Our team has the most comprehensive view of the commercial real estate leasing process.
Our Story
Founded in 2010, with decades of experience and expertise. Quite simply, the people behind LeaseCalcs have the most comprehensive view of the commercial real estate leasing process, from start to finish, in the industry. Not only have we participated in the negotiation of literally thousands of leases, but we've analyzed, audited and accounted for thousands more. We have taught brokers and tenants how to better negotiate their leases, taught attorneys how to draft lease provisions in relation to the lease accounting rules and their clients' economic best interests, and taught finance and accounting professionals about the nuances of the forthcoming lease accounting changes. Because of our deep experience in all of these facets of the leasing process, LeaseCalcs is able to provide a patented application that solves an enormous, multi-faceted problem for everyone involved in the negotiation, analysis, approval, accounting and administration of commercial real estate leases. Better yet, we made it easy to use and affordable.
