Freshwater are Leaseholders
Freshwater or rather one of the group companies may be the head lessor.
1: Nina look at sglacy posts on leasehold valuations:
2:Read the lease and see if the person who granted you the lease has a freehold or leasehold title, or go to HMLR on line to get office copy entries for your flat.
3: I agree with Jeffrey, if you are at all unsure, bite the bullet, contact RICS.org and find a local surveyor to act on this, Freshwater are tough operators. It's worth the extra.
Based on the information posted, I offer my thoughts.Any action you then take is your liability. While commending individual effort, there is no substitute for a thorough review of documents and facts by paid for professional advisers. More ramblings atleaseholdpropertymanager.blogspot.com
