Similar problem that I had when I separated from my ex. Had to sell up to pay her off now can’t afford the prices round here.
Made enquiries about a mortgage and was told I would need around a £30k deposit and may still not get a mortgage, dispite the fact I’m paying more in rent than I would a mortgage!
As for council housing, forget it, unless you are the parent in care, which is usually the mother a LA is only responsible for the parent in care.
On the plus side at least my son can stay with me whenever I like, at least my ex didn’t withhold those rights to me, stay with the positives, it’s only money.
