Choosing a mortgage is one of the most important financial decisions you'll make in your life. Many buyers unknowingly make mistakes that increase the total cost of their loan and affect their long-term finances. At Immosegur, we guide our clients to make informed and secure decisions, and one of the most important aspects is correctly understanding the concepts of APR and Annual Percentage Rate (APR).
One of the most frequent mistakes is focusing solely on the monthly payment without analyzing the total cost. The APR (Annual Percentage Rate) indicates the percentage that the bank applies to the principal it lends. This value is used to calculate the "pure" interest, but it doesn't include other expenses, such as origination fees, mandatory insurance, or linked products. For example, an APR of 2% on a €150,000 loan means paying €3,000 in interest per year, not including fees or insurance. If you only focus on the initial payment based on the nominal interest rate (TIN), you might think it's the cheapest option, but in the long run, it may not be.
The second common mistake is ignoring the Annual Percentage Rate (APR). This figure reflects the true cost of the loan because it includes the nominal interest rate (TIN) and all associated additional expenses, such as insurance, fees, and other linked products. For example, let's consider two mortgages: Mortgage A with a 2.2% nominal interest rate (TIN) and multiple mandatory insurance policies → APR 3.0%. Mortgage B with a 2.5% nominal interest rate (TIN) and only one mandatory insurance policy → APR 2.7%. Although Mortgage A has a lower nominal interest rate (TIN), the actual cost is higher due to the linked products. Failing to analyze the APR is a mistake that can cost you thousands of euros over the life of the loan.
Another common error is not evaluating the loan term. The nominal interest rate (TIN) doesn't change with the loan term, but the APR does. In short-term mortgages, expenses are concentrated over fewer years, increasing the APR, while in long-term loans, they are spread out, reducing their impact, even though the total interest paid is higher. Ignoring this detail can lead to choosing a loan that doesn't fit your repayment capacity.
It's also common not to negotiate fees or review linked products. Life insurance, home insurance, pension plans, or other products required by the bank can significantly increase the APR and, therefore, the true cost of the mortgage. Failing to gather proper information or compare different offers is a mistake that can lead to unnecessary extra costs.
At Immosegur, our goal is to help you avoid all these mistakes. We analyze each mortgage offer, explain the difference between the nominal interest rate (TIN) and the annual percentage rate (APR), and show you how they affect the monthly payment and the total cost of the loan. Furthermore, we teach you how to negotiate fees and choose linked products intelligently, ensuring that the mortgage fits your budget and needs.
