For a higher yield from a protected position: a dominant supermarket in a small "central place" serves a population several times larger than the town itself, and planning law holds back new competitors. The chains go to such places themselves: REWE looks for sites in settlements of, as a rule, 5,000 inhabitants or more, EDEKA for a catchment of 4,000 or more. The price is a smaller pool of buyers on exit and of replacement tenants, so such a store is justified only with a long lease and a stable catchment.
What to check:
• the town's status in the central-place system under the state or regional development plan;
• the size of the catchment according to the municipality, and its population forecast;
• competitors within a ten-minute drive and new stores already approved;
• whether the site meets the chains' requirements for area, parking and room to expand;
• the remaining fixed lease term, excluding the tenant's options.
