Siena Property Prices, Rents & Rental Yields

About Siena

Siena blends a historic hilltop setting with a compact urban fabric, where medieval streets, landmark squares, and a strong civic identity shape the city’s appeal. For apartment investors, it is a location where heritage and day-to-day living remain closely intertwined.

August 2026 brings the clearest signal: prices are moving higher again, while rental income is not keeping pace in the same way. The average sale price for apartments has reached €285,000, after a month-on-month rise of 1.8%, and the average square-meter price is now €2,790, also up 1.8%. That points to a firming sales side, but not an equally strong improvement in income terms.

The tension is most visible in yield. At 4.61%, Siena’s apartment yield still offers a defined return, yet it sits against an average rent of €900 that has climbed 5.9% over the month while remaining 5.3% lower than a year earlier. In other words, the rental line is recovering in the short term, but it has not fully rebuilt the ground lost annually. For buyers, that makes August a month where capital values appear to be edging up faster than rental economics.

On a yearly basis, the pattern is just as mixed. The average sale price is up 1.8% year on year, while the average square-meter price is down 0.2%. Siena therefore reads as a market with modest price firmness, but with enough inconsistency across metrics to keep investment returns under close scrutiny.
