"What is my home worth in Ammon?" has a short answer and a useful one. Short: the median Ammon home is worth about $455,000 in mid-2026, roughly 10% above the Idaho Falls metro. The useful answer depends on your subdivision, your school feed, and your home's condition, and in Ammon those three things move value more than in any other Southeast Idaho submarket. This guide covers where Ammon values sit in 2026, why the premium exists, what growth means for your timing, why the Zillow number is probably behind, and how to get an accurate one for free.

Anchor on the market first. Here's the Ammon snapshot as of mid-2026, from our own closed-transaction data cross-referenced against the Greater Idaho Falls MLS:
Ammon Home Values, 2026 Snapshot (approximate)
Median home value: ~$455,000
Premium vs. Idaho Falls metro (~$415K): ~10%
Typical days on market (priced right): 15–30 days
School district: Bonneville Joint D93
Approximate mid-2026 figures. Sources: Greater Idaho Falls MLS · SR Two70 closed data.
But the median is only the middle of a wide spread. Ammon values band tightly by subdivision and property type, where your home sits inside the city matters as much as its square footage:
| Subdivision / type | 2026 value band | What defines it |
|---|---|---|
| Older Ammon (Sunnyside / 17th corridor) | ~$360K–$450K | 1990s–early-2000s builds, mature trees, walkable, D93 entry point |
| Comore Loma | ~$400K–$560K | Classic Ammon, generous lots, close to schools, strong resale demand |
| Sandcreek Commons | ~$410K–$580K | Established community, clubhouse and pool, repeat-buyer loyalty |
| Taylor Crossing | ~$430K–$620K | Flagship modern family community, pools, parks, fastest turnover |
| Quail Ridge / east Ammon | ~$450K–$700K | Newer semi-custom builds along the Hitt Road corridor, larger lots |
| South Ammon custom / acreage | ~$550K–$1.2M+ | Half-acre to 2-acre lots, custom architecture, premium finishes |
Notice how much the bands overlap. A meticulously kept home in older Ammon can out-sell a tired one in Taylor Crossing. That's why your comp base is your subdivision, not the metro, and why the Ammon number differs from the answer we give across the district line in our Idaho Falls home value guide.

Why the Ammon premium exists, and what it does to your sale price
Ammon trades at a consistent 10–15% premium over equivalent homes in Idaho Falls proper. That premium isn't sentiment; it's three structural advantages buyers pay real money for.
1. D93 schools
This is the single biggest driver. Bonneville Joint School District 93 consistently outperforms Idaho Falls D91 on state testing, and families relocating for INL and healthcare jobs shop the district before they shop the house. Hillcrest High serves most of Ammon, Thunder Ridge the south and east, and the exact feed for your street can add or subtract real dollars, so we verify it before we price anything.
2. Newer construction
Most of Ammon's housing stock is post-2000, much of it post-2010. Buyers read that as less deferred maintenance, modern floor plans, and better energy efficiency, and they discount older homes elsewhere accordingly. If your Ammon home is a 2015 build, your competition is other recent builds, and your value holds a floor an equivalent 1978 home across town never will.
3. Fiber and location
Ammon City Fiber gives the city some of the fastest, most reliable internet in Idaho, a genuine line item for remote workers and relocating professionals, and something no algorithm prices. Add a 15-minute freeway run to the Idaho National Laboratory and 10 minutes to downtown Idaho Falls, and you have a location premium that shows up in every closed sale.
What this means when you sell: you price on the premium, not the metro average. An Ammon seller who anchors to Idaho Falls comps leaves the district premium on the table; one who anchors to the right subdivision band captures it. For the full head-to-head on how the two markets diverge, see our Ammon vs. Idaho Falls comparison.
What a growth market means for timing your sale
Ammon has been Southeast Idaho's fastest-growing city for six of the last seven years, and it has led the metro in appreciation over the same stretch. For a seller, growth cuts two ways, and understanding both sides is the difference between a first-weekend sale and a stale listing.
The tailwind: demand is deep and constant. Correctly priced Ammon homes go under contract in 15–30 days, and the core family subdivisions, Taylor Crossing, Sandcreek Commons, often move in under 20, frequently with multiple offers by Monday. INL engineers, healthcare hires, and out-of-state relocators arrive year-round, keeping a floor under well-presented homes.
The headwind: new construction competes with you. Builders in south and east Ammon release new phases while your home sits on the market, and a buyer weighing your resale against a brand-new floor plan at a similar price takes the new build unless your pricing and presentation give them a reason not to. That's why overpriced Ammon resales sit even while the market around them moves fast. Growth rewards accuracy, not optimism.
The timing takeaway: in an appreciating market, waiting can add value, but only if a new-phase release is not landing the week you list. We track builder inventory and pending phases across Ammon, so part of every valuation conversation is when to go to market, not just at what price.
Why Zestimates lag in fast-growth subdivisions
Automated valuation models (AVMs), the Zestimate and its cousins, are statistical guesses built from public records and past sales. They work best where thousands of near-identical homes trade constantly. Ammon is close to their worst case, and the growth that makes the market strong is exactly what makes the algorithm miss:
- Thin resale history. Newer subdivisions haven't cycled through enough resales for the model to learn them. When Quail Ridge or a new Taylor Crossing phase has a handful of resales on record, the AVM borrows comps from older, dissimilar streets, and the number drifts.
- The comp base keeps changing. Each new construction phase resets what "comparable" means. A model trained on last year's closings is structurally behind in a market appreciating faster than the metro.
- It can't see the premium drivers. The D93 feed for your exact street, Ammon City Fiber, your finishes, your three-car garage on a corner lot, none of it exists in public records the way buyers actually pay for it.
- Boundary blindness. Ammon and Idaho Falls interlock block by block. An AVM that averages across the district line dilutes the very premium you own.
In practice we see algorithmic estimates land 5–10% off the eventual sale price in Ammon, that's $23,000 to $45,000 on a median home, and often more on south Ammon acreage or custom builds. Treat the Zestimate as a conversation starter. Never price on it.
The free human CMA: a real number, built by hand
A CMA, comparative market analysis: is what replaces the guess. We pull the homes that actually closed in your subdivision over the last few months, adjust for what the algorithm can't see (condition, updates, lot, exact school feed), and weigh your home against the active listings and builder phases it will compete with. It's the same core method an appraiser uses, grounded in what's selling on your street this month.
It's free, with no obligation, no listing agreement required to get the number. It's also backed by the track record that makes the number credible: our team has closed 1,000+ homes and $500M+ in career volume across Southeast Idaho, and when you do decide to sell, the same team markets your home with in-house cinematic photography and video seen by an audience of 1M+ monthly content views. The valuation is where that starts, how we turn it into a pricing and marketing plan is on our selling page.

What is the median home value in Ammon, Idaho?
About $455,000 as of mid-2026, roughly 10% above the Idaho Falls metro median of ~$415K. Bands vary widely by subdivision: older Ammon ~$360K–$450K, Sandcreek Commons ~$410K–$580K, Taylor Crossing ~$430K–$620K, and South Ammon custom/acreage ~$550K–$1.2M+. Your subdivision, condition, and school feed set where your home lands inside those ranges.
How accurate is a Zestimate in Ammon?
Typically 5–10% off the eventual sale price, $23K–$45K on a median home. Ammon's newer subdivisions have thin resale history, so the model leans on stale or dissimilar comps, and it can't see the D93 feed, Ammon City Fiber, or your condition and finishes. In a market appreciating faster than the metro, the algorithm is structurally behind. Use it for orientation, not pricing.
Do D93 schools really raise Ammon home values?
Yes, measurably. D93 consistently outperforms Idaho Falls D91 on state testing, and homes feeding into it carry roughly a 10–15% premium over equivalent homes across the district line. It's the biggest single driver of Ammon values, ahead of newer construction and the INL commute. Boundaries shift as subdivisions come online, so verify your exact feed before pricing.
How fast do Ammon homes sell in 2026?
Fastest in the metro: 15–30 days when priced correctly, and often under 20 in Taylor Crossing and Sandcreek Commons, with multiple offers common on the first weekend. The speed only shows up at the right price; buyers comparing your resale to new construction won't chase an overpriced listing. A free CMA shows exactly where that line is.
