I have a new mortgage through the right to buy from the council. I now want to rent out my property which the council allows, my mortgage company says I have to find a tenant first and send a copy of the tenancy agreement to them before they can give me an answer to weather I am allowed to rent the property out. It’s a residential mortgage and not a buy to let. Has anyone had experience with this before or is this common? Does this mean I have to get the Tennant to sign the agreement and let him know theres a possibility he might not be allowed to let the flat ??
