The verdict in three sentences
A high-performing agency website is not a brochure: it's a machine to capture buyers and seller mandates, with map search, email alerts and local SEO on target neighbourhoods. Budget 12,000 to 35,000 EUR excl. VAT and 3 to 5 months depending on customization and integration with your transaction CRM. The return is measured by the contact rate, which climbs 20 to 40 % when search is smooth and listings are optimised.

Sophie runs an agency in Nantes-Chantenay with 4 agents. Her old site generated 12 contacts/month. After a 24,000 EUR excl. VAT rebuild with map search, alerts and neighbourhood SEO pages, the contact rate rose 30 % and organic traffic doubled in six months: 26 contacts/month, including 8 seller leads via online valuation. At a 4 % conversion rate and an average 7,500 EUR commission, those 14 extra monthly contacts represent roughly 50,000 EUR of additional annual commissions, a payback in under six months.
