Bill Pearch has lived on the 900 block of South Hillside Avenue for two decades. In March, he stood before the Elmhurst City Council and gave his street a different name: teardown alley. For more than 600 consecutive days, he told the council, his block has been an active construction zone. Heavy machines. Crews. Tree removals. A house that shakes when the equipment next door runs.
County records confirm his home's value has climbed too, now assessed at $420,000, up from $360,000 in 2021. But Pearch doesn't feel richer. He isn't selling, and he told the council exactly why that matters: "We only get increased property value when we sell." His taxes rise on paper equity he can't spend unless he moves.
That single sentence explains more about Elmhurst's real estate market right now than any citywide median. It's the friction point buyers and sellers on older blocks need to understand before they price a home, and it comes down to a piece of math most people never see explained: at some point on every block, the land underneath a house becomes worth more than the house itself. Once that happens, the rules for pricing that property change completely, whether the owner wants them to or not.
When the Land Outvalues the House
Pearch's own block shows the shift in plain numbers. Back in 2006, Hillside Avenue saw one teardown and four expansions. Owners who wanted more space built onto what they had. In the six years since, that pattern flipped entirely: zero expansions, ten teardowns, with two more expected. The houses on that block didn't change. What changed is which side of a value line the underlying lots landed on.
Here's the mechanism. When a builder looks at an older home, they aren't pricing the kitchen or the roof. They're pricing the dirt, minus what it costs to clear the existing structure, plus what a new home on that lot will sell for. On Hillside, new construction is running around $1.5 million. Once that math pencils out ahead of what a family buyer would pay for the existing house as-is, the existing house stops competing on its own condition. It competes on how fast someone can remove it.
That's why two houses three doors apart can sit in completely different markets. One owner is selling a home. The neighbor, without changing a thing, is really selling a lot that happens to have a house sitting on it.
The $2,416 Fee That Doesn't Slow Anything Down
The city has tried to put friction into that math. Elmhurst's residential permit fee schedule, in effect through this past spring, set the demolition permit at $2,416. Against a $1.5 million rebuild, that fee is a rounding error, not a deterrent. It shows up as a line item, not a decision point.
That's worth sitting with if you're an owner hoping city policy will slow redevelopment on your block before you sell. The fee structure isn't designed to change the underlying land economics, and nothing in the current schedule suggests it's meant to. It collects revenue on a transaction that was already going to happen.
A $2 Million Purchase for a Lot, Not a House
The clearest version of this math played out in 2024 on South Arlington Avenue, where a nearly century-old home changed hands for close to $2 million. The buyers weren't purchasing a century of character. They applied to merge the lot with a vacant parcel next door so they could build a larger home across both. Neighbors pushed back, citing the loss of a historic property, and the fight went to the Zoning and Planning Commission before the City Council approved the rezoning 12-1.
Two million dollars for a house destined for demolition only makes sense if you separate the price from the structure entirely. The buyers were pricing frontage, lot depth, and buildable square footage. The house itself was, in economic terms, incidental.
Why the City's Own Numbers Disagree
If you're trying to use citywide figures to price a single block, the numbers won't agree with each other, and that disagreement is itself informative.
Mayor Scott Levin's January 2026 State of the City address described average home sale prices rising nearly 50 percent over five years, alongside a genuine civic win: 67 new homes built in 2025, the most of any DuPage County municipality. Two months later, a Patch report on the Hillside Avenue teardowns put the average sale price at $761,000, up from $410,000 five years earlier, a jump closer to 86 percent. A Metropolitan Mayors Caucus housing study, released that same February, cited a median sale price of $604,000 for the prior year, up from $300,000 in 2012.
Three credible sources, three different growth stories, all describing the same city in the same season. None of them are wrong. They're measuring different things (averages versus medians, different five-year windows, different baseline years), which is exactly the point. A citywide number is a blend of every transaction type happening at once, including million-dollar rebuilds and untouched 1950s ranches three blocks away.
The same blending shows up in day-to-day portal data. A February 2026 snapshot placed Elmhurst's median sale price at $635,000, up 41 percent year over year. By July 2026, a different portal's monthly read put it at $689,900. A separate typical-value index, updated through July 2026 and measuring something else entirely, sat far lower, near $505,500. If you're pricing your specific house on your specific block, none of these numbers are describing you. They're describing an average of a market that includes both sides of the teardown line.
How to Read Your Own Block Before You Price It
Instead of starting with the citywide median, start with the block. A few concrete steps tell you which side of the line you're on:
- Count recent activity within two or three doors. Dumpsters, demolition permits, and construction fencing on a block are a faster signal than any market report. Pearch's own testimony is a case study in how fast that count can climb.
- Pull the parcel's land-to-total-value split from the county assessor's record. If the land value alone is closing in on what similar move-in-ready homes are selling for, you're closer to the teardown side than you might think.
- Compare recent "as-is" sales on the block to what actually got built there. If the buyers were builders rather than families, that's your market, whether or not you want it to be.
- Check lot dimensions against recent new construction nearby. Builders consistently pay more for wider, deeper lots, independent of the condition of whatever is currently built on them.
If the answers point toward redevelopment, marketing the home as a polished family property can actually leave money on the table. The buyer paying the highest price isn't shopping for a kitchen. If the answers point the other way, the math flips: a thoughtful rehab, a refreshed exterior, and a price built around comparable finished homes is exactly how you capture full value, because the buyer is paying for the house, not the dirt underneath it.
That's the same judgment call behind the affordability conversation playing out at City Hall. A state report cited in 2024 placed Elmhurst's affordable housing share at 9.4 percent, up only slightly from 9.3 percent a decade earlier, and the Metropolitan Mayors Caucus has since floated ideas like a community land trust to address it. That's a policy debate for elected officials to work through. For a homeowner deciding how to price and market one specific property, the more immediate question is simpler: has your block already crossed the line, and does your pricing strategy know it yet?
If you're trying to answer that for your own address, I'd rather run the numbers with you than have you guess from a citywide average. Reach out through Edgar R.
