Real estate alerts for properties below market value
Real estate alerts the moment a below-market property appears. We search thousands of listings daily across 6 countries (Austria, United Kingdom, Czechia, Poland, Japan, Spain) so you never miss a deal.
How it works
We scan the market daily
Every day we collect new and updated listings from multiple portals in the countries we cover.
We compare against the average
Each listing's price is checked against the average for that region and property type, so we know the moment something is priced below market.
You get alerted instantly
The moment a below-market property appears - or an existing listing drops in price - you're notified in the app and by email.

About the app
Erterea sends real estate alerts the moment a listing across 6 countries matches your criteria or drops in price. We collect listings daily from leading real estate portals and compare them against the market average for that region and property type. The result is a clear picture of which properties are underpriced, how a listing's price has changed over time, and where the same property is cheaper if posted on more than one portal — whether you're searching for a home, investing in real estate, or running an agency.

Frequently asked questions
How is 'below market value' calculated?+
We compare each listing's price against the average price for similar properties - same region, property type and size - at the time it's scraped. A listing priced significantly below that average is flagged as below market value.
Which countries do you cover?+
We currently track listings in Austria, the United Kingdom, Czechia, Poland, Japan and Spain, sourced from multiple portals in each market and updated daily.
Is there a free trial?+
Yes - every new account includes a 30-day free trial with full access to your plan's features.
Can my whole team use one account?+
Yes. The Agency plan supports multiple team members across multiple office locations, with Owner, Leader and Agent roles and permissions.
How does buyer-lead matching work?+
When you log a buyer's search criteria - price range, area, property type, location - Erterea automatically checks every new listing against it and flags matches, so no one has to search manually.
Do you track price history?+
Yes. Every listing's full price history is tracked, so you can see how long it's been on the market and whether the price has dropped.
