PBSA mortgage

Purpose Built Student Accommodation (PBSA) is the term commonly used for student halls or buildings designed to accommodate students exclusively or predominantly. PBSA can include student apartment blocks with extensive shared facilities such as a gym, games room, communal areas, on-site management, concierge services, high-speed WIFI, and study spaces. PBSA developments come in a wide range of configurations, and some modern PBSA complex developments now incorporate mixed-use elements, including sections operated as serviced accommodation or short-stay units.

While PBSA properties are not HMOs by classification, in certain circumstances it is possible to secure HMO mortgage products where the property is residential by facilities and configuration. Larger schemes, particularly those including gyms, commercial amenities, or income-generating common areas, are typically more suitable for commercial mortgage lending. A PBSA mortgage may be used for both purchase and re-mortgage, subject to lender criteria, valuation methodology, and planning use.

PBSA (Purpose-Built Student Accommodation) mortgages are a prime example of lending on sui generis property types, a class of its own financial product within the UK property finance market. This uniqueness arises from the specific purpose of PBSA mortgages, which is to finance assets designed expressly for student housing investment. Commercial mortgage lenders can often lend on mixed-use PBSA buildings, where part of the building may be commercial, ancillary retail, or serviced accommodation, provided income streams and planning use are clearly defined.

In the UK, Purpose Built Student Accommodation (PBSA) typically falls under the Sui Generis use class. Sui Generis, Latin for “of its own kind”, is used within the UK planning system to categorise property uses that do not fall within the standard use classes under the Town and Country Planning (Use Classes) Order 1987 (as amended). That said, local planning authority interpretation, site-specific permissions, and development characteristics can create variations or exceptions, particularly where PBSA schemes include commercial units, gyms, cafés, or other amenities, all of which may require additional planning and lending considerations.

When PBSA is located within a high-rise building, securing lending becomes a specialist exercise. High-rise PBSA schemes are often privately owned, with individual units rarely traded on the open market, making traditional residential mortgage solutions unsuitable. PBSA mortgage lenders and HMO mortgage lenders operating in this niche will typically require enhanced due diligence, including a valid EWS1 form. A satisfactory EWS1 report is critical to confirm external wall system and cladding safety compliance, and without it, lending options may be severely restricted.

In addition, borrowers may require a commercial investment HMO valuation, incorporating a yield-based valuation method. As PBSA is a commercial asset class, a residential comparable valuation or basic hybrid valuation may not be appropriate. Commercial valuers will often assess net operating income, stabilised yield, occupancy levels, rental sustainability, and management quality when determining value for PBSA mortgage affordability and loan-to-value (LTV) purposes.

Our specialist team is experienced in structuring PBSA mortgages, navigating sui generis lending, advising on valuation strategy, and sourcing finance from active PBSA lenders, commercial mortgage lenders, and select HMO mortgage lenders. We ensure all required documentation, such as planning use confirmation, HMO licensing position (where applicable), EWS1 certification, and yield-based valuations, is aligned to deliver compliant, competitive, and fundable PBSA finance solutions.
