Put forward your argument that you need £160k from the equity then.
Sounds like he is desperate to sell.
Don't agree a sale though until the agreement is sorted. If it ends up that the money is held by solicitors while you argue over the division for a long time you could end up having to rent for ages and then struggling if prices rise.
Yes this is what i think he is hoping for, that the money gets held by the solicitor and i end up renting.
We have already agreed a minimum sale price, its currently on the market.
Thank you very much for you support and advice.
