Room to grow
No gaps confirmed. Some checks could not be completed for this portal, so there may be room the audit could not see.
What to ask for
Building on the protections already in place, you might consider a property-owner notification system (like the ones AZ, FL, HI, IL, and UT have implemented) and a formal data-governance policy that addresses commercial data aggregators.
