Saint-Louis Property Prices, Rents & Rental Yields

About Saint-Louis

Saint-Louis, in the Haut-Rhin department near the Swiss and German borders, sits at a strategic cross-border gateway. Its apartment market reflects that positioning, with pricing shaped by regional ties, commuter flows, and a compact urban setting.

September 2026 brings the clearest signal: rents are climbing faster than sale values, tightening the investment equation. The average apartment rent reached €980, up 2.1% month on month and 14.6% year on year, while the average sale price was €255,000, only 0.8% higher over the month and still 9.3% lower than a year earlier. That gap suggests a market where income growth is moving ahead of capital values, at least for now.

The same tension appears in the price per square meter, now at €3,960. It rose 1.8% month on month, yet remains 8.0% below its level from September 2025. For investors, that combination helps explain the current yield of 5.68%: apartment pricing has not recovered at the same pace as rents, so the monthly note is less about broad-based acceleration than about a market adjusting unevenly across income and value.
