Short Answer
A legitimate rental listing will never require you to immediately leave the platform to communicate exclusively via WhatsApp or private email. Real real estate agents must operate under strict transparency guidelines.
What Most Expats Don't Realize
You swiped through an incredible apartment listing on ImmoScout24 and moved the conversation to WhatsApp within minutes to beat the competition. You filled out a realistic application form and paid a dummy "brokerage fee" to secure a priority viewing slot that did not actually exist. You lost €450 to a shadow account because you prioritized speed over the standard legal process.
What To Do
- Download the listing images and run a reverse-image search on Google.
- Print out the contact page of the listing to verify the agent's name matches an official company with a German "Impressum" legal notice.
- "Können wir den Besichtigungstermin über das offizielle Portal vereinbaren?" (Can we arrange the viewing appointment through the official portal?) — ask the agent this to test if they are real.
The Truth
Platform filters can't catch everything. Scammers exploit the fact that expats are used to fast, digital services and don't know the standard German rental process.
