Boulogne-sur-Mer Property Prices, Rents & Rental Yields

About Boulogne-sur-Mer

Boulogne-sur-Mer pairs a working coastal setting with a historic urban core on France’s Channel coast. Its apartment market reflects that dual identity, combining seafront appeal, everyday city life and a compact local economy shaped by the port and surrounding Pas-de-Calais hinterland.

July 2026 brought the clearest signal in Boulogne-sur-Mer’s apartment market: prices remained firm even as rental growth stayed measured. The average sale price held at €145,100 month on month, while the average rent edged up 0.9% to €560. That leaves the market’s current yield at 6.06%, a level that still looks workable, but not immune to margin pressure when ownership costs or financing conditions tighten.

The deeper tension is visible in the annual trend. Over 12 months, the average sale price rose 11.6%, even though the average price per square metre was down 0.9% year on year to €1,920. In other words, headline values have advanced, but the underlying per-metre picture is softer than the annual sale-price figure suggests. Rents have also moved higher, up 6.7% year on year, yet they have not kept pace with the sharper rise in sale values. For investors tracking apartments in Boulogne-sur-Mer, July 2026 points to a market where pricing strength is real, but the income equation remains the key test.
