New York State, New York City / Manhattan office, store, retail, gallery and restaurant space...


Founded in 1988, Longstreet Associates is a proud member of The Real Estate Board of New York. We specialize in office and retail space leasing / for rent in prime Manhattan / New York City locations, in addition to the sales of buildings and development sites. 

As a small firm, Longstreet works with a few clients at a time, ensuring that each will be serviced with complete satisfaction. The New York City office space for rent market can be tricky, but you need not fear, as we can guide you through the leasing process. 

We have completed office space searches from 1,000 square feet to over 500,000 square feet, from Downtown Brooklyn and Brooklyn Heights to Flushing, Queens and throughout Manhattan and the rest of New York City--from the Battery to Wall Street, Tribeca, Soho, Flatiron, Chelsea, the Garment District, Times Square, Columbus Circle, the Grand Central District, The Plaza District, East and West Midtown to Harlem. 

Although we generally represent clients searching for Manhattan office space for rent, building and development site sales, and Manhattan stores for rent, we also work with landlords and tenants seeking to market space.

Longstreet has relationships with clients worldwide, and we have done direct searches and referral deals across the US and throughout Europe, Asia and the Middle East.  We pride ourselves on discreetly working with customers on their many different needs, such as finding an office and store for the same firm. Most of our development site and hotel availabilities are "off market," but we also work and share listings with other top brokerage firms.


We subscribe to co-star which is an international real estate listings service. If it is available for sale or lease, anywhere, especially in Manhattan and the rest of New York City, we know about it. We are also active in several worldwide referral programs. 

A frequently asked question is why we do not have a search engine on this site, so that you the customer can put all of your parameters down and then click "GO" so that space will appear. The answer is a simple one, which is that what comes out is often outdated and clearly will not suit your specific needs. My job is to do the hunting on your behalf, and then to present to you, often with amazingly fast turn-around, several appropriate options. Our research is unbiased, meaning that we do not steer you to a specific landlord's building or a specific broker--you do not know when you do random searches on "Googled" sites how the selected spaces are determined, and whose interest those listings serve. Our only priority is what suits you, and not unknown others.

At Longstreet, we do business in New York City, and beyond, below the radar and by using our 29 years of experience. Let us do your search, and then partner with you in order to find your business the perfect fit.
