Proof of funding

[JohnCRaven]

My friend's buyer is dragging his feet and he suspects his offer was based on getting a top up mortgage rather than the cash buyer he initially presented as.

Is he able to ask for proof of funding for the sale and what detail would it go into? % mortgage %cash or amount mortgage amount cash? His estate agent is useless now the price has been agreed.

I've posted this in Property hoping for advice rather than opinion but realise this is a legal matter.

Every estate agent I've ever bought with has requested proof of funds before they'll take the property off the market. I'd check with them that this happened first!

The problem is the estate agent is useless and my friend wants to see the proof for himself because he doesn't think the buyer or the estate agent are capable of being truthful.
