I'm someone who prefers to rent. Much, much better for me, suits my lifestyle, budget and particular life stage.
I just wish that renting didn't have such a bad name in the UK, in many other countries it's a perfectly normal choice.
We bought properties when I was younger, and married with small children. Went along with the "security, it's an investment, don't throw money away on someone else's mortgage" idea. Hated it. Always worrying about the mortgage payments, every time something went wrong (storm, chimney fell off, water leaks, plumbing problems) it was always down to us to sort out. Also, we could only buy in areas we could afford to, not live in the sort of house which would have been more beneficial to us and our children. It didn't seem much of an investment then, high mortgage payments just seemed to be propping up inflated bankers' salaries.
After my divorce I resolved never to buy again. I have never regretted my choice. I would rather keep my money to spend on what I want. I consider my rent to be money spent on providing a roof over my head; to my mind that's what I earn it for.
I have lived in all sorts of beautiful places which I could never have afforded to - even, at one point, the wing of a country house. It was beautiful and worth every penny I spent, every month, for 7 years.
Renting, I'm not responsible for the fabric of the building. Most of the rentals I've had I've been free to decorate, re-carpet or do the garden as I wish....these places do exist (although possibly not in London?)
If I want to move, it's easy, I don't have to go through all the selling/marketing/exchange stuff, I just give notice and go. All the places I've rented have been secure and long-term.
I don't worry about retirement...I am retired now. Been in this place 5 years and expect to stay here - unless I change my mind, of course. There are plenty of beautiful rentable places which carry a lower rental price for over 60 year olds anyway, so I can afford to live here on my state pension. (And yes, it's private not HA, lovely converted country house with grounds, quite idyllic). I'm not worried about when I get senile/die....no-one will have the problem of selling a property like my sister and I did when our mother died....it was a nightmare.
I personally have fewer worries renting than I would if I were in a house I owned. Absolutely love it.
