TL;DR / Key takeaways
- You have two broad strategies: sell with the tenant in situ to a landlord or investor, or gain vacant possession first and sell to anyone, including owner-occupiers.
- Selling in situ is faster and avoids eviction, but limits you to investor buyers and a discount to an independent RICS valuation; vacant possession usually fetches more but takes time and cost.
- With Section 21 being phased out under the Renters' Rights Act 2025, regaining possession increasingly rests on a valid ground — most relevantly Section 8 arrears grounds — served correctly with evidence.
- A genuinely problematic tenant (arrears, anti-social behaviour, refusing access) widens the discount because the buyer prices in the cost, time and risk of resolving it.
- Assemble the tenancy pack early — agreement, deposit protection, gas/electrical certificates, EPC, rent statements — to keep an investor sale moving.
- This is general information, not financial, legal or tax advice — seek independent professional advice. L&M is currently AML supervision pending and waitlist only.
What is the best way to sell a property with a problem tenant — keep them in place, or get the property empty first? The two realistic strategies are to sell with the tenant in situ to a landlord or investor, who buys subject to the existing tenancy, or to gain vacant possession first and sell on the open market to anyone. Selling in situ is faster and avoids any eviction process, but narrows the buyer pool to investors and usually means a discount to an independent RICS valuation; gaining vacant possession typically achieves a higher figure but costs time and money, and is harder now that Section 21 is being phased out under the Renters' Rights Act 2025. This guide compares the routes, explains the Section 8 arrears grounds, and sets out how arrears and anti-social behaviour affect price — written from an advisory standpoint, not as legal advice.
What counts as a "problem tenant" when selling
A problem-tenant property is a let property where the tenancy itself complicates a sale — most commonly because the tenant is in rent arrears, engaging in anti-social behaviour, refusing access for viewings or surveys, or is a long-standing sitting tenant on protected terms. The difficulty is not the bricks and mortar but the tenancy attached to them, which is why the route you choose, and the price, turn on resolving or transferring that tenancy cleanly.
It is worth separating two very different situations. A reliable, paying tenant is often an asset — an investor buyer values the income and the avoided void period, so the discount can be modest. A genuinely problematic tenant — in arrears, in dispute, or obstructive — is a liability the buyer must price for, which widens the discount. Being honest with yourself about which you have shapes every decision that follows.
The two strategies — in situ versus vacant possession
Almost every problem-tenant sale comes down to one fork: do you sell the property with the tenant still in it, or do you regain possession and sell it empty?
Strategy A — Sell with the tenant in situ
The buyer purchases the property subject to the existing tenancy and steps into your position as landlord. The tenancy continues on its terms, the deposit and documentation transfer across, and rent keeps flowing through the sale. This avoids the cost, delay and uncertainty of possession proceedings entirely, which makes it the natural route where the tenant is paying but you simply want out. The trade-offs are a narrower market — only investors will buy a tenanted property — and a discount that reflects the tenancy and any associated risk. A property auction is a common venue for tenanted lots, as is a private circulation to an investor network.
Strategy B — Gain vacant possession first
Regain possession through the correct legal process, then sell the empty property to any buyer, including owner-occupiers who typically pay more than investors. This usually achieves the highest figure, but it takes time and money, and is harder where the tenant is in arrears or will not leave voluntarily. With Section 21 being phased out (see below), possession now generally rests on establishing a valid ground and following the statutory steps precisely. This route suits sellers who can absorb the time and want the broadest market and best price.
Section 8 versus the Section 21 phase-out under the Renters' Rights Act 2025
If you pursue vacant possession, the legal landscape in 2026 matters a great deal, because the routes a landlord could once rely on have changed.
Section 21 of the Housing Act 1988 was the "no-fault" route that let a landlord regain possession without giving a reason. The Renters' Rights Act 2025 is phasing this out, moving the system toward periodic tenancies where a landlord must rely on a specified possession ground to regain a property. Section 8 is the fault-based route, used where a ground applies — most relevantly the rent arrears grounds — and it requires serving the correct notice and, if needed, applying to the court for a possession order.
In practice, this means a landlord selling a problem-tenant property can no longer assume a simple no-fault path to an empty property. Where there are serious arrears, the relevant Section 8 arrears grounds remain the most likely route, supported by clear rent records and a correctly served notice. Anti-social behaviour grounds also exist but are evidence-heavy. Timescales depend on court capacity and can be lengthy, which is itself a reason many landlords choose to sell in situ instead. The detail and commencement timing of the reforms are set by the legislation and accompanying regulations, so confirm the current position with a housing solicitor before serving any notice.
Routes compared at a glance
Figures and timescales are indicative planning ranges only — actual outcomes depend on the tenancy, the tenant's conduct, court capacity, condition, demand and your own circumstances. They are not offers or quotes.
| Route | Buyer pool | Likely price level | Best when |
|---|---|---|---|
| Sell in situ — direct to investor | Investors / landlords | Modest–wider discount to RICS valuation | Tenant paying, or you want a quick, private exit |
| Sell in situ — auction | Investors / landlords | Variable; reflects tenancy and risk | Tenanted lot that is hard to price openly |
| Vacant possession — open market | Everyone, incl. owner-occupiers | Full market value once empty | You can absorb time and cost for the best price |
| Vacant possession — fast cash sale | Cash investors | Larger discount to RICS valuation | You need speed and certainty once empty |
How arrears and conduct affect the price
The discount on a problem-tenant property is, at heart, a risk price — the buyer's estimate of what it will cost in money, time and hassle to resolve the tenancy. The best way to keep that discount honest is to express it transparently against an independent valuation.
A fair figure starts from an independent RICS Red Book valuation of the property's open-market value. A tenanted or problem-tenant sale is then expressed as a discount to that RICS valuation, reflecting the income (a positive for a paying tenant) and the risk (arrears, anti-social behaviour, refused access, or possession uncertainty). A reliable tenant narrows the discount; a genuinely problematic one widens it. Anchoring to an independent valuation lets you see exactly what the tenancy is costing you.
The practical takeaway: do not accept a number plucked from the air. Get the independent valuation first, then judge any offer as a percentage of it, with the tenancy risk priced openly. We explain the mechanics in our guide to selling a house fast in London, which covers how a transparent discount to valuation is worked out.
Legal and admin steps — get the pack ready
Whichever route you choose, a tenanted sale moves faster when the paperwork is in order. A buyer's solicitor — especially an investor's — will want to see that the tenancy is compliant and well documented. Assemble the following early:
- The tenancy agreement and any renewals, plus details of the current rent and term.
- Deposit protection evidence — that the deposit is held in an authorised scheme with the prescribed information served.
- Safety certificates — a current gas safety certificate and an Electrical Installation Condition Report (EICR), plus the Energy Performance Certificate (EPC).
- Rent statements showing the payment history and any arrears — transparency here is better than a buyer discovering arrears later.
- Records of any notices served or disputes, so the buyer understands exactly where any possession process has reached.
Gaps or compliance failures — an unprotected deposit, a missing gas certificate — can reduce the price or stall the transaction, and in some cases affect the validity of a possession notice. A short pre-sale compliance check with a housing solicitor or letting agent is usually money well spent.
What we are not doing
To be clear about L&M's role: we are not buying your property, not making a cash offer, and not promising a completion date today. We do not run a live buyer network you can transact through right now, and nothing here is a quote. We are AML supervision pending and operating a waitlist only. This guide is educational — its job is to help landlords understand the options and the law, not to sell a transaction. If you need to act now, instruct a housing solicitor and an estate agent or auction house experienced in tenanted sales, and use this guide to ask sharper questions.
Where a sourcing network fits — and where it does not
A sourcing network can circulate a tenanted or problem-tenant property privately to verified investors who specifically want this kind of stock, rather than listing it on the open market where the tenancy narrows interest. When L&M's seller service opens, we plan to help landlords weigh selling in situ versus gaining vacant possession, benchmark any offer against an independent RICS valuation, and connect to the right route for the circumstances — whether that is a direct investor sale, an auction or the open market once empty.
Registering puts you in line for that guidance and for access to our investor network when the service launches, with no obligation. It is not a substitute for the legal advice a possession process or a tenanted sale requires.
