By Aidan Sowa · October 2026 · St Simons Island, GeorgiaBy running two valuations side by side and believing the larger one. The first valuation prices the property as land, using the residual method documented in the island research: finished new build price, minus construction costs, minus builder margin, minus site preparation, equals what the ground can support. The second prices it as a home, using what a live-in buyer would pay for the house as it stands. On St Simons Island the land valuation wins surprisingly often, because older homes in the sample averaged only 23.1 percent of the price of new construction on a comparable lot (Frontier Capitals, 2026).
The worked illustration shows the scale of the land side. A finished sale at $1,500,000, minus roughly $620,000 in hard and soft construction costs and a builder margin near 20 percent, leaves residual land value near $550,000 to $650,000, before $20,000 to $35,000 in site preparation (Frontier Capitals, 2026). At a $1,400,000 price point for the finished home, the older house sitting on a similar parcel sold for about $325,000. Any owner whose livable home value sits below the residual for the lot is, in market terms, sitting on land with a house on it rather than the reverse.
The test is not a guess or a slogan. It is built from recorded finished prices, parcel records and one honest question about the house itself, and the framing distinction is spelled out in the difference between a home market value and its land value. Owners in estates and other shared ownership situations need the same test, which is why the probate discussion in how a house can be sold during probate leans on documented valuation rather than family estimates.
Key Findings
- Older homes in the sample averaged 23.1 percent of new build prices on comparable lots, with builders acquiring 9 of 17 sampled homes (Frontier Capitals, 2026).
- Residual land value in the worked illustration runs near $550,000 to $650,000 on a $1,500,000 finished sale, before $20,000 to $35,000 in site preparation (Frontier Capitals, 2026).
- Sales of homes built recently on ordinary parcels fall between $1.1M and $1.9M, a spread explained in part by distance to the beach or marsh and by parcel size (Redfin, 2026).
- A $75,000 renovation illustration returns $50,000 to $65,000 for a live-in buyer and nothing where the buyer acquires the lot (Frontier Capitals, 2026).
- The smallest sampled lot measured 6,098 square feet, so the land test applies even to modest island parcels (Frontier Capitals, 2026).
What is the first step in running the land valuation?
Gather the finished prices for the segment the property actually sits in. Location leads the residual factors in the research: beachfront and marsh view premiums appear in new build prices but rarely in older home listings, so a Village lot must be tested against Village finished sales, a corridor lot against corridor sales, and a mid-island lot against mid-island sales (Frontier Capitals, 2026). Recorded island sales provide those figures (Redfin, 2026), and the wider resale picture across the island single ZIP code is summarized in which ZIP codes have the highest home resale values, a useful reminder that 31522 contains several distinct price segments inside one code.
Then subtract honestly. Construction costs near $620,000 and a margin near 20 percent in the illustration are not padding invented to shrink the land figure. They are the documented blocks a builder must fund before paying anything for ground, with site preparation of $20,000 to $35,000 still to come (Frontier Capitals, 2026). An owner who runs the subtraction with real finished prices from the correct segment arrives at a land range that a real bid should resemble. A bid far below that range invites a second bid. A bid inside it is evidence, not an insult.
House price movement in coastal Georgia supplies background for how stable those finished prices are (Federal Housing Finance Agency, 2026). The residual is only as reliable as the finished prices beneath it, which is why current recorded sales matter more than a hopeful listing on the same street.
What is the second step in pricing the home as a home?
Price the house the way a live-in buyer will: by its systems, its condition and its competition among livable homes, not by its memories or its renovation history. Online estimates are a starting glance and no more, because valuation tools draw on nearby sales that may include new construction at prices no older home will achieve (Zillow, 2026). The deed record separates what older homes actually achieved from what finished homes achieved nearby (Glynn County Clerk of Superior Court, 2026).
The research names the one profile that reliably beats its land value: a genuinely livable, well kept home with updated systems and no functional obsolescence, sold as a home rather than as a homesite. If the house fits that profile, its home value can exceed the residual and listing becomes the profitable test. If it does not, the renovation shortcut rarely rescues it. The documented illustration is sobering: $75,000 spent on a 1968 cottage might add $50,000 to $65,000 for a live-in buyer, a loss on the spend itself, and it adds nothing at all where the buyer wants the lot (Frontier Capitals, 2026).
Owners should also net the home value honestly. A listed sale at $550,000 carries commissions of $27,500 to $33,000 and closing costs of 1 to 2 percent, with repair credits and months of carrying costs behind them, netting in the mid-$400,000s on the research ledger (Frontier Capitals, 2026). Comparing a gross list estimate against a net land bid rigs the test, and rigged tests produce expensive decisions.
What lot evidence can move the answer either way?
Three documented factors, in the research order. First, position, already covered: segment and view set the finished price ceiling. Second, lot size and buildable footprint. The sampled minimum of 6,098 square feet shows the scale at which builder acquisition already operates, and parcel records carry the dimensions and flood zone designations that define the usable envelope (Glynn County Board of Assessors, 2026). A wide, clean, fully buildable lot raises the land figure. A narrow or heavily constrained lot lowers it, sometimes below the home value of a sound house standing on it.
Third, elevation and flood compliance, which cap what can be built and therefore what the ground is worth. Flood maps and permit records document the regulatory position lot by lot (Glynn County, 2026), and flood insurance pricing under Risk Rating 2.0, with elevation certificate requirements, shapes the carrying costs that finished buyers weigh (Federal Emergency Management Agency, 2026). A low lot in a demanding zone can carry a land value well below its size suggests, while an elevated modest lot can surprise its owner in the other direction.
The lot side of the test has its own full treatment in how much a residential lot is worth, which owners can use to check a residual result against the island lot evidence before seeking bids. Parcel and permit history from the tax records completes the file (Glynn County Tax Assessor, 2026).
How does a direct bid settle the question?
Because a bid is the only valuation that comes with money attached. Estimates, residuals and opinions all point, but a written offer from a verified buyer states what the land side will actually pay, on a stated date, and the home side can then be tested against a real number instead of a theory. The verification discipline from the research applies: proof of funds in the buyer name dated within the last 30 days, and recorded deeds in the buying entity name from closed purchases, checkable in county records (Glynn County Clerk of Superior Court, 2026).
Multiple bids sharpen the answer further. Where two or three builders price the same lot from the same finished sales, their spread reveals how each reads the envelope and elevation, and the owner learns the land value from the market rather than from a single opinion. Frontier Capitals, as a wholesaler sourcing off-market deals to builders and buying directly from sellers, sits in that bid process without claiming to be a builder itself.
The answer also carries obligations owners should not skip. Even where the land value wins and the sale proceeds as-is, Georgia disclosure duties for known material conditions still apply, and the figures in this report do not change what a seller must share. Where a mortgage stands against the property, the payoff arithmetic decides what the seller keeps, a situation worked through in whether a house can be sold for more than the mortgage balance during foreclosure, where the balance is paid from proceeds at closing and the remainder stays with the seller.
How do the five direct sale benefits affect the final comparison?
They adjust the home side downward and the land side not at all, which is why so many comparisons end with land ahead. Privacy: a direct sale has zero showings, zero open houses and no public marketing period, with no public record until the deed transfers. Flexible closing: the seller can settle in as little as a week, up to 21 days, or wait months with a leaseback arranged, instead of enduring the 60 to 120-plus days a listed older island home typically requires. No commissions: the typical 5 to 6 percent (National Association of Realtors, 2025) is $27,500 to $33,000 on a $550,000 sale, none of it charged directly. No seller closing costs: the usual 1 to 2 percent is not charged, and the two blocks together run 6 to 8 percent, or $33,000 to $44,000 on that example. No inspections or repairs: no $10,000 to $25,000 repair credits, because a land buyer performs no structural inspection.
In plain terms, a property is worth more as land when its residual land value, collectible in full on a short clock, exceeds what the home would net after the listed route has taken its documented share. That is a calculation any owner can run from the figures in this report.
What mistakes most often corrupt the comparison?
The first is comparing a gross number with a net number. An asking price, an estimate or a neighbor gross sale figure placed beside a direct bid will almost always flatter the home side, because none of the listed route costs have been taken out of it yet. The research ledger exists to prevent exactly that error: commissions, closing costs, repair credits and carrying costs come off the home side before any honest comparison begins (Frontier Capitals, 2026).
The second mistake is borrowing the wrong finished prices. Using beachfront finished sales to run the residual for a mid-island lot inflates the land side just as surely as using an island wide estimate inflates the home side. Segments price separately on this island, and the recorded sales for the correct segment are the only defensible inputs (Redfin, 2026). A related error is trusting an automated estimate that has absorbed nearby new construction prices into an older home valuation, a distortion the deed record exposes quickly (Zillow, 2026; Glynn County Clerk of Superior Court, 2026).
The third mistake is pricing the house by what was spent on it. Renovation history feels like value to the person who paid for it, yet the documented illustration shows a $75,000 update returning less than its cost even to a live-in buyer, and nothing to a lot buyer (Frontier Capitals, 2026). Money spent is a sunk record, not a market input. The fourth mistake is ignoring the parcel file: owners who guess at dimensions, flood standing or easements are running the test on an imaginary lot, while the real lot sits documented in county records (Glynn County Board of Assessors, 2026; Glynn County Tax Assessor, 2026).
The fifth mistake is treating the answer as permanent. Finished prices move, construction costs move, and a house that is a strong live-in candidate today loses systems and condition every year it is held without investment. The comparison is a snapshot with a date on it. Owners who run it cleanly, from segment prices and parcel records, and rerun it when circumstances change, make the land or home decision on evidence each time rather than on a conclusion inherited from an earlier market.
Methodology and limitations
This report rests on the sample compiled for the St Simons Island research: 17 older homes built in 1980 or earlier in 31522, 9 acquired by builders, with finished prices, parcel data and flood context from the sources listed below (Frontier Capitals, 2026; Redfin, 2026). The residual illustration is labeled a simplified illustration in the source research and is used the same way here. It is a method, not an appraisal, and it does not produce a maximum price for any specific lot beyond the documented ranges.
No property was inspected, surveyed or appraised for this report, and no universal ratio decides individual cases. The live-in exception is real, elevation can reverse an expected result in either direction, and the only determination the research supports for a specific property is the comparison itself, run with that property segment prices, its parcel record and at least one verified bid.
Conclusion
An owner determines whether a St Simons Island property is worth more as land by comparing two honest numbers: the residual land value built from segment finished prices, construction costs, margin and site preparation, and the net home value after the listed route takes its documented costs. With older homes averaging 23.1 percent of new build prices and builders taking 9 of 17 sampled homes, the land number wins that comparison across much of the island older stock (Frontier Capitals, 2026). Owners who want the comparison run on a specific property, with its parcel record read the way a builder reads it, can telephone Frontier Capitals at 401-219-4207 or email [email protected].

Frequently Asked Questions
What is the quickest first test of land value?
Run the residual from the nearest finished sales in your segment: finished price, minus roughly $620,000 of construction costs and a margin near 20 percent in the illustration, leaves land value near $550,000 to $650,000 on a $1,500,000 sale (Frontier Capitals, 2026). Then compare that range with a realistic net for the house as a home.
Can a small lot still be worth more as land?
Yes. Builder acquisitions in the sample reach down to a 6,098 square foot lot (Frontier Capitals, 2026). What matters is the buildable envelope and the segment finished price, both checkable in parcel records (Glynn County Board of Assessors, 2026).
Does renovating before the test change the answer?
Rarely in the owner favor. The documented $75,000 update returns $50,000 to $65,000 for a live-in buyer and nothing for a lot buyer (Frontier Capitals, 2026), so spending first usually moves the home value up by less than it costs, while the land value does not move at all.
How reliable is an online estimate for this decision?
Not reliable enough on its own. Estimates blend nearby sales that can include new construction, while recorded deeds separate older home results from finished home results (Zillow, 2026; Glynn County Clerk of Superior Court, 2026). Use the estimate as a glance and the record as the evidence.
What settles the question beyond argument?
A verified direct bid. Proof of funds dated within the last 30 days and recorded deeds in the buying entity name turn a land valuation from a calculation into an executable price (Glynn County Clerk of Superior Court, 2026).
