Understanding the Two Most Popular Loan Programs
Conventional loans and FHA loans are the two most widely used mortgage programs in the United States. Together, they account for the vast majority of home purchase financing. While both can get you into a home, they differ significantly in terms of down payment requirements, credit score thresholds, mortgage insurance costs, and long-term financial implications. Choosing the right one depends on your specific financial profile and goals.
Down Payment Comparison
FHA loans require a minimum down payment of 3.5% with a credit score of 580 or higher. Conventional loans can go as low as 3% down through the Conventional 97 program, and 5% down is the most common conventional minimum. On a $350,000 home, the difference between 3% down ($10,500) and 3.5% down ($12,250) is only $1,750. The down payment difference alone is rarely the deciding factor between the two programs.
What matters more is how the down payment amount affects mortgage insurance costs and the total cost of the loan over time. This is where the two programs diverge significantly.
Mortgage Insurance: The Critical Difference
FHA loans require an upfront mortgage insurance premium (UFMIP) of 1.75% of the loan amount (typically financed into the loan) plus an annual mortgage insurance premium (MIP) of 0.55% that is paid monthly. For loans with less than 10% down, FHA MIP lasts for the entire life of the loan. The only way to eliminate it is to refinance into a conventional loan once you have sufficient equity and credit score.
Conventional loans with less than 20% down require private mortgage insurance (PMI), but the cost varies based on credit score and loan-to-value ratio. A borrower with a 760 credit score might pay 0.25% to 0.35% annually in PMI, while a borrower with a 660 score might pay 0.80% to 1.00%. The crucial advantage: conventional PMI automatically cancels when the loan balance reaches 78% of the original home value, and you can request cancellation at 80%. This makes conventional loans significantly cheaper over time for borrowers with good credit.
Credit Score Requirements
FHA loans are accessible to borrowers with credit scores as low as 500 (with 10% down) or 580 (with 3.5% down). This makes FHA the go-to program for borrowers with credit challenges. Conventional loans technically allow scores as low as 620, but the best pricing kicks in at 740 and above. Below 680, FHA is often the better deal because conventional PMI rates become prohibitively expensive for lower credit scores.

Debt-to-Income Flexibility
FHA loans allow higher debt-to-income ratios than conventional loans, sometimes up to 56.9% with strong compensating factors through the automated underwriting system. Conventional loans typically cap at 50% DTI, with most approvals in the 43% to 45% range. For borrowers with significant existing debt (student loans, car payments, credit cards), FHA's more generous DTI limits can make the difference between approval and denial.
Property Type Considerations
Both FHA and conventional loans allow single-family homes, 2-4 unit properties, condos, and townhomes. However, FHA has stricter property condition requirements. The FHA appraisal checks for health and safety issues that a conventional appraisal might overlook. For condominiums, FHA requires the condo project to be FHA-approved or qualify for single-unit approval, which limits options in some markets. Conventional loans have fewer condo restrictions.
Making the Right Choice
Here is a simplified decision framework: if your credit score is below 680 and you have limited savings for a down payment, FHA is likely your best option. If your credit score is 720 or above and you can put down 5% or more, conventional is almost always cheaper over time due to lower mortgage insurance costs and automatic PMI cancellation. If you fall somewhere in between, the answer depends on your specific numbers.
