DH and I have had offer accepted on house. We are chain free and keen to move. The property has leased solar panels. We have told the vendor we would not want to continue with the sale unless the lease was "bought out". Vendor has agreed with this in principle. He is elderly and very keen to move closer to his daughter who lives abroad therefore wants to conclude things ASAP. He has had a quote for the lease to be bought out which comes to £13k. He wants us to pay half of this (so around £6.5k). This is I suppose where we have a philosophical disagreement. It is my belief that he should be responsible for the entire cost as he decided to take out the lease and if he wants to put the property back on the market and try and find a buyer for the property with the lease in place thats his decision. The main thing it will cost him there of course is time as that may take several months. We could make a contribution towards the lease buyout...DH has suggested £3k. Not trying to cause the vendor more stress but do feel he should have been aware this might be an issue before the sale if he had good advice from EA. The agreed offer on the house was £330k. AIBU here?
