County figures are the Mississippi average adjusted for local market conditions. Actual rates vary by lender, credit score, and loan size.
In Harrison County, property tax runs 0.58% of home value — $111/mo on the $228,658 median home. Low carry cost changes the math in your favor: your PITI leaves 10 points of DTI headroom versus the 43% ceiling before you account for other debt.
That headroom is a real asset. It's what lets you hold the 30-year fixed term instead of stretching to an ARM to afford the payment — the fixed-rate cost delta is roughly $86/mo on this loan size, and low-tax counties are where locking it costs you the least. Insurance still varies by zip ($160/mo here), but on the tax line you have no reason to compromise on term or rate structure.
Low tax burden in Harrison County means your DTI has room to work
Your PITI sits about 10 points under the 43% ceiling — that's buying power. Lock the 30-year fixed and match against lenders that price low-tax-county files well.
