Everyone shows you the houses. Almost nobody shows you the numbers behind them.

Why the Treasure Valley, and Why Now?

The Treasure Valley sits in southwestern Idaho, anchored by Boise and spanning Ada and Canyon counties. With a metro population of roughly 800,000, it has been one of the fastest-growing regions in the country for years. As Connor puts it, prices in several of these cities are still accessible. Not cheap, but accessible. For buyers relocating from Portland, Seattle or the Bay Area, the math often comes as a pleasant surprise.

Canyon County Entry Points: Caldwell and Nampa

Caldwell, Idaho: About $384,000

Caldwell is the valley's entry point. At a median of about $384,000, the principal and interest payment is roughly $2,130 a month, or around $2,500–$2,600 with taxes and insurance. A household income of about $72,000–$78,000 is a comfortable qualifying range. Caldwell is a working town with a growing downtown and some of the most affordable housing in the Boise metro, which makes it a strong fit for first-time buyers who want their dollar to stretch.

Nampa, Idaho: About $390,000

Right next door, Nampa is Canyon County's largest city, with a median near $390,000 and a payment around $2,160. Qualifying income is similar to Caldwell's at roughly $73,000–$79,000. Nampa has changed a lot in the last five years: its downtown now has restaurants, breweries and a farmers market, and you're still well below Ada County pricing.

The Value Plays: Kuna and Middleton

Kuna, Idaho: The Most Affordable City in Ada County

Kuna is where you cross into Ada County. The median is about $440,000, with a payment near $2,440 and qualifying income of roughly $82,000–$90,000. Kuna prices are up 8.4% year over year. This family-oriented town south of Meridian is currently the most affordable city in Ada County. If you want Ada County schools and services without peak Ada County prices, Kuna is worth a close look.

Middleton, Idaho: Watch the Highway 16 Corridor

Middleton surprises a lot of buyers. The median is about $450,000, with a payment near $2,490 and qualifying income around $84,000–$92,000. The reason to watch it is Highway 16, which is expected to open in early 2027 and create a direct corridor from Middleton to I-84 and the Boise metro. Shorter commutes have historically pushed home values up, so buyers who like to get in before the infrastructure catches up should give Middleton a serious look.

The Established Centers: Boise and Meridian

Boise, Idaho: A Huge Range by Neighborhood

Boise's price range is enormous. You can find a condo near Boise State for around $460,000 (about $2,550 a month, with roughly $86,000–$96,000 in income needed), or a home in the North End or East Boise for $780,000 or more. At $700,000 and up, expect payments of about $3,880+ and qualifying income above $130,000. Boise is the economic center of the valley, with the jobs, the airport, the restaurants and the culture, and you pay for that. If you work in Boise but don't need to live there, the surrounding cities often make more financial sense.

Meridian, Idaho: The Valley's Biggest Suburb

Meridian's median is about $566,000, with a payment near $3,130 and qualifying income around $102,000–$115,000. It has arguably the best infrastructure in the valley: The Village at Meridian, newer developments, strong schools and plenty of parks. It's where many families relocating from out of state land, because it feels like the most "finished" suburb. You pay a premium for that polish, but you get a lot of city for the money.

The Growth Bet: Star, Idaho

Star is the city to pay attention to. The median is about $610,000, the payment is roughly $3,380, and qualifying income runs about $110,000–$120,000. The headline number is 14.8% year-over-year appreciation, the fastest in the Treasure Valley. Star is where new construction is concentrated, it sits right on the Highway 16 corridor, and it's attracting the buyers who would have chosen Eagle five years ago.

"If appreciation holds anywhere close to that pace, a $610,000 home today could be worth $700,000 in 18 months." – Connor Webb, Envoy Mortgage

Past appreciation is not a guarantee of future performance, but Star's momentum is hard to ignore.

Top of the Market: Eagle, Idaho

Eagle is the valley's premium market, with a median near $789,000. The payment is about $4,370 a month, and qualifying income runs roughly $140,000–$160,000 depending on your debt profile. Expect large lots, custom homes, foothill views and nearby wineries. For buyers coming from places like Lake Oswego, Oregon or Mercer Island, Washington, Eagle offers a similar lifestyle at a lower price point. For many buyers, though, Connor suggests starting in Star and letting appreciation help you move up.
