Brownfield Listings is an online marketplace dedicated to challenged properties—often known as “brownfields”—where some real or perceived difficulty is impacting the value of the property, complicating its sale, frustrating its redevelopment or otherwise limiting its potential. BrownfieldListings.com connects buyers and sellers, but it is more than a list of distressed properties. Both property marketplace and shared workspace, Brownfield Listings is a market to offer real property for sale, as well as a forum to introduce property redevelopment ideas. Sellers can list a property for sale to registered buyers, post a RFP for a specific project for response by registered vendors, and publish a property for public comment to allow the public to participate directly in the redevelopment process. Now sellers can easily market their property nationwide and connect to the local community from a single platform. Sellers can daylight the due diligence process by opening it to a wider audience of professionals, community residents and/or the general public— to publish and archive important information, to generate community support, and to crowd source ideas. We simplify the process with tools that make it easier to create higher quality due diligence and publish it to a targeted audience. Built as a due diligence engine, BrownfieldListings.com gives all stakeholders a common digital infrastructure designed for the unique diligence and data demands of brownfield transactions and property redevelopments. Now buyers and vendors have access to a fresh database of detailed property due diligence in a simplified and standardized format, delivering unmatched depth and quality of property and project data. Brownfields are properties with questions. Brownfield Listings is the platform where answers are developed and brownfield success stories are built.
