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.
Kestrel is automated bookkeeping and portfolio organization for investors who want clean books and management report auditing at a low entry price. DoorVault is a different category. Knox, the AI inside DoorVault, unifies every property manager into one portfolio, consumes any document you forward or sync, reconciles statements against the bank, watches the whole portfolio overnight, and underwrites your next deal. Both keep clean books and catch what your PM misses. Only DoorVault runs the entire investor side on autopilot.
