Okay, thanks for that 44brendan. My fear in waiting was that the build up of equity in my home over the next number of years may induce the UB to attempt a force of sale/bankcruptcy. So wasn't sure wether in the long run it would be better to attempt to draw a line under things now with bankcruptcy while the equity is low. And also it would lift the stress of the debt. But would be fearfull for my kids of losing the family home.
I do understand there would be no gain at present for UB as the value of the house and the Morgage balance are on a par. Thanks for your advice 44brendan, it's much appreciated.
