In this segment, the speaker advises landlords to treat a mortgage as a self‑paying expense, emphasizing that only the interest portion counts as a cost because the principal merely reduces debt. He stresses the importance of accounting for all recurring property expenses—IBI, community fees, waste collection, and any other outlays—against the total rental income. Using a concrete example, he compares buying a single apartment outright for €60,000 (yielding €500 net per month) with financing three apartments priced around €65‑70k each, investing €20,000 per unit, and receiving €200 net per unit. By leveraging the mortgage, the investor can acquire more assets and achieve a higher real return on the cash actually invested, provided the profitability calculation includes all annual expenses.
