Bellway Homes allows buyers to pay just 75% of the property's market value on homes up to £210,000, while Linden Homes initially charges just 80% of the deal. The scheme is a risk because the buyer will pay the remaining proportion based on the market value of the property when it is sold. Therefore, if a property doubles in price to £200,000, the owner would pay £50,000 to Bellways, rather than £25,000.
