I will simplify the figures.
MIL has been losing her memory for ages but has no diagnosis despite some medical tests. For example she cannot remember plans at all - if you say we are leaving for lunch in half an hour she will almost never remember. Her long term memory is fine.
We live 2 hours away from her and in the last few weeks she has decided she can no longer drive to us. Public transport not an option. She is utterly miserable and scared. We have 2 very young children and can't visit that often.
She finds even very small tasks incredibly stressful. For example sending an email can get her so stressed that she is brought to tears.
We all think it is time she moved to a retirement village near us. In fact we have all been in agreement of this for some time BUT the stress of her selling her current home is too much for her. She simply cannot engage in the process without falling apart (not emotionally but she gets so stressed).
The apartment costs £400k. She has £200k in cash, I have £200k in cash. I am considering loaning her the money (formalised in a document, no interest). DH has total POA (medical and financial) and will then deal with the sale of her house to pay me back. We know she needs to sell within a certain amount of time to avoid CGT.
For the sake of completeness: Mine and DH's finances are joint but this money comes from the recent sale of my flat which was purely in my name as I bought it before meeting him and so we see it as 'mine'. I also earn less than him and like having this nest egg.
Please evaluate this plan as harshly as you like. The £200k we would both use up leaves neither of us destitute!
