Long Island Commercial Real Estate Market Research
Smart real estate decisions start with reliable market research. NAI Long Island tracks office, industrial and retail activity across Nassau and Suffolk counties, including vacancy, asking rents, absorption, new construction and sales trends. Our reports give owners, tenants, investors and lenders a clear, data-driven view of where the market stands and where it may be heading.

What Our Market Research Covers
Industrial
Long Island’s industrial market includes warehouse, distribution, manufacturing and flex buildings. Our industrial reports follow inventory, vacancy, rental rates and leasing velocity, along with notable transactions and the submarkets seeing the most demand.
Office
Office reports examine occupancy, sublease availability, asking rents and leasing activity across major office corridors. This research helps tenants plan renewals or relocations and helps landlords position their buildings competitively.
Retail
Retail market research looks at storefront availability, rent trends and the categories of tenants that are expanding, from restaurants and medical users to fitness and service businesses.
How to Use Market Research
- Tenants can compare asking rents and concessions before negotiating a new lease or renewal.
- Landlords can benchmark their buildings against competing properties and set realistic leasing strategies.
- Investors can evaluate pricing, cap rates and supply trends before acquiring or selling an asset.
- Lenders and advisors can support underwriting, valuation and planning with current local data.

Local Insight Backed by a Global Network
Published numbers are only part of the story. Our brokers add context from the deals they work on every day, such as which buildings are drawing the most tours, how landlords are structuring concessions and where buyers are finding value. As a member of NAI Global, we can also compare Long Island trends with markets across the country.
Key Metrics Explained
Vacancy rate measures the share of space that is physically empty. A falling vacancy rate usually signals growing demand, while a rising rate can indicate new supply or tenants giving back space.
Availability includes space that is currently vacant plus space being marketed that will become available in the future, such as sublease offerings or units whose leases are ending soon. It often gives an earlier warning of changing conditions than vacancy alone.
Net absorption is the change in occupied space over a period of time. Positive absorption means more space was leased than vacated, which is generally a sign of a healthy, growing market with steady tenant demand.
Asking rent is the rate landlords advertise for available space. Actual deal terms can differ once free rent, tenant improvement allowances and other concessions are factored in, which is why broker insight matters when you compare options.
Cap rate is a property’s net operating income divided by its value or sale price. Investors use cap rates to compare pricing between properties and markets, and changes over time can reflect shifts in interest rates and investor demand.
