USDA, FHA, and Conventional Loans: What Sets Them Apart
The three loan types differ in who backs them, what down payment you need, and where you can buy
USDA loans are backed by the U.S. Department of Agriculture and require no down payment. They are only for properties in rural areas, and you must meet income limits based on your county. FHA loans are insured by the Federal Housing Administration and require a 3.5% down payment minimum. They work in any area and have more flexible credit requirements than conventional loans. Conventional loans are not government-backed; a bank or lender funds them directly. They typically require a 5% to 20% down payment and stricter credit and income verification.
Each loan type has different costs, restrictions, and trade-offs. Understanding which one fits your situation — your location, savings, credit history, and income — helps you move forward without surprises later.
Key Takeaways
- USDA loans require zero down payment but only work in rural areas and have income caps that vary by county.
- FHA loans work anywhere and accept lower credit scores, but charge mortgage insurance for the life of the loan if you put down less than 10%.
- Conventional loans have no geographic or income restrictions, but usually demand a larger down payment and stronger credit history.
- All three charge interest rates that depend on your credit score, the current market, and the lender you choose.
USDA loans: zero down, rural properties only
A USDA loan covers 100% of the home's purchase price, so you do not need to save a down payment. The catch is location: the property must sit in a designated rural area. The USDA maintains a map showing which counties and towns may have access to; you can check your address on the USDA Rural Development website before you start house hunting. Properties in suburbs of major cities usually do not may have access to, even if they feel rural to you.
Income limits apply and vary by county. A county's limit depends on the median income in that area. If your household income exceeds the limit, you cannot use a USDA loan in that county, even if you meet every other requirement. You can look up your county's limit on the USDA website before you apply. The income cap is usually 115% of the area median income, though some counties have different thresholds.
USDA loans charge a may provide fee (a one-time cost, usually 2% of the loan amount) and an annual fee (typically 0.35% of the remaining loan balance each year). These costs are rolled into your monthly payment. Interest rates are competitive with FHA and conventional loans and depend on your credit score and the current market.
FHA loans: lower down payment, work anywhere
An FHA loan requires a minimum 3.5% down payment, which is lower than most conventional loans. There is no income cap and no geographic restriction — FHA loans work in any neighborhood, urban or rural. Credit score requirements are more forgiving than conventional loans; some lenders will work with scores in the 580 range, though a higher score gets you a better interest rate.
The trade-off is mortgage insurance. FHA loans charge an upfront mortgage insurance premium (usually 1.75% of the loan amount, added to what you borrow) and an annual premium (0.55% to 0.80% of the loan balance per year, depending on your down payment and loan term). If you put down less than 10%, you pay the annual premium for the entire life of the loan. If you put down 10% or more, the annual premium stops after 11 years. This insurance protects the lender if you stop paying, but it increases your monthly cost.
FHA loans also have a debt-to-income limit: your total monthly debt payments (including the new mortgage) cannot exceed 43% to 50% of your gross monthly income, depending on the lender. This is stricter than some conventional lenders allow.
Conventional loans: no government backing, higher down payment
A conventional loan is funded by a bank or private lender with no government may provide. Down payment requirements start at 5% for some borrowers but often run 10% to 20%. The higher your down payment, the better your interest rate and the lower your monthly cost. If you put down less than 20%, you pay private mortgage insurance (PMI), which protects the lender. PMI typically costs 0.5% to 1.5% of the loan amount per year and can be removed once you have paid down the loan to 80% of the home's value.
Credit score requirements are stricter than FHA: most conventional lenders want a score of 620 or higher, and a score of 740 or above gets you the best rates. Debt-to-income limits are usually 43% to 50%, similar to FHA, though some lenders are more flexible.
Interest rates on conventional loans are set by the lender and the market. Because there is no government may provide, rates can be higher or lower than FHA or USDA depending on your credit profile and the lender's risk assessment. Conventional loans also have fewer restrictions on property type and condition, which can matter if you are buying an older home or a property that needs work.
Comparing costs: down payment, insurance, and interest
| Loan Type | Down Payment | Insurance Cost | Geographic Limits | Income Limits |
|---|---|---|---|---|
| USDA | 0% | may provide fee (2%) + annual fee (0.35%) | Rural areas only | Yes, varies by county |
| FHA | 3.5% minimum | Upfront (1.75%) + annual (0.55%–0.80%) | None | No |
| Conventional | 5%–20% | PMI (0.5%–1.5% annually, if down payment < 20%) | None | No |
The total cost of each loan depends on your specific situation. A USDA loan saves you a down payment but only works in rural areas. An FHA loan works anywhere and accepts lower credit scores, but the mortgage insurance can add thousands to the cost over time. A conventional loan may have a lower interest rate if your credit is strong, but requires more cash upfront.
Which loan makes sense for your situation
Choose USDA if you are buying in a rural area, have limited savings, and your household income is below your county's limit. The zero down payment is a major advantage if you have not saved much. If your income exceeds the limit or the property is outside a rural zone, USDA is not an option.
Choose FHA if you are buying in any location, have 3.5% to 10% saved for a down payment, and your credit score is below 640. FHA is also useful if your debt-to-income ratio is tight; some FHA lenders are more flexible than conventional lenders on this measure. Be aware that if you put down less than 10%, you will pay mortgage insurance for 30 years (the life of a typical mortgage).
Choose conventional if you have saved 10% or more for a down payment, your credit score is 640 or higher, and you want to avoid long-term mortgage insurance. Conventional loans also make sense if you are buying a property that is older or needs repairs, because conventional lenders have fewer restrictions on condition. If your down payment is 20% or more, you avoid PMI entirely, which can save you thousands.
Interest rates and what affects them
All three loan types charge interest rates that move with the market. Your personal rate depends on your credit score, the loan term (15 or 30 years), the size of your down payment, and the lender you choose. A higher credit score and a larger down payment both lower your rate. Shopping with multiple lenders can reveal rate differences of 0.25% to 0.5%, which adds up over time.
USDA and FHA rates are often competitive with or slightly higher than conventional rates, depending on market conditions. Because USDA and FHA loans are government-backed, lenders take less risk, which can translate to lower rates for borrowers with weaker credit. Conventional rates reward borrowers with strong credit and large down payments.
Interest rates change daily. When you are ready to move forward, get quotes from at least three lenders for the loan type you are considering. Each quote should show the interest rate, the annual percentage rate (APR), and all fees so you can compare the true cost.
Frequently Asked Questions
Can I switch from one loan type to another after I start the process?
Yes, but it costs time and money. Switching means restarting the application with a new lender, paying new application and appraisal fees, and waiting for new underwriting. If you discover you do not may have access to for your first choice, ask your lender whether switching is worth the delay and cost, or start fresh with a different loan type immediately.
What credit score do I need for each loan type?
USDA loans typically require a score of 580 or higher, though some lenders go lower. FHA loans start at 580 and work up from there. Conventional loans usually require 620 or higher, with better rates at 740 and above. Your exact score requirement depends on the lender and the rest of your financial profile.
Can I use a USDA loan if I have used one before?
Yes, USDA loans can be used multiple times, but you can only have one USDA loan at a time. If you already own a home with a USDA loan, you must sell it or pay off the loan before you can get another one.
Do I have to pay mortgage insurance forever on an FHA loan?
Only if you put down less than 10%. If you put down 10% or more, the annual mortgage insurance premium stops after 11 years of payments. If you put down less than 10%, the insurance continues for the life of the loan, even after you have paid it down significantly.
What happens if I put down more than the minimum?
A larger down payment lowers your interest rate, reduces or eliminates mortgage insurance, and decreases your monthly payment. For conventional loans, putting down 20% or more eliminates PMI. For FHA loans, putting down 10% or more eliminates the annual insurance after 11 years. For USDA loans, you cannot put down more than the purchase price, but a larger down payment still improves your rate.
