'There really is only two solutions. Build more houses to sell or build more houses to be rented out by the local council with a fixed rent'.................Very much agreed. Once upon a time the councils had the power to cap the rent landlords could charge, that's gone.
What I find abhorrent is working people struggling so much that they are forced to seek help from the council. The council then have the discretion to pay out up to the max amount of LHA. That equates to the tax payer paying the mortgage for a private BTL landlord. Preposterous.
Bit pompous aren't you. The OP has missed the point, empty second homes should be double council taxed. Private landlords should not be able to charge double the mortgage in rent. Plain enough for you now? Pffft
