Glencoe Home Lists for $6.95 Million, Nearing $7.3 Million Off-Lakefront Record

Q: Why is a prominent lawyer suddenly selling his new luxury home for a near-record price?

There is no public evidence yet explaining why Louis Cairo is selling the Glencoe home now. What is clear is that the timing lines up with a strong luxury market. Cairo and his wife bought the 10,000-square-foot house at 677 Sheridan Road for $3.7 million in 2020 and have now listed it for $6.95 million, close to Glencoe’s off-lakefront record. The home is relatively new, built in 2019, and is being marketed on its high-end construction, design and amenities. In Glencoe, low inventory and continued demand for modern, move-in-ready luxury homes have supported aggressive pricing, even if buyers at the very top of the market remain selective. The asking price is also being tested against recent comparable sales. A non-lakefront spec mansion at 219 Lincoln Drive sold for $7.3 million in 2025, and a nearby lakefront mansion sold for $7 million that same year. Those deals give the sellers and their agent a basis to aim high, even though the Cook County assessor’s 2026 market value estimate for the property is much lower, at $4.33 million. That gap has fueled talk of speculative pricing along Sheridan Road, so the listing may reflect an effort to capitalize on peak market conditions as much as any personal reason. But absent a statement from the Cairos, any explanation beyond that would be speculation. At this point, the motive for the sale remains undisclosed.

Q: Is a home priced $2.6M over its official valuation a wise investment or a sign of a speculative market bubble?

It looks more like an aggressively priced luxury listing than clear proof of a bubble, but it is a high-risk buy unless the property’s unique features truly justify the premium. The $6.95 million ask is about $2.62 million above the Cook County assessor’s estimated 2026 market value of $4.33 million. That gap is notable, but assessor values are not the same as a live market appraisal and often lag fast-moving luxury markets. In Glencoe, recent evidence supports unusually high pricing: a non-lakefront spec mansion sold for $7.3 million in 2025, and the local luxury market has been marked by low inventory, strong demand, and sale-to-list ratios above 100% in parts of the market. That said, the upper end is more selective than the broader luxury segment. Buyers at this level are paying for scarcity, design, condition, and location, not just square footage. The Sheridan Road home is new, large, close to the beach, and marketed as turnkey, all of which matter. But the same reporting also points to speculative pricing allegations along Sheridan Road and warns that overpriced high-end homes can sit, lose momentum, and require cuts. So the investment case depends on the buyer’s goal. For an end-user who highly values this exact home and plans to hold it long term, the premium may be defensible. For a buyer focused on near-term appreciation or resale, paying far above assessed value in a thin, prestige-driven segment looks more speculative than prudent.

$6.95 million is the asking price for a six-bedroom Glencoe house at 677 Sheridan Road, putting the 2019-built property close to the suburb's off-lakefront pricing record.
10,000 square feet and nine bathrooms help explain the listing's premium, with the home sitting two blocks from Glencoe Beach on Sheridan Road.
The current owners, Louis and Gloria Cairo, bought the property for $3.7 million in March 2020, while the Cook County assessor valued it at $4.33 million for 2026.
That gap comes after assessment values along Sheridan Road from Wilmette to Glencoe jumped last year, fueling allegations that pricing on the corridor had turned speculative.
Glencoe's benchmark for a standard non-lakefront home remains a $7.3 million sale last year, while a nearby lakefront mansion sold for $7 million in April 2025.
