Conventional loan requirements in 2026 come down to three numbers: your credit score, your down payment, and your debt-to-income ratio, and knowing where you land on each tells you what rate and monthly payment you’re actually shopping for. Most explainers stop at listing minimums. This one ties each requirement to a full monthly-cost worksheet and a side-by-side comparison against FHA and VA financing, then walks through the private mortgage insurance removal math that trips up more homeowners than any other part of the loan.
Minimum Credit Score, Down Payment, and DTI Thresholds for 2026
Duane Buziak, NMLS #1110647
Fannie Mae’s automated underwriting standards generally require a minimum 620 credit score for a standard conventional approval, a threshold confirmed in the Fannie Mae Selling Guide. Freddie Mac applies a comparable floor through its own automated underwriting system. Scoring above 620, sometimes well above it, matters because conventional pricing is risk-based: a 760 borrower and a 625 borrower can qualify for the identical loan amount yet land on materially different rates and PMI costs.
Down payment is where the biggest misconception lives. Twenty percent down is not a requirement, it’s a shortcut around mortgage insurance. Standard conventional financing allows as little as 5% down, and first-time buyers using Fannie Mae’s HomeReady or Freddie Mac’s Home Possible-style programs can qualify with 3% down, subject to income limits and property type restrictions. Lower down payments mean a higher loan-to-value ratio (LTV), which is simply your loan balance divided by the home’s value, and higher LTV typically means higher PMI and slightly higher pricing.
Debt-to-income ratio (DTI), your total monthly debt payments divided by your gross monthly income, has more flexibility than most buyers assume. Automated underwriting can approve borrowers up to roughly 45-50% DTI when compensating factors are strong: significant cash reserves, a higher credit score, or a lower LTV all help offset a higher DTI. This is exactly where a soft credit pull mortgage pre-approval earns its keep. Instead of guessing at your ratio or triggering a hard inquiry before you’ve compared a single lender, a no credit hit mortgage application lets you see your real DTI and credit tier first, then shop rate quotes against that actual number rather than an estimate.
The conforming loan limit, the maximum loan amount Fannie Mae and Freddie Mac will purchase, is set annually by the Federal Housing Finance Agency and adjusted for high-cost areas. Check the current FHFA baseline for your county before assuming a loan amount fits inside conventional limits, since anything above it moves into jumbo territory with its own credit and reserve requirements.
Total Cost of Ownership Worksheet: What a Conventional Loan Really Costs Each Month
Requirements only tell you whether you qualify. The worksheet below tells you what the loan actually costs. Suppose a $380,000 purchase price with 5% down, or $19,000, leaving a $361,000 loan balance. For illustration only, as of 2026, assume a 30-year fixed rate of 6.5% (APR will vary by lender, credit profile, and points paid, so treat this as a placeholder to build the math, not a quoted rate).
Principal and interest on $361,000 at 6.5% over 360 months works out to approximately $2,282 per month. Property tax is locality-specific; using the current rate published on the Mecklenburg County, North Carolina tax assessor’s page, a $380,000 home generates an annual tax bill that, divided across twelve months, typically adds several hundred dollars to the payment depending on the current millage rate posted at time of assessment. Homeowners insurance for a home in this price range commonly runs $100 to $175 per month depending on coverage and location. PMI on a 95% LTV conventional loan (5% down) typically falls in the 0.5% to 1.0% annual range depending on credit score, which on a $361,000 balance works out to roughly $150 to $300 per month.
Stack those together and a 5%-down buyer on this scenario is looking at principal and interest near $2,282, plus locality-specific taxes, plus insurance, plus PMI, landing the full monthly housing payment noticeably above the P&I figure alone. That gap is the part most rate quotes leave out.
Now shift the down payment. At 10% down ($38,000), the loan balance drops to $342,000, principal and interest falls to roughly $2,162 per month, and PMI, now priced against a 90% LTV, typically drops toward the lower end of the range, often $100 to $200 per month. At 20% down ($76,000), the loan balance is $304,000, principal and interest lands near $1,921 per month, and PMI disappears entirely because LTV falls to 80%. The swing from 5% down to 20% down isn’t just a smaller loan, it’s the complete removal of a monthly PMI line that can run $150 to $300 depending on credit and coverage. That’s the real dollar impact of down payment size, and it’s exactly the kind of comparison a soft-pull pre-approval lets you run against multiple wholesale lenders before you commit to one down payment strategy.
Conventional vs. FHA vs. VA: Comparing Requirements and Fees Side by Side
None of these three programs is universally “better.” Each fits a different credit profile, down payment reality, and long-term ownership plan, which is precisely why shopping all three side by side, rather than defaulting to whichever one your first lender pushes, tends to save the most money over the life of the loan.
| Program | Min Credit Score | Min Down Payment | Mortgage Insurance | Max Cash-Out LTV | Typical Closing Cost Range |
|---|---|---|---|---|---|
| Conventional | 620 | 3-5% | PMI, removable at 80% LTV | 90% | 2-5% of loan amount |
| FHA | 580 (3.5% down) | 3.5% | MIP, often life-of-loan | 80% | 2-5% of loan amount |
| VA | No agency-set minimum; lender overlays typically 580-620 | 0% | No monthly MI; VA funding fee applies | 100% | 1-4% of loan amount, funding fee often financed |
The cash-out figures deserve their own callout because they’re frequently confused. Conventional cash-out refinances cap at 90% LTV under current Fannie Mae and Freddie Mac guidelines, while VA cash-out refinances, per VA.gov’s cash-out refinance guidance, allow eligible veterans to refinance up to 100% of the home’s value. That 10-point spread matters if you’re pulling equity for renovations or debt consolidation and are deciding between programs.
FHA’s mortgage insurance premium (MIP) often lasts for the life of the loan when the down payment is under 10%, whereas conventional PMI is removable once you hit 80% LTV, a meaningful long-term difference even if FHA’s upfront credit requirements are more forgiving. This is where working with a broker who can shop hundreds of wholesale lenders across conventional, FHA, and VA simultaneously pays off: instead of applying separately to compare, you get a side-by-side quote sheet built around your actual credit and income profile in one pass, which is the entire premise behind “Don’t Guess Your Rate, Shop It.”
How PMI Removal Works on a Conventional Loan
PMI is not permanent on a conventional loan, and the rule that governs its end is federal law, not lender discretion. Under the Homeowners Protection Act of 1998, PMI automatically terminates once your loan balance reaches 78% of the home’s original value, and you can request removal yourself once you reach 80%, according to the Consumer Financial Protection Bureau. The distinction matters: automatic termination happens whether or not you ask, but requesting removal at 80% gets PMI off your payment sooner, provided your payment history is current.
Return to the earlier worksheet. On the $380,000 home with a $361,000 starting loan (95% LTV), 80% of the original $380,000 value is $304,000. Once amortization brings the loan balance down to $304,000, the borrower can submit a written request to the servicer to drop PMI, cutting that $150 to $300 monthly line entirely from the payment calculated in the section above. On a 30-year term at the illustrative 6.5% rate used earlier, reaching that balance from a $361,000 start takes several years of standard amortization, though extra principal payments accelerate the timeline.
There’s a faster path for homeowners in an appreciating market. If your home’s value has climbed since purchase, an updated appraisal can show you’ve crossed the 80% LTV threshold well ahead of the amortization schedule, even though your loan balance hasn’t dropped to $304,000 yet. Servicers generally require a “broker price opinion” or a full appraisal, at your expense, plus a track record of on-time payments, before honoring an early removal request based on appreciation rather than paydown. It’s worth checking annually if your local market has moved, since a $20,000 to $30,000 jump in value can shave a year or more off the wait.
Conventional Loan Requirements: 10 Common Questions Answered
What credit score do I need for a conventional loan in 2026? Fannie Mae and Freddie Mac generally set the floor at 620 for automated underwriting approval. Scores above that threshold typically unlock better pricing and lower PMI costs even at the same loan amount.
Can I get a conventional loan with 5% down? Yes, standard conventional financing allows 5% down, and first-time buyers using HomeReady or Home Possible-style programs can go as low as 3% down. The tradeoff is monthly PMI until you reach 80% LTV.
How is DTI calculated for a conventional mortgage? DTI is your total monthly debt payments, including the new mortgage, divided by your gross monthly income. Automated underwriting can approve DTI up to roughly 45-50% when compensating factors like reserves or a strong credit score offset the risk.
Does a soft credit pull mortgage pre-approval hurt my score? No, a soft pull does not generate a hard inquiry and has no impact on your credit score. It’s designed to let you see your real numbers before you shop rates or commit to an application.
When does PMI go away on a conventional loan? PMI automatically terminates at 78% of the home’s original value under the Homeowners Protection Act, and you can request removal yourself at 80%. An updated appraisal showing appreciation can sometimes speed that timeline up.
Is FHA always cheaper than conventional? Not necessarily. FHA mortgage insurance often lasts for the life of the loan, while conventional PMI is removable at 80% LTV, so a borrower with a strong credit score frequently pays less over time with conventional financing.
What’s the difference between conventional and VA cash-out refinance limits? Conventional cash-out refinances cap at 90% LTV under current Fannie Mae and Freddie Mac guidelines, while VA cash-out refinances allow eligible veterans up to 100% LTV per VA.gov guidance.
Do I need 20% down to avoid PMI entirely? Yes, on a conventional loan, 20% down (80% LTV) at closing avoids PMI from day one. Below that, PMI applies but is removable once your balance reaches 80% of the original value.
Can down payment assistance be combined with a conventional loan? Programs like Dynamo and Turbo DPA are structured to pair with conventional financing to help cover the down payment or closing costs, subject to program-specific income and eligibility guidelines. Eligibility varies by state and household income, so confirm current program terms before assuming qualification.
What’s a compensating factor in mortgage underwriting? A compensating factor is anything that offsets a weaker part of your file, such as large cash reserves, a low LTV, or a credit score well above the minimum. Underwriters weigh these factors together rather than judging DTI or credit score in isolation.
Shop the Rate Before You Shop the Program
Meeting the minimum credit score, down payment, and DTI thresholds only tells you that you qualify. It doesn’t tell you whether the specific rate, PMI structure, and closing costs a single lender quotes you are competitive, and that gap is where most of the real savings sit. The only way to know is to compare how different wholesale lenders price the identical conventional loan against your actual file.
