Commercial real estate differs from the residential real estate in several important ways. While residential purchases and sales are often based on a generic purchase agreement with blanks to fill in the details, commercial transactions are much more customized. The variety of types of the commercial real estate means that a one-size-fits-all approach doesn’t work. For example, one commercial property might involve environmental issues, while another might trigger zoning or land-use concerns. Often a transaction involves the purchase and sale of a business as a going concern, and this, in turn, gives rise to employment, corporate and tax issues. Commercial loans often involve personal guarantees, indemnification agreements, inventory and equipment financing and other issues that simply don’t arise on a house purchase.
