I think I once read that there are probably loans with lower interest rates for civil servants?
Yes and no, there are professions that offer the bank more security than others.
Your financing is calculated based on your equity, your property, and your financial and professional status. Accordingly, the interest rate is determined as well as special requests such as extra repayments... You are classified as a risky or safe customer. If you have more (money/security), you get more
The "civil servant loan" is called that because civil servants are the safest customers. This also includes employees in the public sector as well as long-time loyal employees of large companies. You will notice this - I think - in the conditions, but it would not say "civil servant loan." If that were the case... wow... taking advantage is punishable... we know that from political scandals
I find your bank conversation... or what it was, somewhat strange. Normally, your financial status is determined to find out how much money you have available for a property. Then you can weigh whether to save more or to look. At least based on the data you provided (salary and so on). Or you have interest in a specific property and then go to the bank to see if you can afford it. Your bank person now comes at you with a big calculation, doesn't advise on annuity loans, and in the end, everything looks different later. Pick a property from the internet and have it calculated for you. But also calculate investments that need to be made before moving in as well as additional purchase costs (notary, land registry, appraiser!). Consultations of this kind should be free at a bank!
