Hi
To be honest, Bank's dont really want to have to provide bridging, full stop. The ones who do, will tend to only do it for existing customers, who are putting their mortgage business with the same bank ... so providing a decent future income stream etc.
Regardless of what you read in the papers, written by various well regarded journalists (I think that that lady in the Sunday Business Post, Aileen (Power ?) recently suggested you should tell a bank to shag off, if they look for arrangement fees) ...the reality of the situation is this is quite often you will have to pay fees if you want bridging.
Take it or leave it I guess ... but as mentioned already, the real way to deal with this is put pressure on the purchasers of your house to complete quicker !
cheers
