Val-d'Oise is a department of France located in the northern part of the Île-de-France region. Covering over twelve hundred square kilometres, it shares borders with several neighbouring departments, including Seine-Saint-Denis, Hauts-de-Seine, Yvelines, Eure, Oise, and Seine-et-Marne.
The housing market in Val-d'Oise is slightly cheaper than the national average for France. Housing is distributed across several key towns rather than being concentrated in a single major city. Cergy and Argenteuil hold the largest shares of the housing stock, closely followed by Bezons and Pontoise. Prices vary notably between these areas. Cergy and Goussainville are the more affordable options in the department, with prices sitting well below the regional average. In contrast, Cormeilles-en-Parisis is the most expensive town for buyers, with property prices there rising far above those found in the rest of Val-d'Oise.
