Despite the tax rises imposed on the private rental sector, it seems property will remain a safe long-term investment for the 2 million or so buy-to-let landlords in Britain. 59% of landlords surveyed by Knight Knox, are still confident in renting out property as a source of income, and just 11% of landlords have lost confidence in buy-to-let. Close to six million properties in the UK are now in the private rented sector, with this expected to rise to 7.2 million by 2025, or a quarter of all homes.
