Neighbour wants to buy house.

Hi

I am mortgage free in a 3 bed semi worth around 460k. I am blessed with a large garden.

Next door was bought last year and a couple have moved in.

He has offered me verbally 500k to sell. I refused as I have my elderly parents here and I would need to find a place suitable for us all (wet rooms, banisters, wide doors etc... ).

As these properties are not in the area for sale I can't just join a chain. I would need some kind of bridging loan.

So I have refused.

Today a solicitor has written to me formally asking to sell before legal avenues are explored.

We have been here nearly 50 years as a family.

Is there any legal avenues or is it just idle threats.

He has also approached neighbours over the back of us. I feel like he wants to knock down around 6 houses and build god knows how many more or apartments.
