It belongs to the realm of legends that a home loan must/should not run into retirement and that one constantly has to renovate a house in old age.
My grandma lived in her house until she was 95 and hadn’t renovated it for at least 35 years... that worked without problems. As long as the heating doesn’t fail... a few drafty windows or an old-fashioned bathroom, so what?
Also with the home loan. What is supposed to happen to me if there are still 50,000 EUR left at retirement? The house is worth much more than these 50,000 EUR, so the bank has top security in case of my death... that’s why the bank would also gladly give me a 10-year loan with a monthly rate of 500 EUR at age 67.
And if I don’t have those 500 EUR... then I couldn’t afford a rental apartment either...
PS:
One has to free oneself from the idea of viewing the follow-up financing the same way as the initial financing. In follow-up financing, one is usually much better off because the remaining amount is smaller and the security (equity and value of the house) is much higher.
