Louisiana state average

$$114

$3,500/yr

Monthly tax is estimated on a $249,000 home — the price in the calculator above. Effective rates — U.S. Census Bureau, ACS 2024 (5-yr).

† Rates marked with ≥ are conservative estimates. ACS suppresses median tax values above $10,001 for privacy, which makes the calculated rate a lower bound — the true rate is higher in Manhattan, parts of Long Island, northern New Jersey and other high-cost areas.

How Louisiana compares

Louisiana's statewide average effective rate is 0.55% — the 39th highest of the 51 covered here (the 50 states and DC), against a median of 0.8%. On the $249,000 home the calculator starts with, that is about $114 a month in property tax before any other cost. Property taxes by state ranks all 51 with median bills attached.

A state average hides the part that changes the bill. The county rows above run from 0.15% in East Feliciana Parish to 0.83% in Orleans Parish (New Orleans) — roughly $141 a month apart on the same $249,000 home. That is why the county picker moves the payment more than the state picker does.

Insurance is the other line that follows the address: this page prices $3,500 a year as a state-level estimate, and home insurance by state covers how premiums are set and where they run highest. Below 20% down, PMI adds a third variable until the balance is back to 80% of the value.

The states nearest Louisiana in the ranking are Wyoming (0.57%) and West Virginia (0.53%).

Louisiana mortgage FAQ

How much down payment do I need to buy a house in Louisiana?

Conventional loans start at 3% down, but anything under 20% requires PMI until you reach 20% equity — PMI auto-cancels at 78% of the original home value under the Homeowners Protection Act. FHA loans start at 3.5% down, and VA / USDA loans offer 0% down for eligible borrowers. Those are the national minimums: a lender can set a higher floor for this state or for a given loan size.

Why do property taxes vary so much within Louisiana?

Property taxes are layered by county, city and school district, so the effective rate differs block by block. The Louisiana state average is about 0.55%, but counties in our table above range widely — always confirm the exact bill with the local County Assessor.

When does PMI go away?

Under the Homeowners Protection Act (1998) you can request PMI removal at 80% LTV, and lenders must automatically cancel it when the balance reaches 78% of the original home value. This calculator estimates that month for you and shows the lower payment after PMI drops.

Does this calculator include home insurance for Louisiana?

Yes. The calculator pre-fills a typical Louisiana premium of about $3,500 per year and updates it when you switch counties. Hurricane wind and flooding make Louisiana one of the hardest markets in the country — flood requires a separate NFIP or private policy, and insurer exits have raised premiums sharply.

Results are estimates for planning only and are not a loan approval. Property tax rates and insurance premiums vary by county, ZIP code, home age and coverage — confirm with the local County Assessor and insurer quotes. Rate default: Freddie Mac PMMS 30-yr fixed (7.32%, Oct 22 2026); the 20-yr default is an estimate derived from the PMMS 30-yr/15-yr spread (PMMS has no 20-yr series). Conventional credit pricing adds Fannie Mae loan-level price adjustments (effective 2026-10-01) on top of that base, anchored at the 740–759 tier, and PMI comes off a credit × LTV rate card — both are central estimates, not quotes. Loan minimums shown here are the national programs' floor; a lender may set a higher down payment, rate or fee for this state or this loan.
