Here is the honest posture on Star: it is not a budget option. Sitting in Ada County along the Boise River corridor about 25 minutes northwest of downtown Boise, Star has grown from a rural crossroads into one of the Treasure Valley's faster-developing suburbs — and prices have followed. The cost-of-living index for Star sits at 115 against a national baseline of 100, which means nearly every line item, from housing to utilities, runs somewhat above what you would find in an average American city. What draws people here despite that number is a combination of newer construction, more land per dollar than you would find closer to Boise proper, and a small-town character that larger suburbs can no longer credibly claim.
The economic backbone of Star is largely tied to the broader Treasure Valley economy. Ada County Highway District, local healthcare providers, and a construction industry still building out the city's newer neighborhoods round out the local job base. Most households with professional-level incomes commute to Boise, Eagle, or Meridian for work, which makes driving time a daily cost worth factoring into any household budget. The median household income in Star is $97,936, which is meaningfully above the Idaho state median and reflects the working professional and dual-income households that make up much of the city's population.
Against that income backdrop, housing is the number that dominates every budget conversation. Electricity from Idaho Power runs noticeably below the national average, gas prices are modest by western standards, and Idaho's tax structure is genuinely competitive — but none of that offsets a typical home price that has crossed the half-million mark. The upside compared to neighboring Eagle, or to Boise neighborhoods closer to downtown, is real. The downside compared to Caldwell or Nampa is equally real. Where you land depends almost entirely on whether Star's particular mix of space, newness, and access justifies its premium over the valley's more affordable western options.
The sections below break down Star's housing market, everyday non-housing costs, a sample monthly budget, a side-by-side comparison with nearby cities, and the Idaho tax picture — everything you need to stress-test your budget before making an offer or signing a lease.
What It Really Costs to Live in Star
Star's typical home price is $560,399 (Zillow Home Value Index, May 2026). That figure puts Star above the Idaho statewide median and above what buyers find in Caldwell or Nampa, while remaining noticeably below Eagle and the pricier stretches of Boise. That spread is the defining financial reality of choosing Star.
What drives the number here is a combination of geography and timing. Star's buildout accelerated sharply during the post-2020 Treasure Valley surge, and most of the housing stock is relatively new single-family construction on larger lots. New builds carry a price premium, and Star has a disproportionate share of them. Buyers who do not need the newest finishes can find older homes that undercut the typical figure, but the market's center of gravity sits firmly at that half-million-plus level.
The overall cost index of 115 is driven almost entirely by housing. Non-housing costs — utilities, groceries, transportation — are all close to or only modestly above the national average. If you are relocating from a high-cost coastal market, Star will feel like relief. If you are comparing it to Nampa or Caldwell, the premium is harder to ignore, and the honest question is whether Star's proximity to Boise and its newer infrastructure justifies the gap.
Housing: Rent vs Buy in Star
Buying
Entry-level ownership in Star typically starts in the low-to-mid $400,000s for older construction or smaller footprints, with the market median pulling toward the upper $500,000s on newer builds. For a ground-level look at how prices vary across specific parts of the city, the Best Neighborhoods in Star guide maps out where the price tiers actually fall.
The effective property tax rate in Ada County is approximately 0.76% of assessed home value for the 2025–2026 assessment year — well below the national median of around 1.02%. Owner-occupants who qualify for the Idaho Homestead Exemption get an additional break: 50% of the home's assessed value, up to $125,000, is shielded from taxation. For a household buying near the city median, that exemption makes a material difference in the annual tax bill. Use the mortgage calculator below this section to model your specific payment — monthly housing costs vary too much by down payment and loan structure to generalize usefully here.
Renting
The rental market in Star is thinner than in Meridian or Nampa — this is predominantly a homeownership city, and the apartment inventory reflects that. Two-bedroom rentals generally run in the $1,400–$1,800 per month range, with newer or larger units pushing higher. Single-family rental homes, which are more common here than apartments, often command $1,800–$2,200 or more depending on size and build year.
Renting makes sense in Star if you are new to the Treasure Valley and want twelve months to learn which part of the city fits your life before committing to a purchase. It is not a long-term money-winner here: with rents as high as they are and ownership at a relatively modest property-tax rate, buyers who can manage a down payment and plan to stay at least three to four years typically come out ahead on the math.
Everyday Costs Beyond Housing in Star
Idaho Power serves Star and the broader Treasure Valley, and its residential electricity rates average approximately 12.35 cents per kWh — roughly 35% below the national average. The catch is summer: June through September tiered pricing kicks in to reflect peak cooling demand, and a Star household running central air through an August heat event will see a bill meaningfully higher than the off-season baseline. Gas prices in Idaho have historically run below the national average, with regular unleaded hovering in the $3.51–$3.61 per gallon range through 2025, which keeps the drive into Boise or Meridian from being a budget-breaker. Groceries in Idaho track close to the national average — the Bureau of Economic Analysis pegs per-person non-restaurant food spending at roughly $319 per month — though Idaho does levy its 6% sales tax on groceries, partially offset by the state's Food Tax Credit of $155 per person for tax year 2025.
Healthcare costs in Star itself are limited by the city's size — most residents drive to Eagle, Meridian, or Boise for specialist care — but Idaho's overall healthcare cost index runs close to the national average, and residents with employer-sponsored coverage from a Boise or Meridian employer are not at a structural disadvantage. Phone and internet options include the major national carriers and cable-based broadband; pricing is standard for a suburban Idaho market.
| Category | Typical Monthly Cost | Notes |
|---|---|---|
| Housing (2BR Rent) | $1,400–$1,800 | Owners: use the mortgage calculator above for a payment estimate based on your down payment and rate |
| Utilities (Electric, Gas, Water) | $140–$200 | Electric via Idaho Power; higher June–September due to A/C demand |
| Groceries | $600–$850 | For 2 adults; Idaho charges 6% sales tax on groceries, partially offset by the state Food Tax Credit |
| Transportation & Gas | $250–$400 | Assumes 1–2 vehicle household; gas ~$3.51–$3.61/gal; no meaningful public transit option from Star |
| Healthcare | $150–$350 | Estimate for employer-plan cost-sharing; most specialist care requires a drive to Meridian or Boise |
| Phone & Internet | $100–$180 | Standard suburban Idaho market pricing; cable-based broadband widely available |
| Misc / Discretionary | $300–$600 | Dining out, recreation, household supplies; Star has limited local dining — expect trips to Eagle or Meridian |
These are estimates for planning purposes, not guarantees. A single-person household will land toward the lower end of most ranges; a family of four should budget toward the upper end, particularly on groceries and transportation.

Eagle commands a clear premium over Star — its established west-side cachet and proximity to the Boise foothills have consistently pushed prices higher. Meridian, despite being far larger and more urban, trades at roughly the same price point as Star, which surprises many buyers; the difference is what you get for the money — newer, larger lots in Star versus denser, more accessible retail and services in Meridian. Nampa and Caldwell are where buyers priced out of Star tend to land, accepting a longer drive to Boise in exchange for substantially lower entry costs.
Taxes & the Bottom Line for Star
Income Tax
Idaho moved to a flat 5.3% individual income tax rate effective January 1, 2025 — down from the prior 5.695% following Governor Brad Little's signing of HB 40 in March 2025. For a household earning near Star's median of $97,936, that flat rate is a genuine advantage over progressive-rate states where the same income would face a marginal rate of 8–13%. Idaho ranks 9th overall on the Tax Foundation's 2026 State Tax Competitiveness Index, reflecting that the income-tax structure is a net positive for most working households.
Sales Tax
Idaho's statewide sales tax is 6%, with no local add-ons in most Treasure Valley jurisdictions, bringing the effective combined rate to approximately 6.03%. The one friction point is that Idaho taxes groceries at the full 6% rate. The state partially offsets this through the Food Tax Credit — $155 per person for tax year 2025, claimable on the annual state return — but families with four or more members will spend more at the register than the credit fully covers.
Property Tax
At approximately 0.76% effective rate in Ada County, property taxes are well below the national median. Owner-occupants who file for the Homestead Exemption — which shelters 50% of assessed value up to $125,000 — reduce that burden further. Ada County's consolidated tax bill covers roughly 40 different taxing districts, so the specific rate on any parcel depends on which districts overlay it; checking the Ada County Assessor's parcel data before closing is worth the ten minutes.
Who Star's Budget Fits
The math works most comfortably for dual-income households earning $90,000 or more combined, buyers who can bring a meaningful down payment, and people relocating from higher-cost western markets where the home-price figure here looks like a discount rather than a stretch. It tends to be a tighter fit for single-income households at or below the state median, buyers who need to carry a vehicle payment on top of housing, and anyone expecting to find the same cost profile as Nampa or Caldwell. The tax structure helps — Idaho's flat rate and low property taxes are real money back in the budget — but they do not change the fundamental reality that home prices are the biggest variable in any Star budget conversation.
Local Expert Takeaway: Star's cost story is really a housing story. Idaho Power's electricity rates run well below the national average, gas is cheap, and the flat 5.3% income tax beats most western states — but none of that moves the needle if the home price doesn't work for your down payment and income. The buyers who find Star genuinely good value are those comparing it to Eagle or central Boise, not those comparing it to Nampa. If you are on the fence, spend an afternoon along W State Street, take stock of the space and the newer infrastructure around you, and ask yourself whether that 25-minute Boise run feels worth the premium over the valley's western cities — because that is the real decision.
