Conventional Loan Requirements 2026: Everything You Need to Qualify

Conventional loans are the most common mortgage in the United States — roughly two-thirds of all home purchases are financed with one. Yet many buyers assume they need a large down payment or perfect credit to qualify. In reality, conventional loans are available with as little as 3% down, and a significant change to Fannie Mae’s underwriting system in late 2025 means the old hard credit score floor no longer applies the way it once did.

This guide covers everything you need to know about conventional mortgage requirements in 2026 — from credit scores and down payments to conforming loan limits, PMI, and how loan pricing actually works.

What Is a Conventional Loan?

A conventional loan is any mortgage that is not backed or insured by a federal government agency. FHA loans are insured by the Federal Housing Administration, USDA loans are guaranteed by the Department of Agriculture, and VA loans are backed by the Department of Veterans Affairs. Conventional loans carry none of that government guarantee — they are originated by private lenders and funded by the private market.

Most conventional loans are also “conforming,” meaning they meet the underwriting guidelines established by Fannie Mae and Freddie Mac — the two government-sponsored enterprises (GSEs) that purchase mortgages from lenders on the secondary market. When your loan conforms to their standards, lenders can sell it to Fannie or Freddie, freeing up capital to make more loans. That process is what keeps conventional mortgage rates competitive and broadly available.

The absence of government backing means conventional loans have stricter baseline qualification requirements than FHA loans — but they also come without the lifetime mortgage insurance that FHA borrowers pay, and they can be used for primary residences, second homes, and investment properties alike.

Conforming vs. Non-Conforming Loans

Every conventional loan falls into one of two categories:

Conforming loans meet the dollar limits and underwriting standards set by the Federal Housing Finance Agency (FHFA) and purchased by Fannie Mae and Freddie Mac. Because lenders can sell these loans into the secondary market, they typically carry lower interest rates and more flexible terms than non-conforming alternatives. Most conventional mortgage borrowers take out conforming loans.

Non-conforming loans exceed the conforming limits (called jumbo loans) or don't meet Fannie/Freddie guidelines for other reasons. Jumbo loans require higher credit scores, larger down payments, stricter debt-to-income ratios, and often more cash reserves — and they generally price at slightly higher rates than conforming loans of similar size.

2026 Conventional Loan Limits

The Federal Housing Finance Agency raises conforming loan limits annually based on changes in national home prices. For 2026, the limits increased meaningfully from 2025 levels — giving buyers more borrowing power before crossing into jumbo territory.

Alaska, Hawaii, Guam, and the U.S. Virgin Islands receive 50% higher baseline limits than the standard floor. High-cost area designations are assigned by the FHFA based on local median home prices — use the FHFA's lookup tool to find the exact limit for your county.

The $832,750 standard limit represents a $26,250 increase over the 2025 limit of $806,500 — meaningful additional borrowing power for buyers in mid-priced markets who might otherwise have needed jumbo financing.

Credit Score Requirements

Conventional loan credit score requirements shifted significantly in late 2025. In November 2025, Fannie Mae updated its Desktop Underwriter (DU) automated underwriting system to no longer enforce a hard minimum credit score floor. Instead of a binary pass/fail at a set score, DU now evaluates the full borrower profile — income stability, assets, LTV, debt levels, and credit history depth — as a holistic picture.

In practice, most lenders still apply their own internal minimums of 620 as a starting point, and a score below 620 will face significant obstacles to approval. But the shift in Fannie Mae's approach means borrowers with non-traditional credit histories, thin files, or scores just below historic minimums may find more flexibility than they would have previously.

What hasn't changed: your credit score remains one of the most powerful factors in determining your interest rate. Conventional loans use a pricing system called Loan Level Price Adjustments (LLPAs) — covered in detail below — that directly ties your rate and fees to your credit score tier. The qualification bar may have softened slightly, but the pricing incentive to have the strongest credit possible remains as strong as ever.

Credit score tiers and their general impact on conventional loan pricing:

Understanding how your credit score affects your specific mortgage rate — and what you can do to improve it before applying — is one of the highest-ROI steps in the homebuying process. See our full guide on how your credit score affects your mortgage rate for a detailed breakdown.

Down Payment Requirements

Conventional loans offer more down payment flexibility than most buyers realize. The minimum varies based on the loan program and your profile:

• 3% down: Available through Fannie Mae's HomeReady and Freddie Mac's Home Possible programs for qualifying borrowers (income limits apply in most areas). Also available for some first-time buyers through standard Fannie Mae guidelines.
• 5% down: The standard minimum for most conventional loans on primary residences. Repeat buyers who don't qualify for 3% programs typically need at least 5%.
• 10% down: Required for second homes and vacation properties.
• 15–25% down: Required for investment properties, depending on the number of units.
• 20% down: The threshold that eliminates PMI entirely. Borrowers who can put down 20% avoid the monthly insurance cost and often access better LLPA pricing.

Down payment funds can come from personal savings, gift funds from a family member, or proceeds from the sale of another property. Unlike some FHA guidelines, conventional loans may require a minimum personal contribution depending on LTV and loan type. Seller concessions — where the seller pays a portion of your closing costs — are allowed up to 3% of the purchase price with less than 10% down, rising to 6% with 10–25% down and 9% with 25%+ down.

Debt-to-Income Ratio

Your debt-to-income ratio (DTI) compares your total monthly debt obligations to your gross monthly income. Conventional lenders evaluate two DTI ratios:

• Front-end DTI: Your proposed monthly housing payment (principal, interest, taxes, insurance, and HOA if applicable) as a percentage of gross monthly income. Most lenders prefer this below 28–36%.
• Back-end DTI: All monthly debt payments — housing plus car loans, student loans, credit cards, and other obligations — divided by gross monthly income. The standard conventional limit is 45%.

Fannie Mae's DU can approve back-end DTIs up to 50% for well-qualified borrowers with compensating factors — strong credit scores, significant liquid reserves, or low LTV ratios. In practice, lenders become more cautious above 43%, and borrowers with DTIs above 45% often find conventional approval challenging without strong offsets elsewhere in the file.

If your DTI is elevated, reducing it before applying — by paying down revolving balances or eliminating a car payment — can meaningfully improve both your approval odds and your pricing tier.

Private Mortgage Insurance (PMI)

Private mortgage insurance is required on conventional loans when your down payment is less than 20% of the home's purchase price. It protects the lender — not you — in the event of default, and its cost is passed to you as a monthly premium.

Conventional PMI rates typically range from 0.5% to 1.5% of the loan amount annually, depending primarily on your credit score and LTV ratio. A borrower with a 720 credit score and 5% down might pay approximately 0.65% annually — about $162/month on a $300,000 loan. A borrower with a 660 score at the same LTV might pay closer to 1.2%, or roughly $300/month on the same loan.

The critical advantage of conventional PMI over FHA mortgage insurance: it's removable. Under the federal Homeowners Protection Act, your lender must automatically cancel PMI when your loan balance reaches 78% of the original purchase price based on your scheduled payments. You can request cancellation earlier, at 80% LTV, if you've made payments on time and your home's value supports the equity — which may require a new appraisal.

This automatic cancellation right is one of conventional lending's most significant advantages over FHA loans, where mortgage insurance typically lasts the life of the loan for borrowers who put down less than 10%. On a $350,000 loan, that difference can amount to $40,000–$60,000 in lifetime mortgage insurance costs. For a full breakdown, see our guide to removing PMI.

How LLPA Pricing Affects Your Rate

Loan Level Price Adjustments — LLPAs — are risk-based pricing surcharges applied by Fannie Mae and Freddie Mac that directly affect the interest rate and fees you're offered on a conventional loan. Understanding them separates informed borrowers from those who are blindsided by their loan estimate.

LLPAs are expressed as a percentage of the loan amount and added to your closing costs or built into a slightly higher interest rate. They're triggered by risk factors including:

• Credit score: The lower your score, the higher the LLPA surcharge. Below 660, surcharges become significant.
• Loan-to-value ratio: Higher LTV (smaller down payment) triggers higher adjustments.
• Property type: Condos, manufactured homes, and investment properties carry higher LLPAs than single-family primary residences.
• Loan purpose: Cash-out refinances carry higher adjustments than purchase loans or rate-and-term refinances.

A borrower with a 680 credit score and 5% down might face LLPAs totaling 1.75–2.25% of the loan amount — $5,250–$6,750 on a $300,000 loan — either paid at closing or absorbed as a higher rate. A borrower at 740+ with 20% down might face LLPAs of 0.25% or less. This is why the headline rate you see advertised rarely reflects what you'll actually be offered — your specific combination of credit score, LTV, and property type determines your actual pricing. See our mortgage points guide for how to use discount points to buy down the rate that LLPAs produce.

30-Year vs. 15-Year Conventional Loans

Conventional loans are available in both 30-year and 15-year terms, and the choice between them is one of the most consequential decisions in the mortgage process.

The 30-year fixed-rate mortgage is the dominant choice — lower monthly payments spread over a longer period, freeing up cash flow for other financial priorities. As of late August 2026, the average 30-year fixed rate is in the mid-6% range per Freddie Mac's Primary Mortgage Market Survey.

The 15-year fixed-rate mortgage carries a lower interest rate — typically 0.5–0.75 percentage points below the 30-year rate — and cuts your total interest cost dramatically. The trade-off is a significantly higher monthly payment.

Here's how the two terms compare on a $400,000 loan at current rates:

The 15-year loan saves over $300,000 in interest over the full term — but requires $823 more per month. The right choice depends on your cash flow, your other financial priorities (investing, debt payoff, retirement savings), and how long you plan to keep the loan. A full break-even analysis and side-by-side decision framework will be covered in our dedicated 15 vs. 30-year mortgage guide.

HomeReady and Home Possible Programs

Two special conventional programs are worth knowing if your down payment or income is a constraint:

Fannie Mae HomeReady

HomeReady allows 3% down payments for borrowers whose income is at or below 80% of the area median income (AMI) for the property's location. Co-borrower income from non-occupant household members (such as parents) can be considered in qualifying. Reduced mortgage insurance rates apply compared to standard conventional PMI, and a homebuyer education course is required. Use Fannie Mae's AMI Lookup Tool to check income eligibility in your area.

Freddie Mac Home Possible

Home Possible similarly allows 3% down for borrowers at or below 80% AMI. It's particularly flexible for multi-generational households and borrowers with multiple income sources. Like HomeReady, it requires a homebuyer education course and offers reduced PMI rates. Use Freddie Mac's eligibility tool to verify income limits for your target area.

Both programs are conventional loans that follow standard Fannie/Freddie guidelines — they're not government loan programs. That means the same PMI cancellation rules apply, and neither carries the lifetime MIP burden of FHA loans.

Both programs can also be combined with state and local down payment assistance grants, which can cover your 3% contribution entirely in many markets. See our no-money-down home buying guide for a full breakdown of DPA programs that layer with conventional financing.

Eligible Property Types

One of conventional lending's meaningful advantages over government-backed loans is its flexibility across property types:

• Primary residence: All conventional programs available. Lowest down payment minimums and best pricing.
• Second home / vacation property: Allowed with at least 10% down. Must be located a reasonable distance from your primary residence and available for your personal use throughout the year.
• Investment property: Allowed with 15–25% down depending on the number of units. Higher credit score and reserve requirements apply. FHA loans do not permit investment property purchases.
• 2–4 unit properties: Eligible as either a primary residence (owner must occupy one unit) or investment property. Multi-unit limits scale upward as shown in the loan limits table above.
• Condominiums: Eligible when the condo project meets Fannie/Freddie approval standards. Warrantable condos (those meeting all project guidelines) get standard pricing; non-warrantable condos face additional requirements or may not qualify.
• Manufactured homes: Eligible with additional requirements and typically higher pricing than site-built homes.

Conventional vs. FHA: Which Is Right for You?

The choice between a conventional and FHA loan comes down primarily to your credit score and how long you'll keep the loan. Here's the condensed version:

• Choose conventional if your credit score is 680 or above, you can put down 5% or more, and you want the ability to cancel mortgage insurance. Conventional is almost always cheaper over the long term for borrowers who qualify at competitive pricing tiers.
• Choose FHA if your credit score is below 680, you've had recent credit events like bankruptcy or foreclosure, your DTI is above 45%, or your down payment is coming entirely from gift funds with no personal contribution. FHA is more accessible but carries lifetime mortgage insurance for most borrowers.

The mortgage insurance math is the most important comparison point. A conventional borrower who reaches 20% equity eliminates PMI entirely. An FHA borrower with less than 10% down pays MIP for the life of the loan — often $40,000–$60,000 more in total insurance costs on a typical loan amount. See our complete FHA vs. conventional loan comparison for a side-by-side cost analysis at different credit score tiers.

How to Apply and Qualify for a Conventional Loan

The conventional loan process follows the same basic path as any mortgage:

1. Check your credit and calculate your DTI. Pull your credit reports from AnnualCreditReport.com and dispute any errors. Calculate your back-end DTI by dividing your total monthly debt payments by your gross monthly income. Both numbers determine your pricing tier before you talk to a single lender.
2. Determine your target loan amount and county limit. Confirm your target home price puts your loan amount below the $832,750 conforming limit for your county (or the applicable high-cost limit). If your loan amount will exceed the limit, you'll need to plan for either a larger down payment or jumbo financing.
3. Get preapproved — not just prequalified. A preapproval involves a hard credit pull and verification of income, assets, and employment. It's what sellers take seriously when evaluating offers. See our mortgage preapproval guide for the full document checklist and process.
4. Shop at least three lenders. Rates and fees on identical conventional loans can vary by 0.5–1.0 percentage points between lenders. A 2024 Freddie Mac study found borrowers who got at least two quotes saved an average of $1,500 over the life of their loan. Compare current rates at our mortgage rate comparison page.
5. Lock your rate. Once you have an accepted offer on a home, lock your interest rate with your chosen lender. Lock periods typically run 30–60 days. See our rate lock guide for how to choose the right lock period and what can change after you lock.
6. Complete underwriting and close. Your lender's underwriting team verifies all documentation and orders an appraisal. Once approved, you review the Closing Disclosure, confirm all numbers match your Loan Estimate, and sign at closing. Our closing costs guide explains every line item you'll see.
