Salt Lake County vs San Juan County.

Home values

The gap here is not subtle. The county median is ~$525,700 in Salt Lake County and ~$224,200 in San Juan County, so a dollar goes more than twice as far down in the red rock. Household income tells the other half of the story: ~$97,500 in Salt Lake against ~$64,500 in San Juan. A lower price in a county with fewer jobs 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 out there. It is that so few people are bidding on them, and that almost nobody is building new ones.

In Salt Lake County the money runs east to west. The bench under the Wasatch, from Cottonwood Heights down through Sandy to Draper, carries the highest values in the valley, and the west side, West Valley City, Kearns, and much of West Jordan, carries the lowest. A buyer who wants to stay under half a million shops west of I-15 or north of downtown, and the price pages show what that looks like street by street, from West Jordan under $500K to Salt Lake City under $500K. Even the low end of Salt Lake County sits well above the high end of San Juan.

In San Juan County the money runs along one highway and pools in two towns. Monticello, the county 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 given year is an older house in one of those two grids. Everything else is scattered: a place in Bluff along the San Juan River, a lot near Mexican Hat, a parcel at the edge of the reservation. There is almost no new construction, because there is almost no private land to build on. When a listing does come up in Monticello or Blanding, it tends to sell to someone who already knows the county.

So the same budget buys two different lives. In Salt Lake County it buys an older house on a small lot inside a metro of more than a million people, with a job market, a hospital, and an airport around it. In San Juan County it buys a house with room around it in a town of a few thousand, hours from that metro, with the biggest scenery in the state out the back door and a long drive to a full grocery run. 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 county's median into a monthly number you can shop with.

Taxes, county by county

Property tax is a touch higher in the small county, though the bill behind it is far smaller because the home values are. Utah taxes a primary residence on 55 percent of its market value, and the certified rate works out to ~0.6% effective on a primary home in Salt Lake City and ~0.8% effective on a primary home in Monticello. On a Salt Lake County median that is a real annual number; on a San Juan County median the same rate is a fraction of it. Check the exact figure for any address on the county assessor's site before you commit, because a school bond or a special service area for fire moves it more than the county line does.

Sales tax runs the other way. The combined rate at the register is ~8.45% in Salt Lake City against ~6.65% in Monticello, because the capital stacks city, transit, and venue levies on top of the state and county base that a rural county never adds. In San Juan the lower rate is cold comfort, though: 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 you are really buying in Salt Lake County is proximity. The airport is inside the county, ten minutes from downtown. Three TRAX lines and FrontRunner mean a household can get by on one car in a way that is impossible almost anywhere else in the state. And the region's biggest employers, Intermountain Health, the University of Utah, the state, and Delta, are all inside the county, so work, care, and a flight out are all close. You pay for that access in the price of the house and the size of the lot.

What you are buying in San Juan County is space and quiet, at the cost of distance from everything a metro takes for granted. The county covers ~7,820 sq mi of ground, more than ten times Salt Lake County's ~742 sq mi, and it is the largest county in Utah by area and one of the emptiest. That buys a backyard that runs to Cedar Mesa and the Needles, and it costs you a hospital with a specialist, a store with everything on the shelf, and a short drive to a plane. If a remote county is the point rather than the price, read the rural living guide before you fall for a view; it walks through the wells, the septic, the winters, and the distances honestly.

Elevation and seasons

Salt Lake City sits at ~4,300 ft, valley floor and runs a normal four-season valley climate: a July high around ~93 °F, January lows in the low twenties, and valley snow that comes and goes while the mountains above hold it for months. The bench, Sandy and Draper and the east side, sits a few hundred feet higher and a few degrees cooler, and buyers who care about a hot night shop by elevation before they shop by city.

Monticello sits much higher, at ~7,070 ft, base of the Abajo Mountains, and that changes everything about the weather. Summers are cool for Utah, a July high around ~83 °F, and winters are genuinely cold and snowy, with January lows near ~14 °F. Blanding, a thousand feet lower, is a little milder, and the canyon country to the west and south, Bluff, Mexican Hat, and the Lake Powell edge, is a different climate again, high desert that bakes in summer. In a county this size, elevation is the weather report.

Water, air, and the valley floor

Both the strength and the weakness of the Salt Lake air are on the valley floor. The winter inversion, the lid of cold air that traps haze over the valley for days at a stretch in December and January, is the county's real weather problem, and the bench sits above it more often than not, which is a second reason the bench costs more. The county's northwest corner touches the Great Salt Lake, which has been shrinking for years and whose exposed lakebed is now part of the air-quality picture; The Local's read on the Great Salt Lake explains why the valley watches the water level, and the valley in winter covers the lid itself.

San Juan trades that for clean air and scarce water. There is no metro haze at seven thousand feet, and the night skies over Cedar Mesa are some of the darkest in the country; Natural Bridges was the world's first certified International Dark Sky Park. What San Juan does not have much of is water. The San Juan River runs along the southern edge past Bluff and Mexican Hat, and Recapture Reservoir north of Blanding and Loyds Lake near Monticello are small local waters, but this is dry country, and a rural home's water is a well or a shared system you should ask about before you make an offer. The Local's Cedar Mesa page is the honest read on the ground west of town.

Public land and the map

The public land that matters most in Salt Lake County is small in share but huge in use. The county is 73% private land and 21% federal, and that federal slice is concentrated in the Wasatch canyons on the east side. Big and Little Cottonwood hold four ski areas, Alta, Snowbird, Brighton, and Solitude, and the most heavily used trailheads in the state, twenty minutes from the bench. The west side, the Oquirrh Mountains, is mostly private mining ground, which is why the Oquirrh side feels so different from the Wasatch side.

San Juan is the opposite kind of 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; basing a canyon life out of Blanding is the ground-level version.

School districts

Salt Lake County runs five districts: Salt Lake City, Granite, Jordan, Canyons, Murray. The lines follow the cities closely, and the two biggest, Granite across the center of the valley and Jordan across the southwest, each serve more than a dozen cities. San Juan County runs one: San Juan School District, a single district covering an area larger than several states, with schools in Monticello, Blanding, and the smaller communities including Bluff, Montezuma Creek, and Monument Valley. I do not rate schools anywhere on this site. I name the district, link the city guide, and leave the judgment to you and the district's own published data.

Colleges and universities

On higher education the gap is what you would expect. Salt Lake County has the University of Utah, the state's flagship and its largest research hospital, plus Salt Lake Community College across the valley and Westminster University on the east bench. San Juan County has Utah State University Blanding, a regional campus in Blanding that grew out of the old college there and now offers two-year and some four-year programs close to home, which in a county this remote is no small thing.

Hospitals and the airport

Salt Lake County holds the medical center of the whole Intermountain West: Intermountain Medical Center, University of Utah Hospital, Primary Children's, St. Mark's, LDS Hospital, Riverton, Alta View, Jordan Valley, Lone Peak, among others. If a specialist matters to your move, there is a real chance that specialist practices in Salt Lake County no matter where in the state you live. San Juan County 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 flight or a long drive north. 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. Salt Lake City International sits inside Salt Lake County, ten minutes from downtown, a Delta hub with direct flights most places. San Juan County has no airport with scheduled service. The nearest commercial flights are out of Cortez, Colorado, about an hour from Monticello, or a little further at Moab's Canyonlands Field, and reaching Salt Lake's airport is most of a day's round trip. For a frequent flyer, that alone can decide the question.
