A buyer in Miami looking at a $2M condo wants the same answer a stock buyer wants: how has this asset performed, and how does that compare to the alternatives on the same street. The listing portals don't surface that — they surface marketing. Our client, a Miami real-estate professional, asked for the opposite: a research-grade web app that takes verified closed sales from public records, rolls them up to the building level, and gives a realtor a defensible answer to "should I buy here." We shipped it as miamicondoanalytics.com.
