Castanet-Tolosan Property Prices, Rents & Rental Yields

About Castanet-Tolosan

Castanet-Tolosan sits just south of Toulouse, combining a suburban setting with easy access to the metropolitan economy. Its apartment market is shaped by the balance between local housing need and the pull of the wider Haute-Garonne area, making it a relevant location for long-term investors.

May 2026 brought the clearest signal yet: apartment pricing softened again, while rents showed a different trend. The average sale price stands at €199,000, after falling 2.9% over the month and 23.5% over the year. At the same time, the average rent is €690, which is still 15.2% higher than a year earlier, even though it slipped 11.0% month on month.

That divergence is what defines the current investment picture. The average price per square metre is €3,210, down 1.2% from the previous month and 7.4% below last year’s level, while the rental level remains elevated compared with May 2025. In yield terms, apartments offer 4.43%, a reading that reflects the tension between lower acquisition costs and softer short-term rents. For investors assessing Castanet-Tolosan this month, the market is less about momentum and more about how far falling sale values can offset the pressure from recent rent declines.
