Sorry to hear you've not been approved. Fair play to you for trying to move forward in such a positive way. WRT renting the house you want to buy, I don't see that you have anything to lose by approaching the vendor. I think the answer probably depends on the current circumstances of the vendor i.e. do they have to sell to generate income to move on to another house? Rental income rather than the proceeds of a sale might not be enough for them to do this. Also the interest the house is generating in the market. If they sign a lease with you, then they will have to reject other potential buyers. Then again, they may not have had any interest in the house and will jump at the chance to rent. But certainly, as I said, whatever the case you have nothing to lose by asking. And it would be great to 'test drive' the house. I'd say lots of people wish they'd had the opportunity to do that. Whatever happens, it sounds like another year of proved savings might sway the bank in their decision. I wish you well with your health and the house in the future.
