Selling a rental property: what landlords need to consider
Selling a rental property involves a layer of complexity that selling your own home does not. There is capital gains tax to calculate, a tenant whose position must be handled correctly under the law, a mortgage to redeem, and a conveyancing process that requires disclosure of tenancy documents, deposit records and licensing history. Done well, the exit from a buy-to-let investment can be straightforward and profitable. Done without preparation, it can result in a delayed completion, an unexpected tax bill, or a legal dispute with the outgoing tenant. This article covers everything a buy-to-let landlord needs to think through before putting a rental property on the market.
Vacant possession or selling with a tenant in situ?
The first decision when selling a rental property is whether to sell with vacant possession - meaning the tenant leaves before or on completion - or to sell the property with a tenant already in occupation. Both routes are legitimate but they attract different buyer pools and typically achieve different prices.
Selling with vacant possession
Most residential buyers, including owner-occupiers, require vacant possession. Selling with an empty property opens the sale to the widest possible market and typically achieves the best price. The trade-off is the void period - the time between the tenant leaving and completion during which you receive no rent but continue to pay the mortgage.
To sell with vacant possession, you need the tenant to leave. Under the Renters' Rights Act 2025, which comes into force in May 2026, Section 21 no-fault eviction notices are abolished. The only route to recovering the property for sale is Ground 1A - the new mandatory possession ground that applies where a landlord intends to sell with vacant possession.
Key restrictions on Ground 1A:
It cannot be used in the first 12 months of the tenancy
You must give the tenant two months' written notice
If the tenant does not vacate, you must obtain a court order - the ground is mandatory, meaning the judge must grant possession if the ground is established, but you still have to go through the process
After recovering the property, you cannot re-let it for at least three months - this is a safeguard against landlords using the ground as a pretext to cycle tenants
For a full breakdown of all the possession grounds available to landlords in 2026, see our guide to grounds for possession under the Renters' Rights Act.
Selling with a tenant in situ
Selling a tenanted property - sometimes called selling with a tenant in situ - means the tenant remains in occupation throughout the sale and completion. The buyer takes over as the new landlord, and the existing tenancy continues unchanged. This approach avoids the Ground 1A process and the associated void period, but typically achieves a lower sale price because the buyer pool is limited to investors.
Selling to another landlord or investor can be quicker and simpler in some cases, particularly where the property has a good rental yield and a reliable tenant. Some investors actively seek tenanted properties because it means immediate rental income from day one.
The discount for a tenanted sale varies but is typically 10-20% below vacant possession value, reflecting the limited buyer pool and the risk premium investors attach to taking on an existing tenancy. For some landlords, particularly those selling in a hurry or those with long-standing tenants they do not want to displace, this trade-off is worthwhile.
Capital gains tax when selling a rental property
Capital gains tax (CGT) is the most significant financial consideration for most buy-to-let landlords selling a property. Unlike selling your main residence, selling a rental property does not qualify for full Private Residence Relief (PRR), meaning the gain is taxable.
CGT rates on residential property
Since October 2024, CGT rates on residential property disposals are:
18% for gains falling within the basic rate income tax band
24% for gains falling within the higher or additional rate band
The rate that applies depends on your total taxable income in the year of disposal, combined with the chargeable gain. If your income plus the gain takes you into the higher rate band, the portion of the gain above the basic rate threshold is taxed at 24%.
The annual CGT allowance
Every individual has an annual CGT allowance, the amount of gain you can make before CGT is due. The allowance was reduced significantly in recent years. For the 2025/26 tax year, it is £3,000. This means only gains above £3,000 in the tax year are subject to CGT.
If the property is jointly owned, both owners have their own allowance. A jointly owned property sold by two basic rate taxpayers with a combined gain of £6,000 or less would therefore produce no CGT liability.
Calculating the chargeable gain
The chargeable gain is broadly calculated as:
Sale proceeds (or market value if sold below market value)
Minus the original acquisition cost
Minus allowable costs - stamp duty on purchase, legal fees on purchase and sale, estate agent fees on sale, and the cost of capital improvements made during ownership (not repairs or maintenance)
Minus the annual CGT allowance
Equals the chargeable gain
Capital improvements, such as a new kitchen, an extension, or a loft conversion, can be deducted from the gain. Routine repairs and maintenance cannot. This is a different rule from the income tax treatment of expenses: repairs are deductible for income tax purposes but not for CGT purposes, whereas capital improvements are deductible for CGT but not for income tax.
For a full explanation of the difference between capital and revenue expenditure and which costs are deductible for income tax, see our guide to allowable expenses for landlords.
Private Residence Relief
If the property was at any point your main home - for example, if you lived in it before converting it to a rental - you may be entitled to partial Private Residence Relief (PRR). PRR exempts the portion of the gain that relates to the period during which the property was your principal private residence. The final nine months of ownership always qualify for PRR regardless of occupation, as long as the property was at some point your main home.
The calculation of partial PRR can be complex. If the property was your main home for some years and a rental for others, you will need to apportion the total gain across the ownership period. Taking specialist tax advice is worthwhile if PRR may apply to your situation.
The 60-day CGT reporting deadline
Since April 2020, a landlord selling a UK residential property must report the gain to HMRC and pay any CGT due within 60 days of the date of completion. This is a separate requirement from the annual self-assessment tax return. Missing the 60-day deadline results in an automatic penalty and interest charges.
The reporting is done through HMRC's online CGT service. You will need to calculate the gain, estimate your income tax band for the year, and pay the CGT before filing. Any over- or under-payment is reconciled through self-assessment at the end of the tax year.
Landlords affected by Section 24 mortgage interest relief restrictions should also factor in how the sale affects their overall tax position for the year. See our complete guide to Section 24 mortgage interest relief for how this interacts with income from rental properties.
Timing your sale: tax year and market considerations
The timing of a sale can have a material impact on the CGT bill. A few considerations worth discussing with a tax adviser before putting the property on the market:
Tax year timing - if you complete the sale early in the tax year (April to August), you have longer to plan the rest of your income for the year and ensure the gain falls in the most favourable band. Completing close to the end of the tax year (February or March) leaves little flexibility
Using both partners' allowances - if the property is in a single name, it may be worth considering whether transferring a share to a spouse or civil partner before sale would allow both CGT allowances to be used. Transfers between spouses are treated at no gain/no loss for CGT purposes
Spreading the gain - for portfolio landlords selling multiple properties, spreading sales across different tax years uses the annual allowance each year and may keep gains in lower rate bands
Market timing - selling in spring or early summer typically achieves the best prices and shortest time on market in most UK residential markets; autumn is also strong; the Christmas period and deep winter are generally weaker times to sell
Tenancy end date - if seeking vacant possession, aligning the Ground 1A notice period so that the tenant leaves at a point that allows spring or early summer marketing makes sense; factor in two months' notice plus potential court proceedings if the tenant does not vacate voluntarily
Getting the property ready for sale
Energy Performance Certificate
An Energy Performance Certificate (EPC) is legally required before a property can be marketed for sale. If the existing EPC has expired (they last ten years) or was issued before any energy-efficiency improvements you have made, commission a new one before listing. A higher EPC rating can support the asking price and reassure buyers of lower running costs.
For landlords who have invested in energy efficiency improvements, see our MEES and energy efficiency guide for what work qualifies and how to evidence it.
Presentation
If selling with vacant possession, the property should be thoroughly cleaned, any outstanding repairs completed, and walls repainted in neutral colours before photography and viewings. Minor cosmetic investment at this stage almost always pays back in sale price and time on market.
If selling with a tenant in situ, you will need the tenant's cooperation for viewings and photography. Give reasonable notice for all access and respect the tenant's right to quiet enjoyment - typically a minimum of 24 hours' written notice is required, and more notice is usually better for maintaining the relationship. Consider whether a small goodwill gesture to the tenant (a contribution to their utility bill or similar) is worth offering in exchange for their cooperation.
Choosing an estate agent
For a tenanted property, use an estate agent who has experience selling investment properties. They will understand how to present the rental yield to investor buyers, how to handle viewings with an occupying tenant, and how to manage the additional documentation required in the conveyancing process. Some agents specialise in portfolio and investment property sales and can access a direct network of investor buyers.
Conveyancing obligations when selling a rental property
The conveyancing process for a rental property involves additional documentation and disclosures compared to selling a vacant owner-occupied home. Your solicitor will need to prepare or obtain the following.
TA6 property information form
The TA6 form requires disclosure of any disputes, planning issues, building works and other matters affecting the property. For a rental property, you should also disclose any licensing requirements that apply or have applied (mandatory HMO licence, selective licence), the current licensing status, and any notices or enforcement action from the local authority.
Tenancy documentation
If selling with a tenant in situ, your solicitor will need to provide the buyer's solicitor with:
The current tenancy agreement
The deposit protection certificate and prescribed information
The current gas safety certificate, EICR, EPC and How to Rent guide (evidence of service to the tenant)
The HMO licence if applicable
Any outstanding maintenance issues or repair notices
Rent payment history if requested
The buyer is taking on the tenancy and all its associated obligations on completion. They need full visibility of the tenancy terms and compliance history.
Deposit transfer
If the deposit is held in a custodial scheme, you will need to transfer the scheme registration to the new landlord on completion, or agree a process for the existing scheme to release the deposit to the buyer who re-protects it. If the deposit is held under an insured scheme and the money is in your bank account, it must be transferred to the buyer on completion.
The prescribed information will also need to be re-served by the new landlord after the transfer of ownership, as the scheme details will have changed. Make sure the buyer's solicitor is aware of this obligation and that the completion process accounts for it.
Redeeming a buy-to-let mortgage
If the property has an outstanding buy-to-let mortgage, you will need to redeem it on completion. The key steps are:
Obtain a redemption statement. Contact your lender for a redemption figure - the amount needed to clear the mortgage in full on or around the anticipated completion date. The figure changes daily as interest accrues, so ask for a statement valid for a specific date and request an updated one if the completion date changes.
Check for early repayment charges (ERCs). Most fixed-rate buy-to-let mortgages carry ERCs during the fixed rate period. These can be substantial - typically 1-5% of the outstanding balance. Check your mortgage terms before committing to a sale timeline and factor any ERC into your net proceeds calculation.
Notify the lender. Once you have a confirmed completion date, notify the lender so they can prepare for the redemption. Your solicitor will handle the actual redemption on completion day.
Confirm the title is clear. The mortgage lender holds a charge over the property. This charge is removed on redemption. Your solicitor will confirm that the title is clear of the charge before registering the transfer with HM Land Registry.
What happens to the tenant when the property is sold?
If the property is sold with a tenant in situ, the tenancy does not end on completion. The buyer becomes the new landlord automatically by operation of law on the date of completion. The tenant's rights are unchanged - the same rent, the same notice periods, the same terms - but the landlord's obligations transfer to the new owner.
As the selling landlord, you should:
Notify the tenant in writing of the sale and the new landlord's name and contact details as soon as reasonably practicable after completion
Transfer any security deposit to the new landlord and ensure the scheme is updated accordingly
Pass all tenancy documents - agreement, deposit certificate, prescribed information, compliance records - to the new landlord
Ensure any outstanding repairs or maintenance requests are either resolved before completion or clearly disclosed to the buyer
If the property is sold with vacant possession, the tenant will have already vacated following the Ground 1A process. In this case, handle the deposit return and checkout process in the normal way before completion.
Stamp Duty Land Tax: implications for the buyer
As the seller you do not pay Stamp Duty Land Tax (SDLT), that is the buyer's obligation. However, understanding the SDLT position can help you price the property and negotiate effectively.
See our Stamp Duty Calculator
A buyer who already owns residential property and is purchasing a rental property or second home will pay the higher rate SDLT surcharge. The surcharge is currently 5 percentage points above the standard residential rates on the full purchase price (from October 2024). This means an investor buying a property for £300,000 pays significantly more SDLT than a first-time buyer buying the same property.
This additional cost is a real factor in investor buyers' purchase calculations. When negotiating price with an investor buyer, be aware that they are factoring SDLT into their total acquisition cost and their required yield. A realistic asking price that accounts for this will attract more serious buyers and reduce the negotiation gap.
Portfolio landlords: considerations when selling part or all of a portfolio
For landlords with multiple properties, selling one or more raises additional considerations beyond those that apply to a single disposal.
Spreading disposals across tax years
Each tax year, the annual CGT allowance resets. Portfolio landlords selling multiple properties should plan disposals to use the allowance efficiently. Selling two properties in the same tax year combines both gains against a single £3,000 allowance; selling one per year uses an allowance each time.
Incorporation and CGT
Some portfolio landlords operate through a limited company. Selling a property from a company does not trigger personal CGT - the company pays Corporation Tax on its gains. However, extracting the profit from the company as a dividend or salary creates a further tax event. The overall tax efficiency depends on the specific structure, your individual tax position, and how the proceeds are used.
Selling the whole portfolio
Selling an entire letting portfolio - multiple properties to one or several buyers - involves the same per-property process but at scale. Some portfolio sales are structured as a block sale to a single investor buyer, which can be more efficient but typically results in a larger overall discount to individual vacant possession values. An agent specialising in portfolio sales can advise on whether a block sale or phased individual sales is likely to achieve the better outcome.
Pre-sale checklist for landlords
Before putting a rental property on the market, work through this checklist.
Decide: vacant possession or sell with tenant in situ
If vacant possession: serve Ground 1A notice (minimum 2 months, not in first 12 months of tenancy) and plan for potential court proceedings
Get a CGT calculation from a tax adviser, including any PRR entitlement and the 60-day reporting obligation
Check for early repayment charges on the buy-to-let mortgage and get a redemption statement
Commission a new EPC if the current one is expired or out of date
Instruct a solicitor experienced in landlord and investment property conveyancing
Gather all tenancy documents: agreement, deposit certificate, prescribed information, gas safety certificate, EICR, EPC, How to Rent guide
Check licensing status: is the property subject to mandatory HMO licensing, additional licensing or selective licensing? Ensure the licence is current and disclose to the buyer
Prepare any outstanding repairs or maintenance so the property is presented at its best
Plan the deposit transfer or return process
Frequently asked questions
Can I sell a rental property while the tenant is in a periodic tenancy?
Yes. You can market and sell a property with a tenant on a periodic tenancy either as a tenanted sale (the buyer takes over as landlord) or by serving a Ground 1A notice to achieve vacant possession before completion. If selling with a tenant in situ, the completion date simply needs to be agreed and the tenancy transfers to the buyer on that date.
Do I need to tell the tenant I am selling?
There is no strict legal obligation to tell a tenant you intend to sell, but good practice and the requirements for viewings make early communication sensible. If you are seeking vacant possession via Ground 1A, the notice itself makes your intention clear. For a tenanted sale, notifying the tenant early, explaining the process, and reassuring them that their tenancy continues unchanged reduces anxiety and usually results in better cooperation for viewings.
What if the tenant refuses to allow viewings?
A tenant on a periodic tenancy has a right to quiet enjoyment of the property. They must allow access for viewings with proper written notice (usually 24 hours minimum, and the tenancy agreement may specify more) but they cannot be forced to cooperate with photography or presentation of the property. If a tenant actively obstructs viewings without reasonable justification, seek legal advice. In practice, maintaining good relations and giving generous notice resolves most access difficulties.
What happens to the tenant's deposit when I sell?
The deposit must be transferred to the new landlord on completion. If protected in a custodial scheme, the scheme registration is updated to reflect the change of landlord. If held as an insured scheme, the physical funds are transferred to the buyer and the new landlord re-protects in their preferred scheme within 30 days, serving fresh prescribed information to the tenant. Do not deduct from or return the deposit to the tenant simply because you are selling, the tenancy continues and the deposit must travel with it.
Can I sell a property that has an HMO licence?
Yes. The HMO licence is attached to the property and the licence holder, not just the property. On a sale, the existing licence does not automatically transfer to the new owner. The buyer will need to apply for a new licence in their own name before operating the property as an HMO. Some local authorities allow a temporary licence or a transfer application during the transition period, but the buyer should take advice on the local authority's specific process.
Key takeaways
Decide early whether to sell with vacant possession or with a tenant in situ. This determines the timeline, buyer pool and likely price
Under the Renters' Rights Act 2025, vacant possession for sale requires Ground 1A: two months' notice, not available in the first 12 months of the tenancy, with a three-month re-letting restriction after possession
CGT on residential property is 18% (basic rate) or 24% (higher rate), with a £3,000 annual allowance. Report and pay within 60 days of completion
Allowable CGT deductions include acquisition costs, legal fees, estate agent fees and capital improvements, but not repairs or maintenance
Check for early repayment charges on your buy-to-let mortgage before committing to a sale date
For a tenanted sale, provide the buyer with all tenancy documentation and arrange for the deposit to be transferred on completion
Timing the sale across tax years can significantly affect the CGT position. Take specialist tax advice before selling
