Some properties do not fit neatly into one category
Converted buildings, including those containing partially self-contained units, may require the title structure, planning position, building regulations, licensing requirements and floorplan to be considered together.
A hybrid property may combine elements of an HMO and an MUFB—for example, three separate flats held under one freehold, with one flat occupied as an HMO. Different lenders may reach different conclusions, so these properties are likely to require a bespoke solution from a specialist lender.
Multi-unit leasehold blocks also require individual assessment, as lender appetite can depend on the title structure, lease arrangements and whether the whole building is being offered as security.
