You've run the numbers on a Louisiana rental twice now, once with the state's flat 3% income tax penciled in as a clean win over a graduated-tax state, and once without. Both times the deal looked fine on paper. What neither pass accounted for is the line item that actually decides whether a Louisiana rental works: insurance, not once but twice, because a standard policy never covers the flood risk that comes standard with owning property in large parts of this state.
Louisiana's statewide median hit $335,000 in the most recent read, with New Orleans running hotter at $354,000 over the three months ending May 2026, up 5.7% year over year (Redfin). We first ran these numbers back in June; this update refreshes the pricing and rates and adds Shreveport to the mix. The short version: the tax picture genuinely favors investors, and it still isn't enough.
New Orleans: the insurance bill rivals the mortgage
At New Orleans' $354,000 median with 25% down and a 6.58% rate, principal and interest runs about $1,692 a month. Orleans Parish's homestead exemption wipes out tax on the first $75,000 of value for an owner-occupant, but a rental gets none of it, pushing the effective investor property tax rate to roughly 0.88% of value, about $260 a month. That's the easy part. Landlord insurance in Louisiana has historically averaged $2,224-$2,484 a year excluding flood (Steadily/RentCafe, verified in June), which is $207 a month at the higher end, but a fresh pull today from Insure.com shows New Orleans landlord-specific policies now running as high as $9,251 a year, nearly four times that figure. That gap is too large to be six weeks of market movement and more likely reflects a difference in coverage assumptions between the two sources, so we're using the more conservative, previously-verified $207-a-month figure here and flagging the wide range for you to confirm with a bound local quote before underwriting a deal.
Then there's flood. Large sections of New Orleans sit below sea level, and unless a specific parcel is confirmed Zone X, assume high-risk AE or VE pricing of $333-$500-plus a month. Using $400 a month, New Orleans' PITI lands near $2,559, against a 3-bedroom single-family rent of $1,863 (Steadily, 2026). That's a DSCR of about 0.73 and, after an 8% management fee and one month's vacancy, a cash flow of roughly negative $988 a month. Add the $207 conservative insurance figure to the $400 flood premium and you get a combined $607 a month in insurance alone, on a property where the mortgage itself is $1,692. For you, the practical read is that no amount of rate-shopping the mortgage fixes the New Orleans math, because the number actually sinking the deal is sitting in the insurance line, not the rate or the tax bill.
Baton Rouge: passes DSCR, still loses money
Baton Rouge shows the split-personality pattern that recurs across half the states we've underwritten this year. At its Zillow-tracked median of roughly $224,000 (down 1-2% year over year, a softer read than the $237,000 Redfin figure from our June pass), 25% down and 6.58% financing put principal and interest near $1,071 a month. East Baton Rouge Parish's investor property tax rate runs about 0.70% of value, or $131 a month. Against a 3-bedroom SFR rent of $1,695 (RentCafe, 2026) and a moderate flood assumption of $200 a month for a parish that's a mix of high ground and floodplain, PITI comes to roughly $1,587, a DSCR of 1.07, technically a pass. Cash flow after management and vacancy still lands around negative $158 a month, because passing the lender's minimum ratio and clearing your own bank account are two different tests.
Move that same $224,000 property into one of Baton Rouge's confirmed Zone X high-ground suburbs, Zachary, Central, or Denham Springs, and the flood premium drops to zero. PITI falls to about $1,387, and cash flow after management and vacancy flips to roughly positive $42 a month. It's a thin margin, but it's the only submarket in this entire state that clears the bar in genuine, not just DSCR-technical, terms. If you're set on investing in Louisiana, the flood zone determination on a specific parcel matters more than the city it's in.
Shreveport: the cheapest insurance, the weakest rent
Shreveport, Lafayette, and Monroe carry the lowest homeowners insurance rates in Louisiana thanks to minimal hurricane and flood exposure this far from the coast (Insure.com, 2026). At Shreveport's $227,800 median, 25% down and 6.58% financing put principal and interest near $1,089 a month, an estimated 0.75% investor property tax rate at roughly $142 a month, landlord insurance around $236 a month, and a light $50-a-month flood allowance for what is mostly Zone X terrain. PITI comes to about $1,517. The problem is the rent side: at a citywide median of $1,025 a month, which likely blends in lower-yielding apartment stock and may understate true 3-bedroom single-family rent, DSCR comes in at just 0.68, and cash flow after management and vacancy runs roughly negative $653 a month, the worst dollar loss of the three cities relative to its price. Confirm actual 3-bedroom SFR asking rents with a local property manager before underwriting Shreveport; a citywide median that includes apartments is not the same number a single-family landlord actually collects.
Cheap insurance alone doesn't make a deal work if the rent never showed up to begin with, and Shreveport is the clearest example on the state's own map of why the price tag is only half the underwriting.

The tax advantage is real. It's just not the whole story
Louisiana's flat 3% income tax, effective January 1, 2025 and down from a graduated structure that topped out at 4.25%, is a genuine edge over comparable Southern states running graduated brackets at 5% or higher. It just isn't the line item that decides whether a Louisiana rental cash-flows, the way it might in a state with cheap, boring, no-surprises insurance. Here, insurance and flood coverage combined can run two to three times the size of the tax savings, which means an investor who only compares Louisiana's income tax rate against, say, Texas's property-tax-heavy, no-income-tax model is comparing the wrong line item entirely. Texas trades a higher property tax bill for zero income tax; Louisiana trades a low income tax and a genuinely low advertised property tax rate for an insurance bill that can quietly double the total carrying cost. For you, the lesson is to run the full PITIA, tax, insurance, and flood together, before letting one attractive-looking line item like a flat 3% rate carry the whole investment thesis.
This is the same insurance-driven pattern we found underwriting Florida this month, another Gulf Coast state where falling SFR insurance costs coexist with a completely separate, and much larger, coastal risk premium. If you're weighing Gulf Coast markets against each other, insurance exposure, not the state income tax column, is the number that should decide the comparison.
What this means for your next move
If you're set on Louisiana, the math points toward Baton Rouge's confirmed Zone X suburbs and away from New Orleans as a cash-flow play, full stop. A local property manager or a specialist familiar with parish-by-parish flood mapping is worth the referral fee before you write an offer, because the difference between AE and Zone X on the same street can be the entire margin between a $42-a-month winner and a $988-a-month loser. And if the insurance-and-flood combination in this state doesn't sit right with your risk tolerance, the low-property-tax, no-flood-risk profile of a state like Colorado is worth comparing before committing capital to the Gulf Coast specifically for its tax rate alone.
