Choosing between a conventional and FHA loan in Louisiana comes down to your credit score, your down payment, and how long you plan to keep the mortgage. FHA loans give buyers with lower credit scores and smaller savings a path to homeownership, while conventional loans reward stronger credit profiles with lower long-term costs. Neither program is universally "better" — the right choice depends on your specific financial picture and the property you are buying.
This guide breaks down every major difference between the two loan types, explains when each one wins, and addresses the Louisiana-specific factors that shift the math in ways that national guides miss entirely.
What Are the Key Differences Between Conventional and FHA Loans?
The fastest way to understand these two programs is a direct comparison. The table below covers the five factors that matter most to Louisiana buyers making this decision.
| Factor | Conventional | FHA |
|---|---|---|
| Minimum Credit Score | 620 (most lenders) | 580 for 3.5% down; 500 with 10% down |
| Down Payment | 3% minimum (5% is more common) | 3.5% minimum |
| Mortgage Insurance | PMI — cancels at 20% equity | MIP — stays for life of loan (under 10% down) |
| Appraisal Standards | Market value focus | HUD minimum property standards required |
| 2026 Loan Limit (most LA parishes) | $806,500 (conforming) | $524,225 |
According to the Home Mortgage Disclosure Act data, approximately 38% of Louisiana purchase loans originated in 2024 were FHA loans, well above the national average of around 27%. That tells you how important this program is in our state — but it does not mean FHA is automatically the right fit for every buyer.
How Does Your Credit Score Change the Decision?
Your credit score is the single most important variable in the conventional-vs-FHA calculation. It determines not just whether you qualify, but how much each loan will actually cost you over time. The reason is straightforward: conventional loan pricing is heavily credit-score-driven, while FHA pricing is relatively flat across the score range.
With FHA, a borrower at 580 and a borrower at 740 pay nearly the same mortgage insurance rate — 0.55% annually on a standard 30-year loan with less than 5% equity. Conventional PMI, on the other hand, can range from as low as 0.25% for a 760+ score with 20% down all the way to 1.5% or more for a 620 score with 3% down.
Here is where the crossover happens in practice. Buyers with credit scores below 660 almost always pay less with FHA. Between 660 and 700, the two programs are competitive — and the winner depends on your down payment amount and the specific PMI quote. Above 700, conventional is nearly always the cheaper option because your PMI rate drops significantly and you can eventually eliminate it altogether.
In the Lake Charles market, I see a lot of buyers in the 640-680 range. For these borrowers, running the numbers on both programs side by side is critical. A $10 difference in monthly payment might not sound like much, but over 30 years that adds up to $3,600 — and the ability to drop PMI could save tens of thousands more.
How Do Down Payment Requirements Compare?
Both programs allow relatively low down payments, but the details differ in ways that matter. FHA loans require a minimum 3.5% down payment with a 580+ credit score. Conventional loans technically allow as little as 3% down through programs like Fannie Mae's HomeReady or Freddie Mac's Home Possible, though the standard minimum at most lenders is 5%.
On a $225,000 home — close to the median purchase price in many Louisiana parishes — the difference between 3% down ($6,750) and 3.5% down ($7,875) is $1,125. That is not a massive gap. But the real cost difference comes from how each program treats mortgage insurance on low-down-payment loans.
With FHA and 3.5% down, you pay a 1.75% upfront MIP (typically rolled into the loan) plus 0.55% annual MIP for the life of the loan. With conventional and 5% down, you pay PMI based on your credit score — which could be lower or higher than FHA's MIP depending on your score. The critical advantage of conventional is that PMI automatically terminates once your loan balance hits 78% of the original appraised value.
Both programs allow your down payment to come from gift funds. FHA allows 100% of the down payment to be gifted from a family member. Conventional loans also allow gifts, though some programs require the borrower to contribute at least a portion from their own funds if the down payment is under 20%.

Mortgage insurance is the factor that separates short-term affordability from long-term cost — and it is where conventional loans have their biggest structural advantage.
FHA mortgage insurance has two components. The upfront MIP of 1.75% gets added to your loan balance at closing. On a $220,000 loan, that is $3,850 added to what you owe. Then you pay annual MIP of 0.55% split into monthly installments — about $101 per month on that same loan. If you put less than 10% down, this monthly MIP never goes away unless you refinance out of the FHA loan entirely.
Conventional PMI works differently. There is no upfront premium. Your monthly PMI rate depends on your credit score and loan-to-value ratio, and it cancels automatically once your loan balance reaches 78% of the original appraised value. You can also request early cancellation at 80% based on a new appraisal. For a borrower with a 720 credit score and 10% down, conventional PMI might run just 0.30% annually — about $55 per month on a $220,000 loan, compared to FHA's $101.
Over a 7-year period (the average time a Louisiana homeowner keeps their mortgage before selling or refinancing), a conventional borrower with decent credit can save $8,000 to $15,000 in total mortgage insurance costs compared to FHA. That is real money, and it is the main reason I recommend conventional whenever a buyer's credit score supports it.
How Do Appraisal Requirements Differ — and Why Does That Matter in Louisiana?
This is where Louisiana's housing stock creates a real practical difference between the two programs. FHA appraisals must follow HUD's Minimum Property Standards, which go beyond simply estimating the home's market value. FHA appraisers are required to identify health and safety deficiencies and conditions that affect structural soundness.
In Louisiana, where over 40% of housing units were built before 1980 according to Census Bureau data, this matters a lot. Common FHA appraisal flags on Louisiana homes include peeling or chipping exterior paint on pre-1978 homes (potential lead paint), aging electrical panels with outdated wiring, foundation settling in clay-heavy soils across Calcasieu and Jefferson parishes, missing or damaged handrails on elevated homes, and roof conditions that do not meet the three-year remaining life requirement.
When an FHA appraiser flags these items, they become required repairs — the seller must fix them before the loan can close, or the deal falls through. In fast-moving markets like Baton Rouge or the Northshore, sellers with multiple offers may simply reject the FHA buyer in favor of a conventional offer that comes with fewer appraisal hurdles.
Conventional appraisals are simpler. The appraiser's primary job is to confirm the property's market value supports the purchase price. Unless there are extreme safety hazards, conventional appraisals do not require the seller to make repairs. This gives conventional buyers an edge when competing for older homes in established neighborhoods across Louisiana — places like the Garden District in New Orleans, historic Lake Charles neighborhoods, or older Baton Rouge subdivisions near LSU.
When Does FHA Come Out Ahead?
FHA is the clear winner in several common scenarios. If your credit score is between 580 and 659, FHA will almost always offer a lower rate and more favorable mortgage insurance pricing than conventional. FHA's mortgage insurance rate does not penalize lower scores the way conventional PMI does.
FHA also wins when your debt-to-income ratio is high. FHA allows DTI ratios up to 56.99% with strong compensating factors, while most conventional programs cap at 50%. In Louisiana, where property insurance premiums average over $3,000 per year and flood insurance can add another $1,000 to $3,000 annually, DTI room matters. A buyer in Lake Charles or Houma who is paying $400 per month in combined insurance premiums needs every bit of DTI flexibility they can get.
FHA also works well for buyers recovering from past credit events. The waiting period after a Chapter 7 bankruptcy is just two years with FHA, compared to four years for conventional. After a foreclosure, FHA requires a three-year waiting period versus seven years for conventional.
Finally, FHA can be better for buyers who plan to sell or refinance within three to five years. If you are not keeping the loan long enough for the PMI-cancellation benefit of conventional to matter, FHA's lower upfront rate and more accessible qualification standards may give you a cheaper path into the home.
When Does Conventional Come Out Ahead?
Conventional wins for buyers with credit scores above 680, particularly when they can put at least 5% to 10% down. The PMI savings alone can make conventional the cheaper option by hundreds of dollars per year — and once PMI drops off, the gap widens dramatically.
If you are buying an older Louisiana home — and there are plenty of them — conventional's less restrictive appraisal requirements can be the difference between closing and losing the deal. Sellers in competitive markets increasingly prefer conventional offers because they are less likely to hit appraisal-related repair requirements.
Conventional also wins when you are putting 20% or more down. At that point, there is no PMI at all, and FHA's mandatory MIP makes it strictly more expensive. Buyers using equity from a previous home sale or who have saved aggressively should always go conventional in this scenario.
For investment properties or second homes, conventional is your only option — FHA requires owner occupancy. And if you plan to stay in the home long-term, the ability to eliminate PMI at 20% equity gives conventional a significant lifetime cost advantage. On a $250,000 loan, eliminating PMI at the 20% equity mark saves roughly $25,000 to $40,000 over the remaining life of a 30-year loan compared to carrying FHA MIP the entire time.
What Louisiana-Specific Factors Should You Consider?
How Do Louisiana Insurance Costs Affect the Decision?
Louisiana homeowners insurance rates are among the highest in the nation — the average annual premium is approximately $4,200, nearly three times the national average. In coastal parishes like Cameron, Calcasieu, Terrebonne, and Lafourche, premiums can exceed $6,000. Add flood insurance for properties in FEMA-designated zones, and total annual insurance costs can reach $8,000 to $10,000.
These insurance costs are included in your qualifying debt-to-income ratio. Higher insurance premiums reduce the purchase price you can qualify for. Because FHA allows higher DTI ratios than conventional, buyers in high-insurance areas may qualify for more home with FHA — or may only qualify with FHA and not conventional at all.
How Do Older Homes and Flood Zones Change the Equation?
Louisiana has the eighth-oldest housing stock in the South, with a significant number of homes built before modern building codes. If you are looking at homes in established neighborhoods across Lafayette, Shreveport, Monroe, or Alexandria, you are likely considering properties that are 30 to 60 years old.
These homes are more likely to trigger FHA appraisal issues — but they also tend to be more affordable and located in desirable, established neighborhoods. The practical impact is that FHA buyers sometimes get shut out of specific properties, not because they cannot afford them, but because the appraisal process creates friction that sellers do not want to deal with.
For flood zone properties, both loan types require flood insurance, and both count it toward your qualifying payment. The difference is in the appraisal treatment — FHA may flag flood-related property conditions that conventional appraisers overlook.
What Is the Crossover Point Where Conventional Becomes the Better Deal?
Based on the loans we originate at Bayou Mortgage, the crossover point where conventional starts saving borrowers money typically falls around a 680 credit score with 5% to 10% down. Below that credit range, FHA's flat mortgage insurance pricing and more flexible qualification guidelines make it the better value. Above that range, conventional's lower PMI rates and the ability to cancel PMI make it cheaper over time.
Here is a real-world example. Take a $240,000 purchase price in Sulphur, Louisiana. With 5% down ($12,000), the loan amount is $228,000.
- FHA at 640 credit: 6.75% rate, $101/month MIP (never cancels), $1,478 base P&I. Total first-year housing payment including insurance: approximately $2,185/month.
- Conventional at 640 credit: 7.125% rate, $185/month PMI (cancels at 80% LTV), $1,536 base P&I. Total first-year housing payment: approximately $2,428/month.
- Conventional at 720 credit: 6.50% rate, $62/month PMI (cancels at 80% LTV), $1,441 base P&I. Total first-year housing payment: approximately $2,210/month.
At 640 credit, FHA saves this buyer $243 per month. At 720 credit, conventional saves $25 per month from day one — and once PMI drops off in roughly 8 to 9 years, the monthly savings jump to nearly $90. Over a 30-year term, the 720-credit conventional borrower saves over $18,000 compared to the same buyer on FHA.
The Bottom Line
There is no universal winner between conventional and FHA in Louisiana. If your credit score is below 660, FHA likely saves you money and gives you more flexibility. If your score is above 700 and you can put at least 5% down, conventional is almost always the better long-term deal because of PMI cancellation. In the 660-700 range, run the numbers on both — the answer depends on your specific down payment, DTI, and how long you plan to keep the loan. At Bayou Mortgage, we quote both programs side by side on every file so you can see exactly which one costs less for your situation.
Frequently Asked Questions
Can I switch from FHA to conventional later?
Yes. Many Louisiana borrowers start with FHA and refinance into a conventional loan once they build 20% equity or improve their credit score, eliminating mortgage insurance entirely.
Is FHA always cheaper than conventional for first-time buyers?
Not always. If your credit score is 700 or higher and you can put 5% down, conventional often costs less over time because PMI drops off automatically at 20% equity.
Do conventional loans have stricter appraisal requirements than FHA?
It is the opposite. FHA appraisals require the property to meet HUD minimum property standards, which flag issues like peeling paint and faulty wiring. Conventional appraisals focus primarily on market value.
What credit score do I need for a conventional loan in Louisiana?
Most lenders require a minimum 620 credit score for conventional loans. However, you will get better rates and lower PMI costs with a score of 740 or above.
Does Louisiana have higher FHA loan limits than other states?
Most Louisiana parishes use the national baseline FHA limit of $524,225 for a single-family home. This covers the majority of home purchases across the state.
