What is a portfolio mortgage?
Portfolio mortgages are designed for landlords who own four or more mortgaged buy-to-let properties. Since 2017, the PRA requires lenders to apply specialist underwriting to portfolio landlords, assessing the performance of the entire portfolio rather than individual properties in isolation.
