Choose the store's position in its catchment, not the town: a dominant supermarket in a small "central place" is often more resilient than a store in a metropolis, where prime yields stand at 5.00% — only about 1.5 percentage points above government bonds. Purchasing power matters less than it seems; planning status, competition and population trends matter more. The cost of entry also depends on the location: real estate transfer tax (Grunderwerbsteuer) ranges from 3.5% in Bavaria to 6.5% in four federal states.
What to check:
• the town's status in the state or regional development plan and its tier in the central-place system;
• the population forecast for the town and its catchment;
• competitors within a ten-minute drive and new stores already approved;
• the site's zoning and room to expand: the gap between the average store and retailers' requirements for new sites is about 450 m² for a supermarket and 250 m² for a discounter;
• the transfer tax rate in the state where the property lies.
