A conventional loan is the most common type of mortgage in the United States, accounting for roughly two-thirds of all home loans originated each year. Unlike FHA, VA, or USDA loans, a conventional mortgage is not insured or guaranteed by a federal agency — which gives lenders more flexibility but also means stricter qualification standards for borrowers.
Whether you are buying your first home or refinancing an existing mortgage, understanding how conventional loans work will help you decide if this option fits your financial situation. Use our mortgage payment calculator to estimate your monthly costs, and check your debt-to-income ratio before you apply.
Conventional Loan Definition
A conventional loan is any mortgage that is not backed by a government agency such as the Federal Housing Administration (FHA), the Department of Veterans Affairs (VA), or the U.S. Department of Agriculture (USDA). Instead, conventional loans are originated and funded by private lenders — banks, credit unions, and mortgage companies — and are typically sold to Fannie Mae or Freddie Mac on the secondary market.
Because there is no government guarantee protecting the lender against default, conventional loans generally require stronger credit profiles, larger down payments, and lower debt-to-income ratios than government-backed alternatives.
Conforming vs. Non-Conforming Loans
Conventional loans fall into two subcategories based on whether they meet the guidelines set by Fannie Mae and Freddie Mac:
- Conforming loans — these follow the loan limits and underwriting standards established by Fannie Mae and Freddie Mac. In 2026, the baseline conforming loan limit is $806,500 for a single-family home in most U.S. counties. High-cost areas such as parts of California, New York, and Hawaii have limits up to $1,209,750.
- Non-conforming loans (jumbo loans) — these exceed the conforming loan limits or do not meet other Fannie/Freddie guidelines. Jumbo loans typically require higher credit scores (700+), larger down payments (10%–20%), and carry slightly higher interest rates.
Most borrowers seeking a conventional mortgage will apply for a conforming loan because of the favorable rates and standardized process.
Minimum Requirements for a Conventional Loan
While each lender sets its own underwriting criteria, the following benchmarks apply to most conventional conforming loans:
Credit Score
The minimum credit score for a conventional loan is typically 620. However, borrowers with scores of 740 or above qualify for the best interest rates. Scores between 620 and 679 may result in higher rates and additional conditions such as a larger down payment or reserves.
Down Payment
Conventional loans offer down payments as low as 3% for first-time homebuyers through programs like Fannie Mae’s HomeReady and Freddie Mac’s Home Possible. Repeat buyers generally need at least 5% down. Putting 20% down eliminates the need for private mortgage insurance entirely.
Use our mortgage calculator to see how different down payment amounts affect your monthly payment.
Debt-to-Income Ratio (DTI)
Most lenders require a DTI ratio of 45% or below, though some will approve borrowers up to 50% with strong compensating factors like high credit scores or significant cash reserves. Your DTI is calculated by dividing your total monthly debt payments by your gross monthly income.
Employment and Income Verification
Lenders verify income through W-2s, tax returns, pay stubs, and bank statements. Self-employed borrowers typically need two years of tax returns showing stable or increasing income. For a full overview of what you will need, see our guide on documents needed for mortgage preapproval.
Reserves
Some lenders require two to six months of mortgage payments held in reserve, especially for investment properties, second homes, or borrowers with lower credit scores.
Private Mortgage Insurance (PMI)
If your down payment is less than 20%, your lender will require private mortgage insurance (PMI). PMI protects the lender — not you — in case you default on the loan. Here is what you need to know about PMI on a conventional loan:
- Cost: PMI typically ranges from 0.3% to 1.5% of the original loan amount per year, depending on your credit score and down payment. On a $300,000 loan, that translates to roughly $75 to $375 per month.
- Automatic cancellation: Under the Homeowners Protection Act, your lender must automatically cancel PMI when your loan balance reaches 78% of the original purchase price. You can also request cancellation once you reach 80% loan-to-value.
- Payment options: PMI can be paid monthly, as a single upfront premium at closing, or as a lender-paid option built into a slightly higher interest rate.
The ability to cancel PMI is a significant advantage conventional loans hold over FHA loans, where mortgage insurance premiums (MIP) remain for the life of the loan on most FHA mortgages originated today.
Conventional Loan Interest Rates
Conventional loans are available with both fixed and adjustable interest rates:
- Fixed-rate conventional loans — the most popular option. Your rate and monthly payment stay the same for the entire loan term (15 or 30 years). This provides predictability and protection against rising rates.
- Adjustable-rate conventional loans (ARMs) — the rate is fixed for an initial period (typically 5, 7, or 10 years) and then adjusts annually based on a market index. ARMs usually start with a lower rate than fixed loans, making them attractive to borrowers who plan to sell or refinance before the adjustment period begins. Read more in our guide to adjustable-rate mortgages.
Your actual rate depends on your credit score, down payment, loan amount, loan term, and current market conditions. Even a small difference in rate can save or cost tens of thousands of dollars over the life of the loan — use our amortization calculator to see the long-term impact.
Conventional Loan vs. FHA Loan
The FHA loan is the most common alternative to a conventional mortgage, especially for first-time buyers. Here is how they compare:
- Credit score: Conventional requires 620 minimum; FHA allows scores as low as 580 (or 500 with 10% down).
- Down payment: Conventional offers 3%–5% minimum; FHA requires 3.5% with a 580+ score.
- Mortgage insurance: Conventional PMI can be canceled at 80% LTV; FHA MIP lasts the life of the loan on most current FHA loans.
- Loan limits: Conventional conforming limits are $806,500 (baseline); FHA limits are $524,225 (baseline) in 2026.
- Property standards: FHA requires more stringent property condition standards; conventional is more flexible.
- Interest rates: FHA rates are often slightly lower, but the ongoing MIP can make FHA more expensive over time.
If you have a credit score above 700 and can put at least 5%–10% down, a conventional loan is often the better financial choice because you can avoid or quickly eliminate mortgage insurance.
Pros and Cons of Conventional Loans
Advantages
- PMI can be canceled once you reach 20% equity, reducing your long-term costs.
- Higher loan limits than FHA allow you to finance more expensive properties.
- Flexible terms — choose from 10, 15, 20, 25, or 30-year fixed, or various ARM options.
- Available for primary residences, second homes, and investment properties.
- Less restrictive property condition requirements than FHA.
- No upfront funding fee (unlike VA loans) or upfront mortgage insurance premium (unlike FHA).
Disadvantages
- Higher credit score requirement (620 minimum) compared to FHA (580).
- PMI costs can be substantial if your down payment is below 10%.
- Stricter DTI requirements than some government-backed loans.
- Rates may be higher for borrowers with credit scores below 700.
- No built-in assistance programs the way FHA and USDA loans support lower-income borrowers.
How to Apply for a Conventional Loan
The process follows the same general steps as any mortgage application:
- Check your credit and finances. Review your credit report, calculate your DTI, and determine how much you can afford.
- Get preapproved. Submit a preapproval application with at least two or three lenders to compare rates and terms. Preapproval letters are valid for 60 to 90 days — see how long mortgage preapproval lasts.
- Shop for a home. Make offers with confidence knowing your budget and preapproval status.
- Complete underwriting. The lender verifies your income, assets, and the property appraisal. Learn more about how long underwriting takes.
- Close on your home. Sign the final documents, pay closing costs, and receive the keys.

Frequently Asked Questions
What credit score do I need for a conventional loan?
The minimum credit score for most conventional loans is 620. However, a score of 740 or higher qualifies you for the best available interest rates. Borrowers with scores between 620 and 679 can still get approved but should expect higher rates and may need a larger down payment or additional reserves to compensate for the added risk.
How much down payment do I need for a conventional loan?
First-time homebuyers can put as little as 3% down through programs like Fannie Mae HomeReady or Freddie Mac Home Possible. Repeat buyers generally need at least 5%. Putting 20% down eliminates private mortgage insurance, which can save you hundreds of dollars per month. For investment properties, expect to put 15%–25% down.
Is a conventional loan better than an FHA loan?
It depends on your financial profile. If you have a credit score above 700 and at least 5%–10% for a down payment, a conventional loan is typically cheaper over time because you can cancel PMI once you reach 20% equity. FHA loans are often better for borrowers with lower credit scores (580–619) or limited savings, but the lifetime mortgage insurance premiums make FHA more expensive in the long run for well-qualified buyers.
When can I remove PMI from a conventional loan?
You can request PMI removal once your loan balance reaches 80% of the original purchase price and you have a good payment history. Your lender is required by law to automatically cancel PMI when the balance drops to 78% of the original value. If your home has appreciated significantly, you may also be able to get PMI removed earlier by ordering a new appraisal to demonstrate that your current loan-to-value ratio is below 80%.
What are the conventional loan limits for 2026?
The baseline conforming loan limit for 2026 is $806,500 for a single-family home in most counties across the United States. In designated high-cost areas, the ceiling reaches $1,209,750. For multi-unit properties, limits are higher — up to $1,548,975 for a four-unit property in high-cost areas. If you need to borrow above these limits, you will need a jumbo loan, which has stricter qualification requirements.
