrowers $100–300/month. The math almost always favors VA. See the VA loan guide.
Debt-to-Income Ratio Requirements
Conventional guidelines allow a back-end DTI (all debts plus housing) of up to 45% — some lenders stretch to 50% with compensating factors like strong credit or significant reserves. The front-end DTI (housing costs alone) is typically expected below 28%.
In practice, the cleanest approvals happen below 36% back-end DTI. Above 43%, you'll need compensating factors — high credit score, substantial savings, stable long-term employment — and the lender's automated underwriting system becomes less forgiving.
Use the DTI calculator before applying to confirm where you stand. DTI surprises in underwriting are the most common source of last-minute complications.
Income Documentation Requirements
W-2 employees: Two years of W-2s and federal tax returns, plus 30 days of current pay stubs. Lenders use the most recent 2-year average of base salary (not bonuses or overtime, unless those are documented as consistent and likely to continue).
Self-employed borrowers: Two years of personal and business federal tax returns, a year-to-date profit-and-loss statement (often CPA-prepared), and business bank statements. Qualifying income is based on net income after business deductions — aggressive deduction strategies that minimize tax liability also minimize qualifying income.
Commission and variable income: Averaged over 2 years. If you're in a commission-heavy role, apply when your 2-year average is strong — not immediately after a down year.
When a Conventional Loan Is the Right Choice
Choose conventional when: - Credit score is 700 or above — you'll hit competitive pricing tiers - Down payment is 5–20% — PMI eventually cancels, unlike FHA MIP - You're buying a second home or investment property — FHA and VA require primary occupancy - The property has characteristics that FHA appraisal standards might reject — older homes, smaller square footage, rural locations with few comparables - You plan to stay 5+ years — enough time for PMI to cancel and for the rate advantage of conventional to compound over FHA's lifetime MIP
Choose FHA instead when: - Credit is below 680 and FHA produces a meaningfully lower rate - Past credit events (bankruptcy, foreclosure) are within the waiting period - DTI is above 43% without compensating factors - Down payment is minimal and the conventional PMI rate would be prohibitive
If you're genuinely on the fence between FHA and conventional, the refinancing guide covers a path many borrowers use: start with FHA to get into homeownership, then refinance into conventional once you've built 20% equity and improved your credit profile.
Frequently Asked Questions
What is a conventional loan in simple terms?
A conventional loan is a mortgage not backed by a government agency like FHA, VA, or USDA. It follows guidelines set by Fannie Mae and Freddie Mac, which purchase these loans from lenders on the secondary market. Most conventional loans are "conforming" — meaning they fall below FHFA's annual loan limit ($832,750 for 2026 in most areas) and meet Fannie and Freddie's eligibility standards for income, credit, and property type.
What credit score do I need for a conventional loan?
The technical minimum is 620 under Fannie Mae and Freddie Mac guidelines. However, per FHFA data, the average credit score for approved conventional borrowers was 753 in 2025. At 620, pricing adjustments increase your effective rate significantly. Borrowers below 680 should compare conventional versus FHA carefully — FHA sometimes produces a lower rate despite its permanent mortgage insurance, depending on the specific credit score and down payment combination.
How much do I need to put down on a conventional loan?
First-time buyers can qualify for as little as 3% down through Fannie Mae's HomeReady or Freddie Mac's Home Possible programs. Repeat buyers typically need 5% minimum. Below 20% down requires PMI, which runs 0.25–2.0% annually based on credit score and LTV. The PMI cancels automatically at 78% LTV — unlike FHA mortgage insurance, which lasts the life of most loans.
What is the 2026 conforming loan limit?
FHFA announced the 2026 baseline conforming loan limit at $832,750 for single-family properties in most U.S. counties — a $26,250 increase from the 2025 limit of $806,500, reflecting 3.26% home price appreciation. High-cost area limits reach $1,249,125. Loans above these thresholds are considered jumbo loans and face stricter requirements and higher rates.
Is a conventional loan better than FHA?
For borrowers with 700+ credit and 5–10% down who plan to stay in the home 5+ years, conventional is usually better — PMI eventually cancels, while FHA MIP does not. For borrowers with sub-680 credit, minimal down payment, or high DTI ratios, FHA often produces a lower total cost. The break-even calculation depends on your specific rate difference and how long you'll hold the loan before either selling or reaching 20% equity.
Can I get a conventional loan for a rental property?
Yes. Conventional loans allow investment property purchases — something FHA and VA loans do not permit (both require owner-occupancy). However, investment properties carry additional loan-level price adjustments: expect rates 0.5–0.875% higher than primary residence rates, a minimum 15–25% down payment depending on property type, and reserves requirements of 6 months of payments in liquid assets.

The conventional loan is the workhorse of American mortgage financing precisely because it's flexible — but that flexibility is structured around credit score and equity thresholds that meaningfully change your cost. Start by modeling your monthly payment at different loan amounts with the mortgage calculator, then use the affordability calculator to back-calculate a purchase price from your income and debts. If you're weighing conventional against FHA, the PMI calculator can show you exactly how long you'd pay mortgage insurance under each scenario and which structure produces lower lifetime costs for your specific numbers.
