In Merrimack County, property tax runs 1.80% of home value — $748/mo on the $498,871 median home. That's not a footnote; it's 19% of the PITI total before you finance anything.
Run the same home with 10% down and your payment includes $262/mo of PMI on top. Combined: $4,036/mo — and on an $80,000 household income, that lands a 68.0% back-end DTI, above the 43% conventional ceiling.
What this means in practice: in high-tax counties, the tax bill, not the rate, is what breaks your qualification. The lever that fixes it is usually the down payment — every 5 points of down payment removes roughly $263/mo and pulls DTI down by 3.9 points. The second lever is loan type: FHA underwrites to 57% back-end.
Your Merrimack County payment already includes $748/mo in property tax
And if you're putting down less than 20%, PMI adds $262/mo on top. Run your income through the DTI gauge: if it's over 43%, most conventional lenders stop the conversation there. You don't want to find that out at underwriting.
Two moves keep you in the game: a larger down payment, or a lender that writes high-DTI files. FHA caps at 57%, and some licensed lenders offer PMI-reduction programs. Match your profile against lenders rather than picking one on brand.
