Online calculation to estimate the cost of an individual lease extension of a flat, or the freehold of a house.
This automated model is designed by Marr-Johnson & Stevens LLP.
This calculator is not designed to give anything more than general advice, and Marr-Johnson & Stevens cannot be held liable for any dependence upon this automated calculation. The circumstances of every leasehold property are different and you should not rely on the information as a substitute for proper expert advice. The calculator should only be used for calculating the cost of acquiring the freehold of a single house or a lease extension of a single flat. It cannot be used for calculating the cost of a collective enfranchisement of a block of flats. The calculation does not allow for Stamp Duty Land Tax or other transaction costs. If you have any doubts about the valuation, please contact Marr-Johnson & Stevens.
