Could you/would you revise offer?

[Juno213]

We were buying a house from an older lady. It got to day of exchange when the top of the chain pulled out so it all collapsed. Or vendor still wanted to sell, the chain started again and then she got very poorly and got given weeks to live so she pulled out of her purchase. She still wanted to sell and was going to try to move in with family and then sell to us.
We got an email today saying that she has sadly died but that her children still wanted to sell once probate was granted.
If we go ahead we well need to get a new mortgage offer as ours is about to expire. Our broker has said that because of the extended time frame, we should renegotiate the price.

Morally, I don't know that I can do this to someone who has just lost their father but I suppose I don't owe then anything and it is a business transaction.
Could/would you do this?

Depends on which way the market shifts, I suppose. But the house will be valued from the date the parent (mother or father? you changed your mind halfway through) died, and that is the price on which probate and any inheritance tax will be based.

Sorry,so I did. It should say mother. That will teach me to post when I'm up in the middle of the night.

I'd move on. Probate could take a year. Ask then to contact you when ready to sell and if it still suits have it revalued and do a private sale.

- yes, late night posting can be interesting!

I have to agree with munchkin though - probate can take a long time, so it might be best to look elsewhere unless you can wait and absolutely have your heart set on it.
