The preliminary range the calculator returned is a starting point. It accounts for market position, elevation, and square footage. It does not account for the heated Calacatta marble beneath our feet, the Lutron system that has been integrated with the HVAC, or the terrace that wraps three sides and adds 1,400 square feet of legally leasable air.
Those details require the walkthrough. Our clients are divorce attorneys splitting nine-figure estates, hedge fund principals quietly unwinding trophy positions before market shifts, and developers who need a certified number before the amenity floor has cured.
In each case, the accuracy of the appraisal is not an abstraction. It is the number that appears in court filings, in insurance riders, in offering memoranda. It is the number that holds.
When a hedge fund principal completed a full Gaggenau kitchen installation — refrigeration columns, steam oven, teppanyaki surface — the original appraisal was rendered obsolete. Our walkthrough identified $4.2M in attributable value the prior appraiser had missed: the Gaggenau system, a reconfigured butler's pantry, and the elimination of a structural column that opened the kitchen sightline to the terrace.
Final certified value: $46.8M. The reappraisal supported an insurance rider renegotiation that recovered $280,000 in annual premium.

At the 60th floor, every sightline is finite. Central Park's 843 acres represent a permanent void in the Manhattan grid — developable land that will never be developed. A direct north-facing park sightline at elevation 620 feet commands a 15–22% premium over an equivalent Hudson River view at the same floor, because the river view carries latent risk: Jersey City continues to build.
We weight sightline permanence, angular field of view, and historical comp divergence. A park-facing corner unit on the 64th floor of a Billionaires' Row tower carries a different multiplier than a park-adjacent unit on the 40th floor of a pre-war.

A developer needed a certified pre-sale valuation for the top four floors of a new Midtown tower while the amenity floor was still concrete. Our methodology accounts for projected amenity premiums using comparable towers' post-completion comp data, adjusted for the specific program: indoor pool, private dining, and a dedicated sommelier service that we valued at $1.1M in attributable per-unit premium across the crown units.
The pre-sale certification supported a $67M ask. The unit sold at $64.5M — within our predicted range — six weeks after the amenity floor opened.

A Lutron Homeworks QS system — properly installed, with scene programming for four zones and motorized shading throughout — adds differently than a Crestron OS3 integration with HVAC, AV, and security. Lutron is an amenity; Crestron is infrastructure. We have appraised both in over 340 properties and maintain a proprietary database of smart-system attributable value by building vintage, unit tier, and buyer profile.
In a 2025 estate settlement on Central Park South, the distinction between a Lutron-only system and a full Crestron integration was the difference between a $180,000 and $620,000 systems valuation — a $440,000 swing on a single line item.

In thirty years of handling high-net-worth divorce proceedings, I've retained six different appraisal firms. Appraise is the only one whose certifications have never been successfully challenged in court. When opposing counsel sees their signature, they stop arguing about the number.

We needed a pre-sale certification on four crown units before the amenity floor was finished. Every other firm wanted to wait. Appraise walked the raw space, consulted our architect, and delivered a range that the eventual sales prices landed inside. That's the whole game.

The fund was quietly unwinding a position in three Tribeca penthouses. We needed valuations that wouldn't move the market. Appraise understood the confidentiality requirements before I finished the sentence. Discreet, precise, and faster than I expected at this level.
