Since the credit crunch started, buying or remortgaging without a deposit or equity is no longer possible. However, there are still a few situations where it is possible to purchase a property without the need for a deposit. Firstly, anyone buying their council home will normally be able to borrow 100% of the full purchase price and secondly, anyone buying from a relative at below full market value, commonly referred to as purchase under value, will also not need a deposit.
