You have two routes when selling a rental: sell with the tenants in place, or end the tenancy first and sell with vacant possession. Since 1 May 2026 the second route runs on the Renters’ Rights Act’s selling ground, which means four months’ notice, no notice at all in the first twelve months of a tenancy, and a twelve month ban on re-letting if the sale falls through. Which route makes sense depends on your buyer, your mortgage and your timescale.
Both routes work. But the new rules have turned the vacant possession route into a one way door, so the decision deserves more care than it needed two years ago. Here is how each one runs.
Route one: selling with the tenants in place
A sale with tenants in situ means the tenancy carries on and the buyer takes over as landlord on completion. The rent keeps coming in until the day you sell, there is no void period, and nobody has to be served notice. The trade off is the buyer pool: you are selling to other landlords and cash investors rather than to people who want to live there, and investors buy on the numbers. A tidy file helps enormously: the tenancy agreement, protected deposit, gas safety record, electrical report and EPC all get checked, and the deposit itself transfers to the buyer through the conveyancing.
Route two: ending the tenancy to sell
Since the Act took effect, ending a tenancy to sell means the specific selling ground rather than a Section 21 notice. The ground cannot be used in the first twelve months of a tenancy, the notice period is four months, and you should expect to evidence a genuine intention to sell, an estate agent instruction or correspondence with a conveyancer being the obvious proof. Once the tenants leave you are carrying the mortgage, council tax and utilities with no rent coming in until completion, which belongs in the sums.
Two routes: sell with the tenants staying, or end the tenancy first using the selling ground introduced on 1 May 2026.
The selling ground needs four months notice and cannot be used in the first twelve months of a tenancy.
If the sale falls through after notice, you cannot re-let for twelve months. The vacant route is now a one way door.
Selling with tenants in place keeps the rent coming until completion, but the buyer pool is landlords and cash investors.
Check your early repayment charge before committing. The four month notice period is long enough to line the sale up with the end of a fix.
The twelve month re-letting ban, and why it matters
Here is the part that changes behaviour: if you serve notice on the selling ground and the sale falls through, you cannot re-let or re-market the property for letting for twelve months from the possession date in the notice. Breaching that carries civil penalties of up to £7,000, rising to £40,000 for repeat breaches, plus exposure to rent repayment orders. So serving notice to sell is no longer something to do speculatively while you make your mind up. Be sure, then serve. I covered the wider changes in what the Renters’ Rights Act means for buy to let mortgages.
What happens to your buy to let mortgage when you sell?
The mortgage is repaid from the sale proceeds on completion. The thing to check before committing to either route is the early repayment charge: if you are inside a fixed period, selling can trigger a charge of thousands of pounds, and the four month notice runway on the selling ground gives you a real opportunity to line the sale up with the end of the fix. If the plan is to sell one rental and buy another, some lenders will let you port the product across, subject to their criteria and timing. The timing questions are the same ones I set out in product transfer versus remortgage.
Which route sells for more?
Vacant possession opens the property to the whole market, including owner occupiers, which is usually the larger and more emotional buyer pool. A tenanted sale trades on yield to a smaller pool of investors, and the price reflects the numbers rather than the feel of the place. How big the gap is depends on the property and the local market, and anyone quoting you a universal discount figure is guessing. What I can say is that a well documented tenancy with a reliable tenant is a genuine selling point to a landlord buyer, not a defect.
Selling to another landlord: what the buyer’s lender will want
If your buyer needs a buy to let mortgage, the rent has to pass their lender’s stress test, and their conveyancer will want the tenancy paperwork: the agreement, deposit protection certificate, gas and electrical records, the EPC and a rent schedule. A sale with tenants in place lives or dies on that file being in order. Get it together before the listing, not during the transaction.

Do you have to tell your tenants you are selling?
If you are selling with the tenancy continuing, there is no notice to serve, but the sale will go better with the tenants onside, because viewings need their cooperation and a hostile tenancy shows. Tell them early, explain that their tenancy carries on unchanged with a new landlord, and agree how viewings will work. If you are using the selling ground, the formal notice does the telling, and the four months gives everyone time to plan.
What about capital gains tax when you sell?
A rental sold at a gain can mean capital gains tax at 18% or 24% after the £3,000 annual exempt amount, and residential disposals have to be reported and paid within 60 days of completion. The detail, and what is deductible, is one for your accountant, and I have covered the broader picture in tax implications for buy to let.
Selling because of the new rules?
Some landlords are selling up because of the Act and the direction of travel, and some investors are buying precisely because others are leaving. I wrote about that dynamic in landlords are selling up. Whether leaving is right for you is a personal and financial question, not a headline question, and it deserves real numbers: what the property nets you today, what it would sell for, and what the alternative use of the money looks like.
So what should you actually do?
Decide the route before you touch anything formal. Check your early repayment charge dates first, get the tenancy file in order, and only serve notice on the selling ground once you are certain, because the twelve month ban removes the option to change your mind. If part of the plan involves a mortgage, whether that is timing the redemption, porting to another purchase or restructuring what you keep, that is where I come in.
