"First time buyers relief ends after year 7. The relief for non-first time buyers will be reduced from 20% to 15%."
The term "First Time Buyer" is really quite misleading I reckon. If you buy a new PPR within e.g. 2 years of buying your first PPR, you are still an FTB (for the remaining 5 years). However, if you buy your first house and don't sell it, you stop being an FTB after year 7, even though you haven't bought another house. I know what they mean, just the term itself implies something about the number of times one buys a house, which is not strictly the case.
