1. Focusing on Interest Rate Alone
This is the most common mistake. Many borrowers chase the lowest interest rate without understanding the implications of indexation tracks. A low initial interest rate in an index-linked track may prove very expensive down the road when the principal inflates and monthly payments skyrocket. The right mix is more important than a specific interest rate.
2. Blind Loyalty to Your Bank
"I've been with this bank since age 16, they'll surely give me a good deal." Wrong! The bank is a business whose goal is to maximize profits. A captive customer is the ideal customer for the bank. You must conduct a comprehensive market survey among all banks and negotiate. Often, a competing bank will offer significantly better terms to recruit you as new customers.
3. Ignoring Future Changes
Mortgages are taken for 20 or 30 years. Will your income and expenses remain the same? Family expansion, education expenses, or career changes must be taken into account. Proper planning must include "exit points" and flexibility for changes, an option sometimes forgotten when refinancing and improving terms or taking a new mortgage.
4. Not Addressing Associated Costs
Life insurance, property insurance, file opening fees, appraisals, attorney fees... all of these add up to significant amounts. Sometimes the monthly payment seems reasonable, but with the addition of insurance it becomes financially strangling. It's important to calculate the "total monthly payment" and not just the payment to the bank.
5. Giving Up Professional Consulting
Relying on the bank clerk as an advisor is an inherent conflict of interest. The bank clerk looks out for the bank, a private mortgage consultant looks out for you. The savings achieved through building the right mix and professional negotiation exceed the cost of the consulting itself by tens of times.
