The problem Real estate agency sites are now a decade behind
For your customers, sellers and buyers alike, the first visit takes place online.
All agencies promise the same thing.
Free estimate, professional photos, distribution on portals. The owner who hesitates between several agencies opens as many tabs and reads the same text each time.
Your goods appear less good online than during the visit.
Photos crushed in a template, descriptions copied from the portal, no room to tell about the neighborhood. A property that appears mediocre on screen is a visit that will not take place.
Your forms mainly send you curious people.
Unclear budgets, out-of-area requests, curious about Sundays. An “I’m interested” form doesn’t filter anything: it leaves you with the sorting that your site should have done.
You rent your visibility on other people's sites.
Immoweb, Zimmo, Immovlan: several hundred euros per month for an audience that does not belong to you. The day you stop paying, you disappear.
The solution A site that presents your goods and sorts your requests
He works evenings and weekends, when your future clients are looking.
With this new website, you get more qualified requests.
And the image you send back corresponds to the work you do during your visit.
A brand that reassures before the appointment.
Your story, your sales made and the words of your customers, placed at the right moment in the journey. The seller arrives at the meeting already confident. The commission is then discussed much less.
A catalog that showcases your goods.
Each property has a real page: large format photos, narrated neighborhood, instant loading. Your mandates appear online as they appear on site. Your sellers can see exactly how their property will be treated.
Requests that arrive already qualified.
Project, budget, deadline: the forms ask the right questions before your phone rings. Each request arrives complete in your CRM, with its source. Your team calls back already qualified buyers.
Pages that respond to searches in your municipality.
Pages by municipality and by type of property, which respond to local searches on Google and in AI responses. These pages belong to you and gain value each month, instead of renting out like a slot on a portal.
Each project comes with its constraints
My job as a developer is to solve them.

Frequently asked questions
What should we prepare before requesting a real estate website quote?
Bring representative listings, your current property software, languages and the actions visitors need: request a viewing, ask for a valuation or contact an agent. Define who publishes properties and what happens when a listing is reserved, sold or withdrawn. Separate standard features from rules specific to your agency.
How much does a real estate website cost at Numinam?
A business website starts at €4,760 excluding VAT and a CMS website at €9,520. Property data, search, languages and CRM integration determine the actual scope. A catalogue managed by your agents needs its administration explicitly included. The website budget guide helps compare formats and running costs.
Can our agents update property listings themselves?
Yes, when that publishing workflow is included in the project. Before approving it, have an agent add a property, edit a price, replace photos and change its status in the proposed interface. Define required fields, publishing rights and how quickly updates appear on the public site.
Which system should hold the property record?
If your existing property software remains authoritative, specify the fields imported and how status changes reach the website. Decide what can be edited locally and what happens if synchronisation fails. A withdrawn property should not keep accepting viewing requests without warning.
How should enquiries reach our CRM?
Each enquiry should include the property reference, the visitor's request and its source when available. Define contact matching, agent assignment and failed-transfer alerts. Test an existing contact, an incomplete enquiry and a repeated submission. The software integration guide explains data ownership and recovery.
Can we keep property portals alongside our own site?
Yes. Compare direct and portal enquiries by quality, handling time and cost before changing the channel mix. Your site can present the agency's work and receive direct requests; growing that channel is not a guaranteed replacement for portal traffic.
What should the migration and handover include?
Inventory active listings, photos, useful URLs and records to retain. Test an import and the redirects, then decide which system is authoritative at launch. The agreement should specify training, account and code access, exports, maintenance and handover to another supplier.
