The verdict in three sentences
The make-or-break of real estate is seller mandates: an online valuation tool captures them at the source, when the owner is wondering about their property's value. Budget 8,000 to 25,000 EUR excl. VAT and 2 to 4 months for a tool that delivers a valuation range in exchange for a qualified form. The seller lead cost drops to 15-60 EUR, well below classic prospecting, with a conversion rate to valuation appointments clearly higher.
What a valuation tool costs in 2026
Price depends on calculation sophistication (market references, adjustments) and integration with CRM and campaigns. Here are the ranges.
| Tier | Content | Price excl. VAT | Timeline |
|---|---|---|---|
| Simple | Form + indicative range + email | 8,000-12,000 EUR | 2 months |
| Advanced | Market references, adjustments, PDF sent | 13,000-19,000 EUR | 2-3 months |
| Premium | Lead scoring, CRM sync, email/SMS sequences | 20,000-25,000 EUR | 3-4 months |
| Maintenance | Data updates, security | 100-300 EUR/mo | ongoing |
| Traffic (SEA/Social) | Seller acquisition campaigns | 500-2,000 EUR/mo | ongoing |
From click to mandate: the seller lead economics
A seller lead is worth far more than a buyer lead because it leads to a mandate, hence a commission. Here's the typical funnel observed.
| Stage | Typical monthly volume | Rate | Cost / value |
|---|---|---|---|
| Valuation tool visitors | 400 | - | SEA/SEO traffic |
| Completed valuations (leads) | 60 | 15 % | 15-60 EUR/lead |
| Valuation appointments booked | 18 | 30 % | Qualified |
| Signed mandates | 5-7 | 30-38 % | Commission 7,500 EUR avg |
| Closed sales | 3-4 | ~55 % | Agency revenue |
At the top of the funnel, 60 leads at 40 EUR cost 2,400 EUR; at the bottom, 5-7 mandates are worth tens of thousands of euros in potential commissions.

Mini case study
Thomas runs an agency in Montpellier with 3 agents. He invests 16,000 EUR excl. VAT in an advanced valuation tool and 1,200 EUR/mo in targeted seller campaigns. He generates 55 seller leads/month at an average 42 EUR/lead, i.e. 2,310 EUR of traffic. From there, 16 valuation appointments and 5 signed mandates/month. At a 55 % sale rate and an average 7,500 EUR commission, that's about 2.7 sales/month, i.e. 20,000 EUR of monthly commissions for an acquisition cost of 3,510 EUR (traffic + tool amortisation). The tool pays for itself in the first month of operation.
FAQ
How much does an online valuation tool cost in 2026? Between 8,000 EUR excl. VAT for a simple range form and 25,000 EUR excl. VAT for a premium version with scoring, CRM sync and automated follow-up sequences.
What seller lead cost can I target? Between 15 and 60 EUR depending on your market and campaigns, versus several hundred euros for a mandate won through classic field prospecting.
Does online valuation replace the agent visit? No: it gives an indicative range to open the contact. The physical appointment remains essential to refine and sign the mandate, but the tool qualifies and warms up the prospect.
What conversion rate should I expect? Count around 15 % of visitors completing the valuation, then 30 % booking appointments and 30-38 % signed mandates among those, a funnel far above a plain contact form.
Should I pair the tool with paid campaigns? Yes to accelerate: 500 to 2,000 EUR/mo of seller-targeted SEA/Social feeds the tool. Local SEO takes over mid-term to lower the cost per lead.
