Property Tax Rate: How Much It Varies and Why It Matters

Property tax rate is the annual property tax as a percentage of assessed value. It is the largest operating expense on most rentals after management, and it varies more between states than almost any other number in a deal.

The formula

Annual property tax = Assessed value x tax rate

Assessed value is not always market value. Some states assess at full market value, others at a fixed fraction of it, and the headline rate means little without knowing which.

How much it varies

Effective rates (tax as a share of actual market value) range from well under 0.5% in parts of the South and West to over 2% in several Northeast and Midwest states. On a US$150,000 house that is the difference between roughly US$600 and US$3,300 a year, or about US$225 a month of cash flow.

That gap is large enough to decide whether a property works. A 1% rent-to-price ratio in a 2.2% tax state is frequently a worse deal than 0.85% where tax is 0.6%.

Reassessment is the trap

This catches out-of-state buyers constantly. The tax figure on a listing is what the current owner pays, which may reflect:

• An assessment from years ago, in a market that has since risen
• A homestead exemption you will lose, because you will not live there
• A senior, veteran or long-term-owner exemption that does not transfer

A sale often triggers reassessment at the new purchase price. A house showing US$1,200 a year in tax can become US$2,600 the year after you buy, purely because it is now assessed at what you paid and you do not qualify for the owner-occupier exemption.

How to verify it

• Look up the parcel on the county assessor or treasurer's site. These are public and usually searchable by address.
• Find the current assessed value and the total millage rate, including school and municipal levies.
• Recalculate at your purchase price rather than the current assessment.
• Ask explicitly which exemptions are on the parcel and whether they survive a sale.
• Confirm with a local agent or manager what post-sale reassessment normally does in that county.

Budget the reassessed figure. If the deal only works at the seller's tax bill, it does not work.
