Under the Landlord and Tenant Act 1987, long-tern tenants in a residential property often have the right to buy the freehold to their property if the current owner subsequently decides to sell. This is known as pre-emption right. This guide provides concise advice on what these rights are and how landlords and property managers should most sensibly plan sales, aquisitions and developments in the light of this knowledge. In particular, the book examines the wealth of cases that have shaped the law since it came into force, and highlights the specific problems associated with mixed use buildings.
