Did you get a response <| sep |> To find the bank with the best interest rate , you ' re going to have to shop around and do some leg work before meeting the bank . First of , you need to become knowledgeable . It takes a bit of time , but internet is your friend . On top of my head You need to know the vocabulary associated with a loan principal , interest , average annual proportional interest rate , . . You also need to have an idea of what ' s required in Spain in term of insurance and the kind of guarantee the bank will ask for lien or mortgage . Try and find if you can offer a lockup agreement you agree to put 4 or 6 mortgage payments in an account you can ' t touch , unless you can ' t make a payment You should also figure out all external costs to buying a house sale taxes , registry fees and have enough money to cover them out of pocket and have an idea of external costs linked to being a home owner property taxes , maintenance , . Figure out what loan you ' ll ask your banker how much money and for how long . There are plenty of online calculator to help you figure it out . Learn about under what condition you can make early payments on your loans much less common in Europe than in the USIf you can show your banker that you know what you ' re getting into and you ' re ready for it , it helps . And then , you need to be prepared to invest time in your search for the best rate List all the banks available in your area , and get an appointment with every single one of them . Come prepared have a file with all the documents the bank is susceptible to ask you for the loan , ready to hand in Even better have a summary sheet with all relevant information identity , contact info , data on the property you want to buy , and your numbers income , aftertax income , savings , etc . The best of luck to you and congrats !
