Debt Repayment
In Singapore, home loans are contingent on the Total Debt Servicing Ratio (TDSR) limit. Under the TDSR framework your debt cannot exceed 60% of your income. This means all of your debts: car loans, student loans, credit card debt, personal loans, and of course, home loans. So managing your other debt will greatly increase your borrowing capacity.
The framework is similar in Hong Kong. The TDSR is calculated by dividing mortgage payments, property tax, and other debts by your income. Individual banks decide an acceptable TDSR, which is usually between 40-60%. Hong Kong also uses a Loan-To-Value (LTV) ratio to determine the size of your loan. It is typically 60-80% on the purchase price.
