Due diligence is a comprehensive, complex, and critical stage in any commercial real estate acquisition. You don’t want to leave any stone uncovered, and you want the most time available to review all documents and look for potential red flags relating to the property, its title, tenant relationships, and numerous other considerations. That’s why we’ve created the checklist below, which outlines many of the key documents, records, and financial information typically required for a thorough due diligence review on a prospective property acquisition.
In many transactions, we recommend clients incorporate this checklist directly into the purchase and sale contract and require that the specified due diligence period will not commence until the date that the seller produces the last of each of these deliverables. Simply put, a potential buyer of a property, should have all the necessary documentation in hand before you start the intensive due diligence process.
Whether you are a growing business looking for your first independent location or a developer with an experienced deal team conducting diligence on multiple acquisitions simultaneously, we hope this checklist will serve as a helpful guide for the items you will need to make the most informed decisions on your next real estate acquisition.
