Yes: German banks routinely lend to property-owning GmbHs — including companies whose shareholders and directors all live abroad — against a charge on the property, the land charge (Grundschuld). The bank sets the rate deal by deal: it combines the cost of money for the fixed-rate period with a margin that depends on the loan's share of the property's value (LTV), the tenant and the remaining lease term. What matters is not the rate itself but how it compares with the property's yield: in our series' example the property earns 3.9% on the total outlay, and a loan that costs more lowers the return on your equity.
What to check:
• which value the bank bases the LTV on — the price, the market value or the lending value;
• the loan term and the fixed-rate period against the remaining lease term;
• a shareholder guarantee, subordination of the shareholder loan and the scope for a non-recourse loan;
• the assignment of rents and an account with the lending bank;
• early-repayment terms: on a sale, a fixed-rate loan can be terminated, but with compensation to the bank (§ 490(2) BGB).
