Homes for Sale in Ada County, Idaho

Not across Ada County broadly, though the picture varies meaningfully by city - Boise and Star have posted gains, while Meridian's recent data leans slightly down.

• Ada County overall: median sale price $567,900 as of June 2026 (Intermountain MLS), with the county's home prices up roughly 300% from the 2011 trough.
• Boise: median sale price figures range $495,000-$535,000 depending on window, with modest gains in most recent snapshots.
• Meridian: median sale price $550,000, down 2.1% year over year in a recent three-month window - the one city in the county showing a clear recent decline.

See Boise's, Meridian's, Eagle's, Star's or Kuna's own pages for city-specific detail.

Each of the county's five cities in this build serves a different priority - there is no single "best," only a best fit for a specific buyer.

• Boise: the largest job market and most urban amenities.
• Meridian: newer housing stock and rapid retail growth, at a price point currently above Boise's own average.
• Eagle: the county's most expensive, most semi-rural option, with larger lots and river access.
• Star: the fastest-growing of the five, with lower entry prices than Eagle but rapid ongoing transformation.
• Kuna: a family-oriented, high-income-relative-to-price option in the county's south.

Within Ada County, Kuna and Boise run below Meridian, Star and Eagle on median price - though none of the five is among Idaho's statewide cheapest towns by most rankings, which instead point to towns like Weiser, Payette or Rupert, all outside this county.

• Kuna: $423,900 median home value, the county's most affordable of the five cities in this build.
• Boise: $508,258-$535,000 depending on measure.
• Eagle: $799,000-$963,495 depending on measure - the county's most expensive by a wide margin.

Ada County's countywide median sale price was $567,900 as of June 2026, though that figure blends a wide internal range from Kuna's roughly $424,000 to Eagle's near-$800,000-plus.

• Ada County: $567,900 median sale price (Intermountain MLS, Jun 2026); a separate Zillow average value figure shows $530,009.
• The county's median home value has risen from $122,400 in 2000 to an estimated $541,300 in 2024 - more than a fourfold increase.
• Any single "Ada County" figure obscures more than it reveals given the roughly $375,000 spread between the county's cheapest and most expensive cities in this build.

Idaho is the cheaper state overall by cost-of-living index, though Ada County's own home prices - particularly Eagle's and Meridian's - run above Oregon's statewide median, making the state-level tax comparison less decisive here than in this build's smaller core-market towns.

• Idaho: flat 5.3% income tax, 6% sales tax including groceries (Idaho State Tax Commission, 2026).
• Oregon: graduated income tax up to 9.9%, no sales tax at all (Oregon DOR, 2026).
• Ada County's $567,900 median sale price runs above Oregon's statewide typical home value of roughly $499,000-$511,000 - a reminder that "Idaho is cheaper" doesn't hold true city-by-city inside the state's most expensive county.

Across the Boise metro, including Ada County's five cities, midwinter is typically the slowest stretch for buyer traffic, with spring and early summer bringing the most activity.

• Fast-growing cities like Star and Kuna see new listings enter the market year-round as construction continues, which can partly offset the usual winter slowdown compared to a more static market.
• Eagle's luxury-skewed inventory tends to move more slowly regardless of season, given its smaller buyer pool at that price point.
• A correctly priced home still sells faster than an overpriced one in any month - timing matters less than pricing.

Deferred maintenance, outdated systems (roof, HVAC, electrical) and overpricing relative to the immediate competition are the most consistent value-reducers in a market as competitive as Ada County's.

• In a fast-moving market, homes needing visible repairs sit longer and typically sell for less relative to list price than move-in-ready comparables.
• Over-improving for the neighborhood - a renovation priced well above what surrounding homes support - rarely returns its full cost at resale.
• In Ada County's newer-construction cities (Meridian, Star), a dated interior can stand out more sharply against neighboring new-build inventory than it would in an older, more architecturally consistent area.

Using standard lending assumptions (28% debt-to-income, 20% down, current mortgage rates), a $400,000 home in Ada County requires roughly $99,000-$100,000 in annual household income - though this is an extrapolation from statewide formulas, not a figure calculated specifically for this price point.

• Statewide, Idaho households need roughly $125,161 to afford the median $503,400 home under the same standard assumptions - the median Idaho household falls about $50,525 short of that figure.
• A $400,000 home is below Ada County's own $567,900 median sale price, meaning it would most likely be found in Kuna or entry-level Boise inventory rather than Meridian, Star or Eagle at current prices.
• Actual qualification depends on debt load, down payment, credit and current rates - a lender's pre-approval, not a general formula, is the reliable answer for a specific buyer.

In a competitive market like Ada County's, the most common seller mistakes are overpricing based on a neighbor's sale rather than current comparables, over-personalizing a major renovation, and skipping pre-listing repairs that a buyer's inspection will surface anyway.

• Pricing above what recent, comparable closed sales support - not just active listings - is the single most common reason a home sits and eventually requires a price reduction.
• Major cosmetic changes made to personal taste just before listing (bold paint colors, highly specific finishes) can narrow the buyer pool rather than widen it.
• Deferred maintenance items a home inspector will find anyway are generally better addressed before listing than negotiated after an offer, when the leverage has shifted.
