New and enlarged food stores in Germany are generally let for 15 years; the rent is linked to the consumer price index but usually rises only after a threshold and often by less than full inflation. Costs are shared on a "double net" basis: the roof and structure remain with the landlord, and in our experience a new store's owner bears non-recoverable costs of 8–15% of the net rent. There is no single market standard: the economics of a property are set by the wording of the particular lease.
What to check:
• Find out who signed the lease — a group company or an independent merchant — and whether there is a group guarantee.
• Calculate the remaining fixed term without the tenant's options.
• Check the index, the threshold and the share passed on, and whether a threshold already crossed has been missed.
• Check the list of recoverable costs and the allocation of repairs: roof, structure, building services, car park.
• Request the full chain of amendments and make sure each one is at least in text form.
