Commercial Real Estate Brokerages, Tested by Where Their Space Comes From
One honest way to sort the top commercial real estate brokerages is to ask where their space comes from. A shortlist should draw on three sources: direct floors that are publicly listed, subleases and lease takeovers from companies handing space back, and floors a landlord has not started marketing. A brokerage that works only the first shows you what any website shows. For a startup or growth-stage team looking for value, the other two matter most, since that space often changes hands before it is advertised. Ask each firm how it hears about it, then read its shortlist for where it looked.

Three sources a value-minded team's shortlist should draw on
- Listed direct floors. The visible market: space a landlord is advertising, leased straight from the owner. It is the easiest to find and the most compared.
- Subleases and lease takeovers. Floors from companies that shrank, moved or were acquired. They are often already built and furnished, and the term is whatever remains on the original lease. The sublease playbook covers what to check.
- Floors not yet marketed. A landlord often knows a tenant is leaving months before a listing appears. Brokers who talk to that landlord regularly hear about it first.
No source is better in itself. A shortlist built from all three simply has more ways to hit your number.
Two inventory questions to put to every brokerage
- How do you hear about subleases and unlisted floors? A real answer describes relationships: the landlords and brokers the firm speaks to, and how often. A thin answer names a listings database.
- How many of your recent tenant deals came from that kind of space? Ask for a count and one or two examples, with client names removed if need be.
Be wary of the opposite failure as well. Unlisted space is not always there to be found, and nobody can promise it. A brokerage that sells itself on secret inventory is making a claim you cannot check until it is too late.
Reading a shortlist for where the brokerage really looked
The list a firm sends is a record of its search. Four patterns are worth a question.
- One landlord dominates. It may be a coincidence of your brief, or the firm may be close to that owner.
- Every floor is the firm's own listing. Then you are looking at its book, not at the market.
- No sublease appears. For a team seeking value, that usually means nobody checked.
- Asking rents are missing. A shortlist without prices cannot be compared and should be sent back.
Each has an innocent explanation. A firm that gives it without bristling has passed.
What Nomad's own book is, and where a search goes beyond it
Our book is a curated set of Manhattan floors, each published with its address, its size and, wherever the landlord has released one, its asking rent. Every available floor is on one page. It is not the whole city, and we do not present it that way.
A search we run for you starts from your brief and goes past our book, to other firms' listings, to subleases and to landlords we know. On your search, we work for you. Nomad also offers agency leasing and owner representation. If a floor on your list is one we lease for its owner, one firm would be on both sides, which in New York takes informed consent from you and from the owner. Ask us which floors that covers.
The floors below are our Chelsea listings. Chelsea is the value end of the Midtown South corridor: garment-era loft buildings west of Sixth Avenue, with the 1 train and the A/C/E and F/M lines close by. The Chelsea guide walks the blocks.

Does a brokerage with many listings of its own find better space for tenants?
Not automatically. Its own listings show that the firm works for owners in those buildings, which brings real knowledge of them and a possible conflict when a tenant client wants the same floor. Judge the firm on how far its shortlist reaches beyond its own inventory.
Can any brokerage promise access to space that is not on the market?
No. A firm can describe how it hears about such space and how often past searches turned some up. Whether any exists at your size, in your neighborhood, in the month you are looking is not something anyone controls.
Why would a shortlist leave out subleases altogether?
Sometimes none fits. More often the firm searched direct listings and stopped, or prefers direct deals. In most transactions the landlord pays the broker fee, while in a sublease the company giving up the space usually pays, so ask whether pay played any part.
Are the Chelsea floors on this page everything available in the neighborhood?
No. They are the floors Nomad lists there, with what each one asks. A search for you would also cover other firms' listings and subleases in the same blocks, so treat the block as a starting sample and not as the market.
