Why can’t they get another mortgage??
Is it because they never bothered to actually make the payments each month & the house was taken off them?
That would not surprise me, as I would imagine the pair of them have direct debits “rejected” non stop, as they squander there wages, no money in there bank to meet the dd’s
Who are they renting the current house from, as she has painted over the dark wood internal doors & fireplace surround white etc. I would not imagine a landlord would let you make changes like that etc
