Davis County vs San Juan County.

Home values

The price gap here is the headline. The county median is ~$505,500 in Davis County against ~$224,200 in San Juan County, less than half, and San Juan carries the lowest median home value of any county in the state. Household income tells the other side: ~$110,900 in Davis against ~$64,500 in San Juan. A lower price in a county with a small job market and almost no private land is not the same as a bargain, and the reason San Juan homes cost what they do is not that houses are cheap to build there. It is that few people are bidding on them, and almost nobody is building new ones.

In Davis County the money runs from the south bench out to the west side. The established, higher-priced streets are the south bench cities closest to Salt Lake, Bountiful, Centerville, and Kaysville, nearly built out and trading on location. The newer, larger homes are out west toward Syracuse and Clearfield, and Layton is the biggest market in the middle of the range. The price pages show what a budget actually buys: Layton under $600K, Bountiful under $650K, and Kaysville under $700K.

In San Juan County the money pools in two towns along US-191. Monticello, the seat at the base of the Abajo Mountains, and Blanding, the larger town about half an hour south, hold most of the county's homes between them, and most of what trades in a year is an older house in one of those two grids. Inventory is thin because so little of the county is private land, and a listing can sit or sell depending on the month. Monticello under $500K covers nearly everything in the seat, and the Monticello and Blanding listings are worth a standing alert rather than a one-time look.

So the same budget buys two different lives. In Davis County it buys an older house on a small lot inside a crowded bench, with a job market, an airport, and a freeway around it. In San Juan County it buys a house with room around it in a town of a few thousand, hours from that bench, with the biggest scenery in the state out the back door. Neither is the bargain; they are answers to different questions. The cost-of-living guide lays the whole state out by region, and the affordability calculator turns either median into a number you can shop with.

Taxes, county by county

On taxes the two counties split in a way that surprises people. Utah taxes a primary residence on part of its value, and the certified rate works out to ~0.6% effective on a primary home in Davis and a bit higher at ~0.8% effective on a primary home in San Juan, where a small population spread over a huge area still has to pay for county services. On a San Juan median the bill is a fraction of what the Davis rate produces on its median, because the values are so far apart. Check the exact certified rate for any address with the county before you commit.

Sales tax runs the other direction, and neither is much of a lever. The combined rate at the register is ~7.25% in Farmington against ~6.65% in Monticello. In San Juan the lower rate is cold comfort, because the nearest full-line store is often out of the county, and what you save at the register you can spend and then some on the drive to reach one.

The trade behind the price

What the higher Davis price buys is position. Every Davis city is a short drive or a FrontRunner stop from Salt Lake and its airport, the household incomes are among the highest in the state, and the county is settled, with mature streets and an economy anchored by Hill Air Force Base. The bench is where the price lives: the east-side streets climb toward the Wasatch, and the closer a city sits to the Salt Lake line, the more it costs. What Davis does not buy is a new house at the edge of town, because Davis is nearly out of edges. New construction is mostly a west-side story now, and if a newer home is the priority, look at new construction in Layton and new construction in Syracuse.

What the lower San Juan price buys is space and scenery, and the price of that is distance. Only 8% private land here, one of the lowest shares in the state, so homes cluster in and around Monticello and Blanding and the open country stays open. That is the appeal: the Abajo Mountains behind Monticello, Cedar Mesa and Comb Ridge south of Blanding, and Bears Ears and the Needles out past the edge of town. The cost is that a specialist, a big-box store, or a commercial airport is an hour or more away, every time. Because so little ground is private, there is no subdivision machine at work either, so what is listed is usually older, and the patient buyer is the one who lands a home here. If a single-level home is the goal, single-story homes in Monticello is the filtered view.

Elevation and seasons

On weather these counties are not the same place at all, and the reason is elevation. Farmington sits at ~4,300 ft, valley bench below the Wasatch, with four seasons, a July high around ~91 °F, and January lows near ~20 °F. Monticello sits far higher, at ~7,070 ft, base of the Abajo Mountains, which makes it one of the coolest towns in the state in summer, around ~83 °F in July, and genuinely cold and snowy in winter, with January lows near ~14 °F.

That elevation gap matters more than the miles. In Davis, the bench climbs toward the Wasatch, and every hundred feet buys cooler summer nights and a little more snow on the driveway, which is part of why the bench streets cost more. In San Juan, elevation is the whole weather report: Monticello gets real mountain snow and a short growing season, Blanding about a thousand feet lower is milder and drier, and the canyon country around Bluff and Mexican Hat is high desert that bakes in summer. At Monticello's height the snow piles up and stays, which is a real factor in a county where the plow has a long way to go. A buyer moving from the coast or the low desert should plan for four real seasons in both counties.

Water, air, and the valley floor

The air is where they flip. Davis sits under the winter inversion, the lid of cold air that traps haze on the valley floor for days at a time in December and January, and its northwest corner fronts the Great Salt Lake, which has been near record lows and whose exposed bed is part of the county's air picture. San Juan trades that for clean, thin air at seven thousand feet, and some of the darkest night skies in the country; Natural Bridges was the first certified International Dark Sky Park. If clear air and a night sky matter to the move, the two counties could hardly be further apart.

Water tells the same story. Davis fronts the Great Salt Lake and has Antelope Island, a real state park reachable across the causeway, and its lakeside and marsh country are part of daily life. San Juan is dry country, and a rural home's water is often a well or a shared system you should ask about before you make an offer. The San Juan River runs along the southern edge, and small reservoirs like Recapture north of Blanding and Loyds Lake near Monticello hold local water, but this is country where you learn where the water is. In a county this large, the water question changes town by town, and it is one more reason to read the ground before you buy.

Public land and the map

Here is the biggest physical difference, and it hides in one row of the table. Davis is 25% private land and 11% federal, which sounds like mountain-county scarcity but is not: the Great Salt Lake and Antelope Island, both state and sovereign land and water, fill a large share of the county's area, so most of the rest is buildable bench. The outdoor life that comes with it is the island, the flat Legacy Parkway Trail, the canyon trailheads at the top of the bench, and Farmington Bay for the birds. The catch is that Davis has no ski hill and no real backcountry of its own; the mountains are a drive, not a back fence.

San Juan is the opposite map, and it is the whole story of the county. Only 8% private land here; 61% federal, and most of the rest is tribal and state trust land. That is why the towns are small islands in a sea of public ground, and why the scenery is the biggest in the state: the Needles district of Canyonlands and Indian Creek out UT-211, Natural Bridges and Cedar Mesa on the UT-95 and UT-261 country, the Abajo Mountains above Monticello, and Bears Ears National Monument wrapped around all of it. The flip side is that you cannot buy most of this county, and the private lots that do exist are worth understanding before you commit.

School districts

Each county runs a single school district, but the two could not be more different in scale. Davis runs Davis School District, one system covering all fifteen cities on a crowded bench. San Juan runs San Juan School District, a single district serving students across the largest county in the state, from Monticello and Blanding down to the San Juan River towns, so distance and busing are real facts of school life. I do not rate schools here or anywhere on the site. I name the district, link the city guide, and leave the judgment to you and the district's own published data: Layton, Farmington, Monticello, and Blanding.

Colleges and universities

Higher education splits the way the map does. Davis has Weber State University Davis Campus (Layton), Davis Technical College (Kaysville), with the main campus of Weber State just a few exits north in Ogden, so a full university town is a short drive rather than a move. San Juan has Utah State University Blanding, and in a county this remote that campus matters more than the enrollment numbers suggest, because it keeps a college presence in Blanding instead of sending every student to the Wasatch Front.

Hospitals and the airport

Health care splits hard. Davis has full hospital care close everywhere in the county: Lakeview Hospital (Bountiful), Intermountain Layton Hospital, Holy Cross Hospital Davis (Layton). San Juan has two small hospitals, San Juan Hospital, Monticello; Blue Mountain Hospital, Blanding, which handle routine and emergency care, but a serious or specialized case usually means a long drive north or a flight. That distance is the single most important thing to weigh honestly before a move to a county this remote.

The airport is the cleanest illustration of the whole comparison. Davis has none of its own, but Salt Lake City International is ~25 min from Farmington, a Delta hub with direct flights most places. San Juan has no airport with scheduled service at all. The nearest commercial flights are out of Cortez, Colorado, about an hour from Monticello, or a little further at Canyonlands Field near Moab, and reaching Salt Lake's airport is most of a day's round trip. For a frequent flyer, that alone can decide the question.
