Learn moreHousing pricier than Mississippi's statewide figures, still below national norms
Diamondhead's own housing figures ran approximately $246,500 to $269,853 as of mid-2026 depending on measure -- above Mississippi's own statewide typical-value figures, though still below the roughly $355,000-$375,000 range typically cited nationally (base record).
A 1.25% effective property tax rate, above the national median
Diamondhead's own 1.25% effective property tax rate (Ownwell) runs above the national median (1.02%) but below Ownwell's own cited Mississippi state median (1.35%) -- confirm a specific property's current combined millage directly with the Hancock County Tax Assessor (base record).
Notably low homeowners insurance for a Mississippi Gulf Coast city
Diamondhead's own homeowners-insurance figures (approximately $825-$1,907/year) run genuinely, notably below both Mississippi's statewide $2,514-$5,161/year range and the Gulfport-Biloxi metro's approximately $7,459/year figure, plausibly reflecting Diamondhead's set-back, north-of-I-10 location (base record).
Mississippi's 4.0% flat income tax and full retirement-income exemption
Mississippi's real, current flat 4.0% individual income tax rate (2026), with a further legislated path toward 3% by 2030, and its full exemption of Social Security, 401(k)/IRA, and pension income from state tax apply in Diamondhead as they do statewide -- a real, distinctive benefit for Diamondhead's genuine retiree-community identity (base record).
