Penthouse 19: A full-floor Upper West Side penthouse at Linden 78, 230 West 78th Street
Full-floor penthouses with private terraces rarely come to market on the Upper West Side, and when one does, the way it launches shapes how it sells. For Penthouse 19 at 230 West 78th Street, the mandate was clear from day one: put this home in front of every serious buyer in the market.
We tested the price privately, launched publicly with a sharper price, and ran a campaign that reached buyers, their agents, and social media audiences simultaneously. In July 2026, Penthouse 19 closed for $7,075,000 to a buyer who already called the Upper West Side home.
The residence
An entire floor above the Upper West Side, with light on four sides and a terrace that looks across Central Park to Billionaires' Row.
Penthouse 19 sits on the 19th floor of Linden 78, a boutique, full-service condominium of just 34 residences built in 2008. With 3,129 square feet inside, three bedrooms, four baths, four open exposures and a 611-square-foot private terrace, it offers the kind of indoor-outdoor living that is genuinely hard to find in an Upper West Side condominium.

- A keyed private elevator opens directly into the home, onto a generous gallery made for displaying art.
- Living room
- North-facing, with floor-to-ceiling windows and a gas fireplace, it stays bright from morning to evening.

- Location
- Close to Central Park, Riverside Park and the American Museum of Natural History, with the 1, 2 and 3 trains moments away.
The brief
My client's priority was exposure: they wanted the home seen by as many qualified buyers and agents as possible before accepting an offer.
Three things made that more demanding than it sounds.
- A one-of-one home.Few full-floor terrace penthouses trade on the Upper West Side, so there were few direct comparables to anchor the price. In that situation, the first public number sets the tone for the entire campaign.
- A home ready for its next owner's touch.The residence needed some updating, and buyers at this level price the cost and time of renovation into their offers.
- A winter launch.Going public in November meant marketing through the holiday season, traditionally a quieter stretch for Manhattan sales.
The strategy
Learn from the market privately, launch with conviction, then reach every audience that could produce a buyer.
Test before going public
I first offered Penthouse 19 as a Compass Private Exclusive at $8,500,000 for one month. Sharing it quietly with Compass agents and their clients let us measure real demand without creating public price history or days on market.
Lead with the right number
What we learned privately shaped the launch. We went public at $7,995,000, just under $8 million, so the home entered the market positioned to compete and stayed visible to buyers whose searches top out at that mark.
Reach three audiences at once
Buyers directly, through private appointments. The agents who represent them, through broker events. And a wider audience online, through influencers who built engagement on social media.
The campaign
The response was strong and sustained. Through private appointments and broker events, Penthouse 19 welcomed more than 60 private viewings before going to contract, while influencers kept it in front of a wider audience online.
That level of traffic gave my client exactly what they asked for: confidence that the market had seen the home, and a clear picture of how buyers valued it.

The result

The buyer already lived on the Upper West Side, a reminder that the best buyer for a neighborhood standout is often right down the street. The final price came in about 11.5% below the last asking price, reflecting the updating the home needed. Buyers at this level budget for renovation, and we negotiated with that reality in view.
Most important, my client got what they asked for: a home that was fully and visibly marketed, privately and publicly, before they accepted an offer.

For penthouse sellers
Test before you go public
A Compass Private Exclusive lets you gauge demand at your number without building public price history you can't erase.
Price to lead, not to chase
Penthouse 19 carried about $11,190 a month in common charges and taxes alone. Every month on the market has a real cost, so the launch price matters.
Exposure is a strategy
Private appointments, broker events and online influencer engagement each reach a different audience. Use all three.
Condition is always priced in
Decide before listing whether to refresh, renovate or price for the work. Buyers will do the math either way.

Should I renovate my apartment before selling?
It depends on the home and the numbers. Buyers adjust their offers for the work a home needs, and Penthouse 19's final price, about 11.5% below the last ask, reflected the updating it needed.

How do influencers and broker events help sell a luxury home?
Influencers build online engagement, keeping a home in front of a wider audience on social media, while broker events put it in front of the agents who represent active buyers.
