CoStar Group (NASDAQ: CSGP) published its September 2026 multifamily rent report through Apartments.com, showing a slight monthly decline in national rents.
The national average fell 0.08% to $1,752 from August's upwardly revised $1,753, ending nine consecutive months of positive to flat monthly changes. Annual rent growth accelerated to 1.5%, compared with 1.3% in August and 1.0% one year earlier. September's monthly decline was milder than the 0.2% decreases in both September 2024 and September 2025.
San Francisco led annual growth at 12.8%, while San Antonio recorded a 1.8% annual decline. The company said elevated supply continues to constrain national pricing momentum.
CoStar Group (CSGP) ranked Oklahoma City first, Hartford second and Cleveland third in its updated U.S. big-box logistics market analysis.
The ranking compares leasing activity, vacancy expansion and availability of newer properties across the 54 largest U.S. markets. Hartford’s logistics vacancy rate was 5.6%, with availability at 6.8%. Leases for spaces of at least 50,000 square feet averaged eight annually over the past two years, up from a pre-pandemic average of 6.2. Cleveland had the second-lowest availability rate for logistics buildings completed since 2020.
CoStar Group (CSGP) released an updated ranking of U.S. small-bay industrial markets on September 24, 2026.
Tampa ranked first and Columbus second in a Z-score analysis of the 54 largest U.S. markets. Tampa placed first for rent growth and third for leasing activity growth. Columbus ranked seventh for leasing growth and 15th for vacancy expansion. CoStar identified leasing activity and rent increases as reasons for Columbus’s second-place ranking.
The analysis compares leasing of spaces under 50,000 square feet over the past two years with a pre-pandemic average dating to 2015. It also considers vacancy expansion in properties of 10,000 to 100,000 square feet and inventory growth since 2015 in properties of 100,000 square feet or less. Rent increases are measured by comparing pre-pandemic averages with averages since 2023.
CoStar Group (CSGP) subsidiary Homes.com published its analysis of August's highest publicly marketed home sales across major U.S. markets on September 23.
The highest sale in the roundup was a newly built waterfront estate on Miami-Dade County's Hibiscus Island at $51.5 million; Cleveland's top sale was $2.8 million. Across nearly two dozen markets, top transactions averaged 6%, or $905,660, below their original asking prices. Each of the five leading sales in Tampa, Phoenix, Denver, Atlanta, Boston and Miami closed below asking. San Francisco was the only market analyzed with an average premium: its five priciest sales averaged 26.8%, or nearly $1.4 million, above original asking prices.
The analysis uses Multiple Listing Service data, which often excludes private and off-market sales. Homes.com evaluated Houston and Dallas properties by listing price because Texas is a nondisclosure state.
CoStar Group (CSGP), via its Homes.com marketplace, reported that the U.S. housing market saw the national median sale price reach $395,000 in August 2026, a 2.1% increase versus August 2025, despite slower activity and more homes for sale.
Home sales declined 4.3% year over year while overall inventory rose 5.4%. Among the 40 largest markets, 28 recorded annual median price gains, with Pittsburgh and Cleveland highlighted for strong performance, and Austin and Raleigh seeing price declines under supply pressure. By property type, single-family median prices grew 1.3% to $400,000, condominiums rose 1.9% to $349,087, and townhomes were flat at $360,000, while sales fell across all categories and inventory increased.
Homes.com describes the market as broadly balanced, with buyers more selective yet still supporting modest price appreciation. The platform reports 83 million average monthly unique visitors*, 115% year-over-year growth in organic search traffic, over 36,000 Member Agents, and an average additional $36,400 in first-year commissions for Member Agents**.
CoStar Group (CSGP) forecasts that Canada’s industrial vacancy rate will decline below 4% by the end of 2027, supporting a return to positive rent growth by late 2027.
The national industrial vacancy rate rose from 1.5% in 2022 to 4.75% in 2025 during a construction surge and weaker absorption, but has eased to 4.5%. The updated outlook calls for vacancy to fall to 3.25% by the end of 2028, versus a prior forecast of 3.5%. Net absorption, which was negative in early 2025, has averaged about 5 million sq. ft. per quarter since early 2026 and is projected to reach 7.5 million sq. ft. per quarter from Q3 2026 through 2027 before normalizing to about 5 million sq. ft. per quarter from 2028.
CoStar Group (CSGP) appointed portal veteran Felix Kusch as President of Homes.com, with Homes.com's leadership team reporting to him and Kusch reporting to Founder and CEO Andy Florance.
Kusch previously led Immoweb, Belgium’s number one real estate portal, and Immowelt, Germany’s number two portal, and has extensive M&A and board experience across European real estate marketplaces. The business model of the portals he has run aligns with Homes.com’s “Your Listing, Your Lead” approach, which the company says helps agents using Homes.com win 50% more listings by promoting properties rather than selling agent leads.
Kusch joins as CoStar’s residential segment posted its first profitable quarter, with second-quarter 2026 adjusted EBITDA of $12 million, a $41 million increase from the prior quarter. Homes.com revenue grew 66% year over year to $28.5 million, and CoStar’s network, including Homes.com and U.K. portal OnTheMarket, attracted 118 million average monthly unique visitors.
CoStar Group (CSGP) released an updated forecast indicating Canada’s overall office vacancy rate is expected to decline from 9.8% in the second quarter of 2026 to 9.3% by the end of 2027 and 8.7% by the end of 2028.
The vacancy rate had previously peaked at 10.4% in the second quarter of 2025. The new outlook is an improvement over CoStar’s prior forecast of 10% vacancy in 2027 and 9.4% in 2028, driven mainly by a thin construction pipeline rather than a demand surge. Net absorption is projected to average 1 million square feet per quarter in 2027 and 1.75 million in 2028, while net deliveries are expected to fall to 200,000 square feet by the end of 2027. Higher-end office assets are forecast to continue outperforming, with 4% rent growth versus about 2% for other assets.
CoStar Group (CSGP), through its Homes.com marketplace, released a New Construction Market Landscape Study outlining how new-home buyers in 2026 prioritize space, financial confidence and functional features.
The survey of over 3,000 U.S. adults aged 25+ with new-home budgets or purchase prices of at least $250,000, run at a 95% confidence level, found 51% used AI tools and 62% used them three or more times a week, while videos (42%), interactive floor plans (36%) and site plans (29%) guided virtual search. Larger homes or more space motivated 35% of buyers, and 64% work remotely at least one day weekly, with 74% rating a home office important and 49% wanting a second office. Seventy percent expect full structural and aesthetic customization. Builder choice hinged on material quality (57%) and experience (54%), ahead of financial incentives (30%). Buyers favored private backyards (51%), security features (47%) and flexible spaces (36) over purely aesthetic upgrades.
