Americans aren't moving. Here's what that does to your house.

The median American homeowner now stays in one house for about 12 years, according to a Redfin analysis reported in March 2026. In 2005, that figure was 6.5 years. It peaked at 13.4 years in 2020 and has settled near 12 since. The move-every-few-years rhythm that shaped how a generation thought about houses is gone, and that shift changes something most homeowners have not consciously updated: how much of the house's aging happens on your watch. Stay six years and you can plausibly hand the roof, the furnace, and the water heater to the next owner. Stay twelve and the odds flip. Systems will wear out, fail, and need replacing while you are still holding the keys.

How long do people actually stay now?

About 12 years at the median, per that Redfin analysis, up from 6.5 years two decades earlier. The reasons behind the shift are a tangle of housing market forces this post does not need to settle. What matters for you is the consequence. Twelve years is not a stopover. It is a third of a mortgage, most of a childhood, and a meaningful slice of the working life of nearly every system in the building.

When people stayed six or seven years, a house could quietly pass its problems down the line. The water heater that was eight years old at purchase became the next owner's emergency. The roof installed by the owner before last was always someone else's project. Short tenure let everyone rent the house's decline to a stranger. Long tenure ends the game of hot potato. Whatever is aging in your house is aging toward you.

What does twelve years do to a house?

Put the tenure number next to typical system lifespans and the picture sharpens. Tank water heaters typically last 8 to 12 years. Furnaces run roughly 15 to 20. Asphalt shingle roofs land roughly in the 15 to 30 year range, and major appliances roughly 10 to 15. All of these vary with climate, usage, and maintenance, but the shapes are stable, and our guide to how long everything in your house lasts walks through them in detail.

Now overlay a twelve year stay. If your water heater was new the day you closed, it will likely reach the end of its typical range before you leave. If the furnace was already eight years old at purchase, it too is probably yours to replace. Even a roof, the longest-lived of the big items, will land on your watch if you bought the house anywhere past its midpoint. A six year owner might dodge all three. A twelve year owner should expect to meet at least a couple of them personally.

Why does longer tenure change the money?

Two ways, and they pull in the same direction. First, the deferral trick stops working. A short-tenure owner who skips maintenance is, in effect, borrowing against a bill that will mature after they are gone. A twelve year owner who skips maintenance is still living there when the bill comes due, usually with interest in the form of secondary damage. There is no next owner arriving in time to absorb it.

Second, the payoff of doing things well finally accrues to you. Servicing the furnace, keeping gutters clear, and flushing the water heater have always extended system life. Over a short stay, most of that extension benefited a stranger. Over twelve years, you are the one who harvests the extra seasons. Longer tenure quietly turns maintenance from a courtesy to the next owner into compound interest you pay yourself. It also means the full carrying cost of the house is yours to plan for, a subject we take head-on in Buying the house was the easy part.

What should a twelve year owner do differently?

Four things, none of them dramatic.

• Learn the age of every major system now, not when something fails. Serial numbers, stickers on the unit, and the inspection report from your purchase will get you most of the way.
• Plan replacements as line items. If the water heater is in year nine of a typical 8 to 12 year life, its replacement belongs in your budget as an expected event, not a lightning strike.
• Maintain like you will be there when it matters, because you will. The filter changes and annual servicing you might once have rationally skipped now protect years you personally intend to live through.
• Keep records. Twelve years is far too long for memory. Who serviced the furnace in year two, what the roofer said in year four, which wall hid the plumbing repair: by year nine, none of that survives in anyone's head.

That last one deserves emphasis. Over a decade-plus, the house accumulates a real history, and the owner who wrote it down owns an asset the forgetful owner does not: proof for insurers, context for contractors, and a story for the eventual buyer. Holm exists for exactly this kind of long-haul ownership, and you can see how it fits your situation on our page for homeowners.

Is staying put bad news, then?

No. It is arguably the better deal, as long as you own it consciously. A family that stays twelve years gets to know its house the way you know an old car: which sounds are nothing and which are new, what was fixed and what was merely patched. That knowledge makes every repair decision cheaper and every emergency calmer. The trap is only in keeping a six year mindset, deferring and forgetting, while living on a twelve year clock.

The house is going to spend those years writing its story on your watch either way. The difference is whether anyone is taking notes. If you would like the taking of notes to be effortless, a quiet record that grows while you simply live there, Holm was built for the long stay.
