How Much House Can You Afford in the 337? A 2026 Home Affordability Guide for Acadiana
At Lafayette Parish's August 2026 median sale price of about $255,000 and a 6.95% rate, plan on $2,150–$2,230 a month with 0%–5% down once property taxes, homeowners insurance, flood coverage, and mortgage insurance are included. Lenders may approve that at about $68,000–$70,000 of household income; a comfortable budget takes $92,000–$96,000.

One of the first questions buyers ask me is, "How much house can I actually afford?" In Acadiana, the answer looks different than it does in big metro areas. Our home prices are friendlier, but Louisiana adds costs that national mortgage calculators often leave out, especially insurance. This guide walks through the real monthly numbers, what lenders look for, and what your budget buys in Lafayette, Youngsville, Broussard, Breaux Bridge, and the surrounding parishes.
How much does a median-priced Lafayette Parish home cost per month in 2026?
A home at Lafayette Parish's August 2026 median price costs about $2,150 to $2,230 a month with 0% to 5% down, or about $1,800 with 20% down. Here's the full breakdown on a $255,000 home, including the Louisiana costs that make the biggest difference.
| FHA, 3.5% down | Conventional, 5% down | Conventional, 20% down | USDA, 0% down | |
|---|---|---|---|---|
| Down payment | $8,925 | $12,750 | $51,000 | $0 |
| Loan amount (including financed upfront fees) | $250,381 | $242,250 | $204,000 | $257,550 |
| Principal and interest | $1,657 | $1,604 | $1,350 | $1,705 |
| Mortgage insurance | $113 | $101 | $0 | $74 |
| Property taxes (with homestead exemption) | $132 | $132 | $132 | $132 |
| Homeowners insurance (estimate) | $250 | $250 | $250 | $250 |
| Flood insurance (Lafayette Parish NFIP average) | $67 | $67 | $67 | $67 |
| Estimated total monthly payment | $2,219 | $2,154 | $1,800 | $2,228 |
| Income a lender may approve (45% total DTI, $400 in other monthly debt) | $69,900 | $68,100 | $58,700 | $70,100 |
| Comfortable income (housing at 28% of gross income) | $95,100 | $92,300 | $77,100 | $95,500 |
| Closing costs to budget (2%–5%) | $5,100–$12,750 | $5,100–$12,750 | $5,100–$12,750 | $5,100–$12,750 |
Estimates only, not a loan approval. Assumes a 30-year fixed rate of 6.95% for every loan type (FHA and USDA rates often differ). FHA: 1.75% upfront premium financed, 0.55% annual premium. USDA: 1% upfront fee financed, 0.35% annual fee. Conventional PMI assumed at 0.5% per year; yours depends on credit score. Property taxes use 2025 unincorporated Lafayette Parish millage (88.29 mills) with the homestead exemption; homes inside City of Lafayette limits add about $36 a month. Homeowners insurance assumed at $3,000 per year. Flood uses the Lafayette Parish NFIP average of $801 per year; homes outside high-risk zones may not require a policy. Totals may differ by $1 due to rounding.
Why do national mortgage calculators underestimate Louisiana payments?
In the 5%-down example above, homeowners insurance and flood coverage add $317 a month, about 15% of the total payment. Many national calculators use a generic insurance figure or skip flood entirely. Louisiana insurance estimates also vary widely: published 2026 statewide averages range from about $1,968 to $7,304 a year depending on the source and coverage assumptions. The only number that counts is a real quote on the specific house.
Three rules of thumb help put these costs in perspective at today's rate:
- Every $1,000 a year in insurance costs about $83 a month, the same as borrowing roughly $12,600 more.
- Every $10,000 you borrow adds about $66 a month in principal and interest at 6.95%.
- On a $242,250 loan, each 1 percentage point of interest rate changes the payment by about $160–$166 a month.
What debt-to-income ratio do Louisiana mortgage lenders allow?
Your debt-to-income ratio (DTI) is your total monthly debt payments, including the new house payment, divided by your gross monthly income. If your debts total $2,400 and you earn $6,000 a month before taxes, your DTI is 40%. The limit depends on the loan type and on whether the file is approved by automated underwriting.
| Loan type | Guideline | How much flexibility |
|---|---|---|
| Conventional | About 36% total DTI for manual underwriting; up to 45% with compensating factors | Fannie Mae's Desktop Underwriter can approve up to 50% |
| FHA | 31% housing, 43% total | Automated approvals can go well above 43% with strong credit and reserves |
| VA | 41% total as a benchmark | Residual income (money left after expenses) matters more than DTI |
| USDA | 29% housing, 41% total | Modest room above that for well-qualified files |
Lenders also review your credit score, two years of employment history, and the savings you'll have left after closing. Qualifying for a payment and being comfortable with it are two different numbers, which is why the example above shows both.
How much do I need for a down payment in Acadiana?
You do not need 20% down to buy a home in the 337. Here's what each loan type requires on a $255,000 home.
| Loan type | Minimum down | Cash for down payment | Mortgage insurance |
|---|---|---|---|
| VA (eligible veterans and service members) | 0% | $0 | No monthly mortgage insurance; a one-time funding fee applies unless you're exempt |
| USDA (eligible address and income) | 0% | $0 | 1% upfront fee plus 0.35% a year |
| Conventional | 3%–5% | $7,650–$12,750 | PMI until you reach 20% equity; it ends automatically at 22% |
| FHA (580+ credit score) | 3.5% | $8,925 | 1.75% upfront plus 0.55% a year; lasts the life of the loan with less than 10% down, or 11 years with 10% or more |
A bigger down payment lowers your monthly payment and your mortgage insurance. In the example above, going from 5% to 20% down saves about $354 a month, but it takes $38,250 more in cash. Putting 10% to 15% down can lower your PMI cost without emptying your savings.
Alyson's tip: Aim for a balance between comfort and opportunity. Don't drain your savings to hit a bigger down payment. Life happens, whether it's a new AC unit in July or furniture for the new place. Owning a home should feel exciting, not stressful. You don't want to be house broke!
Is USDA financing available in Lafayette, Youngsville, and Breaux Bridge?
Often, yes, outside the city core. USDA eligibility is set address by address. Roughly 58% of Lafayette Parish's land area falls inside USDA-eligible boundaries, and communities such as Youngsville, Broussard, Scott, Carencro, and Duson include eligible areas. Addresses inside Lafayette city limits typically don't qualify. For 2026, the household income limit in most Louisiana parishes is about $110,650 for households of one to four people. Check any address on USDA's eligibility map before you fall in love with a house.
Is there down payment assistance in Lafayette and Acadiana?
- Louisiana Housing Corporation (LHC): The MRB Assisted program provides 4% assistance, and the MRB Home program provides 5% to 9% depending on the loan amount. Income limits, credit minimums, and a homebuyer education course apply.
- Lafayette Consolidated Government (LCG): LCG runs a first-time homebuyer assistance program and free one-on-one housing counseling. Through a partnership with Southern University, eligible low-income families can open a matched savings account that adds $4 for every $1 saved, up to $4,000.
- Seller concessions: Sellers can contribute toward your closing costs. FHA allows up to 6% of the price.
What do homes cost in Lafayette, Youngsville, Broussard, and Breaux Bridge right now?
Prices vary a lot across Acadiana. A buyer priced out of Youngsville may find the same budget goes much further in Breaux Bridge or Iberia Parish.
| Area | August 2026 median | 12-month range of monthly medians |
|---|---|---|
| Youngsville | $314,200 | $265,000–$314,200 |
| Broussard | $287,972 | $269,000–$331,650 |
| Lafayette Parish (all) | $254,679 | $247,999–$266,500 |

| Iberia Parish | $221,250 | $146,500–$221,250 |
| Vermilion Parish | $212,439 | $203,000–$233,963 |
| Breaux Bridge | $185,000 | $155,000–$272,000 |
| Acadia Parish | $175,000 | $140,250–$225,500 |
| St. Martin Parish (all) | $170,500 | $150,000–$230,750 |
Based on information from the REALTOR® Association of Acadiana MLS for residential sales, September 2025 through August 2026. Monthly medians in smaller markets swing widely because each month has fewer sales. Data is deemed reliable but not guaranteed.
What does my budget buy in Acadiana?
Every buyer and every house is different, but here's what I typically see at each price point:
- Around $200,000: Below the Lafayette Parish median. Expect smaller starter homes, townhomes or condos in Lafayette, and older homes in established neighborhoods. In Breaux Bridge, St. Martin Parish, and Acadia Parish, this budget sits near the middle of the market.
- Around $300,000: Newer construction, larger lots in nearby parishes, and updated homes in popular Lafayette communities. This is close to the typical sale price in Youngsville and Broussard.
- $400,000 and up: Semi-custom builds, larger floor plans, newer amenities, and sought-after school zones.
What other costs should Acadiana homebuyers budget for?
| Cost | Typical range | What to know |
|---|---|---|
| Homeowners insurance | Varies widely by house and carrier | Get quotes during your inspection period, before you're locked in. A FORTIFIED roof can lower the wind and hurricane portion of your premium, and Louisiana will require insurers to discount it starting January 1, 2027. Ask sellers if the roof has a FORTIFIED certificate. |
| Flood insurance | Lafayette Parish NFIP average $801 a year | Required for high-risk zones (A and AE) with a federally backed mortgage. Only about 1 in 5 Lafayette Parish households carries NFIP coverage, even though the August 2016 flood showed water doesn't follow map lines. |
| Termite contract | About $180–$500 a year to renew | Formosan termites make an active termite contract standard here. Many purchase contracts and lenders call for a Wood Destroying Insect report before closing. |
| Property taxes | About 0.63%–0.80% of value in Lafayette Parish with homestead | Rates vary by parish and city limits. See my 2026 Louisiana property tax guide for how bills are calculated. |
| Closing costs | 2%–5% of the price | Louisiana has no statewide transfer tax, but lender, title, notary, recording, and prepaid escrow costs add up. |
| HOA dues | Varies by neighborhood | Common in newer Youngsville, Broussard, and south Lafayette subdivisions. Count them in your DTI. |
Also plan for lawn care and drainage upkeep, higher utility bills in older homes, and commute costs if you work in Lafayette but live in a surrounding parish.
How do I get pre-approved for a mortgage in Acadiana?
Pre-approval tells you your real budget before you shop, so you don't fall in love with a house outside your range.
- Gather your documents: recent pay stubs, two years of W-2s or tax returns, and two months of bank statements.
- Talk to a local lender who knows parish tax rates, flood zones, and USDA boundaries, and ask them to include real taxes and insurance in your estimate.
- Check assistance options such as LHC programs, LCG's homebuyer program, or USDA eligibility before you pick a loan type.
- Get your pre-approval letter and set your own comfortable payment, which may be lower than the maximum you're approved for.
- Get insurance and flood quotes early on any home you're serious about.
Alyson's take: part math, part lifestyle, part trusting your heart
Figuring out how much home you can afford in the 337 comes down to three things: the math, how you want to live, and what feels right for your family. The biggest surprise I see with first-time buyers isn't the price of the house. It's the insurance quote. That's why I encourage every buyer to get real insurance and flood numbers early, before they fall in love with a house.
If you're ready to explore what your budget can unlock in Lafayette, Youngsville, Broussard, or Breaux Bridge, I'm here to help. I can connect you with local lenders who will run your real numbers.
Frequently asked questions
How much income do I need to buy a median-priced home in Lafayette Parish?
With 5% down on a $255,000 home at 6.95%, the full payment is about $2,154 a month, including taxes, insurance, flood coverage, and PMI. Lenders may approve that with about $68,100 in household income if you carry $400 in other monthly debt. Keeping housing at 28% of gross income takes about $92,300.
Do I need 20% down to buy a house in Louisiana?
No. VA and USDA loans allow 0% down, conventional loans start at 3% down, and FHA loans require 3.5% down with a 580 credit score. Putting less than 20% down means paying mortgage insurance. Louisiana Housing Corporation programs can provide 4% to 9% in down payment assistance for eligible buyers.
Is flood insurance required when buying a home in Lafayette?
It's required if the home is in a high-risk flood zone such as A or AE and you use a federally backed mortgage. It's optional in lower-risk zones, but many Acadiana buyers carry it anyway. The average NFIP policy in Lafayette Parish costs about $801 a year.
Can I buy a home in Acadiana with no money down?
Yes, if you qualify for a VA loan or buy a USDA-eligible home. USDA requires an eligible address and household income under about $110,650 for a household of one to four people in most Louisiana parishes. You'll still need money for closing costs unless seller concessions or assistance programs cover them.
