Mainstay

System of intelligence for residential real estate.

Visit Mainstay

Mainstay is a system of intelligence for residential real estate that connects data, decisions, and execution across buying, owning, and selling homes. It addresses the problem of work spread across disconnected systems and fragmented property data by bringing MLS listings, county records, HOA documents, tax assessments, permits, utilities, and neighborhood data into one platform.

Core workflows include underwriting, list price review, property tax review, and offer analysis, with outputs such as gross and net yield, NOI, cap rate, IRR, suggested list price ranges, AVM estimates, comparable sales, market velocity, and offer criteria checks. The platform also supports listing management for brokerages, covering pricing, offers, and distribution between MLS and exclusive inventory, with side-by-side offer comparison of terms, contingencies, and net proceeds.

Mainstay is aimed at investors, property managers, and brokerages. The pages do not describe a free plan, trial, editions, or seat-based and usage-based packaging.
