PBSA investment and yields explained

PBSA investment means buying, building or funding purpose-built student accommodation to earn rental income from students, and often a capital gain on sale. Most blocks are owned by institutional investors, funds and specialist operators, while private investors more often reach the sector through listed property companies, funds or individual rooms sold by developers.

Purpose-built student accommodation is designed for students from the start, with private bedrooms or studios, shared kitchens or communal areas, and on-site management. It sits apart from student houses in multiple occupation, which are ordinary homes let to groups of students and financed on buy-to-let terms.

A PBSA yield compares a block's annual income with its value or purchase price. The gross yield uses the total rent before costs, while the net initial yield, which valuers and investors use most, takes the rent after operating costs and divides it by the value. A lower yield means a higher price relative to income.

Published PBSA yields come from agents' and valuers' market reports, and they change with interest rates, investor demand and the location of the block. Any yield quoted for the sector should carry the date and source of the report it comes from, because figures move from one quarter to the next.

This worked example uses example figures, not market data, to show how a net initial yield is set for a block. They assume a block of 400 beds let at £180 a week for a 51-week tenancy, with operating costs of 35% of rent and a value of £40,000,000, which gives the result set out in the next paragraph.

In the worked example, with example figures, not market data, the gross rent is 400 x £180 x 51 = £3,672,000 a year. Removing operating costs of 35% leaves net income of £2,386,800. Dividing that by the £40,000,000 value gives a net initial yield of about 5.97%. A lower value for the same income would raise the yield, and higher costs would lower it.

Valuers usually value an operating PBSA block on its income, applying a yield to the net rent, and they follow the RICS valuation standards. They look at occupancy over recent academic years, achieved rents against nearby blocks, operating costs, the length of tenancies, the condition of the building and the strength of local student demand.

Location relative to universities and transport carries weight, as does the balance between the number of full-time students and the beds available in the city. Blocks in cities with strong university demand and few new beds planned tend to be valued more highly than those in markets with plenty of new supply.

PBSA blocks are let in two main ways. Under a direct-let model, the operator markets rooms to students and sets the rents each year. Under a nomination agreement, a university agrees to fill some or all of the rooms for a set number of years, which gives steadier income but usually at lower rents.

Some blocks combine both, with part of the beds under nomination and the rest let directly. Lenders and valuers look closely at the length and terms of any nomination agreement, the university's standing, and the operator's record of filling rooms on a direct-let basis.

Investors buying a completed block usually use an investment loan secured on the property, sized against its value and the net income. Lenders look at interest cover, occupancy history, the operator and the building's condition, and they may set covenants that require occupancy or income to stay above agreed levels during the loan.

Developers building new blocks use development finance first, then refinance or sell once lettings are established. How that build funding works is explained on the student accommodation development finance page.

Buying individual rooms in a block sold off-plan to private investors carries different risks from owning a whole block, including limited resale markets and reliance on the developer's management, and few mainstream lenders offer mortgages on single student rooms.

PBSA income depends on student numbers, which can change with university admissions, international student policy and competition from new blocks. A city with a large pipeline of new beds can see rents and occupancy come under pressure, so investors and lenders look at planned supply as well as current demand when they assess a block.

Operating costs, from staff and utilities to repairs, can rise faster than rents, which reduces net income and the yield. Building safety work, changes to planning rules and the end of a nomination agreement are other risks that investors and lenders weigh up when pricing a block or setting loan terms.
