Franciscrawford I don't imagine Jess needed much supporting by Rob when she was not working during her father's illness as she was living with her parents. When she came to Ambridge I think she had found a new social work job in the area.
As to him not buying a home ten years ago though, if he had been in the US and Canada all that time it is very difficult to get a mortgage from a U.K. Bank when you are not UK-resident, even if you are a U.K. citizen. I know this from personal experience having bought in the U.K when living in Hong Kong. It limits possible lenders to only 1 or 2 and you need a much bigger deposit.
