If an investor is unable to realise a return because he does not receive repayment from the beneficiary of his investment for the newly created benefit, this is known as the investor-user dilemma. The legal requirements to modernise the energy efficiency of residential buildings in order to achieve the German government's climate targets by 2050 are a recurring problem. This is why the term landlord-tenant dilemma is also used in this context.
