Please could you help settle a debate in our household. A leasehold flat in our area sold for a few hundred thousand pounds, nothing surprising. The sale price is accurately recorded online. However, the Land Registry records state the sum of only £6,000. The actual buyer is listed as the sole owner, the freeholder's record is separately listed. It was not a personal sale at below value, they do not know each other, bought via the estate agent in the conventional way with a large mortgage. There is no intermediary/company/trust stated. What could be going on and how could further information be obtained?
