By Aidan Sowa · October 2026 · St Simons Island, GeorgiaThere is no documented standard percentage that cash buyers pay on St Simons Island, and any buyer who quotes one as an island rule is inventing it. What the island record does document is a method. A cash buyer who intends to place a property with a builder starts from what a finished new home can sell for, subtracts construction cost and a builder margin, and treats what remains as the value of the land. The worked illustration in the island research runs that arithmetic on a $1,500,000 new build sale: roughly $620,000 in hard and soft construction costs and a builder margin near 20 percent leave a residual land value near $550,000 to $650,000, before $20,000 to $35,000 in site preparation costs (Frontier Capitals, 2026). An offer for an older house on a comparable lot is built inside that residual, not pulled from a percentage table.
The sample behind the illustration shows why the land carries the price. The study compiled for this report covered 17 older homes in 31522, with 9 acquired by builders and a builder demand rate of 52.9 percent (Frontier Capitals, 2026). The average older home sold for 23.1 percent of the price of new construction on a comparable lot, so where a new build sold for $1,400,000, the older home on a similar lot changed hands for roughly $325,000. On ordinary lots, recent new builds have changed hands between $1.1 million and $1.9 million, with the exact figure tracking how close the lot sits to the beach or marsh and how much land it holds (Redfin, 2026). Read together, those figures describe a market where over three quarters of the finished value sits in the ground, and where a cash offer is therefore a land bid with a house attached, whether the seller thinks of it that way or not.
That framing changes how a seller should judge any number presented. The practical steps behind how to sell a house for cash in St Simons Island matter less than the arithmetic test an offer should pass: can the buyer show the new build comparable, the construction estimate and the margin that produced the figure. An offer that survives those questions is grounded. An offer that arrives as a round fraction of an asking price, with no lot level reasoning behind it, is not grounded in anything this island market documents.
Key Findings
- No cash buyer offer percentage or discount percentage is documented in the island materials, so this report answers by the documented residual method instead (Frontier Capitals, 2026).
- The worked residual illustration leaves land value near $550,000 to $650,000 on a $1,500,000 new build sale, after roughly $620,000 in construction costs and a margin near 20 percent, before $20,000 to $35,000 in site preparation (Frontier Capitals, 2026).
- The sample of 17 older homes recorded 9 builder acquisitions, and the average older home price was 23.1 percent of new build price on a comparable lot (Frontier Capitals, 2026).
- New construction on standard lots has sold in the $1.1 million to $1.9 million range, varying with beach or marsh proximity and lot size (Redfin, 2026).
- Location on the island moves the residual first, ahead of lot size and buildable footprint and then elevation and flood compliance (Frontier Capitals, 2026).
Where does a cash offer number actually come from?
It comes from the finished house the lot can support, worked backwards. A builder oriented buyer asks what a new home on that homesite would sell for, using recorded island sales of new construction rather than hopes (Redfin, 2026). From that sale price the buyer removes the cost of building the house, roughly $620,000 in the documented illustration covering hard and soft costs, and removes a margin near 20 percent that compensates the builder for capital, time and market risk. What is left is the most the land can be worth to that project. Site preparation, documented at $20,000 to $35,000, comes out of the same residual in practice, which is why two lots with identical new build prospects can still draw different offers when one needs more preparation than the other.
Each input in that chain can be checked by a seller. New build sale prices sit in sold records (Redfin, 2026). Parcel dimensions, lot configuration and permit history sit in county records (Glynn County Tax Assessor, 2026). Flood zone designations and parcel dimensions that shape the buildable footprint are also held in assessor records (Glynn County Board of Assessors, 2026). A seller who asks a cash buyer to walk through the comparable sale, the cost figure and the margin is not being difficult. That seller is asking the buyer to show the only documented basis an island cash offer has.
The 23.1 percent average ratio gives sellers a second, rougher check (Frontier Capitals, 2026). It is an average across the sampled older homes, not a pricing rule for any single address, and it blends lots across the Village, mid-island and the Beachfront Blocks. A well positioned lot near the beach should sit above what the bare average implies, because new build prices near the beach sit at the top of the documented $1.1 million to $1.9 million range (Redfin, 2026). An interior lot with a constrained footprint should sit below it. The ratio tells a seller whether an offer is in a plausible neighborhood. The residual walk through tells the seller whether it is fair for that lot.
Why do offers differ so much from lot to lot?
Because the residual differs, and location drives the difference first. Beachfront and marsh view premiums show up clearly in new build sale prices, while older home listings rarely capture them, so a lot in the Marsh-View Corridors or the Beachfront Blocks supports a higher finished price and therefore a higher land residual than a similar sized interior lot (Frontier Capitals, 2026). The same premium logic explains much of what homes are actually selling for in St Simons Island, where finished values separate sharply by position on the island even when the houses standing on the lots look alike.
Next in importance is the amount of ground a parcel offers and the share of it a builder can actually use. The sample minimum lot was 6,098 square feet, and flood zone setbacks constrain the envelope a builder can actually use (Frontier Capitals, 2026). A large lot that loses much of its area to setbacks may support no more house than a smaller, cleaner lot, and offers follow the buildable area rather than the surveyed area. Building permit and tree protection requirements also shape what can be placed on a lot, since the live oak canopy is part of what builders price around (Glynn County Community Development, 2026). A mature oak in the middle of the only sensible building envelope is a pricing fact, not a landscaping detail.
Elevation and flood compliance come third, and on a barrier island they can override the first two. Flood pricing follows the National Flood Insurance Program Risk Rating 2.0 methodology, and elevation certificate requirements shape both insurance cost and building obligations (Federal Emergency Management Agency, 2026). A low lot that requires an elevated foundation costs the project more to build on, and that extra cost comes out of the same residual the offer is drawn from. County flood maps and permit records let a seller see the designation attached to a parcel before negotiations begin (Glynn County Board of Assessors, 2026). None of this variation is evidence of a buyer acting in bad faith. It is the documented arithmetic responding to documented differences between lots.
How should a seller judge an offer against the listed alternative?
By comparing net outcomes rather than headline numbers, and by remembering what the listed route charges. On a $550,000 sale, commission typically runs 5 to 6 percent, or $27,500 to $33,000 (National Association of Realtors, 2025), and the average buyer agent commission alone was 2.4 percent for homes sold in the first quarter of 2025 (Redfin, 2025). Seller closing costs add another 1 to 2 percent, concessions and inspection repair credits on older island inventory routinely run $10,000 to $25,000, and carrying costs over three to six months run $15,000 to $35,000 (Frontier Capitals, 2026). An asking price is therefore not a proceeds figure. The fuller profitability comparison is worked through in whether selling to a builder beats selling to a homebuyer on this island, and sellers who skip that netting step routinely overvalue the listed route by five figures.
Online estimates deserve the same skepticism in both directions. Valuation tools track recorded sales and listing data (Zillow, 2026), but an automated estimate cannot see a buildable footprint, an elevation certificate or the oak canopy over a specific lot, and on this island those unseen items are exactly what moves a builder bid. An estimate can be a starting point for conversation. It cannot substitute for the residual walk through, and a cash offer below an automated estimate is not automatically a low offer, just as one above it is not automatically generous.
Time on market carries its own quiet discount. The analysis of why some island houses sit on the market without selling shows how a stale listing invites the reductions and credits that the documented ledger predicts. House price movement across coastal Georgia provides wider context for how finished values drift over a long holding period (Federal Housing Finance Agency, 2026), but a seller holding a property for months is paying island insurance, taxes and maintenance in the meantime. A cash offer accepted promptly should be credited with the carrying months it removes, valued inside the documented $15,000 to $35,000 range, before it is compared with a hypothetical listing outcome.
What does Frontier Capitals offer when it buys directly?
Frontier Capitals is a wholesaler. It buys directly from sellers and sources off market deals to builders, and it never presents itself as a builder. Its offers are built from the same residual logic described throughout this report, checked against the specific lot, its flood position and its buildable footprint. The five benefits attached to a direct purchase are concrete at island price points. Privacy comes first: zero showings, zero open houses, no public marketing period and no public record until the deed transfers, which matters on a small island where a listing announces a household decision to every neighbor.
Flexible closing comes second: 7 to 21 days when speed matters, or months out with a leaseback when a seller needs time to relocate, against 60 to 120 plus days for a listed older island home. No commissions comes third: the typical 5 to 6 percent, $27,500 to $33,000 on the $550,000 example, is not charged (National Association of Realtors, 2025). No seller closing costs comes fourth: the typical 1 to 2 percent is not charged either, so commissions and closing costs together, 6 to 8 percent or $33,000 to $44,000 on that example, stay with the seller. No inspections or repairs comes fifth: the house sells as is, with no $10,000 to $25,000 repair credits, because the end buyer is purchasing the land and performs no structural inspection.
Sellers deciding how to invite a grounded number will find the practical sequence in how to get a cash offer for a house in St Simons Island, and sellers holding more than one bid can use how to compare multiple cash offers on an island house to test each figure against the residual rather than against the other bids alone. Verification belongs in that comparison: proof of funds in the buyer name dated within the last 30 days, and recorded deeds in the buyer entity name from actually closed purchases, checkable in county records (Glynn County Tax Assessor, 2026). A buyer who can show both, and who can explain the arithmetic, is offering a number with a basis.
Methodology and limitations
This report draws its offer discussion from the sample compiled for the island research: 17 older homes in 31522 built in 1980 or earlier, 9 acquired by builders, the 23.1 percent average price ratio, and the worked residual illustration built on a $1,500,000 new build sale (Frontier Capitals, 2026). New build and sold price context comes from island listing and sold records (Redfin, 2026) and valuation data (Zillow, 2026). Commission context comes from national association data (National Association of Realtors, 2025) and post settlement commission analysis (Redfin, 2025). Parcel, flood and permit facts rest on county records (Glynn County Tax Assessor, 2026; Glynn County Board of Assessors, 2026; Glynn County Community Development, 2026).
The central limitation must be stated without softening: the materials document no cash buyer offer percentage, no discount percentage and no formula that converts an asking price or an estimate into a typical offer. The residual illustration is labeled in the research as a simplified illustration and not a promise, and individual offers move with the finished value a specific lot can support, its buildable footprint and its flood compliance costs. A seller should treat any percentage quoted by any buyer as that buyer marketing, not as an island statistic, and should ask for the lot level arithmetic instead.
Conclusion
Cash buyers on St Simons Island typically offer what the land can support after construction cost and margin are removed from a realistic new build sale price, illustrated at $550,000 to $650,000 of residual land value on a $1,500,000 sale before site preparation (Frontier Capitals, 2026). The 23.1 percent average ratio between older home prices and new build prices confirms that the structure contributes little to that figure on the sampled homes. No documented percentage exists, and the honest way to evaluate an offer is to audit its inputs: the comparable finished sale, the cost figure, the margin and the adjustments for footprint, elevation and trees.

If two cash offers differ by tens of thousands of dollars on the same lot, which buyer inputs would you ask to see first before deciding which number to trust?
Frequently Asked Questions
Is there a standard percentage cash buyers pay on the island?
No. The island materials document no offer percentage and no discount percentage for cash buyers. Offers are built by the residual method, illustrated at $550,000 to $650,000 of land value on a $1,500,000 new build sale (Frontier Capitals, 2026), and they vary by lot.
Why is an offer so much lower than what a new home nearby sold for?
Because the finished sale price must also pay for construction and margin before anything reaches the land. The documented illustration removes roughly $620,000 in construction costs and a margin near 20 percent from a $1,500,000 sale (Frontier Capitals, 2026). The older home average of 23.1 percent of new build price reflects that same split across the sample.
Does a bigger lot always draw a bigger offer?
No. Offers follow buildable footprint, not surveyed size alone. The sample minimum lot was 6,098 square feet, and flood zone setbacks constrain the usable envelope (Frontier Capitals, 2026). Parcel and flood records show the designations that shape a specific lot (Glynn County Board of Assessors, 2026).
How can a seller check whether an offer is grounded?
Ask for the comparable new build sale, the construction cost figure and the margin, then verify the lot facts independently. Sold records document finished prices (Redfin, 2026), and county records document parcel dimensions and permit history (Glynn County Tax Assessor, 2026). A grounded buyer can show each input without hesitation.
Will renovating before seeking a cash offer raise the number?
Usually not for a builder oriented buyer. The documented renovation illustration shows a $75,000 update returning $0 where the buyer clears the lot, because the purchase prices the land (Frontier Capitals, 2026). A genuinely livable, well kept home is the honest exception, since it can attract a live in buyer premium through a listing instead.
