Is it possible to terminate my lease with no penalty, and be refunded the money I paid for the mobile home?

I recently purchased a use mobile home for myself and my three young children. When I viewed the place, I was told that the roof had recently been redone, and that the furnace was in working order. Neither of which turned out to be true. There was new paneling on the walls and mostly new flooring throughout. This was only to hide the existing water damage, not fix it. I was never informed of any of this. I would not have purchased the mobile home had I know the defects. We currently have no heat and it is likely there is mold within the walls.
