Capstone Homes sells a 2,488-square-foot, two-story floor plan called Plan 2488 in two of its Timber Sky collections. In Corvus it starts at $824,900. In Sirius it starts at $912,900. That's the same plan with an $88,000 difference in price. Now look at the quick move-in versions listed for sale this fall. A Corvus Plan 2488 at 3693 W Styx Lane, listed "Available Now," is priced at $888,338, and a Sirius Plan 2488 at 3149 W Virgo Drive, listed "Available October 2026," is priced at $896,171. On those two specific homes, the $88,000 gap has shrunk to $7,833.
That shrinking gap is the most useful pricing fact in Timber Sky right now. A starting price tells you where a build-to-order contract begins. A quick move-in home's price tells you what a specific house on a specific lot actually costs. In Timber Sky, those two numbers behave differently in each collection.
Two price sheets for the same plans
Corvus and Sirius are both Capstone collections inside the same master-planned community, off Route 66 between Flagstaff Ranch Road and Woody Mountain Road. Corvus has 61 homesites and is "located across from the community amenities area," close to the trails, dog park, pickleball courts, and ramada. The Sirius brochure lists 63 total homes.
Two plans appear on both price sheets with identical square footage and a 2-car garage:
| Plan | Corvus starting price | Sirius starting price | Difference |
|---|---|---|---|
| Plan 2013, 2,013 sq. ft. | $739,900 | $820,900 | $81,000 |
| Plan 2488, 2,488 sq. ft. | $824,900 | $912,900 | $88,000 |
A buyer comparing those sheets would conclude that Sirius costs about $80,000 to $90,000 more for the same house. The quick move-in inventory doesn't support that conclusion.
What the price does on a specific homesite
Capstone lists quick move-in homes in both collections. These are specific houses on numbered homesites, each with its own listed price and availability date. Put each one next to its plan's starting price and a pattern shows up.
| Collection | Address | Plan | Listed price | Starting price for plan | Gap |
|---|---|---|---|---|---|
| Corvus | 3725 W Styx Lane | 1793 | $751,935 | $714,900 | +$37,035 |
| Corvus | 3671 W Styx Lane | 1985 | $786,829 | $744,900 | +$41,929 |
| Corvus | 3717 W Styx Lane | 1985 | $790,453 | $744,900 | +$45,553 |
| Corvus | 3701 W Styx Lane | 1985 | $796,516 | $744,900 | +$51,616 |
| Corvus | 3693 W Styx Lane | 2488 | $888,338 | $824,900 | +$63,438 |
| Corvus | 3677 W Styx Lane | 2488 | $894,708 | $824,900 | +$69,808 |
| Sirius | 3157 W Virgo Dr | 2013 | $826,579 | $820,900 | +$5,679 |
| Sirius | 3149 W Virgo Drive | 2488 | $896,171 | $912,900 | −$16,729 |
| Sirius | 3149 W Nix Way | 2467 | $940,565 | $929,900 | +$10,665 |
| Sirius | 3165 W Nix Way | 2631 | $1,027,197 | $919,900 | +$107,297 |
Every Corvus quick move-in home is listed between $37,000 and $70,000 above its plan's starting price. Three of the four Sirius quick move-in homes sit within about $17,000 of theirs, and the Plan 2488 is listed below its own starting price. The exception is the Sirius Plan 2631 on Nix Way, which runs $107,297 over its starting price.
So the Corvus starting price is the number that rises once a house is tied to a specific homesite. The Sirius starting price mostly stays put. The Corvus home at 3677 W Styx Lane, which lists 4 baths, is just $1,463 below the Sirius version on Virgo Drive.
These aren't perfect matches. Each home sits on a different homesite with its own selections, and the Corvus homes carry extras, covered below. Even so, the sheets suggest a much wider gap than the quick move-in homes show.
The feature sheets don't explain the premium
If the Sirius premium paid for a better standard house, Capstone's included-features sheets would show it. They don't make that case. Both collections list 10-foot first-floor ceilings, 9-foot second-floor ceilings, and 8-foot interior doors. Where the sheets differ, each collection comes out ahead on some items:
- Garage door. Corvus lists an "8' Wayne Dalton® Steel Garage Door with foamed-in-place insulation." Sirius lists an "8' Non-Insulated Garage Door."
- Range. Corvus specifies a 30-inch five-burner gas range. Sirius specifies a 30-inch range without stating the fuel.
- Car charging. Sirius lists a "50 AMP Car Charger Outlet." The Corvus Homesite 67 listing says all homes in the series include a 220v electric car plug in the garage, though the Corvus features sheet doesn't list one.
- Tile. Sirius uses 12-by-24-inch tile in full bathrooms and laundry. Corvus uses 12-by-12-inch tile and lists a semi-frameless glass enclosure at the primary shower.
Capstone doesn't classify the collections as tiers. Its Timber Sky page describes "seven distinctive neighborhoods," each with "a unique collection" of homes. The builder's pages don't give a reason for the starting-price gap. Elevation choices also differ: the Sirius brochure shows an Elevation C for Plan 2013, and the Corvus pages show Elevations A and B. A buyer who wants to know what the Sirius premium pays for has to ask the sales team, homesite by homesite.
How the builder adjusts price without changing the number
Corvus also shows how a builder moves ready inventory when the market slows. All six Corvus quick move-in homes are listed "Available Now." The community page says "Backyard landscaping including built in BBQ are included in these limited move-in ready homes!" The Homesite 67 listing says the home "will now include backyard landscaping as well as built-in BBQ." The words "will now" point to a recent change. The price stayed where it was and the house got more.
Capstone doesn't put a dollar value on that landscaping. It does mean that a Corvus quick move-in home's price buys more than the features sheet describes, and the $888,338 Corvus Plan 2488 includes an outdoor package the Sirius listing doesn't mention.
The broader Flagstaff market gives builders a reason to sweeten deals this way. Realtor.com data published through FRED counted 765 active listings in the Flagstaff metro area in September 2026, down from 778 in August. Over the same months, median days on market rose from 79 in August 2026 to 88 in September 2026. Inventory held roughly steady while homes took longer to sell. A builder with six houses listed "Available Now" has carrying costs on every one.
Sirius runs on a different calendar. As listed on Capstone's site this fall, its quick move-in homes become available in stages, with Plan 2488 on Virgo Drive in October 2026, Plan 2013 in November, Plan 2467 on Nix Way in December, and Plan 2631 in January 2027. A buyer looking at the January home is buying a house scheduled to become available in the middle of a Flagstaff winter. Its listed price or inclusions may change as that date gets closer, since the Corvus homes listed "Available Now" have picked up landscaping and a built-in BBQ.
Reading a Timber Sky price sheet in the right order
The pattern above points to a better order for comparing Capstone's two collections:
- Start with quick move-in homes, not starting prices. The quick move-in Plan 2488s in Corvus and Sirius are listed $7,833 apart. That's the comparison that holds up against a real house.
- Treat a starting price as an opening number. In Corvus, every quick move-in home is listed tens of thousands of dollars above its plan's starting price. Build that range into your budget if you're considering a new build there.
- Add up what's included before comparing. Landscaping, a built-in BBQ, an insulated garage door, and a car-charging outlet are all real line items, and the two collections don't include the same ones.
- Ask about the specific homesite. Capstone's materials don't explain the Sirius premium, so the sales center is the only place to learn what a given lot carries.
- Ask about financing separately from price. Capstone names Intercap Lending as its preferred lender and lists temporary and permanent rate buydowns among its loan program types. The page gives no specific rate, credit amount, or deadline. A financing incentive affects your monthly payment differently than a price change does, so get each one in writing.
