Living exclusively in rented accommodation in old age - my personal opinion. Why? Own house: ties up capital, constantly costs money (maintenance and renewal) and is labor-intensive. Own apartment: see above, the advantage is that there is always a fixed service charge for the common property, as long as no extraordinary measures are due. Rented: rent is fixed - all other money can be spent on whatever (travel, living expenses, cars, hobbies, etc.). If something breaks in the apartment, I simply call the landlord. What can of course be discussed is the definition ([im Alter]). My mother (68), for example, moved out of her own apartment a year ago and now lives comfortably renting. With the proceeds from the sale, she can live carefree without any restrictions well into old age.
