Sell or Convert Your NYC Office Building?

The Fork in the Road

The 467-m abatement and a wave of office vacancy have turned hundreds of older Manhattan office buildings into viable residential conversion candidates. That optionality is valuable — but it forces a decision most owners are not equipped to make alone: do you take on the conversion yourself, or sell to someone who will?

Both paths can be right. Converting captures the full upside if you have the capital, the expertise, and the appetite for multi-year execution risk. Selling off-market to an experienced converter captures much of that upside today, in cash, with none of the construction, financing, or lease-up risk — and often at a basis the converter is happy to pay because the abatement makes the math work for them.

When Converting Yourself Makes Sense

Conversion is the right call for a specific kind of owner. If you check most of these boxes, keeping and converting the asset can capture the largest total return.

• You have — or can raise — the substantial construction and bridge capital a full conversion requires.
• You have residential development and lease-up expertise in-house, or a development partner who does.
• You can carry the asset through a multi-year design, approval, construction, and stabilization timeline.
• You are comfortable underwriting construction, interest-rate, and absorption risk over that horizon.
• The building's floorplate, light, and core genuinely suit residential layouts (not every office converts well).

When Selling Off-Market to a Converter Nets More

For many owners — especially those without a development arm, or who want certainty and liquidity now — selling to a converter is the higher-net, lower-risk outcome. The 467-m abatement raises what converters can pay, and an off-market process delivers that premium without exposing the building to the market.

• You want cash and certainty now rather than a multi-year return contingent on execution.
• You do not have residential conversion expertise or the capital stack to fund it.
• You want to avoid construction, financing, and lease-up risk entirely.
• The building is partially or fully vacant and bleeding carry — every month of indecision is a cost.
• Confidentiality matters: a quiet sale avoids signaling distress to lenders, tenants, and the market.

Sell vs. Convert — The Trade-Offs Side by Side

How the two paths compare across the variables that actually drive the decision. The right answer is specific to the asset and the owner — Skyline models both before advising.

Run the abatement math before you decide

The 467-m abatement materially changes both sides of this equation — it raises the residual value a converter can pay, and it raises the return on a conversion you fund yourself. Before committing to either path, run your building through Skyline's 467-m calculator to see the abatement's effect on a 35-year NPV basis.

Then get a confidential Broker Opinion of Value. Skyline will tell you what a converter would realistically pay off-market today, set that against a conversion pro forma, and give you the honest net-proceeds comparison — including the recommendation that selling is not the right move, when that is the truth.

The first step costs nothing

If you own a Manhattan office building and are weighing conversion against a sale, start with a confidential Broker Opinion of Value. Skyline will model both paths to a net-proceeds number — convert-yourself versus sell-to-converter — so you decide with real figures, not a hunch.

There is no cost, no obligation, and no exposure: Skyline will not market the building or signal a process until you decide to engage. Reach Robert Khodadadian directly at (212) 537-9239 or info@skylineprp.com.
