A method to finance data centers and other high infrastructure facilities provides suitable collateral to close real estate financing. The method has three portions : vetting of suitable projects upon a computer, assembly of select tax credits upon a computer, and formation of capital as collateral for financing. This invention finds a building that fits the criteria for a government preservation program. Then the invention obtains collateral for financing the building renovation or rehabilitation from governmental agencies in connection with the building. Next the invention finds a third party interested in the collateral that invests in a building project or ownership of the building in exchange for the collateral. The investment funds then provide a down payment for the financing. The collateral may have the form of a federal tax credit. The method promotes financing of structures that may otherwise not obtain financing for reconstruction into a new use.
