An agent website with listings — more owners, more buyers
We build professional websites, apps, online shops and custom systems — with the quality of big agencies but without their overhead. Specialised in Germany's small and medium businesses.

In short
A real estate agent website starts at €1,490 net — with property listings, portal/IS24 integration, an owner-acquisition form (valuation), GDPR-compliant and mobile-optimised.
Owners decide online who they entrust with their property — and buyers have long searched for listings on the web first. An agent website with a well-maintained listing is therefore your shop window around the clock. A firm that appears professional and is easy to find wins both sales mandates and serious buyers.
Rhein Code builds real estate agent websites that present properties attractively while convincing new owners of your competence. They show current listings, make the valuation request easy, and gather buyer inquiries cleanly. At a fixed price from 1,490 € net, transparently calculated.
As a digital studio based in Düsseldorf, we know the requirements in Germany: a correct legal notice (Impressum), GDPR-compliant inquiry forms, and the duty to include energy certificate data in listings. Service in German, English, and Arabic — a real advantage with international buyers.
Typical challenges
- Listings only show on portals — your own brand is missing
- Winning owners for new mandates is hard
- The website offers no property-valuation request
What we build for your agency
- Property overview with detail pages and gallery
- Owner acquisition: "What is my property worth?" form
- Portal integration/import (ImmoScout24, OpenImmo) possible
- Local SEO: "estate agent + city", "sell house + town"
Real Estate Agents
What your website or solution delivers
Property listing with detail pages
Each property gets its own page with an image gallery, key facts, location description and an inquiry button. Buyers find everything essential at a glance and you look instantly professional.
Manage listings without a developer
You add new properties yourself, change prices and mark sales as 'sold' through a simple system. On request we connect existing portal interfaces.
Valuation request for owners
A clearly placed 'What is my property worth?' form brings you sales mandates. Owners enter key data and you receive qualified leads instead of anonymous clicks.
Buyer inquiries cleanly bundled
Prospects inquire directly about a property, including a preferred viewing date. You no longer lose an inquiry in a cluttered inbox.
Energy certificate and mandatory data
We build the fields for the legally required energy certificate details directly into the listing. This keeps your ads compliant and complete.
GDPR-compliant forms and cookie banner
All inquiries run encrypted with clear consent and a privacy notice. We set up the legal notice, privacy policy and cookie banner correctly.
Multilingual presence
On request we build your agent website in German, English and Arabic. You reach international investors and buyers exactly where other agents stop.
Local visibility and fast mobile view
We optimize your site for searches like 'real estate agent Düsseldorf' and make sure listings load quickly and attractively on a smartphone. That is exactly where most buyers search.
In practice
Real-world examples
An agent who wants more sales mandates
An agent has enough buyers but too few properties. A prominent valuation request specifically captures owners considering a sale and fills the pipeline.
A solo agent with a growing portfolio
An independent agent wants to publish properties online without commissioning a provider each time. A simple listing system makes them independent and fast.
An agency with international clients
An agency also sells to English- and Arabic-speaking investors. A multilingual listing speaks directly to this high-value audience.

Direct contact with the developer

Data on EU servers
