Trying to sell a flat with 68yrs left on the lease and feedback from the agent is that this is putting people off. Need to look into extending the lease but it’s a slightly odd situation in that we as owners of the flat, jointly hold the freehold with the other 16 owners . I’m embarrassed to say I don’t properly understand the system and all the internet advice is talking about negotiating with the freeholder. Any one around who doesn’t mind explaining the set up and pointing me in the right direction?
