I hope I've understood you correctly.....you own your own house now. Its too large for you so you want to sell your own property and hope to move into council property.....presumebly you will pocket the proceeds of your house.....yes?
Personally I would be amazed if any council will wear that situation val.
Surely the thing to do is sell your property by all means, and use the proceeds to puchase a retirement property of your own.
We did this last year. Having had a 3 bed house that became to big to care for as we used to, we sold it and downsized to 2 bed retirement property. Made a few �s as well.
IMO thats the way to go.
