All you need to know before applying for a home loan.

Buying a house is an important milestone for many and is only possible with a housing loan.  

However, this process is far from being just about signing a contract with the bank. It involves relevant financial decisions, knowledge about additional costs, and ensuring that all required criteria are met.

So, we gathered in a practical and accessible way everything you need to know to move forward safely and confidently. 

If you are thinking about moving forward, this guide will help you:  

  • Avoid common mistakes that can delay or make your credit unavailable.
  • Know all costs involved - in addition to the monthly installment.
  • Know what the bank analyzes before approving your request.
  • Understand the available financing options (including whether 100% financing is feasible);  
  • Gather all necessary documentation.

Is it worth taking out a mortgage loan?

Hiring a mortgage loan involves taking on a long-term debt. Before proceeding, it is essential to evaluate:

  • Financial capacity: Monthly installments should not exceed 30% to 35% of the family budget.
  • Total costs: In addition to interest, there are bank fees, taxes, and mandatory insurance.  
  • Alternatives: If possible, consider other funding or acquisition options.  

Despite the costs, acquiring a property represents the construction of one's own assets, offering security and potential future appreciation.

How much is the initial entry fee for housing credit?

Banks do not finance 100% of the property value. Typically, a down payment is required.

  • Own and permanent housing: Minimum down payment of 10% of the purchase price or appraisal value (whichever is lower).  
  • Secondary housing: Minimum entry of 20%.

For example, for a property of €280,000, you may need to have €28,000 to €56,000, depending on the purpose and evaluation.  

How to get capital for the entry of a housing loan?

To raise the amount needed for the initial down payment:  

  • Create a savings account or emergency fund: Separating money for the down payment helps prevent impulsive spending.
  • Reorganize the monthly budget: Identify and reduce unnecessary expenses;
  • Adopt saving strategies: Methods like "50/30/20" or the 52-week challenge can be effective.

How much does it cost to get a home loan?

In addition to the down payment, there are other costs to consider: how to know if I have financial capacity.

  • Taxes:  

Stamp Duty: 0.8% of the acquisition value.  

IMT (Municipal Tax on Onerous Property Transfers): Varies according to the value and location of the property;  

  • Bank commissions: They may include evaluation, opening, process study, and formalization, totaling between €500 and €1,300.
  • Mortgage Registration: Approximately 700€ cost.
  • Expenses after purchase: Condo fees, Property tax, maintenance, among others.  

How to know if I have financial capacity for a home loan?

Before applying for a loan, it is essential to analyze: how to know if I have financial capacity:

  • Effort rate: Percentage of monthly income destined to pay off credits. Ideally, it should not exceed 30% to 35%;  
  • Required documentation:  

Personal identification;  

IRS statements and income declarations;

Payroll receipts.

Bank statements.
