Selling a House With a Sitting Tenant: 2026 UK Seller's Guide

By Lisa Hayes · 27 July 2026

Yes, you can sell a house with a sitting tenant, and you can do it without waiting for them to leave. You have two routes: sell the property as an investment with the tenant staying put, or get vacant possession first and sell on the open market. Which one is right depends almost entirely on the type of tenancy your tenant has, and that single detail can swing the price you get by tens of thousands of pounds.

I've spent years helping people untangle exactly this situation, and the same confusion comes up every time. People use "sitting tenant" to mean two completely different things, and the gap between them is enormous. So let's clear that up first, then work through your options, the numbers, and what the 2026 rules actually mean for you.

What is a sitting tenant, exactly?

A sitting tenant is anyone living in your property under a valid tenancy at the point you sell. The buyer purchases the house "subject to" that tenancy and steps into your shoes as landlord. Nobody has to move. The rent keeps flowing. The paperwork just changes hands.

Here's where it gets muddy. The phrase gets thrown around for two very different types of tenant, and estate agents, buyers and sellers routinely mix them up:

The ordinary tenant "in situ". This is your standard renter — someone who signed an assured shorthold tenancy (AST) any time from 1989 onwards. From 1 May 2026 their tenancy became an assured periodic tenancy under the Renters' Rights Act, but the principle is the same: they have a contract, they pay a market rent, and there are lawful ways to end the arrangement. Most "sitting tenant" sales are actually this.

The true regulated (protected) tenant. This is the one people fear, and rarely have. A regulated tenancy is a pre-15-January-1989 letting under the Rent Act 1977. These tenants have lifetime security of tenure and pay a "fair rent" set by the Valuation Office Agency's rent officer — usually a fraction of the market rate. In many cases the right passes to a spouse or family member when they die. You generally cannot get them out. If that's what you've got, the rules — and the price — are completely different.

If you're not certain which you have, dig out the original tenancy agreement and check the start date. Anything granted before 15 January 1989 that's never been replaced with a new AST is likely regulated. Everything else almost certainly isn't. This is the most important five minutes of homework you'll do, so don't skip it.

Can you legally sell a house with tenants still in it?

Absolutely. There's no law that says a property must be empty to be sold, and you don't need your tenant's permission to sell the freehold or leasehold. What you're selling is the building plus the tenancy attached to it. Ownership changes; the tenant's rights don't.

You do owe your tenant some basic courtesy and, in places, legal obligation. You must give reasonable notice for viewings (typically 24 hours in writing, and your tenant can decline access — they're not obliged to let strangers in). You can't harass them or cut off services to force them out. And on completion, you must transfer their deposit to the new landlord, along with the prescribed information, or the buyer inherits a liability they won't thank you for.

How much does a sitting tenant devalue a property?

This is the question everyone really wants answered, so let's be concrete. A tenanted house sells for less than the same house empty because owner-occupiers — the people who pay the top prices — are shut out. Nobody's buying a family home they can't move into. That leaves landlords and investors, who buy on yield, not on how the kitchen makes them feel. Fewer buyers, lower ceiling.

The size of the discount depends on the tenancy type, the rent versus market rate, the area, and the state of the paperwork. Broadly, this is what the market looks like in 2026:

To put numbers on it: industry buyers report tenanted properties in 2025 selling for around 20% below comparable vacant homes on average, with regulated cases the extreme end. A £300,000 house with a genuine regulated tenant might change hands at auction for closer to £150,000. That's not a scare story — it's a reflection of what a buyer is actually getting: a modest, capped income and a tenant they can't remove.

• Assured, market rent ~90% of value
• Assured, below-market rent ~75%
• Regulated tenant ~55%

One nuance worth knowing: for a landlord selling a whole portfolio or a block, a tenant in place can actually help. It's income from day one, no void period, no re-letting cost. The discount narrows sharply when the buyer is a professional investor and the numbers stack up. Context matters. Want a realistic starting figure for your own place? A proper house valuation gives you the vacant number; the tenanted figure sits below it by the ranges above.

What changed in 2026, and why it matters to sellers

The Renters' Rights Act 2025 reshaped the rented sector, and it took effect on 1 May 2026. If your last mental model of "how to get a tenant out" is a Section 21 notice, wipe it. That tool is gone.

According to the Government's official information sheet, here's what's now true:

• Assured shorthold tenancies are abolished. Every AST automatically became an assured periodic (rolling) tenancy on 1 May 2026. Fixed terms and set end dates no longer exist for these tenancies.
• Section 21 "no-fault" eviction is dead. No landlord can serve a valid Section 21 notice on or after 1 May 2026. Any served earlier stops being valid after 31 July 2026.
• To end a tenancy, you now need a Section 8 ground. There's a specific ground for landlords who intend to sell (Ground 1A), but two big catches apply: you cannot use it in the first 12 months of the tenancy, and you must give the tenant four months' notice.
• Tenants can leave whenever they like by giving two months' written notice. That cuts both ways — sometimes the simplest route to vacant possession is a tenant who's already thinking of moving.

Your two real options: sell tenanted or sell with vacant possession

Every sitting-tenant sale comes down to this fork. Choose deliberately, because the decision drives your price, your buyer pool and your timeline.

My honest view? For most people who want out quickly — an accidental landlord, someone who's inherited a rented property, a landlord exiting a tightening market — selling tenanted to an investor is the sensible play. You trade a slice of headline value for certainty and speed, and you skip the emotional and legal grind of removing someone from their home. If your tenant is on a low rent or a regulated tenancy, selling tenanted isn't just sensible, it's realistically your only route.

How do you actually get vacant possession now?

If you've decided the top price is worth the wait, here's the honest sequence for an assured (former AST) tenant. Regulated tenants are covered separately below, because most of this simply won't apply to them.

1. Check the tenancy is at least 12 months old. You can't use the sale ground before then. If the tenancy converted from an AST on 1 May 2026, count from its original start date.
2. Serve a valid Section 8 notice citing Ground 1A (intention to sell), giving the required four months' notice. Get the notice right — errors here are the number-one reason possession claims fail.
3. If the tenant leaves by the deadline, you have your empty house and can market it normally.
4. If they don't, apply to court for a possession order. You'll need to evidence your genuine intention to sell. Court backlogs mean this can add months.
5. Only once vacant do you list on the open market for the full owner-occupier price.

Be realistic about the calendar. Four months' notice, plus a possible court claim, plus marketing and conveyancing, and you're easily looking at nine months to a year before the money lands. During that time you carry the mortgage, and possibly a void with no rent. For some the extra value justifies it. For many, it doesn't. Run the sums before you commit.

Who buys houses with sitting tenants?

A tenanted house doesn't sell to the couple looking for a forever home. It sells to people who buy property as a business. Knowing who they are tells you where to take it.

• Buy-to-let landlords and portfolio investors. They want the income and the fact that there's no void. A good tenant with a clean payment history is a selling point, not a problem. This is the natural home for a well-let property — see our guide to selling to a property investor.
• Cash house buyers and "we buy any house" firms. These companies buy tenanted stock routinely and complete fast, because they're not waiting on a mortgage. Read our plain-English take on cash house buyers and how "we buy any house" services actually work before you engage one.
• Property auctions. Tenanted lots — especially regulated ones — are auction bread and butter. You'll likely take a discount, but you get a firm exchange on the fall of the hammer. Handy when certainty beats squeezing the last pound.
• Specialist regulated-tenancy buyers. A niche group buys purely on the reversionary value — they're betting on eventually getting the property back. They know exactly what they're doing, so get independent valuation advice before accepting.

Whichever route, don't hand it to a high-street agent who's never sold a tenanted property. They'll market it as a home, fail, and blame the tenant. You want someone who speaks investor.

Selling to a cash buyer with the tenant in place

If your priority is a clean, quick exit — you want the property gone, the rent worry over, and a date in the diary — a cash sale with the tenant staying put is usually the smoothest path. There's no chain, no mortgage survey to fail, and no eviction to orchestrate. A genuine cash buyer can exchange in days and complete inside two to four weeks.

The trade-off is price. Cash and "we buy any house" buyers pay below vacant market value, and on a tenanted property you're stacking two discounts — the tenanted discount and the quick-sale discount. It's worth understanding roughly what percentage of market value cash buyers pay so the offer doesn't surprise you. For the right seller — someone prioritising speed and certainty over the last few thousand pounds — it's a fair deal. For someone with time and a valuable, empty-able property, it usually isn't. Be honest with yourself about which you are.

• 7–28 daystypical cash completion
• 4 monthsminimum notice to sell via Ground 1A
• 15–40%usual tenanted discount
• Up to 50%regulated-tenant discount

Selling a house with a regulated (Rent Act) tenant

If you've established you genuinely have a regulated tenant, treat this as a different exercise altogether. You are not, in practice, going to get an empty house. These tenants have security of tenure for life, and grounds for possession under the Rent Act are narrow and hard to satisfy. Trying to force it is expensive, slow and usually futile.

What you're selling instead is an investment defined by two things: the capped "fair rent", reviewable every two years and legally limited by the Maximum Fair Rent Order, and the "reversion" — the value the property will unlock when it eventually comes back into the owner's hands. Specialist investors price both. Expect offers 30% to 50% below vacant value, and understand that this is a rational reflection of a low, controlled income and an uncertain wait for possession.

Two pieces of advice. First, get the fair rent registration and the tenancy history in order before you market — buyers pay less for uncertainty, and a regulated tenancy with sketchy paperwork looks like a trap. Second, get an independent valuation from someone who understands reversionary value, not a standard estate agent. The gap between an informed offer and a chancer's lowball can be six figures. If the property feels impossible to shift on the open market, our guide to selling an "unsellable" house walks through the realistic routes.

I inherited a house with a sitting tenant — what now?

This is one of the most common ways people end up here. A relative dies, and the estate includes a property with someone living in it, often for decades. First, work out the tenancy type from the paperwork, because everything flows from that. A long-standing tenant who's been there since the 1980s may well be regulated — which changes both your options and the value of the estate.

You can usually agree a deal before or after probate completes, but you can't complete the legal transfer until you have the grant. Meanwhile the property costs money — insurance, council tax, maintenance — even with rent coming in. If the tenant is regulated and paying a fair rent, that income may barely cover the outgoings. Selling tenanted to an investor is frequently the cleanest way to settle an estate fairly among beneficiaries without a multi-year wait. Our guide to selling an inherited property covers the probate and tax side in detail.

What paperwork will a buyer want to see?

A tenanted sale lives or dies on documentation. Serious investors will price down — or walk — if the file is a mess, because gaps expose them to legal risk and unenforceable possession. Get this together before you go to market:

• The signed tenancy agreement (and the original, if it's a regulated tenancy).
• A rent schedule and payment history — proof the tenant pays and what they pay.
• Deposit protection details and the prescribed information served to the tenant.
• A valid EPC, gas safety record (CP12), and electrical installation condition report (EICR).
• Any registered fair rent certificate for regulated tenancies.
• Correspondence history — a well-behaved tenancy is worth more than a disputed one.

Common mistakes that cost sellers money

A few patterns come up again and again, and every one of them is avoidable:

• Assuming you have a regulated tenant when you don't (or the reverse). Get the tenancy type nailed down. It's the difference between a 10% discount and a 50% one.
• Marketing a tenanted house to owner-occupiers. You'll waste months and take the discount anyway. Go straight to investors.
• Serving a defective Section 8 notice. A single error resets the clock by months. If you're going the possession route, get it checked.
• Under-valuing out of panic. Yes, tenanted means a discount — but "tenanted" is not a synonym for "give it away". Know your reversionary value.
• Leaving the deposit unresolved. Transfer it properly on completion or you hand your buyer a legal headache and yourself a potential claim.

How to start selling your tenanted property

1. Confirm the tenancy type. Check the start date and agreement. Assured or regulated? Everything depends on this.
2. Get two figures. The vacant value and the tenanted value. The gap tells you what you're really deciding between.
3. Choose your route. Speed and certainty (sell tenanted, likely to an investor or cash buyer) versus top price (vacant possession, longer timeline, more risk).
4. Gather the paperwork before you go to market, not after.
5. Compare offers from buyers who understand tenanted stock — not a generalist agent who'll treat the tenant as an obstacle.

Selling with a sitting tenant isn't the nightmare it's made out to be. For most sellers it's simply a different market with a different, well-established set of buyers. Know your tenancy type, price it honestly, and take it to people who buy this stuff for a living — and it can be one of the quickest, least stressful sales you'll ever make.

The smartest first move is to see real numbers side by side. Compare offers on your tenanted property with no obligation, and you'll know within a day or two whether a quick investor sale works for you — or whether it's worth the longer road to vacant possession.
