Mainstay

A connected record for each home

Mainstay combines listing, county, homeowners-association, tax, permit, utility and neighborhood information into a continuously updated record for each residential property. Its platform connects that data to decisions and execution across the asset lifecycle.

For owners and real estate operators, the record underpins workflows such as transaction execution, property-tax administration, HOA management and payments. The company describes an agentic automation layer that handles work across these processes, replacing fragmented records and manual tracking with a shared operational view.
