The Renters’ Rights Act has changed student lets for good. Here’s what Ground 4A means for landlords, and how a student let mortgage stacks up in 2026
There was a time when the student letting year ran like a train timetable (Japanese train timetable to be precise). Rooms signed up in November for the following September. Twelve-month fixed term. Rent paid termly. Everyone knew where they stood eighteen months out. Happy days and a nice and easy cashflow to keep a student let mortgage lender sitting comfortably.
That timetable has gone. Less Japanese railway to classic UK rail. Since 1 May 2026, when the main provisions of the Renters’ Rights Act came into force in England, fixed-term tenancies no longer exist in the private rented sector. Every assured shorthold tenancy became a rolling monthly tenancy with no end date. Section 21 – the old “no fault” eviction notice – that went with it.
If you own student property, or you’re thinking about buying some, this changes the shape of the deal and the predictable income that went with it. It doesn’t kill it. But it does change what your regular income looks like, and that’s exactly what a student let mortgage lender is looking at when they price their student let mortgage.
The old model was a fixed term. You let a six-bed house to six students from 1st September for twelve months, and short of something going badly wrong, they were there for twelve months and so was the rent.
Now every tenancy is periodic. It rolls month to month. Tenants can give two months’ notice to leave at any point, and in a joint tenancy one tenant’s notice ends the whole thing for everybody. You also can’t take rent in advance before the agreement is signed, and rent periods have to be monthly – so no more termly payments lining up with student loan instalments.
In many practicable ways the changes, designed to protect the tenant, doesn’t really work that way in this sector. That said, it’s here and it is what it is.
I love my sporting analogies, with this one it used to be a season ticket. You knew the fixture list a year out. Now it’s more like buying a ticket for each match as it comes.
Parliament did recognise that student houses are a special case. The replacement is Ground 4A a possession ground that lets a landlord get a student HMO back in time for the next academic year.
An HMO, for anyone who hasn’t had to think about it, is a house in multiple occupation: three or more people from more than one household sharing a kitchen or bathroom. Your standard six-bed student terrace.
Ground 4A works, but only if you’ve done the paperwork properly (there is always a caveat):
Every tenant has to be a full-time higher education student when the tenancy starts. One part-timer in the house and the ground falls away. You have to give the tenants a written statement, before they move in, saying you intend to rely on Ground 4A. The tenancy can’t be signed more than six months before they get the keys – which effectively kills the November sign-up and pushes recruitment into the new year. And you need to serve four months’ notice, on Form 3A, with possession falling between 1 June and 30 September.
Learn that, it matters.
Get it wrong and you’ve missed your window for a whole academic year. Use it without genuinely intending to re-let to students and the civil penalty runs to £40,000, according to the guidance summarised by law firm Trowers & Hamlins.
Think of Ground 4A as a fire escape. It’s there and it works – but you have to have the door clear and the sign on the wall.
Here’s the bit I find myself explaining most often, because it catches people out.
Ground 4A only applies to HMOs. A studio flat let to one student, or a two-bed let to a couple of postgrads, doesn’t qualify. Those sit under the ordinary rules with no student-specific route to possession at all, as Osborne Clarke set out in their analysis. If you’ve built a portfolio of one and two-bed units near a campus, you’re now running them like any other residential let and that may change how, when and whether you let them the same.
Purpose-built student accommodation is different again. Large PBSA blocks can be exempt from the assured tenancy regime altogether – keeping fixed terms and advance rent – provided the operator signs up to a government-specified management code, expected to be the ANUK/Unipol code. That’s a real advantage for block owners, and it’s part of why development finance enquiries for student schemes haven’t dried up.
So there are now three tiers: PBSA with the exemption, student HMOs with Ground 4A, and everything else. Which tier a property sits in affects its income profile, and therefore what you can borrow against it.
Three things, mainly.
Voids get lumpier. Students now leave when their coursework finishes, which for a lot of them is Easter, not June. Councils charge full council tax on an empty property once the student exemption drops away, so an empty May and June costs more than it used to. Lumpier income, cashflow impacted and costs continue.
Income is harder to forecast. No advance rent, no termly lump sums, and a joint tenancy that can unravel on one notice. Plenty of landlords have responded by letting room by room instead – more admin, but far more resilience.
The market itself has softened in places. PBSA occupancy for 2025-26 came in at 85.4%, down 5.4% on the year, against a pre-Covid norm of 95-98%, according to StuRents data cited by HEPI in April 2026. The share of first-year students living at home has climbed from 32.9% in 2016 to 35.2% in 2025. Those big headline shortfall forecasts – CBRE’s 620,000 beds by 2029 among them – look shakier than they did.
None of that means student property is a bad asset. Far from it. Yields on a well-run student HMO still beat a standard single let comfortably. #
What it means is that location and quality matter more than they did before. A tired six-bed a mile from a campus with falling applications is a different proposition to a good house in a strong university city. All common sense stuff that has applied forever, it just applies more now and student let mortgage lenders know it too.
I remember helping my neice move into her second-year house – six of them, signed up the previous November, and the landlord had probably never once had a void. That landlord’s model doesn’t exist any more. The good ones have adapted. The ones who were coasting on scarcity are the ones putting properties on the market.
It does two things. It generates a risk for some and an opportunity for others. That difference is key to what makes a student let profitable or a problem. Student let mortgage providers are focusing on this more than they were, it isn’t just about the figures, it’s about the proposition.
This is where it gets practical. Underwriting a student let mortgage has always been a bit different from a standard buy-to-let, and the Act has sharpened the differences. Student let mortgage lenders have got a grip of this quickly, landlords need to too.
Lenders stress-test rental income – they check the rent covers the mortgage payment with a margin, at a rate higher than the one you’re actually paying. All pretty standard stuff. On an HMO, some lenders will use the room-by-room rent roll and some will use a more cautious single-household figure. That gap can be the difference between a deal working and not working. Student let mortgage lenders are similar, same property, same income, different calculation of affordability.
Valuation matters too. Larger HMOs are often valued on an investment basis – what the income stream is worth – rather than as bricks and mortar. A softer student market in a particular city feeds straight into that number.
Then there’s structure. Article 4 directions in many university towns mean you need planning permission to convert a family home into an HMO. Licensing conditions always vary by council. Two adjacent authorities, two totally different approaches. Most portfolio landlords now buy through a limited company. And a growing number of lenders want to see how you’ll handle possession under Ground 4A before they’ll treat it as a genuine student let mortgage rather than a standard HMO.
Very few of these questions get a sensible answer from a high street bank. The lenders who do this properly are specialist buy-to-let and commercial lenders, the experienced student let mortgage lenders who have a grip on the market, and most of them don’t deal with the public directly.
We arrange finance across the whole student property picture:
Student let and student HMO mortgages, including larger properties above the six-bed threshold that many mainstream lenders won’t touch but investors see the yields in. Portfolio and limited company lending where you hold several properties. Semi-commercial and commercial mortgages for shops or offices with student flats above. Bridging and refurbishment finance where you’re buying something that needs work, or converting to HMO use, and need to move before a term loan is possible. And development finance for ground-up student schemes and conversions, drawn down in stages as the build progresses.
If you want to sanity-check the monthly cost of a deal before you commit, our repayment calculator is a decent starting point, and there are a few real case studies on the site showing how these deals get put together.
I focus on the financing of properties, in this case the student let mortgage. But I would give some tips to potential borrowers:
If any of that is where you are right now, I’m always happy to have that conversation – no charge, no pressure and I’ll even throw in a free coffee. You can book a call or just drop us a line.

Yes. The sector has changed but it is still viable. Specialist lenders are still actively lending on student let mortgages, HMOs and student lets. What has changed is the underwriting process – lenders want to understand your tenancy structure and how you’ll use Ground 4A, plus how you’ve allowed for longer voids. The deals are there but your paperwork behind them needs to be tidier than it used to be because student let mortgage underwriters will ask for it.
This was my own question I asked someone! It’s a possession ground that lets a landlord of a student house in multiple occupation get the property back in time for the next academic year. The caveats are that all tenants must be full-time students, you have to give them written notice before the tenancy starts that you intend to rely on it and the tenancy can’t be signed more than six months ahead. If that isn’t enough you must give four months’ notice with possession falling between 1 June and 30 September. Now breathe, read it again and get those docs lined up.
No. Only to HMOs – three or more people from more than one household.
Smaller student units sit under the ordinary AST rules with no student-specific possession route, which is worth factoring in before you make the decision to invest.
This is a strange one to me because many international students offer to pay in full in advance, its a mutual thing not the landlord insisting. The answer now is, not before the tenancy agreement is signed, and rent periods must now be monthly.
Less so. PBSA (purpose built student accommodation) can be exempt from the assured tenancy regime and keep fixed terms and advance rent, provided the operator is signed up to a government-specified management code.
That exemption is one reason why many student let mortgage lenders still view well-located PBSA schemes more favourably.
On the whole, it remains pretty positive. Student let mortgages tend to be more easily available via specialist lenders with changes in this sector only going to drive that further. As always, a good landlord, with good paperwork and a strong proposal should find lenders willing to advance on a student let mortgage.
