Problem
When the homeowner at a property already on file changes (e.g., the house sells), the integrator's only path is to create a new client record from scratch. That cleanly disconnects the new owner from all the project, system, and service history at the same physical address. The integrator who sold and installed the original system is often well-positioned to service the new owner — but they can't see what's there without manually cross-referencing the prior owner's account, item by item, every time a service call comes in.
Required capability
A "new owner at this address" flow that creates a fresh client record (separate billing, separate contact, separate communications) rather than overwriting the prior owner.
A structured link from the new client to the prior project, system, and service history at that address — visible to authorized users without having to open the prior owner's record.
Address-based search across clients so a service-call intake can look up a property and see what's installed, regardless of who currently owns it.
Configurable visibility — e.g., service techs and salespeople see installed-system details; the prior owner's billing / contact info stays gated to admins per privacy expectations.
Audit trail of the ownership transfer so it's clear when the property changed hands and which records were carried forward.
Why it matters
In residential AV and security, the installed system frequently outlives the owner. Real estate turnover at a serviced property is common over a 5–10-year horizon, especially in vacation-home and high-turnover suburban markets. The integrator's competitive edge is knowing what's already in the walls — but the data model today actively works against capturing that knowledge across an ownership change. Solving this turns prior-owner history into a moat: any competitor servicing the new owner has to start from a walk-through, while the original integrator quotes the upgrade or service contract from a known baseline.
