Conventional loan requirements are the standards a lender uses to decide whether you qualify for a mortgage that is not backed by the federal government. Because the lender and the investors behind the loan carry the risk, the rules focus on your credit, your income, your debts and your down payment. If you are comparing loan types, this guide explains every requirement in plain English so you know where you stand before you apply.
What Is a Conventional Loan?
A conventional loan is a mortgage that is not insured by the FHA, VA or USDA. Most conventional loans are “conforming,” which means they follow the rules set by Fannie Mae and Freddie Mac, the two companies that buy mortgages from lenders. You can read the official rules in the Fannie Mae Selling Guide.
Conventional loans are the most common type of mortgage in the United States. They work for primary homes, second homes and investment properties, and they usually come with 15-year or 30-year fixed terms. If you are still deciding between loan types, our guide on FHA Loan Requirements shows how the government-backed option compares.
Conventional Loan Requirements at a Glance
Here are the main conventional loan requirements most lenders apply:
- Credit score: 620 or higher
- Down payment: as low as 3%, though 5% to 20% is common
- Debt-to-income ratio: usually 45% or lower, up to 50% in some cases
- Stable income: typically two years of work history
- Cash reserves: often 2 to 6 months of payments for some borrowers
- Property standards: the home must appraise at or above the price
- Loan size: within the conforming loan limit for your county
Let us look at each one.
1. Credit Score Requirements
The minimum credit score for a conventional loan is 620. Some lenders set their own higher floor, such as 640 or 660. Your score also affects your interest rate and your mortgage insurance cost. A borrower with a 760 score can pay noticeably less than one with a 640 score on the same loan.
If your score is below 620, you may still have options, including government-backed loans with softer credit rules. You can also work on your score first. The Consumer Financial Protection Bureau offers free guidance on credit and mortgages.
2. Down Payment Requirements
One of the most misunderstood conventional loan requirements is the down payment. You do not need 20% down. Many programs allow 3% down for first-time buyers, and 5% is common for other buyers. Putting down 20% or more helps you avoid private mortgage insurance (PMI) and usually lowers your monthly payment.
If you put down less than 20%, expect PMI. It is an extra monthly cost that protects the lender, and it can usually be removed later. When your balance reaches 80% of the home’s original value, you can ask your lender to cancel it. It ends automatically at 78%.
3. Debt-to-Income Ratio (DTI)
Your debt-to-income ratio compares your monthly debt payments to your gross monthly income. Under typical conventional loan requirements, lenders prefer a DTI of 45% or lower. Some borrowers with strong credit and savings can be approved with a DTI of up to 50%.
For example, if you earn $6,000 a month and your total debts, including your new mortgage payment, are $2,500, your DTI is about 42%. To lower it, pay down credit cards or car loans before you apply, and avoid opening new accounts.
4. Income and Employment History
Lenders want proof that your income is stable. Most ask for two years of employment history, plus recent pay stubs, W-2 forms and tax returns. If you are self-employed, expect to provide two years of tax returns and a profit and loss statement.
A gap in work history does not automatically disqualify you, but you will need to explain it. Lenders mainly look for income that is likely to continue.
5. Cash Reserves and Assets
Some borrowers must show reserves, which are savings left over after the down payment and closing costs. Two to six months of mortgage payments is a common range. Investment properties and larger loans often require more.
Lenders also check where your down payment comes from. Gift funds are allowed in many cases, but they need a signed gift letter and a paper trail.
6. Property and Appraisal Requirements
The home is the collateral, so it has to meet certain standards. The lender orders an appraisal to confirm the home is worth at least the purchase price. If the appraisal comes in low, you may need to renegotiate the price or bring more cash to closing.
Conventional loan requirements for the property are usually less strict than for FHA or VA loans, but the home must still be safe, livable and in sound condition. A home inspection before you buy is a smart step either way.
7. Conforming Loan Limits
Conventional loans that follow Fannie Mae and Freddie Mac rules must stay under a yearly limit set by the Federal Housing Finance Agency. The limit is higher in expensive areas. You can check the current numbers for your county on the FHFA website.
If you need to borrow more than the limit, you will need a jumbo loan, which has tougher qualifying rules.
Conventional Loan vs. Other Loan Types
Conventional loans often win for borrowers with good credit and some savings, because PMI can be cancelled and rates can be competitive. Government-backed loans can be easier to get with lower credit or smaller savings.

How to Prepare Before You Apply
A little preparation makes it easier to meet conventional loan requirements:
- Check your credit reports and fix any errors
- Pay down credit card balances to lower your DTI
- Save for your down payment and closing costs
- Gather pay stubs, W-2s, tax returns and bank statements
- Avoid big purchases or new credit before closing
Once you are approved, the next step is the closing. Our guide to the mortgage closing process walks you through what to expect, and the mortgage amortization schedule calculator shows how your payments are split between interest and principal.
A Personal Note from José María
When I research mortgage guides for this site, the thing I notice most is how often buyers assume they need 20% down or perfect credit. The official rules show that conventional loan requirements are more flexible than many people think. My advice is simple: compare the numbers carefully, ask lenders for a written estimate, and do not rush the decision.
