The amount you can borrow for a mortgage in Portugal will depend on several factors, including your income, debt-to-income ratio, credit score, and the type of mortgage you choose. Lenders will consider these factors when evaluating your application to determine how much they are willing to lend you and at what interest rate.

In general, most lenders in Portugal will allow you to borrow up to 80%-90% of the value of the property you are purchasing. This means that you will typically need to have a down payment of at least 20%-10% of the purchase price. However, some lenders may require a larger down payment, especially if you have a low credit score or a high debt-to-income ratio.

The maximum amount you can borrow for a mortgage in Portugal will also depend on your ability to make the monthly mortgage payments. Lenders will consider your income, expenses, and other debts when determining how much you can afford to borrow. It is a good idea to use a mortgage calculator or speak with a financial advisor or mortgage broker to get an idea of how much you may be able to borrow based on your specific circumstances.
