MIL is now full time in a care home with moderate to severe dementia. DH wanted to rent out her house to pay the fees but as it's a assisted living house she can't sublet. However if he sells the house it will no longer be exempt for inheritance tax purposes (her estate is about £650k). She has enough savings to pay her fees (house is worth about £200k) but obviously the house is currently unoccupied and being 45 mins away is a pain to visit every 30 days for house insurance purposes.
If he sold the house and bought another he could rent out to assist with her fees presumably because she'd never lived in it, it wouldn't be inheritance tax exempt?
She was always so keen to avoid inheritance tax when she was fully cognisant (ex accountant) but no one forsaw the issue with the subletting (she bought it when she was fully cognisant) or the fact she'd need full-time care outside her home (alarms etc she thought that was all she'd need till she died).
What would you recommend DH does for the best?
