New to this? Quick definitions
- Effective tax rate —
- what you actually pay in property tax as a % of your home's value each year, after any local exemptions.
- Assessed value vs. market value —
- market value is what a buyer would pay; assessed value is the number your county uses to calculate your tax bill, which may lag market value.
- Mill rate —
- another way some counties express the tax rate — dollars owed per $1,000 of assessed value. It converts to the same effective rate.
- Homestead exemption —
- a discount some states offer on the assessed value of your primary residence, which lowers your tax bill. You usually have to apply for it.
- Escrow —
- after you close, an ongoing account your lender manages that collects a slice of your property tax (and insurance) with every mortgage payment, then pays the county for you.
- Reassessment —
- when the county updates your home's assessed value — often triggered by a sale, renovation, or a routine cycle — which can raise (or lower) your tax bill.

Mistakes first-time buyers make
- Assuming the seller's current tax bill is what you'll pay — reassessment at your purchase price often raises it.
- Not checking whether the county offers a homestead exemption, then forgetting to apply for it after closing.
- Missing the appeal deadline window — most counties only give you 30-90 days after your assessment notice arrives.
- Comparing homes across counties using the statewide average rate instead of each county's actual rate.
Pro tips
- Ask your agent for the exact county effective tax rate before you write an offer — not the statewide average.
- Calculate what your bill would be after reassessment at your actual purchase price, not the seller's old assessed value.
- Mark your calendar for the appeal deadline the day you get your first assessment notice — it's easy to miss.
- If New Hampshire offers a homestead exemption, apply for it right after closing — it usually isn't automatic.
