In the UK, homeowners who purchase their property through the Right to Buy scheme generally have to wait a certain period before they can remortgage. This is typically around 3 to 5 years, depending on the terms of the original mortgage and the specific conditions laid out in the Right to Buy scheme. This waiting period is important as it relates to the discount repayment period, during which selling or remortgaging the property might require you to repay some or all of the discount you received.
