I've only managed to find stable employment later on in life and could not guarantee that I would be alive/working in the same job/earning the same amount of money for 25 years plus.
It's a little gutting that a considerable amount of the house's value is also interest to the bank, and that you only own it for comparitively few years before you have to sell it again to fund someone to wipe your bum later on in life.
Not all landlords are BTL bastards who are willing to kick out tenants at a whim. My last 3 have been absolutely brilliant and I love the flexibility renting brings if I want to move after a month.
I also deeply resent people saying that renters don't really have a home. As long as we pay the rent, it is in our possession legally until we reliquish that responsibility via surrendering the tenancy. As an owner, you may be constantly thinking about the value of your 'home' and you are constantly oscillating between it being your 'forever home' or selling it to make a profit. Commodity or home? I guess some people can live with both...
Currently having extensive repairs on a 200 yard fence boundary that my current landlord is repairing. I don't have to pay, neither did I have to pay when I had to have dangerous mature trees taken down in my garden, new boiler, annual servicing, plumbing repairs, etc.
In addition to all this, I can decorate my home any way I want to. Granted, I leave the place tidy, fill in picture holes, take down shelving etc, but don't you have to do that if you are a homeowner wanting to sell?
Finally, I do have a pension and am starting a small private one in addition so yes, there is provision when I retire at the age of 85....
