Researching your home’s ownership history beyond the last few residents requires digging into historical records and city directories. While the local deed office is the primary source, you can find a wealth of information in digitized U.S. Census records (available up to 1950) or historical city directories that list residents by address. If you click here for advanced property research guides, you can discover how to use Sanborn Maps or title abstracts to uncover names and architectural details from decades ago.
