Inheritance tax,can anyone please give any advice

[wilko73]

I have been looking after my mother for years as she has dementia which is now advanced,I live in the family home and always have and I'm worried about the future concerning inheritance tax when the time comes to do probate etc as I'm the executor of mum's will ,as I would like to stay in the family home and not have to sell it and I'm hoping not to get a big IHT bill.The house is left to me as the only child as per mums will.I have been looking back at who is mentioned on the deeds and found the home was transferred to my mother in 1995 as that's when my dad became ill with cancer and he must have thought that would put mum on a more secure footing so it must have been just his name on the deeds before that,he died in 1999. I'm now wondering does this effect any IHT rules as I when the time comes I was going to use his nil rate band to add to mums and to take us over the house value so no IHT would be due.He left everything in his estate to mum.
If anyone has any knowledge I would be greatful.
