Downsizing Math: What a Smaller Snohomish County Home Really Saves You

When homeowners first tell me they are thinking about downsizing, the conversation usually starts with the mortgage: what would the payment be on a smaller place? That is the wrong first question. The most expensive thing about a house that is bigger than your life is not the mortgage. It is everything you pay every month to own, insure, heat, cool, and maintain space you are not using. In Snohomish County right now, those quiet costs can add up to five thousand dollars a year or more, and they are the clearest financial argument for a home that fits how you actually live.

I am going to show you that math with current numbers, and I am going to keep it honest. The property tax figure comes from the county assessor's own rate, the utility figures come from Puget Sound Energy's published rates, and the maintenance figure is a widely used planning rule, not a promise. Your actual savings depend on your home, your next home, and your habits. But the direction is clear: a smaller home in Snohomish County is genuinely cheaper to carry, by thousands of dollars a year, and that is before the mortgage enters the picture.

The size gap in today's Snohomish County market

According to the Northwest Multiple Listing Service's September 2026 market snapshot, the median single-family home in Snohomish County sold for about $745,000, while the median condo was $466,500. A gap of close to $280,000. I start there because it frames the whole decision: a household that sells a typical family home in this market is often holding enough equity to buy the smaller place outright, or close to it, and then the annual savings below are pure gain instead of a trade-off.

Property taxes: the county assessor's own numbers

Snohomish County collects property tax at a rate that varies by levy code, but the assessor's 2025 typical rate is $8.2769 per $1,000 of assessed value. Run that against two realistic prices and the difference is plain:

• A home assessed at $750,000 pays roughly $6,210 a year in property tax.
• A home assessed at $500,000 pays roughly $4,140 a year.

That is about $2,070 a year, or $170 a month, from this line alone. Every city, school district, and fire district has its own rate, so your exact bill moves with your street address, but the gap between a typical family home and a typical smaller home is real, and it repeats every single year you own the place.

Heat and power: you pay for every square foot

Size shows up on the utility bill whether you are in the room or not. A typical single-family home served by Puget Sound Energy runs about $122 to $138 a month for electricity and about $88 to $90 a month for natural gas at current rates, roughly $210 to $225 combined. That is a countywide average, and the biggest single driver of the spread between households is square footage.

Heating cost models put the difference in plain terms: a 2,500-square-foot home heats for around $1,036 a year on natural gas, while a home under 1,500 square feet heats for around $622. That is more than $400 a year on heat alone, before you add lighting, water heating, and cooling for the extra thousand feet. Your actual number depends on your furnace, your thermostat, and how drafty that hallway is, but a smaller footprint costs less to keep comfortable every month of the year.

Maintenance: the 1% rule

Lenders and consumer finance sources commonly suggest budgeting around 1% of a home's value each year for maintenance and repairs. At that widely used baseline:

• A $750,000 home: about $7,500 a year, or $625 a month, set aside for upkeep.
• A $500,000 home: about $5,000 a year, or $417 a month.

Now let me add the perspective from my former life. I spent ten years as a master electrician in residential and commercial construction before I sold real estate, and the pattern is consistent: bigger houses have more roof, more siding, more windows, more HVAC, more of everything that eventually needs attention. For a well-lived-in family home, I treat the 1% rule as closer to a floor than a ceiling.

Insurance: more house, more premium

I am not going to put a made-up number in front of you, so I will say it straight: homeowners insurance follows replacement cost, and a house with more square footage costs more to rebuild. Premiums in Washington have climbed in recent years, and the policy on a larger structure carries a larger premium. Get quotes on your actual next home before you budget, because this line moves with the size of the house and it is entirely real.

What it adds up to

Put the three sourced numbers together, comparing a typical family home in the $750,000 range with a typical smaller home in the $500,000 range:

• Property taxes: about $2,070 a year less.
• Utilities: roughly $400 to $1,000 a year less, depending on heat source and habits.
• Maintenance at the 1% rule: about $2,500 a year less.
• Insurance: less, because the replacement cost is lower.

That is $5,000 to $5,500 a year, somewhere around $420 to $460 a month, before you finance a cent of the next purchase. If that money is going out the door today to keep empty rooms warm and insured, it does not disappear when you move. It stays in your pocket.

The mortgage side of the ledger

That analysis assumes you are comparing the same money side: your own. The mortgage is the other column, and it is personal. If you sell with strong equity and roll the proceeds into a smaller place, you may borrow very little at today's rates, which is the strongest argument downsizers have right now. If you instead buy a newer, more expensive smaller home, or if giving up a low-rate mortgage matters to you, the monthly payment can move the other way. I wrote the full comparison of whether giving up a low rate is worth it and the guide to how much equity a move-up really takes, because those two questions come up on almost every downsizing call.

The one caution I repeat on every downsizing call

A smaller home is not automatically cheaper. A condo with a hefty HOA payment can eat the tax savings and then some, and a newer small home in a higher-priced city can cost more to carry than an older big one. The comparison that matters is your address today against the actual homes you would buy, using their real taxes, their real insurance quotes, their real HOA dues, and their real utility history. Averages describe the county. They do not describe your street.

Knowledge creates confidence. When you can see the annual cost of staying and the annual cost of moving side by side, with your own numbers, the decision stops being emotional and starts being arithmetic.
