Lease extension valuation
What your valuer will need from you
You’ll need to give your valuer:
- a copy of your lease and any deeds of variation
- details of ground rent and if it is fixed or how it increases
- the lease start date and remaining term
- evidence of improvements (what was done, when, and by whom)
- any recent mortgage valuation or agent appraisals
- access to the flat for inspection
- local sale evidence of comparable properties
Good documentation helps avoid disputes and speeds up negotiations.
What a good valuation report should include
Ask your valuer to explain:
- all assumptions used (rates, relativity, improvements disregarded)
- a best- and worst-case range and opening offer
- how they’ll present evidence if the case goes to tribunal
