Mainstay
System of intelligence for residential real estate.

Mainstay is an intelligence platform for residential real estate that helps brokerages and agents underwrite properties, manage listings, and make data-driven decisions. It provides tools for evaluating investment metrics like cap rates, gross yield, and IRR alongside comparable market analysis. The platform also supports brokerage operations with pre-MLS inventory management and offer comparison features.
Agents input property addresses and financial parameters to get automated underwriting, rental estimates, comps, and investment metrics, while brokerages control listing distribution and manage offer comparisons through a single platform.
