What Sierra Realty does

Sierra Realty is a privately-held residential real estate brokerage headquartered in Coral Gables, Florida, serving buyers, sellers, and renters across Miami-Dade County. The firm is operated by Patty Sierra as the principal agent and focuses on the South Florida residential market, with visible listing exposure in luxury condominium developments such as Aston Martin Residences and the Ritz-Carlton. Historical scale commentary references 1,000+ customer outcomes, although the firm currently appears to operate as a single-agent practice with no disclosed team headcount or external capital.

The brokerage runs its business through a website platform powered by DPI Realty Websites, which integrates with the COTality Trestle API for MLS data ingestion and feeds listing syndication to third-party channels including Trulia. Customer-facing tooling includes an "Ask AI" natural-language property search, an "AI Median Home Values" predictive pricing feature, multilingual support (Spanish, Portuguese, Chinese, French, and others) oriented toward international buyers, and 30+ neighborhood-specific landing pages built for organic search acquisition across Miami-Dade submarkets.

The revenue model is standard real estate commission on individual residential closings, with no subscription, recurring, or enterprise revenue components disclosed. No funding rounds, acquisitions, partnerships beyond platform integrations, or executive hires are reported. Distribution is concentrated in owned website traffic, organic SEO across neighborhood pages, and syndicated listings; lead capture and conversion are managed through the website platform's standard real estate workflows.
