County figures are the Ohio average adjusted for local market conditions. Actual rates vary by lender, credit score, and loan size.
In Franklin County, property tax runs 1.40% of home value — $352/mo on the $301,340 median home. Low carry cost changes the math in your favor: your PITI leaves 0 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 $113/mo on this loan size, and low-tax counties are where locking it costs you the least. Insurance still varies by zip ($125/mo here), but on the tax line you have no reason to compromise on term or rate structure.
Low tax burden in Franklin County means your DTI has room to work
Your PITI sits about 0 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.
