Nobody can now go back on the deal or change any of the terms.
Generally, houses are freehold. The owner can decide when to repaint, when to repair the roof etc. Obviously, there are some restrictions which the owner will have to accept, as the owner will be responsible to the tenant under the landlord and tenant legislation for maintenance of the exterior, structure, water and central heating, boiler system and sanitary units, as well as keeping the property wind and watertight. By contrast, flats are leasehold. The freeholder will usually be responsible for maintenance of the structure, exterior and common parts etc., and the cost of this together with the cost of managing the block will be recoverable from the Lessees, through the service charge.
