Buying a home can be overwhelming, but understanding how Fannie Mae conventional loans work can lessen the headaches that come with homeownership. These loans remain one of the most popular financing options for home buyers, thanks to their flexible terms, competitive interest rates, and guidelines that support both new and repeat home buyers.
If you’re exploring your options and want to know the requirements for Fannie Mae conventional loans, this guide breaks it all down in plain language.
What is a conventional loan?
Conventional loans are loans backed by private lenders, not by the government, and are divided into two types: conforming and nonconforming loans.
Conforming loans meet the criteria established by Fannie Mae and Freddie Mac, while nonconforming loans are those that don’t meet at least one of the criteria.
Fannie Mae and Freddie Mac help make it easier for people to get home loans by buying loans from banks and other lenders. The Federal Housing Finance Agency (FHFA) oversees these entities to make sure they work responsibly, keep the housing market stable, and protect taxpayers from bearing the cost of potential losses.
What are the current Fannie Mae conventional loan requirements?
There are key areas that help lenders measure risk and determine whether a borrower can afford the monthly mortgage payment over the full loan term. While every applicant’s situation is different, the following criteria play the biggest role.
Down payment expectations
Your purchase price, property value, and overall loan amount determine how much needs to be paid upfront. Buyers purchasing a primary residence typically face lower requirements, while second homes or investment property purchases often call for higher percentages.
If you’re buying a home for the first time, as little as 3% down payment may be required. However, you may choose to pay more to lower your monthly mortgage payments and interest rates and to build home equity faster.
Fannie Mae also allows certain forms of payment assistance, such as gifts from family or down payment programs, which can help buyers who need support to get started.
Credit history and minimum credit score requirement
Conventional financing still places a strong emphasis on good credit, but it’s not Fannie Mae that sets a universal minimum credit score requirement. Instead, Fannie Mae evaluates your overall credit profile through its automated underwriting system, while lenders set their own internal guidelines based on that framework.
In practice, many lenders choose to work with a minimum score of around 620 or higher for conventional loans, but that’s a lender rule, not a hard requirement from Fannie Mae.
A strong credit history can lead to better pricing, lower fees, and more flexible options when you apply for loans or credit. It also shows that you can manage your monthly mortgage payment consistently. A previous bankruptcy or late payments doesn’t always mean you’re disqualified, but lenders will look closely at how much time has passed from your last instance of bankruptcy or late payment and whether your finances have improved since then.
Debt-to-income (DTI) ratio
Your DTI reveals how much of your monthly earnings is used to pay existing obligations. Fannie Mae typically allows a DTI up to 45%, though some borrowers may qualify at slightly higher ratios depending on automated underwriting results, compensating factors, and overall credit strength.
This calculation helps lenders determine whether you can afford your future monthly mortgage payment without stretching beyond your financial comfort zone.
Income, employment, and area median income
Stable income plays a major role in qualifying. Lenders review your job history, earnings, W-2s, tax returns, and other documentation to confirm your current financial stability.
Some Fannie Mae programs, especially those designed for expanding access to credit, include guidelines tied to area median income. These guidelines help support households in certain communities or high-cost areas where property values and loan sizes are higher.
Appraisal, property type, and property standards
An appraisal serves two main purposes: it ensures the home is worth the price you’ve agreed to pay and confirms that it meets basic safety and livability standards. The specific appraisal requirements can vary based on your plans for the property; that is, whether you’re going to use it as your main home, a vacation house, or a rental. Fannie Mae also has specific guidelines for condos, multi-unit homes, and manufactured housing.
Interest rate choices: Fixed-rate mortgage or adjustable-rate mortgage loans
Conventional financing offers two interest rate options. Fixed-rate mortgages (FRM) maintain the same interest rate throughout the loan term, whereas adjustable-rate mortgages (ARM) have interest rates that can fluctuate depending on market conditions.
Many borrowers prefer fixed rates for stability, but ARM loans — which tend to have lower initial rates — can be appealing if you plan to refinance or move before the adjustment period.
Loan term, closing costs, and payment requirements
The duration of your loan plays a big role in how much you’ll pay. A shorter loan term means you’ll have larger monthly payments but will pay less in total interest. Conversely, a longer loan term will lower your monthly payments by spreading them out, but you’ll end up paying more interest down the road.
Along with your regular payments, it’s important to factor in closing costs as part of your expenses. These are one-time expenses that usually amount to 2–5% of the loan’s total value. Closing costs pay for various services needed to finalize your loan, such as appraisals, underwriting, and other fees charged by the lender.
Finally, when underwriters review your application, they consider your total monthly housing expense, which includes the loan’s principal and interest, as well as taxes, homeowners’ insurance, and sometimes mortgage insurance (if your down payment is less than 20%).
Loan limits, high-cost areas, and jumbo loan considerations
Each year, the FHFA sets new loan limits for conforming loans. The limits vary across the continental United States, Alaska, Hawaii, and the Virgin Islands, with homes in high-cost areas often having higher allowable limits due to elevated housing prices.
If your loan exceeds the limit for your region, it becomes a jumbo loan, which imposes stricter rules and often requires stronger credit, larger down payments, and additional reserves.
Loan approval and costs: Conventional loans vs. government loans
Government-backed loans, such as those offered by the Federal Housing Administration, the Department of Veterans Affairs, or the Department of Housing, are often easier to qualify for due to their more lenient credit requirements. However, they can end up costing more over time because they usually require you to pay mortgage insurance premiums (MIP) the whole time you have the loan (unless you refinance).
In contrast, conventional loans like Fannie Mae loans may only require MIPs for a limited time, which could save you money in the long run.
Another distinction is that conventional loans are often grouped together and sold as investments called mortgage-backed securities. Doing this helps ensure there’s enough money available in the market for future homebuyers, keeping loan costs reasonable.
Why conventional loans remain a strong option for home buyers
Fannie Mae’s guidelines are built to support affordability while maintaining stability across the housing and mortgage markets. With benefits such as competitive interest rates, multiple term options, and flexible down payment programs, conventional loans remain one of the most balanced paths toward homeownership for a wide range of borrowers.
Buyers with good credit, steady income, and clear long-term goals often find that conventional financing aligns well with both their budget and plans.
