None of this arrived as one big shock. It is three separate pressures that have stacked up quietly until, for a lot of people, the sums stopped working.
The Renters’ Rights Act has changed the maths
Section 21 is gone. Since May 2026 you can no longer end a tenancy on a no-fault basis, and if you take a property back in order to sell it under the new grounds, you cannot simply re-let it if the sale falls through. The NRLA frames the cost of a forced vacant-possession sale as a modelled figure of around £16,128 per property, based on average rents. Whatever the exact number turns out to be for your property, the direction is clear. An empty-property exit now carries a penalty it did not carry two years ago.
The resolution is straightforward once you see it: if you sell with the tenant in place, you never trigger that penalty at all.
Section 24 quietly raised your tax bill
Section 24 has been fully in force since 2020, but plenty of landlords are only now feeling the full weight of it. You can no longer deduct your mortgage interest before tax. You get a basic-rate credit instead, which means a higher-rate taxpayer is taxed on rent they never actually keep. On a heavily geared portfolio, that can be the difference between a modest profit and a paper loss.
You cannot rewrite the tax rules. You can decide whether holding still makes sense, and for a lot of landlords in 2026 the honest answer is no.
EPC C by 2030 is a bill waiting to land
In January 2026 the government confirmed it: privately rented homes in England and Wales will need to reach EPC C by 2030. For a modern flat, that is close to a form-filling exercise. For an older terrace, it can be a five-figure job with no rent increase to show for it. A lot of landlords are looking at that bill, adding it to the two above, and deciding the timing is right to sell instead.
Put the three together and the exit wave makes sense. This is not panic. It is arithmetic.
