Hi jane and welcome to the forum
I am afraid that you are caught in the negative equity trap caused by irresponsible secured lending. Who on earth would lend 120% on a mortgage and then lend behind that on a secured basis? Bizarre!
If the secured loan company will not agree to move the loan to the cheaper property, and I can understand why as they will have little or no security, then your solicitor cannot give good title as they will not agree to remove their charge.
Your solicitor is probably best placed to advise here, but practically what I would do is sit tight in the property and try to continue to pay the first mortgage. In the event that the secured loan company take possession proceedings against you, then this will likely result in a sale of the property leaving a unsecured shortfall which will have to be taken into account within your proposed IVA.
In the meantime, you have the benefit of only paying one mortgage - which may equate to the rent you were intending to pay on the rented property. Can you afford to pay the current mortgage and make some form of contribution to the secured lender, whilst also paying IVA payments?
In the event that the house is repossessed and you are eventually evicted, you will probably stand a better chance of getting assisted housing, than if you just handed over the keys on a voluntary basis - but do speak to your local authority about this directly.
Do make sure that you write to the secured loan company to explain the steps you are taking, and invite them to give you any advice they can about the way forward. Keep copies of all letters and other correspondence with them.
