Rent can exceed interest while principal repayments still reduce available cash
Assume a hypothetical price of 100, debt of 50 and equity of 50. Annual rent of 2.7 less operating costs of 1 gives net operating income of 1.7. With a loan rate of 2.5%, interest is 50 × 2.5% = 1.25 and cash after interest is 0.45. The cash yield on equity is 0.45 ÷ 50 × 100 = 0.9%. Repaying annual principal of 1 then leaves available cash of -0.55. Principal repayment reduces debt but consumes cash, so distinguish profit, returns and debt-service capacity.
Check for yourself
- Does the advertised yield include vacancy, management, repair reserves and taxes?
- Does the loan require interest only or principal too, and when does its rate reset?
- Does yen cash flow converted to won still fit the goal after acquisition and disposal costs?
Limits of application
100, 50, 50, 2.7, 1, 1.7, 2.5%, 50 × 2.5% = 1.25, 0.45, 0.45 ÷ 50 × 100 = 0.9%, 1 and -0.55 are hypothetical. This simple annual calculation estimates neither actual property returns nor loan approval. Currency moves, acquisition and disposal costs, income tax and price changes are excluded. Check actual quotations to establish what operating costs include.
- What to look for
- Examine how price, rent, management and borrowing interact in a broker’s discussion of Tokyo tower condominiums and small buildings.
- Why it matters
- Separate yield denominators, expenses, cash flow after principal repayment, currency exposure and disposal costs, then compare claims with public transaction data, contracts and official rules.
Timeline
9 segmentsThe proposal is to collect rent, service interest and principal, and seek appreciation using low-cost borrowing. Comparing the whole asset’s yield directly with the rate on only the borrowed portion does not establish a multiple of investment return. Include expenses, repayments, currency exposure and exit terms; location and past gains guarantee neither future appreciation nor debt-service capacity.
