Here is a step-by-step guide on how to get a Spanish mortgage:

1. Determine how much you can afford to borrow and what type of property you want to purchase.
2. Shop around for mortgage lenders and compare rates and terms. There are many banks and mortgage brokers in Spain that offer a variety of mortgage products.
3. Gather the necessary documents. You will need to provide proof of income, such as pay stubs and tax returns, as well as proof of assets and liabilities. You may also need to provide a deposit or down payment.
4. Submit your mortgage application to the lender. This usually involves filling out an application form and providing supporting documents.
5. Wait for the lender to review your application and make a decision. This process can take several weeks or even months, depending on the lender and the complexity of your application.
6. If your application is approved, you will receive a mortgage offer detailing the terms and conditions of the loan. Review the offer carefully and make sure you understand all of the terms and conditions before accepting it.
7. Once you accept the mortgage offer, you will need to sign a mortgage contract and provide any additional documentation or information that the lender may require.
8. You will also need to arrange for a property valuation and have the property inspected to ensure that it is in good condition.
9. Once all of the necessary documents are in order and the property has been inspected, the lender will disburse the loan funds and you can complete the purchase of the property.
