How much a lender will let you borrow varies from bank to bank, but it will broadly depend on your income, living expenses, existing loan repayments as well as a few other variables. You can use uno’s borrowing power calculator here.
How much you can put down as a deposit will have a major impact on how much the bank will lend you. That’s because the bank wants to have a buffer between what you owe and what the property is worth on the open market. If you don’t have a deposit, you can read more about how uno can help you here.
