By Aidan Sowa · October 2026 · Elmhurst, IllinoisFor the older stock in Elmhurst, the evidence points that way. Within the group tracked here, builders took 10 of 12 older homes, while the typical older home traded at just 26.6 percent of what new construction fetched on a similar lot (Frontier Capitals, 2026). The simplified residual illustration in the research goes further: on a $1,500,000 new build sale, after roughly $600,000 in construction costs and a margin near 20 percent, the residual land value sits around $575,000 to $650,000 before site preparation (Frontier Capitals, 2026). Set that beside the roughly $400,000 the sampled older homes changed hands for at the documented ratio, and the meaning is plain. The ground under a large Elmhurst lot can support more value than the older home standing on it has been trading for.
Becoming is the right word, and this post keeps it. No figure in the materials says every large lot is now worth more than every older home, and a renovated home near downtown Elmhurst can still command a household premium above builder pricing (Frontier Capitals, 2026). The direction, though, is documented from several sides at once: builders taking 83.3 percent of the sampled older homes, finished homes selling from $1,300,000 to $1,700,000 on standard lots, and a sample that begins at a minimum lot of 7,365 square feet on ground that typically runs about a quarter acre (Frontier Capitals, 2026; Redfin, 2026). Owners who want the lot size effect isolated can start with the study of how much lot size affects property values in Elmhurst.
Key Findings
- Builders acquired 10 of 12 older homes in the sample, at an average price of 26.6 percent of new build price on comparable lots (Frontier Capitals, 2026).
- The simplified residual land value on a $1,500,000 finished sale is $575,000 to $650,000 before $20,000 to $35,000 in site preparation (Frontier Capitals, 2026).
- The sampled older homes changed hands near $400,000 in the worked example, below the residual ceiling the same ground can support (Frontier Capitals, 2026).
- Standard Elmhurst lots run about a quarter acre, the sample minimum lot was 7,365 square feet, and Elmhurst ranked 78th of 189 in the study (Frontier Capitals, 2026).
- New construction sold from $1,050,000 to $1,900,000 overall and from $1,300,000 to $1,700,000 on standard lots (Redfin, 2026).
- The citywide median was $697,500 in September 2026, with 26.7 percent of sales paid in cash (Realty.com, 2026).
Why is the gap between lot value and house value widening in Elmhurst?
The finished product is pulling away from the existing stock. New homes in Elmhurst sold up to $1,900,000, and the builder acquisition trade operates at roughly double the citywide median, per the research summary (Redfin, 2026; Frontier Capitals, 2026). An older ranch or split level from the 1950s to 1970s, the typical stock on these lots, is priced by a household buyer against other older homes. The same lot is priced by a builder against a finished sale of $1,300,000 to $1,700,000 (Redfin, 2026). Those two pricing systems do not move together. When finished prices rise faster than household prices for dated homes, the lot share of total property value rises with them, and a large lot, which can carry a larger finished home, feels that rise most strongly.
Supply does the rest. Elmhurst is a built out village of roughly 46,000 residents in DuPage County (U.S. Census Bureau, 2025). New village lots are not being created at any scale, so a builder who wants to sell a new home in Elmhurst must buy the ground from under an existing older home. That is the structural fact behind the sample result: 10 of 12 older homes went to builders (Frontier Capitals, 2026). National building activity, with single family starts at 918,000 at a seasonally adjusted annual rate in August 2026, shows builders nationally still need lots to build on (National Association of Home Builders, 2026). In a built out village, that need lands on the owners of large older lots.
Carrying the ground is also expensive in Illinois, which cuts both ways and deserves a mention. A 50 state comparison put the Illinois effective property tax rate at 1.88 percent, ranked 2nd, against about 0.85 percent nationally (Tax Foundation, 2026). High carrying costs discourage holding a large lot idle for years in hope of a better price, and they push some owners of older homes toward a decision. They also form part of the cost a builder counts before paying for land, which is one reason actual purchase prices sit below the theoretical residual rather than at it.
How large does a lot have to be before the ground leads the value?
The sample gives a floor, not a threshold formula. The minimum lot among the sampled homes was 7,365 square feet (Frontier Capitals, 2026). Standard lots run about a quarter acre, which is larger than that minimum, so much of the ordinary Elmhurst stock already sits in the size band builders were buying in the sample. Size alone is not the trigger, though. The recorded facts for a specific parcel are parcel dimensions, zoning classification, and assessed land value (DuPage County Assessor, 2026). A wide lot and a narrow lot of equal area are not equal to a builder, because the finished home has to fit the shape as recorded, and the second county record set, covering lot dimensions, zoning classification, and assessed values, lets an owner cross check the shape and classification before drawing conclusions (DuPage County Supervisor of Assessments, 2026).
Position multiplies size. Streets in the York District and homes near downtown Elmhurst carry premiums that show up in new build comparisons but rarely in older home listings (Frontier Capitals, 2026). A large lot in a premium position can support a finished sale at the top of the $1,300,000 to $1,700,000 standard lot range or above it, within the wider $1,050,000 to $1,900,000 band (Redfin, 2026). A large lot in the Salt Creek Corridor must be read with its floodplain position in view, since the research notes that position affects insurance and buyer math (Frontier Capitals, 2026). Large, premium, and dry is the strongest combination. Large alone is only the beginning of the calculation.
County records make this test available to any owner without hiring anyone. Parcel, permit, and assessment records for Elmhurst are held at county level (DuPage County, 2026). An owner can confirm the dimensions, look at the assessed split between land and building, and check whether replacement building has been permitted on comparable lots nearby. If the land assessment is a large share of the whole, if the lot is at or above the sample sizes, and if finished sales nearby sit in the documented range, the probability is high that the ground now leads the value. The builder side of the same test is quantified in the analysis of how much lot size affects what builders pay for Elmhurst properties.
When is the older home still worth more than its lot?
The exception is documented and should not be argued away. Near the downtown core, a 1960s ranch that has already been updated can fetch well above what a builder would pay to acquire the property (Frontier Capitals, 2026). In that case a household buyer is paying for the house, the renovation, and the position together, and the total can beat what the lot alone would draw. The renovation illustration shows the limit of that path, though: a $60,000 kitchen and bath update might lift the price by $40,000 to $50,000 with a buyer who intends to live in the home, and returns $0 with a buyer who intends to redevelop (Frontier Capitals, 2026). The home beats its lot when its condition and position are already strong, not usually after new spending meant to manufacture that result.
The citywide median offers a sanity check in both directions. Elmhurst median sale price was $697,500 in September 2026, and a county level update put the Elmhurst median at $697,039 in August 2026 (Realty.com, 2026). A good older home trading near that median is trading well above the $400,000 sample example, and its owner should test the household route seriously before assuming the lot leads. Conversely, an older home whose household market sits in the low $400,000s, on a lot at or above standard size near documented new build sales, is very likely a property whose ground is the asset. Both conclusions come from the same habit: price the house and the lot separately, then compare. Owners who want the lot figure on its own can use the study of how much a residential lot is worth in Elmhurst.
Time also separates the two values. A household sale of an older home more commonly takes 60 to 120 plus days from first showing to funded close, and 90 to 180 days including market time (Frontier Capitals, 2026). During that period the lot value does not wait politely. Builder pipelines fill, finished sale ranges shift, and the carrying costs on the property, $10,000 to $25,000 over three to six months on the research ledger, come out of the household route result (Frontier Capitals, 2026). An owner comparing a house price achieved after five months with a lot price available now is not comparing equal outcomes, even before commission enters the table.
What should an owner of a large Elmhurst lot do with this shift?
First, stop pricing the property from the house alone. Pull the parcel record and read the dimensions, classification, and assessed land value as a set (DuPage County Assessor, 2026; DuPage County Supervisor of Assessments, 2026). Then set the finished sale range for the street from recent sold and new construction records (Redfin, 2026), and run the simplified residual: finished price, minus roughly $600,000 in construction costs on the $1,500,000 illustration, minus a margin near 20 percent, leaving $575,000 to $650,000 before site preparation (Frontier Capitals, 2026). Treat that result as a ceiling that explains builder behaviour, not as an entitlement, and test any real offer against both it and the $400,000 sample example.
Second, compare routes on net. A listed sale at $400,000 pays commission of $20,000 to $24,000 at 5 to 6 percent (National Association of Realtors, 2025), plus seller closing costs of 1 to 2 percent, with commissions and closing costs together commonly exceeding $24,000 (Frontier Capitals, 2026). Frontier Capitals, which sources off-market deals to builders and buys with its own capital without claiming to be a builder, offers the contrasting structure. Privacy, with no showings, no open houses, and no public marketing of a large lot that neighbours would certainly notice. Timing can bend either way, settling in 7 to 21 days or waiting months while the seller stays on under a leaseback. No commission, preserving the $20,000 to $24,000 at the $400,000 level (National Association of Realtors, 2025). No seller closing costs, keeping the 1 to 2 percent. And a sale as it stands, with no inspections or repairs and no $10,000 to $30,000 credit discussion. For a property whose value is mainly ground, those terms fit the asset: the buyer is purchasing the lot, and the house on it needs no preparation to be priced.
Third, verify whoever quotes the lot value. A serious buyer shows proof of funds in the buyer name dated within the last 30 days, recorded deeds in the buyer entity name checkable in county records, and a meaningful earnest money deposit forfeited on a walk away (Frontier Capitals, 2026). An owner of a large lot is exactly the owner most likely to be approached with a large, soft number. The deed record and the parcel record are the two documents that turn that number into evidence. Owners ready to test the specific case can also read the report on whether larger lots in 60126 are worth more to builders than smaller lots.
Methodology and limitations
This post rests on the sample compiled for this report: 12 older Elmhurst homes, 10 acquired by builders, an average price of 26.6 percent of new build price, a minimum lot of 7,365 square feet, and a ranking of 78th of 189 (Frontier Capitals, 2026). Finished price ranges come from recent sold and new construction records (Redfin, 2026), the median and cash share from the September 2026 snapshot (Realty.com, 2026), and parcel facts from county assessor and supervisor of assessments records (DuPage County Assessor, 2026; DuPage County Supervisor of Assessments, 2026), with the general county record base behind them (DuPage County, 2026).
The limits are real. The sample is not a census of 60126, and no lot by lot price series over time is documented in the materials, so the word becoming describes a direction supported by the sample, the residual illustration, and the finished sale ranges, not a measured year by year index for large lots specifically. The residual figure is a simplified illustration and not a promise. Individual properties will depart from every average here, in both directions, for reasons of shape, position, floodplain status, and condition that only a parcel level review can weigh.
Conclusion
Large Elmhurst lots are becoming more valuable than the older homes on them in the cases this sample actually covers: older stock, standard to large lots, streets where finished homes sell from $1,300,000 to $1,700,000 (Frontier Capitals, 2026; Redfin, 2026). Builders took 10 of the 12 sampled homes, the residual land value on a $1,500,000 build reaches $575,000 to $650,000, and the sampled homes themselves changed hands near $400,000 (Frontier Capitals, 2026). That ordering, ground above house, is no longer an oddity in Elmhurst. It is the pattern an owner of a large lot should test first.
An owner who wants the test run on a specific parcel, with its recorded dimensions and its street finished sales in hand, can call Frontier Capitals at 401-219-4207 or write to [email protected] for a plain separation of what the house is worth and what the ground is worth.
When the ground under your home can support $575,000 to $650,000 of value and the home itself trades near $400,000, which of the two have you really been owning all these years?
Frequently Asked Questions
Are all Elmhurst lots now worth more than the homes on them?
No. The pattern covers the sampled older stock, where builders acquired 10 of 12 homes (Frontier Capitals, 2026). A renovated home near downtown can still sell above builder pricing, and newer or larger homes are a different case entirely (Frontier Capitals, 2026).
What lot size did the builder sample start at?
The minimum lot in the sample was 7,365 square feet, and standard Elmhurst lots run about a quarter acre (Frontier Capitals, 2026). Owners can confirm their own dimensions in the assessor parcel record (DuPage County Assessor, 2026).
Where does the $575,000 to $650,000 land figure come from?
It is the simplified residual illustration in the research: a $1,500,000 finished sale, minus roughly $600,000 in construction costs and a margin near 20 percent, before $20,000 to $35,000 in site preparation (Frontier Capitals, 2026). It is a ceiling under those assumptions, not an offer.
How does the Elmhurst median compare with the lot story?
The September 2026 median was $697,500 across all homes sold (Realty.com, 2026). That blend includes finished new construction, so it sits above the older home sample example of near $400,000 and below the top new build sales (Frontier Capitals, 2026; Redfin, 2026).
What records should a large lot owner check first?
Parcel dimensions, zoning classification, and assessed land value in the assessor records (DuPage County Assessor, 2026), cross checked against the supervisor of assessments parcel records (DuPage County Supervisor of Assessments, 2026), plus permit and assessment history in the general county record (DuPage County, 2026).
