Council Tax (New Valuation Lists for England) Bill

The right hon. Gentleman was talking about houses that had changed hands or been improved, but there is the significant problem of, for example, an elderly lady living in Rose cottage in a desirable village in my constituency. She has never improved her house and never received any income, yet the price of her property would be hugely inflated over time simply because people with London salaries like the idea of living in Rose cottage in my constituency and are prepared to pay a large amount of money for an unimproved cottage. Is there an answer to that in the council tax framework?
