Need to buy wife out

AJ2608

Hi, here's the deal.

Split up with wife and looking to get £30,000 to buy her out. The house is a shared ownership house with Orbit and we have £45,000 left on the mortgage where we own 40% Total value of house is around £300k

I'm living in the marital home and she's in agreement that I can buy her out.

However, we're in a debt management plan so my credit rating is ok but not great. I'm also 3 months in arrears with the mortgage which I will be repaying monthly.

I intend to go to a mortgage broker to see what my options are. I can afford to live there although i would take in a lodger.

There is the option of securing the extended mortgage on my parents home (all paid up and their house is worth £300k)

What do you think my options and chances are?

Thank you
