Your real estate website generates qualified leads . Without depending on portals.




































What's holding your agency back every month.
You're funding your competitors' visibility.
€3,000/month for Immoweb. And when a prospect views your listing, the portal shows them similar properties from four other agencies. You're paying to generate leads you share with everyone. You're building no SEO asset of your own.
Updating a listing takes two days.
A property sold, a negotiated price, a new mandate. Every change goes through an email to the webmaster, a wait, an invoice. Meanwhile, your catalogue shows properties already sold. Prospects who call about an unavailable property don't call back.
Your neighbourhood pages don't exist.
A buyer searches 'apartment for sale Ixelles' or 'house with garden Uccle'. Your site doesn't show up because it has no dedicated page. The local intent is there, the searches exist, but it's Immoweb capturing that traffic.
What your site does for you after launch.
Your agents publish a property in 2 minutes, no developer needed.
Adding a mandate, updating a price, marking a property as sold: each agent does it from an interface designed for sales people, not developers. The site updates instantly. Each listing automatically generates its own SEO-optimised page for the neighbourhood.
Every lead lands in your CRM automatically.
Contact form, viewing request, online valuation: every interaction creates a qualified contact in your pipeline (Salesforce, HubSpot or other) with the relevant property and the source of the enquiry. No more manual re-entry, no more forgotten leads.
Your neighbourhood pages capture local traffic.
Page architecture optimised for geographic queries: 'apartment for sale Ixelles', 'office to let Etterbeek'. Real estate Schema.org markup, sub-1-second loading. And a GEO strategy to be cited in AI answers from Google and ChatGPT.
Photo galleries and virtual tours that drive clicks.
Performance-optimised galleries, optional 360° virtual tours or interactive floor plans. The design guides prospects towards a viewing request or contact, not towards Immoweb's homepage.
Three options for your online presence. Only one gives you control.
Immoweb and portals only.
Easy to get started, but you're renting your visibility. Every lead is shared with your competitors. Costs increase every year. If you stop paying, you disappear overnight.
WordPress + real estate plugin.
Customisable on paper. But the reality: plugins that break with every update, performance that degrades as the catalogue grows, security vulnerabilities to monitor. Your team spends more time maintaining the site than selling.
Custom site with self-managed catalogue.
Your agents manage the catalogue in 2 minutes. Integrated CRM, exclusive leads, local SEO by neighbourhood. The site belongs to you, loads in under a second, and every visit builds your SEO asset.
Full autonomy for your agents
Add a property, publish it, mark it sold. In 2 minutes.
From the admin interface, your agents add a new mandate with photos, price, surface area and location. One click to publish. One click to mark a property as sold. The site updates instantly.
Each listing automatically generates its own SEO-optimised page for the neighbourhood. When a buyer searches '3-bedroom apartment Ixelles', it's your site that shows up.

Proof by example
Coddy: 9 countries, each manager handles their content independently.
Coddy is my startup. Urban escape games for individuals and companies across 9 European countries. The platform runs on a multi-site architecture: each country manager accesses their own dashboard, manages their availability and updates their content without central intervention.
It's not real estate, but the challenge is the same: giving distributed teams the autonomy to manage their content, while keeping overall control. That's the logic I apply for your agents and sector managers.
Real estate pricing. No surprise quotes.
The price depends on the size of your portfolio, the number of agents and the integrations required. Zero platform subscription, the code belongs to you.
Frequently asked questions
How much does a custom real estate website cost at Numinam?
Three plans depending on the size of your portfolio. Showcase + Catalogue (up to 50 properties, self-managed catalogue, local SEO): €5,500 to €9,000. Lead Generation (50 to 200 properties, CRM integration, multilingual, neighbourhood pages): €9,000 to €16,000. Group or multi-agency (200+ properties, centralised back-office, ERP connection): from €16,000. The price varies based on the number of neighbourhood pages, integrations and automation level. Zero platform subscription, the code belongs to you. A 30-minute call is enough to scope your needs.
Can my agents manage the property catalogue without a developer?
Yes, that's the whole point. The admin interface is built for sales people, not developers. Adding a mandate with photos, price, surface area and location, updating a price, marking a property as sold: everything is done in a few clicks. The site updates instantly. Each listing automatically generates its own SEO-optimised page for the neighbourhood. During the mockup phase, I show you the admin interface before building it so your team can validate their daily tool.
Does the Numinam site integrate with Salesforce, HubSpot or our CRM?
Yes. I connect your site to your existing CRM: Salesforce, HubSpot, Pipedrive, or any other tool via API. Every form (contact, viewing request, valuation) automatically creates a qualified contact in your pipeline, with the relevant property and the source of the enquiry. No more manual re-entry, no more forgotten leads. If you don't have a CRM yet, I can advise on the best solution for your size and needs.
How does local SEO by neighbourhood work at Numinam?
The site is architected to capture geographic searches: 'apartment for sale Ixelles', 'office to let Etterbeek', 'house with garden Uccle'. Each neighbourhood has its own page, optimised with real estate Schema.org markup, location data and specific content. These pages are automatically enriched with available properties in the neighbourhood. The goal: appear at the top of Google when a buyer searches in your area — and be cited in AI answers from ChatGPT and Perplexity.
Can we keep Immoweb alongside the Numinam site?
Yes, and it's the recommended strategy to start with. The goal isn't to cut Immoweb overnight, but to build an exclusive lead channel that gains momentum. Your site progressively captures organic local traffic. Over the months, the share of direct leads increases and your portal dependency decreases. You decide the pace at which you reduce your portal spend based on concrete results.
How long before local SEO generates leads?
Local SEO is faster than general SEO. Well-optimised neighbourhood pages start appearing in Google results within 2 to 4 months for low-competition queries (specific neighbourhoods, precise property types). For more competitive queries ('apartment for sale Brussels'), expect 4 to 8 months. From launch, your optimised Google Business Profile generates visibility on Google Maps. SEO is a cumulative investment: each month, your positioning strengthens.
What happens if Numinam is no longer available?
The complete source code of your site is hosted in your own Git repository from day one. The project uses standard open-source technologies: any experienced developer can take over. Technical documentation is delivered at launch. Trusted associate developers are familiar with the tech stack and can step in if needed. Your site doesn't depend on a single person.
Is team training included?
Yes. Training on the admin interface is included in every plan. Your agents learn to add properties, edit listings, manage photos and mark sales — usually in a 1 to 2-hour session. User documentation is also provided for future team members. The back-office is designed to be intuitive: if your team can use a standard management tool, they'll be able to use the interface from day one.
