Getting the keys is supposed to be the finish line. For a lot of buyers, it's where the budget starts to hurt.
A recent LendingTree poll found that 59% of homeowners feel "house poor," and half of those surveyed said they had missed at least one mortgage payment in the past year. The loan itself is only part of the problem. Zillow puts the cost of maintenance, insurance and property taxes at about $1,380 a month nationally, up nearly 32% in five years.
Those national numbers are a useful warning. Here in Dane County, one of them is a lot bigger.
Property taxes: the big one in Dane County
The national story pegs the average property tax bill at $3,129 a year. In Madison, it's about two and a half times that. According to the City of Madison Finance Department, the average Madison home was valued at $457,300 for 2025, and its total tax bill after state credits was $7,743. That's about $645 a month before you pay a dollar of principal or interest.
It's not just the city. Census data compiled by the Badger Institute showed Dane County with the largest median property tax bill of Wisconsin's large counties in 2023, about $6,170, at an effective rate of 1.57%.
What to do about it:
- Look up the actual tax bill. Don't rely on a rough estimate. Tax bills are public, and we pull them for every home our buyers consider.
- Check what's behind the number. If the home was a rental, last year's bill may not reflect the Lottery and Gaming Credit, which applies only to a primary residence. If it's new construction, last year's bill may cover only the lot, and your first full bill will be much higher.
- Know how appeals work in Wisconsin. You can't appeal the tax bill itself. You can challenge your assessed value. Each spring, after assessment notices go out, municipalities hold Open Book, where you can review your assessment with the assessor informally. If that doesn't settle it, you can object to the Board of Review. The Wisconsin Department of Revenue requires you to give notice of your intent to object at least 48 hours before the board's first meeting, and your written objection must include your own estimate of value. The assessor's value is presumed correct, so bring evidence such as recent comparable sales. Dates vary by municipality, so watch for your notice.
Insurance: get a quote before you write an offer
Insurance is the fastest-rising housing cost in the national data, though Wisconsin is still cheaper than most of the country. NerdWallet's 2026 figures put the average Madison policy at about $2,300 a year and the Wisconsin average at $2,465, about 18% below the national average.
Average isn't your number. The age of the roof, the home's construction, your claims history and your deductible all move the price. Get a quote on the specific property before you write an offer, not after, and get more than one. Shopping around is one of the easiest ways to keep this cost down.
Maintenance: the cost nobody puts in the listing
Zillow estimates maintenance at about $11,171 a year nationally, and it varies widely by home. A common rule of thumb is to set aside about 1% of the home's value each year. On the average Madison home, that's roughly $4,600 a year, or about $380 a month.
Older homes, which are common in Madison's established neighborhoods, can run higher. Think furnace, water heater, roof and windows. A good inspection tells you which of those is near the end of its life, so you can budget for it or negotiate before closing. Condos and newer construction usually carry less upkeep, though association dues belong in the budget too.
The escrow surprise
Many buyers pay taxes and insurance through an escrow account built into the mortgage payment. That's convenient, but it means the payment changes whenever either one goes up. Half of LendingTree's respondents saw their monthly payment rise over the past two years. A fixed-rate loan doesn't mean a fixed payment.
What it adds up to
On the average Madison home, property taxes, insurance and a 1% maintenance reserve come to about $14,600 a year. That's roughly $1,220 a month on top of principal and interest, and it's the number to plan around.
Buy the payment you can live with
Getting approved for a payment and being comfortable with it are two different things. Before you fall for a house, run the full monthly cost: principal and interest, the real tax bill, an insurance quote and a maintenance reserve.
