You did the math. A $550,000 home in Saratoga Springs versus your $1.2 million house in the Bay Area or Orange County. The mortgage payment alone feels like a gift. You start mentally furnishing the basement and pricing out ski passes.
I get it. When I made my own move, that number gap felt like oxygen after years of financial suffocation. But here is what I wish someone had told me before I got too attached to a Zillow listing: the sticker price is only the beginning of the math. And California buyers, specifically, are wired to miss the second half of the equation.
Let me walk you through where the surprises tend to hide.
Your California Property Tax Brain Is Going to Mislead You
California’s Prop 13 is one of the most buyer-friendly tax laws in the country. Once you buy, your assessed value is essentially locked, and your annual increases are capped at 2%. Many long-term California homeowners are paying property taxes based on values from a decade ago.
Utah does not work that way.
Homeowner’s Insurance Is Not What It Was Three Years Ago
Utah’s property tax rate is generally lower on paper, hovering around 0.5 to 0.6 percent in most Utah County areas. That sounds great until you realize the county reassesses at closer to current market value. On a $550,000 home, you are looking at roughly $2,750 to $3,300 per year in property taxes, which is manageable. But if you have been paying Prop 13-adjusted taxes on a home that appreciated to $1.2 million, your California tax bill may actually have been surprisingly low. Do not assume Utah feels cheaper just because the rate looks smaller.
This one is quietly wrecking affordability for buyers across the country right now, and Utah County is not immune. A thread on r/realestate recently sparked a real conversation about how insurance, taxes, and HOA fees are reshaping what people can actually afford month to month, even in markets that look affordable on the surface.
Utah is not California when it comes to wildfire risk in most valley locations, which helps. But wind, hail, and flooding from spring runoff are real considerations depending on where you buy. Homes in newer subdivisions near the foothills or in areas with limited hydrant access can carry higher premiums than buyers expect.
Budget $150 to $250 per month for homeowners insurance as a starting point, and get quotes before you close, not after. I tell every client to treat insurance shopping like a part of the inspection process. It is that important.
HOA Fees: Read the Fine Print Before You Fall in Love
A big chunk of Utah County’s inventory, especially in master-planned communities like Saratoga Springs, Eagle Mountain, and parts of Lehi and South Jordan, comes with an HOA. Sometimes two.
HOA fees in these communities typically run $50 to $150 per month, but that is not the number that surprises people. What surprises them is what is not covered. Many Utah County HOAs handle common area landscaping and community amenities, but they do not cover your roof, exterior paint, or driveway. If you are coming from a California condo or townhome HOA that covered exterior maintenance, the mental accounting can throw you off.
Also worth knowing: some communities have additional special assessment zones for infrastructure. Ask your agent to pull the full HOA financials and reserve fund before you make an offer. I do this for every client as a standard step, not an afterthought.
Radon: The Utah County Cost Nobody Budgets For
This one surprises nearly every California buyer I work with, because it is simply not on most people’s radar when they move from the coast.
Utah County sits on geology that produces elevated radon levels in many areas, particularly in the southern and western parts of the valley. The University of Utah Health system has flagged this as a legitimate public health consideration for homeowners in the region. Radon is a colorless, odorless gas that seeps up through the ground and can accumulate in lower levels of homes.
The good news: radon mitigation systems work, and they are not outrageously expensive. A typical installation runs $800 to $1,500. But if you are buying a home that needs one and it is not already installed, that is a cost to negotiate or plan for. And if you are building new in south Utah County, ask the builder directly whether radon-resistant construction is included. Some include it standard, some do not.
So What Does the Real Number Look Like?
Here is the honest version of the monthly budget for a $550,000 Utah County home:
Principal and interest on a 30-year mortgage at current rates: roughly $3,100 to $3,300 depending on your rate and down payment. Property taxes: $230 to $275 per month. Homeowners insurance: $150 to $225 per month. HOA (if applicable): $75 to $150 per month.
Before you add utilities, internet, or radon mitigation, you are already looking at a real monthly cost that could be $500 to $800 higher than the mortgage payment alone.
That is still often significantly less than what California buyers are leaving behind. But it is a very different number than what the listing calculator shows you.
Do the Full Math Before You Pack the Truck
The Utah County market is not giving buyers a rescue right now. As of 2026, housing analysts are describing it as essentially running in place, with prices holding steady rather than dropping. What you see is largely what you will pay.
That is actually fine, because this market still makes sense for a lot of California families. It just makes sense when you go in with the real numbers in front of you, not the headline number.
If you want to run the actual monthly cost breakdown on a specific home you are considering, reach out. I do this for every buyer I work with, and it takes about twenty minutes. It is one of the most useful conversations you can have before you get emotionally attached to a floor plan.
