Ooh, you are a lot of miseries here! There are a lot of positives of not owning a property for a woman on her own at retirement age.
First, no maintenance. Something needs repairing, and it’s the landlord’s problem, not yours. Of course, not all landlords manage their properties well, but plenty do, and if you get a duff landlord, you can walk away at the end of your tenancy.
Second, you aren’t tied to one place. If you don’t like the local area, or you get snotty neighbours (or have a bad landlord, see above) you can just look for somewhere else. Of course, it helps if you have already jettisonned 40+ years of accumulated junk. If you want to sell a house to move and buy somewhere else, it is stressful, takes a long time, and costs a lot.
Third, you know exactly how much you are going to spend each month - rent, council tax, bills - so it’s less complicated to budget. You haven’t got a load of capital tied up in a property, so anything that’s left after the bills are paid is yours to use. No buildings insurance, no liability for keeping the property safe, no emergency plumbers etc, and much less responsibility, so you have the headspace to enjoy life.
And if you’re brave, you can house-share. Despite all the horror stories, there’s a lot to be said for having other people around. There are plenty of house shares where all the residents are older, or you can be the mother hen in a house with younger housemates.
I don’t own a house, and don’t want to. Freedom to move around and no unexpected expensive maintenance are the main reasons. Even if I won millions on the lottery, I still wouldn’t want to buy.
