Place we're buying has split titles, one for house and another for most of the garden (purchased off farmer in 90s), the garden title has a restricted covenant that basically says we can't legally claim loss of air or light if the farmer builds on his land. This has only come to light a week before exchange, and our lender is Nat West. Is this likely to mean check mate for our mortgage offer (and the whole chain) or is there some chance that either our solicitor will mitigate it in some way when they report to the lender or the lender will take a fair approach? Any thoughts / experiences much appreciated :-)
