Hefty, Mum and Dad had lived in council housing for many years. Under the right to buy, you were 'given' a percentage of the property for rent paid. So they were given 49%, and mortgaged 51% with a building society.
In those days women, if married, couldn't have a mortgage alone, but my Dad was an alcoholic who saw buying the house as losing drinking money...but he had to be on the mortgage. My brother put his name down to ensure the mortgage. From 82-86 he paid the mortgage, instead of house keeping. So Mum paid all utilities, fed him, did his laundry, ironed and put him up most weekends. In Nov. 85 he moved to a job in London, and stopped paying the mortgage in Jan/Feb the following year due to financial difficulties. In 1992, after marrying a Finnish resident he asked for his name to be removed from the register and after that my Mum was sole owner as my Dad dies in 1989.
