The lease was only 99 years when it was built. Was 92 when I bought it. Tbh I didn't know about the pitfalls of leasehold and it was the only way my ex and I could get on the ladder. And yes, I know all about the marriage value etc now, a bit too late mind.
The whole thing is a scam. What really baffles me is the housing association owns the other half so any sale makes them money. Surely if the lease running low creates a loss in value for them, why can't they just grant a lease extension? Obviously there's some ridiculous laws involved somewhere but it's a joke. I could sell it in the very near future I guess but again, I'd have to find somewhere I can afford in this area which isn't easy for a single dad.
I didn't realise shared ownership was a thing back then. But I suppose 1992 was after the mega recession!
Have you asked them for a quote to extend the lease? Or buy the FH? Don't ask, don't get and all that. Whilst it is a bit of a calculation, it is more of an art than a science. Yes you can value an income (the ground rent) quite accurately, but the rest of it is theoretical based on comparables etc. so certainly more of an art - the job of the surveyors involved. I did one years ago for my dad with Peveral being the FH (utter utter you know whats) and I got a reasonable result in the end paying £5k all in (they wanted £15k but messed up and didn't respond to my notice). As they are "in bed" with you, they might treat you differently?
