    What can make the bank refuse a home loan?

    Applying for a home loan is one of the most important steps in the home buying process, and it is also one of the phases that brings the most doubts. After all, after finding the right property, no one wants to hear that the loan was rejected, but it is important to understand one thing from the start: a rejection does not mean that buying a house is no longer possible, often it just means that there is some point in the process that needs to be reviewed more carefully.

    Loan approval always depends on the financial institution's analysis. The bank evaluates several factors before deciding whether or not to grant financing: income, professional stability, other loans, credit history, property value, down payment, and documentation.

    1. High debt-to-income ratio

    The debt-to-income ratio is one of the main factors analyzed by the bank. Simply put, it shows what portion of the customer's monthly income is committed to loan payments.

    For example: if a family receives 2,000 euros per month and already pays 500 euros in loans, the bank will analyze whether there is still room to take on a new house payment.

    The financial institution's objective is to understand if the family can pay the loan without being too pressured every month, because it is one thing to be able to pay the installment in a normal month, and another to continue to be able to pay if an unexpected expense arises, an illness, a reduction in income, or an increase in interest rates.

    When the debt-to-income ratio becomes too high, the loan may be rejected.

    2. Insufficient or unstable income

    The bank also evaluates the client's income. It does not only analyze the amount that comes in every month, it also analyzes the stability of that income. A worker with an open-ended contract and regular income may have a different analysis from someone with variable income, recent freelance receipts, or unstable commissions. This does not mean that self-employed workers or people with variable income cannot have their loan approved, it just means that the process may require more documentation and more careful analysis. The bank needs to understand if there is capacity to pay the loan for several years, not just at the time of application.

    3. Credit history

    Financial history also weighs on the decision. If there have been payment delays, defaults, or overdue debts, the bank may consider there to be a higher risk, so, before applying for a home loan, it is useful to consult the Credit Responsibility Map at the Bank of Portugal. This document shows existing loans, outstanding amounts, terms, and any recorded situations. Having other loans does not automatically mean that the application will be rejected, but delays, defaults, or excessive liabilities can make approval difficult.

    4. Existence of other loans

    Car loans, personal loans, credit cards, equipment payments, or other financing are included in the bank's analysis, even if the client has good income, if a significant part of the budget is already committed to other loans, the new house payment may be considered too heavy. In this case, the problem is not necessarily with the chosen property, it may be with the total monthly expenses. In some situations, reorganizing or settling existing loans before proceeding with the application can improve the analysis.

    5. Property valuation amount

    Another common reason is related to the bank's appraisal of the property. The bank does not only analyze the agreed price between buyer and seller, it also requests a property appraisal to understand its market value.

    If the appraisal comes in below the purchase price, a problem may arise.

    Imagine a house costs 250,000 euros, but the bank's appraisal is 230,000 euros. Financing may be calculated based on the lower value, which means the buyer will have to have more own capital to cover the difference. When that difference does not exist, the process may be at risk.

    6. Lack of down payment

    In most cases, the bank does not finance 100% of the house purchase. This means the buyer needs to have money available for the down payment, in addition to the costs associated with the purchase, such as taxes, deed, and other charges. Many people only consider the monthly payment, but forget about the amount needed before the deed. The lack of a down payment can prevent loan approval, even when the monthly payment seems affordable.

    Before proceeding, it is important to understand:

    • the maximum amount the bank can finance;
    • how much will be needed for the down payment;
    • what taxes will have to be paid;
    • what are the deed costs;
    • what financial margin should be available after the purchase.

    Buying a house should not leave the family without financial breathing room.

    7. Incomplete or inconsistent documentation

    Sometimes, the difficulty is not in financial capacity, but in documentation. Missing documents, outdated information, poorly proven income, or inconsistent data can delay the process and make approval difficult.

    The bank needs to confirm who the client is, how much they earn, what financial responsibilities they have, and the property's situation.

    Normally, documents such as:

    • identification document;
    • IRS declaration and settlement note;
    • payslips;
    • employer's declaration;
    • bank statements, when applicable;
    • Credit Responsibility Map;
    • property documentation.

    A well-organized process conveys more confidence and avoids unnecessary delays.

    What to do if the home loan is rejected?

    The first thing is to understand the reason for the rejection.

    • Was it because of the debt-to-income ratio?
    • Of income?
    • Of other loans?
    • Of the property valuation?
    • Of the lack of down payment?
    • Of the documentation?

    Only after understanding the reason is it possible to correct the path.

    In some cases, it may make sense to look for a property with a more adjusted value. In others, increase the down payment, settle other loans, correct documentation, or wait for greater financial stability.

    The important thing is not to view the rejection as an automatic end point. Often, it is just a sign that the process needs to be prepared differently.

    How can credit intermediation help?

    Credit intermediation can help the client better prepare the application before it reaches the financial institution.

    The credit intermediary does not approve the loan. That decision always belongs to the bank, but they can help gather documentation, understand critical points, compare available options, and support the client throughout the process.

    For those buying a house, this can bring more clarity, fewer doubts, and less stress.

    Buying a house already involves many decisions. Having support with the financing part can make the journey simpler and safer.

    A home loan can be rejected for several reasons: high debt-to-income ratio, insufficient or unstable income, credit history, other loans, property valuation below expectations, lack of down payment, or incomplete documentation.

    But a rejection does not always mean the end of the road.

    Often, it means that the process needs to be reviewed, some points adjusted, and then proceeded with more preparation.

    At SCI Finance, we support clients in this phase so that every decision is made with more information, more clarity, and more confidence. Because buying a house should not be a race full of doubts. It should be a supported, conscious, and safe process.
