I think that before housing benefit is paid on any property, there should be a certificate of safety and suitability issued by the local authority, and central government should fund local authorities to do this inspection. Too often we see and read reports of disgusting properties with broken toilets/damp/shared kitchens etc, and we, the tax payers, are handing over thousands of pounds per year to these rogue landlords. I would also like to see local authorities able to borrow money at historically low rates as they are now, and build homes for long term rental, thus giving families security and the ability to put down roots, decorate the home as they wish, plant out gardens etc. Not only is this beneficial to children, going to the same school for a few years, making local friends etc., it stops the ghetto effect which can come about in areas where the majority of properties are short term rentals with the ensuing lack of interest in planting gardens, maintaining exteriors, etc.
As I understand it, the 'affordable properties' part of a new development has changed. At one time, in return for granting planning permission or selling land at a below market price, the local authority was granted a percentage of the new build homes to assign to people on their waiting list, not a bad system in fairness. But, Cameron changed this, and the provision of a certain percentage of properties available on 'help to buy' was deemed to be provision of affordable homes.
