On the one fully documented illustration in the Redmond research, the builder margin on a teardown project sits near 20 percent of the finished sale price. The illustration works from a new build sale of 2,200,000 dollars, subtracts roughly 850,000 dollars in hard and soft construction costs, and applies a builder margin near 20 percent, leaving a residual land value in the neighborhood of 910,000 to 1,010,000 dollars before site preparation costs of 25,000 to 40,000 dollars (Frontier Capitals, 2026). Twenty percent of 2,200,000 dollars is 440,000 dollars, which is the gross margin the illustration assigns to the builder before the risks and overheads of an actual project are considered. That figure must be labeled carefully: it is an illustration of how the math is structured, not a measured average of what Redmond builders earned across real projects, and this report treats it that way throughout. New construction on standard lots in 98052 has sold from 1,800,000 to 2,800,000 dollars depending on street, hill versus flat position, and lot size (Redfin, 2026), so the margin in dollars moves widely with the finished price even when the percentage holds.
Sellers ask this question for a practical reason, because the builder margin is the slice that determines how much room exists to pay for the land. Every dollar of margin the builder protects is a dollar the land bid cannot contain, and every dollar of cost overrun comes out of the same pocket. Understanding the structure helps a seller read an offer intelligently: a bid is not a guess about generosity, it is the residue of a calculation. The sample behind this report shows how often that calculation leads to a purchase, with builders acquiring 13 of 36 sampled homes built in 1980 or earlier in 98052 (Frontier Capitals, 2026). Sellers who want the offer side of the same math can read how much a builder will pay for an older house in Redmond next.
Key Findings
- The documented residual illustration applies a builder margin near 20 percent to a 2,200,000 dollar new build sale, equal to roughly 440,000 dollars of gross margin inside the illustration (Frontier Capitals, 2026).
- The same illustration subtracts roughly 850,000 dollars in hard and soft construction costs and leaves residual land value near 910,000 to 1,010,000 dollars before site preparation of 25,000 to 40,000 dollars.
- The 20 percent figure is an illustration assumption from the research, labeled as simplified, and not a measured average across Redmond builder projects.
- New construction prices from 1,800,000 to 2,800,000 dollars on standard lots mean the dollar margin at a similar percentage ranges broadly by street and lot (Redfin, 2026).
- Builders acquired 13 of 36 sampled older homes in 98052, which shows the margin structure supports active purchasing at documented land prices (Frontier Capitals, 2026).
How is the builder margin in the Redmond illustration actually built?
The illustration is a residual calculation, and each line has a job. The starting line is the expected sale price of the finished home, set at 2,200,000 dollars because that figure sits inside the documented new construction band for standard lots and pairs with the worked example of an older ranch selling near 763,000 dollars at the 34.7 percent ratio (Frontier Capitals, 2026). The second line subtracts hard and soft construction costs of roughly 850,000 dollars, covering the physical build together with design, permitting, financing, and related soft expenses as a combined documented figure. The third line reserves the builder margin near 20 percent. What remains is the amount the project can pay for the land and still satisfy its own economics.
That remainder, the residual land value near 910,000 to 1,010,000 dollars, is the number a seller actually negotiates over, and site preparation costs of 25,000 to 40,000 dollars come out of the project before the landowner sees a final bid shaped by a specific lot. A sloping parcel, a difficult access point, or utility work can move a real bid below the illustration range, while a flat, regular, well located lot can support the top of it. Parcel records document the dimensions and characteristics that feed those adjustments (King County Assessor, 2026), which is why builders study county files before they study the house. The county parcel and permit records also show what was previously approved and built on the site (King County Department of Assessments, 2026), and a clean permit history removes one more unknown that would otherwise be priced into the margin as caution.
Margin, in this structure, is not the same as take home profit, and the distinction matters for honest discussion. The 20 percent reserve must absorb estimating errors, price movement during a long build, carrying costs on construction financing, warranty obligations, and the overhead of running a building company between projects. A project that finishes on plan converts much of the reserve into profit, while a project with a foundation surprise or a softening market can consume the reserve entirely. Sellers sometimes imagine the margin as money extracted from their price, when the arithmetic shows it functioning more like a risk budget that the land bid already reflects.
Recorded deeds provide the reality check on the whole structure. Deeds filed under builder entity names show the land prices builders actually paid across the sample (King County Recorder, 2026), and those prices, set against the new build prices recorded later on the same lots, reveal whether the illustration percentages resemble lived outcomes on a given street. No public record in the pool reports a builder final profit, which is exactly why this report refuses to present the 20 percent as a measured average. The illustration explains structure, the deeds explain prices, and neither pretends to be the other.
Why does the dollar profit vary so much between Redmond projects?
The finished price band does most of the explaining. At a margin near 20 percent, a new build selling at 1,800,000 dollars carries roughly 360,000 dollars of margin inside the same structure, while a build selling at 2,800,000 dollars carries roughly 560,000 dollars. Street, hill versus flat position, and lot size drive a property toward one end of that band or the other (Redfin, 2026). Education Hill premiums visible in new build comparables lift the top line for projects there, while a constrained lot near downtown Redmond may cap the finished size and hold the price lower even when demand is strong.
Costs vary with the same geography. The documented construction figure of roughly 850,000 dollars is an illustration midpoint, and real projects bend around it according to finished size, specification level, and site conditions. Housing age and condition data for King County describes the stock being replaced (U.S. Census Bureau, 2025), yet the replacement cost belongs to the new structure, and a larger finished home on the lot consumes margin through cost even as it adds price. Builders who misjudge that balance discover that a higher sale price can coexist with a thinner final profit, which is why experienced builders bid land from conservative finished price assumptions.
Market timing adds a third source of variation that no illustration can freeze. A spec project commits land and construction money many months before the finished home meets its buyer, and the referenced mortgage survey placed the 30 year fixed rate at 7.28 percent for the week ending October 1, 2026 (Freddie Mac, 2026), a reminder that financing conditions shape both builder carrying costs and buyer capacity at the far end of the project. A margin reserved at purchase can be squeezed by rate movement before the sale ever occurs. That exposure is priced into land bids as caution, and sellers who understand it stop reading a careful bid as a personal judgment on their home.
The land price itself is the final variable, and it connects this report to the seller side of the table. Where several builders compete for the same street, bids can press the margin thinner than the illustration, because each builder would rather accept a smaller reserve than lose the lot. Where a lot fits only one builder program, the bid can sit at the full illustration margin or beyond. Sellers can influence which situation they face by making the property visible to more than one builder, a theme developed in how Redmond homeowners attract multiple offers from builders.
What does the margin structure mean for a Redmond seller negotiating with a builder?
A seller who understands the residual structure negotiates over the right line. Arguing that a builder should simply accept less profit rarely moves a bid, because the margin defends the project against documented risks. Arguing from the inputs works better: comparable finished prices on the same street, evidence that the lot is flat and regular, permit history that reduces unknowns, or a closing calendar that saves the builder carrying time. Each input argument raises the residual, and a raised residual is where higher bids actually come from.
Online home value platforms follow the older house and its recorded sales rather than the project that may replace it (Zillow, 2026), so an estimate for the existing home says nothing about the margin structure behind a builder bid. Sellers should also compare builder bids against the household route on a net basis before judging them small. A listed sale of an older home at 900,000 dollars commonly nets the high 700,000s to low 800,000s after commissions of 5 to 6 percent, seller closing costs, concessions of 10,000 to 25,000 dollars, and carrying costs of 18,000 to 36,000 dollars across the market cycle (National Association of Realtors, 2025). A builder bid that looks modest beside a hoped for list price can look quite different beside the documented net of the listed route, particularly when the builder bid closes in 7 to 21 days without a repair program. The comparison belongs on one page, with every line visible.
Verification protects the seller share of the structure. A genuine builder or direct buyer shows proof of funds dated within 30 days, points to recorded deeds in the buyer entity name (King County Recorder, 2026), posts earnest money of typically 1 percent or more, and signs a contract with no assignment clause. Those markers matter in profit discussions because a party planning to resell the contract needs a spread of its own, which comes out of the land price. A seller who eliminates that hidden spread has effectively negotiated a raise without arguing about margin at all. Excise tax at closing follows the state graduated rules on the agreed price (Washington Department of Revenue, 2025), whichever buyer signs.
Owners who want a second builder perspective on the same lot can also review what builders recently paid for teardown properties in Redmond, where the deed evidence is laid out as prices rather than percentages. The two views, structure and record, together give a seller the complete picture this research can honestly offer. Anything beyond it, including a claim about average builder profit across the city, would require project cost books that no source in the pool contains.
What do sellers keep when a Redmond sale stays off market?
Privacy is the first gain, because an off market negotiation over land value never becomes a public listing with a price the whole street can track and discuss. The seller explores builder interest quietly, involving zero showings and zero open houses, and the first public fact is the recorded deed. For a family selling a home that will be replaced, that discretion avoids months of neighborhood speculation about plans and prices.
Flexible closing is the second gain, and builders use the same flexibility in reverse, since a seller who can align possession with a builder project calendar becomes easier to bid strongly for. A direct sale can close in 7 to 21 days when the seller wants speed, or it can be set months out with a leaseback when the household needs time. A listed older home commonly needs 60 to 120 plus days from list to close, plus the uncertainty of a household buyer financing chain that a teardown negotiation simply does not contain.
Commission savings are the third gain, and they interact with the margin question directly. On a 900,000 dollar sale, the standard 5 to 6 percent commission claim amounts to 45,000 to 54,000 dollars (National Association of Realtors, 2025). A seller worried that a builder margin trims the land bid should also count the commission a listing would trim from the household price, because both deductions are real and only one of them is usually discussed. An off market sale carries no listing commission at all.
The fourth gain concerns what the seller pays at the closing table itself. Title, transfer and excise taxes, and prorations commonly add 1 to 2 percent on the seller side of a listed transaction, and commissions plus closing costs together commonly take 54,000 to 72,000 dollars on a 900,000 dollar sale. Frontier Capitals direct terms lift that seller side closing cost burden off the seller altogether. In a negotiation where the parties are arguing over percentage points of margin, a seller who quietly keeps an additional 1 to 2 percent has won a point that rarely makes the headline.
The fifth gain is the absence of inspection and repair bargaining. A household buyer on an older home routinely reopens price through credits and reductions of 10,000 to 30,000 dollars after inspection. A builder buyer has already priced the structure at its role in the project, which is to say barely at all, so the as is sale proceeds on the land number agreed at signing. The seller never spends a dollar defending the condition of a house the buyer plans to replace.
The standing disclosure belongs in any profit discussion, because it clarifies who earns what. Frontier Capitals sources off market deals to builders and works as a wholesaler in the technical sense, and it never claims to be the builder or to earn a construction margin. The seller protection is verification: proof of funds dated within 30 days, recorded deeds in the buyer entity name, earnest money of typically 1 percent or more, and no assignment clause in the contract. A seller who runs those checks knows the margin being discussed belongs to an actual builder with an actual project. Sellers ready to open that conversation can use the contact page.
Methodology and limitations
The profit discussion in this report rests on a single documented residual illustration in the underlying research, structured around a 2,200,000 dollar new build sale, roughly 850,000 dollars in hard and soft construction costs, a builder margin near 20 percent, and site preparation of 25,000 to 40,000 dollars, with the illustration labeled as simplified in the source material. No source in the pool reports audited or average builder profit across Redmond projects, and this report therefore presents the percentage as structure rather than as a measured outcome. The market context comes from the sample of 36 homes built in 1980 or earlier in 98052, of which 13 were acquired by builders (Frontier Capitals, 2026), a sample rather than a census of the ZIP code. No inspection and no title search were performed for this report, and individual project and sale figures will vary by lot, street, and the specification of the finished home.
Conclusion
Spec builder profit on a Redmond teardown project, as far as documented evidence can state it, is a margin near 20 percent inside a residual illustration built on a 2,200,000 dollar finished sale, equal to roughly 440,000 dollars of gross margin before project risks and overheads take their share. Sellers serve themselves best by negotiating the inputs to that structure, comparable finished prices, lot quality, and calendar, and by comparing any bid against the documented net of the listed route rather than against a hoped for gross price.

Frequently Asked Questions
Is the 20 percent builder margin a measured average for Redmond?
No. The figure is an illustration, and the report keeps that label on it throughout. The near 20 percent figure is the margin assumption inside a documented residual illustration that the source research itself calls simplified (Frontier Capitals, 2026). No source in the pool publishes average realized builder profit for the city, so any figure presented as a measured average would be invented. The illustration remains useful because it shows how land bids are constructed.
How much is 20 percent on the prices Redmond new builds actually achieve?
Applied across the documented new construction band, a margin near 20 percent equals roughly 360,000 dollars on a 1,800,000 dollar sale and roughly 560,000 dollars on a 2,800,000 dollar sale (Redfin, 2026). Those are arithmetic applications of the illustration percentage to documented prices, not reports of money any specific builder earned. Street, slope, and lot size decide where a given project lands inside the band.
Why do builders protect the margin instead of paying more for land?
Because the margin absorbs the risks the illustration cannot itemize: cost overruns, financing carry at rates such as the 7.28 percent documented in the referenced survey (Freddie Mac, 2026), market movement during the build, and company overhead. A builder who bids the margin away to win one lot has no reserve when that project surprises them. Sellers raise bids more effectively by improving the inputs, lot evidence and closing speed, than by arguing against the reserve itself.
Can competing builders produce a bid above the illustration residual?
Competition can press a builder to accept a thinner margin reserve for a desirable lot, which raises the land bid above the illustration path for that address. Parcel records showing a large, regular lot (King County Assessor, 2026) and deed evidence of strong nearby builder prices both support that pressure. The surest way to create the situation is to let more than one qualified builder price the property, with verification checks applied to each.
How do I know whether a buyer margin discussion is honest?
Ask the buyer to show the structure: expected finished price from street comparables, construction cost line, margin reserve, and the resulting land figure. Then verify the buyer independently through proof of funds dated within 30 days and recorded deeds in the buyer entity name (King County Recorder, 2026). A buyer who welcomes both steps is discussing a real project, while a buyer who resists verification may be protecting a contract resale spread instead of a construction margin.
