Buying a home is one of the most significant financial decisions you will ever make. Before you can start house hunting in earnest, you need to figure out how you are going to pay for it. For most people, that means taking out a mortgage. And when it comes to mortgages, two options dominate the conversation: FHA loans and conventional loans.
Both loan types can help you achieve homeownership, but they work differently, come with different requirements, and suit different types of borrowers. Choosing the wrong one can cost you thousands of dollars over the life of your loan, so understanding the distinctions is critical.
In this comprehensive guide, we will break down everything you need to know about FHA loans versus conventional loans — including eligibility requirements, costs, down payment rules, mortgage insurance, and which type of loan is best for your specific financial situation.
What Is an FHA Loan?
An FHA loan is a mortgage backed by the Federal Housing Administration, a government agency within the U.S. Department of Housing and Urban Development (HUD). Because the government insures these loans, lenders face less risk if a borrower defaults. This protection allows lenders to offer FHA loans to borrowers who might not qualify for conventional financing.
FHA loans were created in 1934 during the Great Depression to stimulate the housing market and help more Americans achieve homeownership. Today, they remain one of the most popular loan options for first-time homebuyers and people with limited savings or less-than-perfect credit.
Key characteristics of FHA loans include:
- Government-backed insurance through the Federal Housing Administration
- Lower minimum credit score requirements (as low as 500 with 10% down, or 580 with 3.5% down)
- Minimum down payment of 3.5% for qualifying borrowers
- Mandatory mortgage insurance premiums (MIP) for the life of the loan in most cases
- Loan limits set by the FHA based on geographic area
- Must be used for a primary residence
What Is a Conventional Loan?
A conventional loan is any mortgage that is not backed or insured by a federal government agency. Instead, these loans follow guidelines set by Fannie Mae and Freddie Mac, the two government-sponsored enterprises that purchase most mortgages from lenders in the secondary market.
Because conventional loans are not government-insured, lenders take on more risk. This means they typically require stronger financial qualifications from borrowers, including higher credit scores, lower debt-to-income ratios, and in many cases, larger down payments.
Key characteristics of conventional loans include:
- Not backed by any government agency
- Conforming loans must fall within Fannie Mae and Freddie Mac loan limits
- Minimum credit score typically 620 or higher
- Down payments as low as 3% for certain programs
- Private mortgage insurance (PMI) required if down payment is less than 20%
- PMI can be cancelled once you reach 20% equity
- Can be used for primary residences, second homes, and investment properties
FHA Loan vs Conventional Loan: Side-by-Side Comparison
Before diving deeper into each category, here is a quick comparison of the core features of both loan types:
| Feature | FHA Loan | Conventional Loan |
| Minimum Credit Score | 500 (10% down) / 580 (3.5% down) | 620 (typical minimum) |
| Minimum Down Payment | 3.5% | 3% (some programs) |
| Mortgage Insurance | Required (MIP — often for life of loan) | PMI required if < 20% down; cancellable |
| Loan Limits (2024) | Up to $498,257 (standard areas) | Up to $766,550 (conforming) |
| Property Requirements | Strict appraisal and condition standards | Less restrictive |
| Property Types | Primary residence only | Primary, second home, investment |
| Debt-to-Income Ratio | Up to 57% (with compensating factors) | Up to 45–50% |
| Upfront Costs | 1.75% upfront MIP | No upfront mortgage insurance |
| Best For | Low credit, limited savings | Stronger credit, lower long-term cost |
Credit Score Requirements
FHA Loan Credit Score Requirements
One of the biggest advantages of FHA loans is their lenient credit score requirements. The FHA allows borrowers with credit scores as low as 500 to qualify, provided they can put down at least 10%. Borrowers with a score of 580 or higher only need a 3.5% down payment.
This makes FHA loans an attractive option for people who have had financial setbacks in the past — such as medical debt, job loss, or a bankruptcy that has since been resolved. It is important to note, however, that while the FHA sets minimum standards, individual lenders may impose stricter requirements known as lender overlays.
Conventional Loan Credit Score Requirements
Conventional loans are generally less forgiving when it comes to credit scores. Most lenders require a minimum score of 620 to qualify for a conventional mortgage. However, to get the best interest rates, you will typically need a score of 740 or higher.
The relationship between credit score and interest rate is much more pronounced with conventional loans. Even a small difference in credit score can mean a significantly different interest rate, which can add up to tens of thousands of dollars over a 30-year loan term.
Down Payment Requirements
FHA Loan Down Payments
FHA loans allow a minimum down payment of just 3.5% for borrowers with a credit score of 580 or above. On a $300,000 home, that is a down payment of only $10,500. This low threshold makes homeownership accessible to many people who have not had years to save.
The funds for an FHA down payment can also come from a gift from a family member or an approved down payment assistance program, giving borrowers even more flexibility in how they source their funds.
Conventional Loan Down Payments
Conventional loans technically allow down payments as low as 3% through programs like Fannie Mae’s HomeReady and Freddie Mac’s Home Possible. However, putting down less than 20% triggers private mortgage insurance (PMI), which adds to your monthly costs.
For borrowers who can afford a 20% down payment, conventional loans become significantly more attractive because PMI is eliminated entirely, reducing the monthly payment and total loan cost substantially over the life of the mortgage.
Mortgage Insurance: A Critical Difference
Mortgage insurance is one of the most significant cost differences between FHA and conventional loans, and it deserves careful attention before you decide which loan to pursue.
FHA Mortgage Insurance Premium (MIP)
FHA loans require two types of mortgage insurance:
- Upfront MIP: 1.75% of the loan amount, paid at closing or rolled into the loan balance
- Annual MIP: ranges from 0.15% to 0.75% of the loan amount per year, depending on loan size, term, and down payment amount
For a $300,000 FHA loan, the upfront MIP would be $5,250. If your annual MIP rate is 0.55%, you would pay approximately $137.50 per month in mortgage insurance on top of your principal and interest payment.
Here is the critical catch: for most FHA loans made after June 2013 with down payments less than 10%, MIP cannot be cancelled. You pay it for the entire life of the loan. The only way to eliminate it is to refinance into a conventional loan once you have enough equity built up.
Conventional PMI
Private mortgage insurance on conventional loans typically costs between 0.2% and 2% of the loan amount per year, depending on your credit score and loan-to-value ratio.
The major advantage over FHA MIP is that conventional PMI is cancellable. Under the Homeowners Protection Act, lenders must automatically cancel PMI once your loan balance reaches 78% of the original purchase price. You can also formally request cancellation when your balance drops to 80%.
If your home appreciates in value, you may be able to request PMI removal even sooner based on the new appraised value — though this is subject to lender approval and typically requires being at least two years into your loan.
Loan Limits
Both FHA and conventional loans have maximum loan amounts, though they are determined by different bodies and updated on different schedules.
FHA Loan Limits
FHA loan limits vary by county and are updated annually. For 2024, the standard FHA loan limit for a single-family home is $498,257 in most parts of the country. In high-cost areas like San Francisco, New York City, and Honolulu, limits can be as high as $1,149,825.
If the home you want to buy exceeds the FHA loan limit for your area, you will need to look at conventional or jumbo financing options instead.
Conventional Loan Limits
Conforming conventional loans must stay within limits set by the Federal Housing Finance Agency (FHFA). For 2024, the baseline conforming loan limit is $766,550 for a single-family home in most areas, with higher limits in designated high-cost markets.
Loans above these limits are known as jumbo loans and come with stricter underwriting requirements, though they are still classified as conventional mortgages.
Property Requirements
FHA Property Standards
One often-overlooked aspect of FHA loans is that the property itself must meet specific habitability standards. FHA appraisers evaluate not just the market value of the home, but also its condition and safety. The home must be safe, sound, and structurally secure.
This means issues like peeling paint in homes built before 1978, roof damage, plumbing problems, or structural defects can cause an FHA loan to be denied. Sellers of older or fixer-upper properties may be reluctant to accept FHA offers because of these more rigorous inspection requirements.
Conventional Property Standards
Conventional loans are less restrictive about property condition. While the home still needs to appraise at or above the purchase price, the appraisal is primarily focused on market value rather than habitability. This gives buyers more flexibility when purchasing older homes or properties that need cosmetic or minor repairs.
Debt-to-Income Ratio
Your debt-to-income (DTI) ratio is the percentage of your gross monthly income that goes toward all debt payments combined. Both loan types consider this metric carefully, but they treat it differently.
FHA loans are generally more flexible with DTI ratios. Many FHA lenders will approve borrowers with DTI ratios up to 50% or even higher when the borrower has compensating factors — such as significant cash reserves, a long history of on-time payments, or a strong employment record.
Conventional loans typically cap DTI ratios at 45%, though automated underwriting systems may approve borrowers up to 50% if they have strong compensating factors like high credit scores and larger down payments. Exceeding these thresholds usually results in a denial without a manual underwriting review.
Interest Rates: FHA vs Conventional
Contrary to what many borrowers assume, FHA loans do not always carry lower interest rates than conventional loans. The relationship is more nuanced and depends heavily on the borrower’s credit profile.
Because FHA loans are government-backed, lenders face less default risk and can sometimes offer competitive base rates. However, when you factor in the mandatory mortgage insurance premiums, the total monthly cost of an FHA loan is often higher than a conventional loan for well-qualified borrowers.
For borrowers with credit scores in the 580 to 620 range, FHA loans frequently offer a better total cost picture than conventional alternatives — because conventional lenders charge significantly higher rates for low-credit borrowers, and PMI costs are also elevated at that credit tier.
For borrowers with credit scores above 720 who can make a 20% down payment, conventional loans are almost always the cheaper option over the long run, particularly once the absence of mortgage insurance is factored in.
Who Should Choose an FHA Loan?
FHA loans make the most sense in the following situations:
- Your credit score is below 620 and you cannot qualify for a conventional loan
- You have limited savings and need to make a smaller down payment
- You have had a past bankruptcy or foreclosure but have since rebuilt your credit
- You have a higher debt-to-income ratio that conventional lenders will not approve
- You are a first-time homebuyer looking for accessible and flexible financing
- You are buying a home in a moderate price range that falls within FHA loan limits
FHA loans are not exclusively for first-time buyers, but they are especially beneficial for people who are just getting started and have not yet had the opportunity to build substantial savings or an extended credit history.
Who Should Choose a Conventional Loan?
Conventional loans are typically the better choice when:
- Your credit score is 620 or higher — and especially when it is 720 or above
- You can afford a 20% down payment, eliminating mortgage insurance entirely
- You want to buy a second home or an investment property
- The property you are purchasing does not meet FHA condition requirements
- You are buying in a high-cost area and need a larger loan amount
- You want the option to cancel mortgage insurance once you reach 20% equity
- You want to minimize your total cost of borrowing over the life of the loan
For financially strong borrowers, conventional loans typically offer a lower total cost of homeownership over time — particularly because of the ability to eliminate PMI once equity reaches 20%.
The True Cost Over Time: A Realistic Example
To make this concrete, consider a $300,000 home purchase with a 30-year fixed mortgage. Compare two borrowers: one using an FHA loan with 3.5% down, and one using a conventional loan with 5% down.
| FHA Loan (3.5% down) | Conventional Loan (5% down) | |
| Purchase Price | $300,000 | $300,000 |
| Down Payment | $10,500 (3.5%) | $15,000 (5%) |
| Loan Amount | $289,500 | $285,000 |
| Upfront MIP / Cost | $5,066 (rolled into loan) | None |
| Monthly MIP / PMI (est.) | ~$133/month | ~$95/month |
| Years of Mortgage Insurance | 30 years (full loan term) | ~7–9 years (until 20% equity) |
| Total MIP / PMI Paid (est.) | ~$47,880 | ~$7,980 |
As this example illustrates, the long-term cost of FHA mortgage insurance can be substantial. A borrower who qualifies for a conventional loan and can eventually eliminate PMI may save close to $40,000 over 30 years — even if the conventional monthly payment starts out slightly higher.
However, for borrowers who could not otherwise qualify for a conventional loan or save a larger down payment, the FHA route still delivers tremendous value. Getting into a home years earlier, building equity, and avoiding rising rents can more than offset the higher mortgage insurance costs over time.
Can You Switch From an FHA Loan to a Conventional Loan?
Yes, and this is actually a common and smart strategy for FHA borrowers. Since FHA MIP generally cannot be cancelled on loans with less than 10% down, refinancing into a conventional loan is the most direct path to eliminating mortgage insurance once you have built sufficient equity.
To refinance successfully, you will generally need at least 20% equity in the home, a credit score of 620 or higher (though better rates require 700+), and full income and employment documentation to qualify for the new loan.
The costs of refinancing — typically 2% to 5% of the loan amount in closing costs — must be weighed against the monthly savings from eliminating MIP. A break-even analysis will help you determine how long it takes for the savings to outweigh the costs of refinancing.
Final Verdict: Which Loan Is Better?
There is no universal answer to whether FHA or conventional loans are better. The right choice depends entirely on your financial profile, your goals, and the specific property you want to purchase.
Choose an FHA loan if you have a lower credit score, limited down payment savings, or a higher debt-to-income ratio. It provides an accessible, viable path to homeownership that might otherwise be out of reach.
Choose a conventional loan if you have strong credit, can make a larger down payment, and want to minimize long-term costs. The ability to eliminate PMI and access a broader range of property types gives conventional financing a meaningful advantage for qualified borrowers.
The smartest move is to get pre-qualified for both loan types and compare the actual numbers — monthly payment, total interest, and total mortgage insurance cost — side by side with the help of a trusted mortgage professional. Ultimately, the best loan is the one that gets you into the right home at a cost you can sustainably manage for years to come.
