Norman from start to moving in it can be as little as 16 weeks depending on which flat pack the use. We lost so much social housing in the 1980s with right to buy which was never replaced as local authorities couldn't use the money for new builds only refurbishment. It was why so many local authorities set up almo's(arms length management organisations) so they could build properties, some were very good and some were abysmal. Most have been taken back into local authority control as it takes away a level of administration and save money. Private landlords on the whole charge exorbitant rents compared to local authorities and housing associations and the no fault evictions make it a precarious way to rent. There's thousands of families who would take your hand off for those houses if they were available .
