Reservation-to-Exchange Conversion refers to the interval between a purchaser placing a reservation on a development property and the formal exchange of contracts. This period is crucial in property development finance UK as it directly affects cash flow timing, funding requirements, and project planning. Developers use this metric to anticipate incoming deposits, manage bridging or development loans, and align financing schedules with construction milestones. Understanding Reservation-to-Exchange Conversion allows property professionals to optimise capital deployment, reduce financing costs, and maintain operational efficiency, making it a vital consideration in planning and executing UK property development projects.
