Government grants and schemes do have an effect on the market. The main objective of these grants is to help you own a home. However, when grants are introduced, the demand for a certain range of houses shoots up, and as a result, prices rise as well.\r\rHaving said this, getting a grant or qualifying for a scheme can aid you significantly on your purchase. On top of that, if you can qualify for a grant/scheme early, before the market has had a chance to move, the rising prices will increase your equity in your home.
