Your credit rating and history: The lending bank may look into your mortgage payment history, instalment debt payment history and credit card/credit use history. If you have been making regular, timely payments on all debts, you will likely be deemed as a “safe” borrower.
Your collateral: As your home will be used as collateral for your loan, the value of your home is an important factor in how much a bank will be willing to lend you.
Your capacity to repay a loan: A bank will determine is you have the capacity/ability to repay your loan, based on your monthly income, household expenses and total debt. The lender may also take into account other sources of funds, such as bank accounts, bonds, stocks, mutual funds, etc.
