Dros ryw ddeng mlynedd ar hugain, mae’r Hawl i Brynu a’r Hawl i Gaffael wedi caniatáu i lawer o denantiaid brynu eu cartref oddi wrth yr Awdurdod Lleol neu’r Gymdeithas Dai.  O ganlyniad, mae llawer iawn o dai cyhoeddus wedi’u trosglwyddo i ddwylo preifat.  Mae’r mwyafrif yn byw yn y cartrefi y maen nhw’n eu prynu ond mae rhai cartrefi wedi cyrraedd y sector rhentu preifat.  Er bod y nifer sy’n cael eu gwerthu wedi gostwng yn ddiweddar, mae cartrefi’n dal i gael eu gwerthu ac o’r herwydd, mae llai ar gael i’w rhentu i’r rheini sy’n ennill incwm bach.  Mae ein stoc o dai cymdeithasol o dan bwysau aruthrol, gan effeithio ar allu pobl i gael hyd i gartref y maen nhw’n gallu ei fforddio ac ar ein gallu ni i’w helpu.
Over the last thirty years or so, the Right to Buy and Right to Acquire have allowed many tenants to buy their homes from their Local Authority or Housing Association. As a result, a very significant number of publicly-funded homes have passed into private ownership. The majority are owner-occupied but some have found their way into the private rented sector.  Although the number of sales has fallen in recent years, sales continue to be made and, as a result, fewer homes are available for those on lower incomes to rent. Our current social housing stock is under considerable pressure and this is affecting people’s ability to find a home they can afford and our ability to help them.
