[Note from editor: The “Mastermind Showcase” highlights companies and news from members of the GEM. Today’s showcase: CondoBlackBook.]

CondoBlackBook allows home buyers and renters to explore condos and neighborhoods in Miami. Their entire search experience is built on curated condo inventory, and each listing gives condo buyers access to detailed information including floor plans and price history. They’ve aggregated building level photos, descriptions, as well as sales history and statistics. Property guides contain detailed neighborhood descriptions, historical background, and favorite places to eat, drink, and play.

CondoBlackBook was founded by H B Roswell Realty, a boutique luxury real estate brokerage in the Greater Miami Area.

What we like: A compelling curation play, CondoBlackBook is laser focused on serving the needs of buyers with specialized market knowledge. Making an actual promise to customers (most detailed condo knowledge available) gives them a leg up on legacy models.
