Every penny spent was on home improvements for this absolute money pit her and her partner bought. So not like she had holidays or plastic surgery and if she didn’t pay it back I could put a charge on the house, but that’s all by the by isn’t it
Who suggested the charge on the house OP?
Surprise me - it was your friend, who thinks she can come to a F&F settlement after a month of IVA talks, who chose to buy a money-pit, seems to either misunderstand or misrepresent her IVA arrangement, & is happy for you to use all YOUR hard-earned savings & put YOU into overdraft?
What do you think will happen when she reneges on paying you back - or fails to cover YOUR 40% interest charge on the overdraft SHE expects you to provide for her?
Will you feel able to enforce your charge against her house, forcing her to sell up? Even if you were to do that (& I'm guessing not, how many of us could, & you are a bit of a soft touch around this friend) - would you expect her to stay friends with you, or blame you for "making her lose her home"?
When you say no - & you must say no, this is a ridiculous scheme - do you expect her to stay friends with you, or is she likely to go all pass-agg offended & drop you?
Either way, you are going to lose a friend.
You may as well choose the option that doesn't also leave you up financial shit creek.
