Hang on senacca. The house in question for example is worth more than yours but is in the same price value bracket. Would you take £100k plus a loan that still leaves part of your new home owned by someone else? Think not.
For the misery caused and the legal fees that will be incurred out of our tax the best solution is simply to pay the good lady what she asks.
If I'd been stupid enough to get into that situation: buying a house and spending lots of money on it-this is quite clkear by looking at it, in an area that had been dying for years and was getting worse in front of my eyes, I'd be glad of the second chance.
