Run three numbers and then demand a fourth. First, price the finished home your lot could carry, using documented new build sales of 3,000,000 to 6,500,000 dollars on comparable Park Shore and Moorings waterfront lots (Redfin, 2026). Second, turn that price into a land figure with the residual method, which on a 4,200,000 dollar finished home leaves 1,760,000 to 1,900,000 dollars for land before site preparation (Frontier Capitals, 2026). Third, price the house as a house, honestly, for an occupant buyer. The fourth number, a verified written builder bid, tells you which of the first three estimates the market believes.
The sample shows why the test matters. Builders acquired 11 of 28 sampled older homes in the submarket, while 17 went to other buyers, so the land answer wins often enough to check and loses often enough to respect (Frontier Capitals, 2026). The average older home traded at 32.6 percent of a comparable new build price, a ratio that gives homeowners a fast first screen before they do any detailed work (Frontier Capitals, 2026).

Key Findings
- The residual method converts a finished price into land value: a 4,200,000 dollar new build leaves 1,760,000 to 1,900,000 dollars after roughly 1,600,000 dollars of construction cost and a margin near 20 percent (Frontier Capitals, 2026).
- The quick screen uses the sample ratio: older homes averaged 32.6 percent of comparable new build prices in the 28 home sample (Frontier Capitals, 2026).
- Builders bought 11 of the 28 sampled homes, so land value won in 39.3 percent of screened cases and house value won in the rest (Frontier Capitals, 2026).
- Finished prices on comparable waterfront lots span 3,000,000 to 6,500,000 dollars, with frontage, Gulf access quality and lot size setting the point (Redfin, 2026).
- A failing seawall can subtract six figures from the land figure, while a sound wall protects it, making wall condition part of the test (Frontier Capitals, 2026).
- A 1,600,000 dollar listed sale nets in the low 1,300,000s after a normal cycle, so the house value side of the test must be counted net, not gross (Frontier Capitals, 2026).
What is the first test, pricing the home your lot could carry?
Choose the finished price your specific lot can support, not the neighborhood trophy price. Match your frontage, your canal run to the Gulf and your lot size against the documented range of 3,000,000 to 6,500,000 dollars for new construction on comparable lots (Redfin, 2026). A wide canal lot with quick access belongs high in the range; a small interior lot near the beach belongs where its own recent finished sales cluster.
Recent sold data does the matching work. Look at the newest completed homes on lots most similar to yours, in Park Shore or the Moorings, and note what they actually sold for rather than what they asked (Redfin, 2026). Three honest comparables beat ten flattering ones, because the residual built on a fantasy finished price will produce a fantasy land value that no builder will honor.
Parcel records keep the comparison grounded, since lot dimensions, year built and prior transfers for both your property and the comparables sit in the county file (Collier County Property Appraiser, 2026). If a comparable sits on twice your frontage, its finished price needs an adjustment before it enters your test, and the adjustment should be written down where a bidder can challenge it.
How does the second test, the residual, turn price into land value?
Subtract the project from the prize. From your chosen finished price, remove roughly 1,600,000 dollars of hard and soft construction costs as illustrated in the research, remove a builder margin near 20 percent, and note what remains before site preparation of 40,000 to 60,000 dollars (Frontier Capitals, 2026). That remainder is the ceiling on land value for a normally efficient builder, and most bids will land somewhat under the ceiling.
Sensitivity check the result before trusting it. Drop your finished price by 10 percent and rerun the subtraction; if the land figure collapses, your property value hangs on an optimistic assumption and deserves a second look at the comparables (Redfin, 2026). Raise construction costs modestly and rerun it again. A land conclusion that survives both stresses is sturdier than one that needs every input at its friendliest.
Then apply the fast screen as a cross check. Multiply the finished price by 32.6 percent, the average relationship the sample found between older homes and new builds (Frontier Capitals, 2026). If the screen and the residual point to similar territory, your estimate has two independent supports. If they diverge wildly, one of your inputs is wrong, and finding out which is the cheapest diligence you will ever do.
The worked example from the research anchors the method: against a 4,200,000 dollar finished home, the ratio implies an older original near 1,369,000 dollars while the detailed residual allows up to roughly 1,900,000 dollars for the land before site costs (Frontier Capitals, 2026). The gap between those figures is the negotiating field on which real bids play out, explored further in how much a residential lot is worth in Park Shore and Moorings.

What is the third test, pricing the house honestly as a house?
Now change hats and value the home for the family who would live in it. That buyer pays for shelter, water and the chance to skip years of construction, and they compare your home against other standing homes rather than against a building site (Zillow, 2026). Recent sales of similar standing homes in Park Shore and the Moorings, adjusted for condition, form the evidence.
Condition adjustments must be unsentimental. The research illustration shows 160,000 dollars of renovation adding 110,000 to 140,000 dollars of price for an occupant buyer, which means even good renovation returns less than it costs in this dataset (Frontier Capitals, 2026). An unrenovated original should therefore be priced as an unrenovated original, with the buyer discount for future work built into the expectation.
Automated estimates can open this conversation but cannot close it. Zillow publishes a nationwide median error of 1.9 percent for on market homes and 7.5 percent for off market homes, and on a seven figure waterfront property the wider band alone is a six figure swing (Zillow, 2026). Flood disclosure obligations also belong in an honest house pricing, because Florida law requires seller flood disclosure and buyers price what disclosures reveal (Florida Senate, 2025).
Finally, convert the house price to a net. A listed route at 1,600,000 dollars surrenders 80,000 to 96,000 dollars to commissions at 5 to 6 percent and another 1 to 2 percent to seller closing costs, with the pair commonly exceeding 110,000 dollars (National Association of Realtors, 2025). Seller closing cost references itemize the stamp tax, title, settlement and recording charges behind the smaller percentage (Bankrate, 2026). Comparing a gross house price against a net land bid is the most common way homeowners fool themselves in this test.
What role do the seawall and site facts play in the test?
They adjust the land side, sometimes decisively. A failing seawall can subtract six figures from a land bid and replacement alone can run into six figures, so a canal property with a tired wall must shade its residual down before comparing (Frontier Capitals, 2026). A documented sound wall keeps the full figure in play.
Site preparation of 40,000 to 60,000 dollars already sits inside the research illustration as a separate deduction, covering the work of readying the lot (Frontier Capitals, 2026). Unusual clearing, access difficulty or dock removal can push a real project beyond that band, and a builder walk through will surface those items earlier than any spreadsheet.
Title facts adjust both sides. Recorded liens or judgments in county files must be resolved for any sale, and discovering them during your own test beats discovering them at a closing table (Collier County Clerk of Courts, 2026). Clean facts make both the land number and the house number more believable to the buyers who will eventually test them.
What is the fourth number, and why does it outrank the other three?
A verified written builder bid. Estimates, ratios and residuals are arguments; a bid backed by proof of funds in the buyer name dated within the last 30 days and covering the full price is evidence (Frontier Capitals, 2026). Earnest money of typically 1 percent or more and a contract that closes in the buyer name with no assignment clause complete the credibility checklist.
Solicit the bid on the strength of your test results. An owner who can show three finished comparables, a survey and seawall records invites builders to bid against documents rather than against uncertainty, and uncertainty always bids lower (Collier County Property Appraiser, 2026). Two bids are better than one, because the spread between them maps the real negotiating range; the tactics for drawing several are set out in how much a builder will pay for an older house in Park Shore and Moorings.
If the verified land bid exceeds your honest net house value, the property is worth more as land, and the remaining decision is timing and terms. If it falls short, the house is the asset, and listing or holding both stay rational. Either way the test has done its work, which is to replace a hunch with arithmetic.
Do not forget the market backdrop while running the numbers. Naples recorded 61.1 percent of sales paid in cash in the July 2026 snapshot, so cash builder bids land in a market that understands and trusts them (Realty.com, 2026). Buyer agent commissions held near 2.42 percent in late 2025 commission research, confirming the traditional deduction stack used in the house side of the test (Redfin, 2025).
How does selling as land change the closing itself?
The practical advantages of the land route read like a list of things that do not happen. No showings, no open houses and no public marketing period, so the sale stays private until the deed records. No commissions, preserving the 80,000 to 96,000 dollars a 1,600,000 dollar listed sale would pay away (National Association of Realtors, 2025). No seller closing costs in the standard direct structure, no repair credits of 10,000 to 30,000 dollars and no waterfront concession rounds of 25,000 to 75,000 dollars, because the home sells as is.
The calendar bends to the seller instead of the market. A direct closing can settle in 7 to 21 days when speed helps, or wait months with a leaseback style arrangement when the seller needs time, against 60 to 120 or more days for a listed older home (Frontier Capitals, 2026). Avoiding 4 to 8 months of carrying costs, which run 50,000 to 150,000 dollars with wind and flood insurance able to pass 2,500 dollars a month, can itself tip a close test toward land.
Frontier Capitals sources off-market deals to builders; it is not a builder and does not bid for its own account in this process. Its role is to run the private builder side of the test for an owner, with the numbers shown, and it can be contacted at 401-219-4207 or [email protected].

What mistakes most often corrupt the test?
The first mistake is grading the finished price with trophy sales. Picking the single highest new build closing in the submarket, at the top of the 3,000,000 to 6,500,000 dollar range, and applying it to an interior lot manufactures a land value no bidder will validate (Redfin, 2026). Comparables must resemble your lot in frontage, access and size, or the whole arithmetic leans.
The second mistake is comparing a gross house price to a net land bid, counted earlier in this report and repeated here because it ruins more kitchen table calculations than any other error (Frontier Capitals, 2026). Commissions, closing costs, concessions and carrying months belong inside the house figure before any verdict is announced to the family.
The third mistake is trusting one automated estimate as the house side of the test. With a published median error of 7.5 percent for off market homes, a single automated number can be wrong by more than the entire gap the test is trying to measure (Zillow, 2026). Sold comparables and, where possible, an agent opinion built from them make a sturdier house figure.
The fourth mistake is stopping at estimates. A test that never solicits a verified bid remains a theory, and in this submarket the bid is obtainable without listing, showing or spending anything beyond a conversation (Frontier Capitals, 2026). Arithmetic points the way; only the market signs the answer.
Methodology and limitations
The test described here assembles tools from the underlying Park Shore research: a 28 home sample screened toward likely builder acquisitions, the 32.6 percent average price relationship from that sample, and a simplified residual illustration that its authors label as an illustration rather than a promise (Frontier Capitals, 2026). No verified single figure can declare an individual property worth more as land without live bids, and this report states that limit plainly.
No title search, home inspection, seawall engineering review or flood zone determination was performed for the sample properties. Individual outcomes will vary with frontage, access, lot shape and condition in ways a general method can frame but not settle.
Conclusion
A homeowner determines the land question by pricing the finished home the lot supports, subtracting construction and margin to reach the land ceiling, pricing the standing house honestly and converting that price to a net, then letting a verified builder bid arbitrate between the two estimates (Frontier Capitals, 2026). In the sample that arbitration favored land 11 times in 28, which is often enough that no Park Shore owner should sell the house without running the test (Frontier Capitals, 2026). If you ran your own three numbers tonight, which side of the comparison would you expect to win, and what would you do if the bid disagreed?
Frequently Asked Questions
What is the fastest version of the land test?
Multiply a realistic finished price for your lot by 32.6 percent, the sample average relationship, and compare that figure with what occupant buyers would net you after commissions and closing costs (Frontier Capitals, 2026). The screen takes minutes, and the full residual and bid process can then confirm or overturn it.
Can my house be worth more as land even if it is in good shape?
Yes, when the lot supports a finished price high enough that the residual clears the honest house value, condition does not save the house side of the comparison (Frontier Capitals, 2026). Good shape matters only through the occupant price it can command.
Which documents make my land estimate most credible?
A current survey, seawall records, dock details and three sold comparables for new construction on similar lots, checked against county parcel records (Collier County Property Appraiser, 2026). Bidders discount what they cannot verify, so paper raises bids.
How do I know a builder bid is genuine?
Require proof of funds dated within the last 30 days in the buyer name covering the full price, earnest money of typically 1 percent or more, and a contract with no assignment clause that closes in the buyer name (Frontier Capitals, 2026). A bidder unwilling to meet those three tests has offered a talking point rather than a purchasable commitment for your lot.
What if the two sides of my test come out nearly equal?
Then terms decide: privacy, a 7 to 21 day closing or a delayed leaseback closing, no commissions and an as is transfer can outweigh a small gross price edge on the listed side (Frontier Capitals, 2026). Count carrying costs for both timelines before calling it a tie.
