CoStar Group (CSGP) released a new forecast on Canada’s retail property market following the 2025 closure of Hudson’s Bay stores.
The forecast projects the overall retail vacancy rate will remain near 2.5% over the next year, after rising from 1.8% when the Bay closures pushed mall vacancy from 3% to 8% and net absorption to negative 5 million square feet in the second quarter of 2025. Retail construction is described as the weakest in a decade, with starts below 1 million square feet per quarter since the third quarter of 2025 and only about 5 million square feet under construction in the second quarter of 2026, the lowest level since the pandemic.
Rent growth has slowed from about 4% in the first quarter of 2025 to just above 2% in the second quarter of 2026 and is expected to bottom around 0% by the second quarter of 2027 before recovering to about 3% by the end of 2028.

The company reports that referral traffic from ChatGPT to Apartments.com has increased nearly 40% since the app launched in early August. OpenAI featured Apartments.com in an apartment-hunting demo for GPT-6 Astra, and Apartments.com expects to further expand the app with additional proprietary data, design improvements and new capabilities.
Apartments.com (CoStar Group, CSGP) reports that U.S. multifamily rents were essentially flat in August 2026, with the national average edging down 0.03% to $1,751, ending eight consecutive months of positive monthly gains.
Despite the slight monthly dip, annual rent growth improved to 1.3%, up from a revised 1.1% in July and 1.1% a year earlier. Regional results were mixed: the Pacific led monthly growth at +0.1%, while the South and Mountain regions each declined 0.2%. Year over year, the Pacific and Midwest rose 2.2%, the Northeast 2.0%, while the South and Mountain fell 0.1% and 0.5%, respectively.
Among major metros, Orange County led August with +0.6% monthly growth and San Francisco led annually at +11.9%, while supply-heavy markets such as San Antonio (-2.2%) and Denver (-1.9%) saw annual declines.
CoStar Group (NASDAQ: CSGP) released a new forecast on Canada's multifamily market, projecting that national vacancy rates will start trending down in the second half of 2027 as net absorption outpaces moderating new deliveries. According to CoStar Group, national multifamily vacancy has risen from about 2% in 2022 to 4.75% today, driven by net deliveries averaging 8,000 units per quarter since 2023. The firm highlights a split market: vacancy is about 3% for low-end units versus roughly 15% for high-end units, up from about 7% in 2022. CoStar Group expects net absorption to begin rising at the end of 2026, while warning that trade and tariff uncertainty, higher fuel costs and a declining population could weigh on outcomes, with longer-term equilibrium depending on immigration targets.
CoStar Group (NASDAQ: CSGP) released a new report showing that rapid growth in data center development is driving a rising share of U.S. industrial real estate demand. National data center inventory has reached roughly 69 gigawatts of existing capacity, with another 43 gigawatts under construction. In 2026, data center-adjacent tenants accounted for more than 6% of leasing at logistics properties within five miles of data centers, up from less than 3% in 2020, spanning construction, power and cooling equipment, operators and IT infrastructure providers.
According to CoStar Group, hyperscale facilities now represent 64% of existing capacity, reflecting expansion by major technology companies. Dallas-Fort Worth leads major markets with approximately 10 million square feet of occupied logistics space leased by data center-adjacent industries since 2025, followed by Houston, Atlanta and Phoenix. The report highlights that operators increasingly favor locations with strong power infrastructure, extending demand into the broader supply chain needed to build and run these facilities.

Homes.com (part of CoStar Group, NASDAQ: CSGP) released an analysis of the most expensive publicly marketed home sales across major U.S. metros for July, using Multiple Listing Service (MLS) data.
The top sale was a Bel Air estate in Los Angeles at $130 million via foreclosure auction, while the lowest among the highlighted markets was Cleveland at $3.72 million. Other leading prices included New York City at $47 million, Phoenix at $40.2 million, Miami-Dade County at $40 million, Seattle at $21.2 million, Tampa at $19 million and Boston at $18 million.

The analysis excludes many private/off-market deals and evaluates Houston and Dallas based on listing prices due to Texas nondisclosure rules.
