Mortgage loan: rates, requirements and application — the complete guide to getting approved

🔎 Introduction

Buying a property is often one of the most significant financial decisions in a lifetime. In most cases, it relies on securing a bank loan. Yet many borrowers approach this step without fully understanding the rules, which can lead to rejections, unfavorable terms, or a poorly optimized investment capacity.

Securing financing is not solely about income. Banks assess a range of criteria, including job stability, account management, debt level, personal contribution, and the overall consistency of the project. Understanding these expectations from the outset allows borrowers to position themselves more effectively and significantly improve their chances of obtaining financing under good conditions.

This article aims to clarify the key elements to understand before applying for a mortgage. From calculating your debt ratio to analyzing the APR (Annual Percentage Rate), as well as building a solid application and adopting the right practices, the goal is to provide a clear and practical overview of how access to real estate financing works today.

🧩 Types of mortgage loans

There are several types of mortgage loans, each designed to meet different needs and strategies. Understanding their specifics helps in choosing the most suitable financing for your project.

The amortizing loan

This is the most common type of mortgage. Each monthly payment includes both a portion of the principal and interest. Over time, the interest portion decreases while the principal repayment increases. This model is simple, transparent, and secure, making it the standard choice for most property purchases, whether for a primary residence or a rental investment.

The interest-only loan

In this structure, the borrower pays only the interest throughout the loan term, with the principal repaid in full at maturity. This type of loan is mainly used in wealth or tax optimization strategies, particularly in rental investments. It typically requires a significant contribution or parallel savings (such as life insurance or collateral), as it presents higher risk for the lender.

The bridge loan

A bridge loan is designed for buyers who purchase a new property before selling their current one. The bank advances part of the value of the property being sold, enabling the new acquisition. This loan is temporary, usually lasting between 12 and 24 months, and carries a risk if the initial property is not sold within the expected timeframe or at the anticipated price.

Government-supported loans

Certain schemes are designed to facilitate access to homeownership under specific conditions. The most well-known is the interest-free loan (PTZ in France), reserved for first-time buyers and subject to income limits. Other forms of support may exist depending on the borrower’s profile or geographic area. These loans are generally used alongside a primary loan and help reduce the overall cost of financing.

Each type of loan follows a different logic. The choice depends on the borrower’s profile, strategy (primary residence or investment), holding period, and overall financial capacity.

🏦 Key criteria assessed by banks

Before granting a mortgage, banks carefully analyze the borrower’s profile to assess their ability to repay over time. This evaluation is based on several complementary criteria.

Income and job stability

Income level is central, but it is always assessed alongside stability. A permanent contract (CDI) outside of probation remains the most reassuring profile for banks. Self-employed individuals, entrepreneurs, or those on fixed-term contracts can still borrow, but they often need to demonstrate several years of stable activity and consistent income. The more predictable the income, the stronger the application.

Personal contribution

The contribution represents the amount the borrower is able to invest in the project. Banks generally expect at least enough to cover additional costs such as notary fees, guarantees, and application fees, typically around 8 to 10% of the property value. A higher contribution is a strong positive signal, as it reduces the bank’s risk and can lead to better financing conditions.

Account management

This aspect is often underestimated. Banks review recent bank statements to assess financial behavior. Frequent overdrafts, excessive spending, consumer loans, or payment incidents are all negative signals. Conversely, stable and disciplined account management strengthens the credibility of the application.

Remaining income

Beyond the debt ratio, banks evaluate what remains after all expenses are paid. This “remaining income” must be sufficient to cover daily living costs such as food, transportation, and leisure. The required level varies depending on household composition, whether it is a single person, a couple, or a family.

Overall project consistency

Finally, banks assess the overall logic of the project. Is the property price aligned with the market? Does the project match the borrower’s profile? For rental investments, profitability and rental potential are also considered. A well-structured and realistic project builds confidence and facilitates approval. These criteria are not assessed in isolation but as a whole. A weaker aspect can be offset by stronger elements, which is why presenting a balanced and coherent application is essential.

📊 APR: understanding the true cost of credit

When comparing mortgage offers, the interest rate alone is not enough. The key indicator to analyze is the APR (Annual Percentage Rate), as it reflects the total cost of the loan.

The APR represents the annual percentage that includes all costs associated with the loan. It provides a standardized and comprehensive view of financing costs, making it easier to compare different offers, even if their fee structures vary.

Unlike the nominal interest rate, the APR includes several components: the interest rate itself, borrower insurance in most cases, application fees, guarantee costs such as mortgages or sureties, and certain mandatory additional costs related to the loan. This aggregation provides a realistic view of the total cost borne by the borrower over the entire loan term.

In practice, two loans with similar nominal rates can have very different total costs once all fees are included. The APR helps avoid this bias. An offer with a slightly higher rate may ultimately be more advantageous if its additional costs are lower.

It is also important to note that the APR is regulated and cannot exceed a certain threshold known as the usury rate. This cap is set periodically and aims to protect borrowers from excessively expensive financing conditions.

🤝 The role of a mortgage broker

Working with a mortgage broker can be particularly valuable when aiming to optimize financing without spending significant time on the process. The broker acts as an intermediary between the borrower and banks, structuring the application and presenting it effectively to the most relevant institutions. Thanks to their market knowledge and understanding of each bank’s criteria, they can direct the application toward lenders most likely to approve it.

Beyond this, brokers bring real value in negotiation. By regularly providing business to banks, they can often secure better conditions than those available directly, whether in terms of interest rates, fees, or repayment flexibility. Over the lifetime of a mortgage, these improvements can translate into meaningful financial savings.

Using a broker also simplifies the entire process. Instead of contacting multiple banks, comparing offers, and managing exchanges, the borrower relies on the broker to centralize these steps. This saves time and helps avoid mistakes or inconsistencies in the application.

However, this service comes at a cost, which should be factored into the overall project. Fees may be paid by the borrower or partially covered by a commission from the bank. In all cases, transparency around these costs is essential to assess their relevance.

While not always necessary, a broker can make a significant difference for more complex projects or when optimization is a priority. For simpler profiles with stable income and a strong application, it is still possible to secure good conditions by approaching banks directly.

⚠️ Mistakes to avoid

In a real estate project, certain mistakes can weaken an application or lead to less favorable financing conditions. Most of them can be avoided with proper anticipation and a clear understanding of bank expectations.

One of the most common mistakes is overestimating borrowing capacity. Relying solely on what the bank is willing to lend, without considering daily expenses or unexpected costs, can lead to financial strain. A project must remain sustainable over time, even in the event of changes in income or expenses.

Another frequent mistake is overlooking borrower insurance. It represents a significant portion of the total loan cost, and simply accepting the bank’s offer without comparing alternatives can result in unnecessary expenses. Taking the time to explore different options often allows for optimization without compromising coverage.

Account management in the months leading up to the application is also critical. Repeated overdrafts, impulsive spending, or taking out consumer loans can significantly damage the perception of the application. On the other hand, stable and controlled financial behavior reassures the bank and strengthens credibility.

Focusing solely on the interest rate is another common pitfall. An attractive rate can hide high additional costs or less flexible terms. The overall cost of the loan, particularly through the APR, should always be considered for an informed decision.

Finally, a lack of preparation in building the application can delay or even jeopardize approval. Incomplete, inconsistent, or poorly presented documents create a negative impression and may raise concerns. A clear, structured, and coherent application is essential to maximize approval chances.

📌 Conclusion

Securing a mortgage is not solely about income level, but about achieving the right balance between financial situation, banking behavior, and project consistency. Understanding how credit works, being able to interpret key indicators such as the APR, and anticipating bank expectations allow borrowers to approach this step with greater clarity and control.

A well-prepared application, disciplined financial management in advance, and a realistic view of borrowing capacity often make the difference. Conversely, certain mistakes can quickly weaken a project, even with a strong profile.

In a context where access to credit conditions can evolve rapidly, taking the time to properly structure financing is essential. Whether handled directly or with professional support, the objective remains the same: to secure a real estate project under conditions that are sustainable, optimized, and aligned with one’s situation.
