I have some experience of this as my Mum bought one when she first separated from my Dad, and also my ex got one when we broke up.
I think they are a really good idea, as a stepping stone, but a few things:-
If it's a flat or maisonette, you will be liable for a maintenance charge and insurance. For Richard my ex the maintenance charge was REALLY high! Especially bearing in mind the communal parts were very basic and there was no garden or parking. And of course with the insurance, as far as I know, he
had to pay it through them, there was no option to shop around for a cheaper deal.
My Mum's bug bear was that her rent went up every year without fail. And she was worried that in the long term she wouldn't be able to afford it. Esp. if she was still there when she retired. (That didn't happen
)
I also think, the values of the properties seem inflated. As an example, a flat could be valued at £160k so a 25% share would be £40k, but in reality, on the open market you would get an equivalent flat for a lot less.
Richard definitely had a cat in his flat. My Mum has always had loads of pets.
The other thing to consider is that you do still need a deposit and your legal fees etc for a shared owndership scheme. And sometimes you also have to pay a premium, I think my Mum's was 10k and that was years ago.
However, on the plus side, I think you would feel much more like you were living in your own place, rather than rented, and you would also benefit from any increase in equity.
For Richard, it got him out of a scummy bedsit and into a brand new flat with appliances and carpets etc, and for my Mum, well years ago there were a lot less options anyway, but it got her a big enough house in a good area for the period she still had kids living at home.
If I were you, I would phone your local council and get an application form sent to you. I did Richard's for him and within 2 months he had an interview. You have nothing to lose by attending an interview and finding out what they can do for you, and how the contract works.
The schemes are normally run by housing associations rather than councils, but where I live, it is the council you go to, to get information.
Hope that helps.
