Built by an Operator, for Owners

Altis Stanza was founded by Vontay Callahan, a real estate entrepreneur and systems-builder who believes ownership should be simple, profitable, and transparent. We built Altis Stanza to give every client the clarity, tools, and team they need to win in real estate.

We operate nationwide, combining AI-powered systems with hands-on expertise across short-term rental management, revenue optimization, investor support, and brokerage — all under one roof.
