Search for real estate loan advantages/disadvantages insurance vs bank

There are insurances that offer extremely low interest rates, while local cooperative banks charge double the interest rate. Why is that so?

Especially the cooperative bank can currently make you an unbeatable offer. There is a promotion running through a real estate bank of the association with a 0.25% discount on the otherwise normal conditions. There can only have been an error in setting the conditions. Property value actually just under a million?

Advantages and disadvantages if I finance through an insurance company.

None

Especially since one does not finance through an insurance, but the lender is an insurance company. They offer a classic annuity loan. An insurance is not necessary, but I think that is clear enough. What does surprise me, however, is the fact that we are discussing €500,000 fixed for 10 years. At an interest rate of 0.88%, which is even cheaper with a 10-year fixed rate at an assumed loan-to-value ratio of less than 60%, this corresponds to an outstanding debt of around €445,000 with a repayment rate of 2%.

You miscalculated by €50,000.

You miscalculated by €50,000.

Yes, of course, that's right, I foolishly calculated with 1%. But even €400,000 remaining debt doesn't change the core statement or surprise.

What is your actual mortgage lending value, or purchase price/manufacturing cost and equity investment?

It is an inheritance case. Payout to the sister. That means the market value is probably >1 million if he needs 500K€. Therefore, loan-to-value is 50%.
