Park home living

My DH and myself are thinking when we retire of selling up and buying a park home to release a bit of equity . We live in a remote village no transport links and worry when we are not working we will be a bit isolated especially if we couldn't drive
We will only have state pension so it will free up a bit of cash . I know a park home will cost and plus the ground rent but it should free up when our house sells about 100,000 . Anyone done this how's it been . Thank you for any responses
