ShadowKey provides rental property maintenance coordination for small, self-managing landlords who want to spend less time handling repairs without hiring a full-service property manager. When a renter reports a maintenance issue, ShadowKey gathers the details, contacts local service providers, collects and follows up on vendor quotes, coordinates scheduling, and tracks the work order through completion. Landlords stay informed, set their own approval limits, and make the final decisions when needed. Renters and vendors can communicate by text without downloading an app. Landlords pay vendors directly, with no markup added to vendor invoices.
