Conventional loans explained for today's homebuyers
October 29, 2026
Ask a dozen buyers how they plan to finance a home and a good number will say a conventional loan, even if they couldn't explain why. These mortgages are not insured or guaranteed by a federal agency, which sets them apart from FHA, VA, and USDA options. That simple difference shapes everything from credit standards to how flexible the terms can be. Here is what they are, who tends to fit them, and how to decide whether one belongs in your plans.
Most conventional loans follow guidelines set by Fannie Mae and Freddie Mac, the two government-sponsored enterprises that buy mortgages from lenders. Loans that meet those guidelines are called conforming, and that standard is what keeps pricing competitive for many borrowers. Loans above the conforming size limit are called jumbo loans and usually come with stricter underwriting. Those size limits change each year, so the cap that applied to a neighbor's purchase may not apply to yours. Because the guidelines come from the investors who buy the loans, lenders have less room to invent their own rules.
Credit score is one of the biggest levers on a conventional file. Lenders look at it alongside your debt-to-income ratio, which compares monthly debt payments to gross income. Down payment requirements are more flexible than many people expect, and several programs allow relatively modest cash to close. Smaller down payments usually mean private mortgage insurance, which protects the lender and can be removed once enough equity builds. Stronger credit and a larger down payment both tend to lower the monthly cost, and improvements in one area often help the others.
