It costs whatever you can afford. You can make your own arrangements with the home of your choice and pay all the costs yourself. Or you can talk it all through with us and we will advise you.
If you own your own home and no-one else lives there you will have to try to sell it eventually.
There is no need to rush into selling your home until you are settled and have no need to keep it for yourself.
If you have a lot of other savings these may affect what you pay as well but do talk it over with us. We are here to help you sort out these things.
