One of the biggest mistakes companies make when renting retail, office or warehousing space is failing to pay proper attention to the detailed terms of a lease agreement. Tenants are often surprised to discover that the agreement includes provisions for escalations based on real estate tax increases, insurance costs, and common area maintenance expenses. For commercial properties, there really is no “standard form” and these leases are rarely straightforward. So review the contract carefully, preferably with your attorney, and be sure to raise any issues and concerns before the documents are signed to avoid unpleasant surprises later on.
