There’s a tidy piece of advice that gets passed around: budget 1% of your home’s value each year for maintenance. On a $400,000 house, that’s $4,000 a year, or about $333 a month set aside for the upkeep the house is going to demand whether you plan for it or not.
It’s a fine starting point. It’s also, for a lot of New Hampshire homes, on the low side. Here’s how to think about the real number.
Where the rule comes from, and where it breaks
The 1% rule is a rough average across all homes, everywhere. But the actual figure moves with two things the rule ignores: how old the house is, and how hard the climate is on it. A five-year-old home in a mild climate might genuinely run half a percent. A twenty-year-old home in a place with real winters runs a lot more.
Which is why the better guidance is a range: budget somewhere between 1% and 4% of your home’s value per year, leaning higher for older homes and harsh weather. New Hampshire checks both boxes. We have old housing stock and a climate that freezes, thaws, and dumps snow on your roof for months. That’s a 2% to 4% situation for a lot of houses here, not 1%.
What people actually spend
To ground it: recent data puts the average household at around $2,458 a year in routine maintenance, plus roughly $2,321 in emergency repairs. Add those up and the “average” home is spending close to $4,800 a year, and notice that nearly half of it is emergencies.
That second number is the one to pay attention to, because it’s the one you can shrink.
The whole point of budgeting is moving money out of the emergency column
Emergency repairs cost more than the same work done on a schedule. A water heater you replace because you noticed the warning signs is a planned expense. The same water heater that fails and floods the basement is that expense plus water damage, and water damage claims average around $14,000. We wrote about that trap in small leaks, big bills.
Planned maintenance is simply cheaper than reactive maintenance. That’s the entire argument for setting the money aside and actually spending it on upkeep.
How to split it
A simple way to hold the budget:
- Set aside monthly. Take your target percentage, divide by twelve, and treat it like any other bill.
- Spend part of it on prevention. Seasonal service, the caulk-and-weatherstripping basics, gutter and filter changes. This is what keeps the emergency column small.
- Let the rest accumulate for the big-ticket items you know are coming: roof, heating system, water heater, paint.
Or don’t hold the whole thing in your head
The honest reason most homes drift into deferred maintenance isn’t money, it’s that nobody’s tracking what needs doing when. That’s the part we take off people’s plates. A regular maintenance plan with Dovetails Home Services turns “I should probably get to that” into a scheduled visit, which is exactly how you keep spending in the cheap column.
