The net initial yield (Nettoanfangsrendite) is the annual rent less the owner's non-recoverable costs, divided by the full purchase cost: the price plus real estate transfer tax, notary and land-registry fees and the broker's commission. Institutional investors compare properties on this measure, and it can sit well below the advertised figure: a store offered "at 5%" yields about 3.9% in our example.
• Which yield the seller quotes — gross or net — and which costs it has deducted.
• The non-recoverable costs under the actual lease: roof, structure, car park, management, insurance.
• Acquisition costs in the state concerned, including the broker's commission if the buyer pays it.
• The source and date of any market benchmark: a comparison makes sense only with the same broker's data for the same quarter.
• The basis of the calculation: the current net rent under the lease, not the rent expected after indexation.
