The verdict in three sentences
A real estate agency website is only useful if it generates listings, not just displays properties. In 2026 in Lille, a showcase site runs 6,000 to 16,000 EUR excl. VAT, plus 2,000 to 5,000 EUR for an automatic listings feed. An online valuation module converts 5 to 12 percent of visitors into a qualified seller lead.
What a real estate showcase site with a feed costs
Budget depends on the number of synced properties, the search/filter depth and whether a valuation module is added. Automating the listings feed is what separates a plain site from a real commercial tool.
| Line item | 2026 range (EUR excl. VAT) | Notes |
|---|---|---|
| Design + brand | 1,500 - 3,800 | Premium image, property showcase |
| Build + search engine | 2,000 - 5,000 | Filters, map, property pages |
| Listings feed (SeLoger/XML) | 2,000 - 5,000 | Auto import, daily updates |
| Online valuation module | 1,500 - 4,000 | Form, seller lead capture |
| Copywriting + local SEO | 1,000 - 2,800 | Neighborhoods, guides, linking |
| GDPR + forms | 500 - 1,200 | Consent, register |
A neighborhood agency targets 9,000 - 12,000 EUR excl. VAT with feed and valuation. Lead time is 6 to 9 weeks, with the listings feed setup the key technical step.
Miami: IDX/MLS integration in USD
For an agency targeting Miami, the equivalent of the French feed is IDX/MLS integration, with budgets in USD and MLS feed subscription fees to plan for.
| Element | Lille (EUR excl. VAT) | Miami (USD) |
|---|---|---|
| Full showcase site | 6,000 - 16,000 | 8,000 - 20,000 |
| Feed / IDX-MLS | 2,000 - 5,000 | 3,000 - 7,000 |
| Feed subscription (month) | 90 - 250 | 100 - 300 |
| Valuation module | 1,500 - 4,000 | 2,000 - 5,000 |
| Local SEO (month) | 600 - 1,800 | 900 - 2,500 |
| Maintenance (year) | 1,200 - 3,500 | 1,800 - 4,500 |
The valuation module is the true listing generator: it captures sellers at a moment of high intent and feeds the agency's pipeline far more effectively than passive property display.
Mini case study
Ms. Dubois, director of a real estate agency in Lille, invests 11,800 EUR excl. VAT in a showcase site with a SeLoger feed and valuation module. Previously the agency signed about 4 seller mandates per month. Six months later the valuation module generates 9 additional qualified seller leads per month, of which 3 convert into a mandate. At an average commission of 6,500 EUR per sale, three additional monthly mandates represent a potential of tens of thousands of euros in commissions, well beyond the site cost within the first quarter.
