CoStar Group Inc. (NASDAQ: CSGP), a leader in commercial real estate information and analytics, has released a compelling report through its subsidiary, Homes.com, showcasing the most expensive publicly marketed home sales across major U.S. metropolitan areas for March 2026. This press release highlights the increasing demand for luxury real estate, particularly in high-profile cities, and underscores the continued vitality of the housing market amid economic fluctuations.

1. Record-Setting Sales in Major Markets

According to the analysis provided by Homes.com, the highest-priced home sale recorded in March took place in Miami, where a to-be-built mansion on the exclusive Indian Creek Island fetched a staggering $170 million. This sale not only sets a benchmark for Miami's luxury market but also emphasizes the city's allure to affluent buyers seeking exclusive properties.

The report details the top closed sales across key markets, revealing a strong trend in high-value transactions:

  • Miami: $170 million
  • Los Angeles: $47 million
  • New York City: $34.5 million
  • Phoenix: $20 million
  • San Diego: $14.5 million

An additional noteworthy sale in Houston’s Museum District, priced at $8.45 million, was acknowledged in the report but is not included in the main chart due to Texas's nondisclosure laws regarding home sale prices.

2. Insights into Luxury Market Dynamics

The distribution of these ultra-luxury transactions indicates a pronounced concentration at the very top end of the housing market, particularly highlighted by Miami's monumental sale. The report also reveals that several major metropolitan areas, including Los Angeles, New York City, and Phoenix, recorded transactions of $20 million or more, showcasing a robust geographic spread of luxury demand.

The analysis is based on multiple listing service (MLS) data sourced from Homes.com. It is essential to note that the findings focus solely on publicly marketed transactions and do not account for private or off-market deals, which are often prevalent in the ultra-high-end segment of the market.

3. Homes.com: A Leader in Real Estate Marketplace

As a rapidly growing residential real estate marketplace and a subsidiary of CoStar Group, Homes.com has positioned itself as a key player in the industry. Since its acquisition by CoStar Group in 2021, Homes.com has leveraged its advanced technology and marketing capabilities to connect millions of buyers and sellers.

In 2025, the Homes.com Network attracted an impressive average of 108 million unique monthly visitors, reflecting a significant increase in consumer brand awareness from 4% to 33% following a major marketing campaign launched in February 2024.
