Saint-Louis Property Prices, Rents & Rental Yields

About Saint-Louis

Saint-Louis sits at the crossroads of France, Switzerland, and Germany, giving it a distinctly cross-border identity in the Haut-Rhin department. For apartment investors, that setting adds a practical edge: the city is shaped by movement, proximity, and a market that often reflects wider regional pressures.

August 2026 brings the clearest signal: apartment values are easing while rents continue to climb. The average sale price stands at €253,000, after a 2.7% monthly decline and an 8.7% drop over the year. At the same time, the average rent has edged up to €960, up 0.8% on the month and 14.3% year on year.

That combination creates a sharper investment tension than the headline yield alone suggests. The gross yield is 5.13%, which still points to income potential, but it now sits against a softer pricing backdrop. The average price per square metre is €3,890, down 3.5% month on month and 8.5% lower than a year ago, indicating that capital values have adjusted more quickly than rental levels. For apartment buyers, Saint-Louis in August 2026 looks like a market where rent growth is preserving some income support even as sale prices and square-metre values remain under pressure.
