I am another one who doesn't like having a mortgage and who happily rents.
When I was young and first married, we bought our first and second homes. It was a nightmare. Huge mortgages, never enough money, fears about upkeep which was all down to us (eg. when the chimney blew off in a storm, damaging the roof, there was no landlord to come along and sort it out).
I realised all our money was tied up in the property, we couldn't just give notice and move when we wanted, nor could we afford to buy the type of property in the area we wanted to as it was too expensive.
After my divorce I decided never to buy again. I haven't regretted it at all. I have rented some super places, in beautiful locations for affordable rent which I could never have bought, it would have been too great a mortgage. However, I have always taken on "stable" rentals, places which are for long-term living, not someone's property they're letting while going abroad for a year or two. In addition, I have always rented places where the landlord is happy for me to redecorate or make changes to the property or garden....
I am now facing retirement and quite happy to rent during my retired years. I have recently taken on a pretty place in the countryside which I can stay in until I die or decide to give up the tenancy and move on. The rent is very cheap and I don't worry about upkeep. All my money is mine, not tied up in a property so I don't worry about having money in old age either. I can't see the problem.
We British are obsessed with owning property, some of it came from the Thatcher years, the drive to buy a home intensified then. In other European countries, including France, it is fairly normal to rent and owning your own home isn't such a big thing.
