We love a challenge!

Optimal Spaces can help you turn critical and complex real estate issues into opportunities for growth and or cost reduction. We offer the experience, know-how, and the strategic planning that helps lead to better decisions. Virtually everything you need to enhance the value of your business (for profit and not for profit) , you will find at Optimal Spaces.

About Optimal Spaces
Optimal Spaces are Tenant Brokers, only representing commercial tenants, not owners or landlords. By contrast, managing agents and most commercial brokers are "landlord agents" representing the interest of owners. Their goal is to market and lease their clients' properties with the best possible terms for the owners. Thus, they will neither show you as broad a selection nor push to get the best price, since their loyalty is to the Landlord. An Optimal Spaces agent will show you a broader range of properties and offer you a broader range of important services than a managing agent or commercial broker will. We will provide you with a market survey, floor plans, pricing expectations , and access to our rolodex: Optimal Spaces walks you through the process from start to finish. Upon entering your new space, it will look the way you want, all at the price you agreed to spend. In addition to negotiating the best price, we will reveal and abate many "hidden costs" to you. We will show you all the relevant available spaces and safeguard your interests throughout the process. Because of tour costs to provide these services, we ask in exchange that clients sign an Exclusive Brokerage Agreement. This allows us to plan appropriately for assisting you with every step of the process.
