I'm buying a house that runs on its own gas tank rather than mains gas. We've just had the Fixtures & Fittings form from the sellers and he has said that the remaining liquid gas in the tank is excluded from the cost of sale, and he wants a further £500 for the remaining half tank.
Is this normal? I've only ever bought places on mains gas before so not experienced it. I'm happy to pay it in principle but not if I'm being taken for a ride! Also have no proof of how much is actually in the tank and what that cost would be. Would I be unreasonable to ask for a photo of the gauge and a copy of his last bill to refill the tank?
TIA.
