what a mess Paul, i do hope you get some sort of acceptable solution here.
In your original post, you say
""The only concern is that it proceeded at under open market value so they can claim the difference.""
How will they prove what THEY think was its market value over a year ago when estate agents assessments always vary by a considerable amount.
You may have had substantial work done to the property in the meantime - how does anyone go about proving the value of that retrospectively ?
