The verdict in three sentences
A property developer website in Miami showcasing several new-build projects costs, in 2026, from 15,000 to 35,000 EUR excl. tax, depending on the number of projects, the granularity of unit sheets and search filters. 3D virtual tours are extra (2,000 to 5,000 EUR per project) and transform the contact rate. The real sales lever is the online pre-reservation funnel, which lifts qualified leads by 30 to 60 % by capturing intent at the peak moment.
2026 cost by scope
Budget depends on how many projects you manage and functional depth (unit sheets, filters, reservation, CRM).

| Project catalogue | unit sheets, filters, plans, availability | 21,000 - 28,000 | 11-13 wks |
| Lead platform | + pre-reservation funnel + connected CRM | 28,000 - 35,000 | 12-14 wks |

Karim, sales director at a Miami developer with 8 live projects. His old site produced 40 leads/month, 12 % qualified (5 useful leads). After a 30,000 EUR excl. tax site with a pre-reservation funnel and 3 virtual tours, volume rises to 65 leads/month at 22 % qualified (14 useful leads) — +9 qualified leads monthly. With an 8 % conversion to reservation and an average developer margin of 22,000 EUR per unit sold, the extra leads target roughly 190,000 EUR of additional margin per year.
FAQ
Do I need a CRM connected to the site? Yes once volume exceeds 30-40 leads/month: the CRM automates follow-up and scoring, exactly where cold leads are lost. Budget 3,000 to 7,000 EUR integration plus the tool subscription.
Are 3D virtual tours worth the cost? For off-plan builds with no show unit, yes: they increase time on page and reassure buyers. The extra (2,000 to 5,000 EUR/project) is quickly covered by one unit sold faster.
How do I manage real-time unit availability? A dynamic unit sheet linked to a spreadsheet or CRM shows available / reserved / sold, avoiding disappointment and adding credibility.
How long for a multi-project site? 12 to 14 weeks for the platform version, as unit-sheet modelling and CRM integration extend the schedule. A first project can go live earlier.
Is the pre-reservation funnel legally binding? No if designed as an expression of interest (application submission), not a reservation contract. Contract signing stays governed by off-plan sale law, outside the site's scope.
