The document discusses how builders can expand their margins by taking advantage of the UK's Help-to-Buy program. It provides tips for builders, such as actively seeking land with Help-to-Buy provisions, critically assessing profit potential early in the development process, planning for Help-to-Buy from the beginning to allow for greater densities and shorter approval times, and using accurate information systems to reduce costs and boost margins. The document emphasizes that Help-to-Buy represents an opportunity rather than a restriction for builders, and that smart use of information allows builders of all sizes to benefit from the program.
