🏠 Property Gain with PPR Relief — main residence / buy-to-let
Private Residence Relief (PPR)If a property was your main home for part of its ownership, PPR exempts the gain during those periods. The final 9 months of ownership always qualify (reduced from 18 months). Letting relief (up to £40,000) may also apply if the property was let during periods of absence.
