An honest look at both tools. Both audit your property manager and keep your books clean. Here is where each one wins, and how to decide.

DoorVault is the broader investor operating system: Knox consumes forwarded emails, uploads, and synced folders, reconciles statements to deposits, watches the portfolio overnight, and supports deal underwriting.
