London Property Exit Strategy: What Non-Resident Investors Need to Know in 2026
Featured Question
What taxes and costs apply when a non-resident investor sells a London property?
Non-resident individuals pay CGT at 18% (basic rate) or 24% (higher rate) on UK residential property gains, with only a £3,000 annual exempt amount. They must also report the sale to HMRC within 60 days of completion — regardless of whether a gain was made — and budget for estate agent fees, conveyancing costs, and any mortgage early-repayment charges on top.
Most Turkish and international investors who buy in London plan their acquisition with meticulous care — then leave the exit strategy as an afterthought. Yet a sale executed at the wrong moment, or structured in the wrong way, can quietly erase a significant portion of what looked like a healthy profit on paper. According to Halifax, the average London property price stood at approximately £538,200 in February 2026 — almost double the UK average of £301,151. An asset of that scale demands that market timing, tax obligations and personal financial goals all sit on the table together before any decision is made. This guide pulls together the essential facts for non-resident investors weighing their options.
Where the London Market Stands Right Now
London residential property has delivered strong long-term capital growth, but it is not immune to short-term volatility. Prices have risen approximately eightfold in nominal terms since 1995, climbing from around £68,000 to roughly £530,000 over that period. That headline figure, however, masks sharp variation across the capital. According to Halifax data, London recorded an annual price decline of 1.0% in February 2026 as southern markets continued to underperform — a reminder that even the capital can move against you in the short run.
The borough-level divergence is equally striking. Average prices in Kensington and Chelsea sit at a very different level to those in Barking and Dagenham, with a vast gap between the two extremes. Where your property sits within that spectrum matters enormously for both pricing strategy and buyer pool.
Holding period makes a material difference. Short-term exits — anything under five years — often look far less compelling once you net off acquisition and disposal costs: stamp duty paid on the way in, estate agent fees, legal fees, and CGT on the way out. Being forced to sell during a down cycle compounds the damage. As a general principle, if the current market offers a strong sale window and the post-tax numbers work, there is rarely a compelling case for waiting on instinct alone.
What Does It Actually Cost to Sell in London?
The direct transaction costs of a London sale fall into three main buckets, and underestimating them is a common mistake.
- Estate agent fees: The average London estate agent commission in 2026 is approximately 1.5% plus VAT (around 1.8% inclusive) — above the national average. On a £500,000 sale under a sole-agency agreement, that translates to roughly £9,000. Multi-agency arrangements can push the rate to between 2.5% and 3.5% plus VAT, and they rarely deliver proportionate benefit.
- Conveyancing fees: Legal costs for a sale typically run in the region of £1,000–£1,500 plus VAT and disbursements, varying with tenure and complexity — leasehold transactions and high-value properties generally attracting fees toward the upper end of that range.
- Energy Performance Certificate (EPC): A valid EPC is legally required for any sale, and typically costs between £80 and £150.
- Mortgage early repayment charge: If there is an active mortgage on the property, breaking it ahead of a fixed-rate period could trigger an early repayment charge. The amount varies considerably by product — review your mortgage terms carefully before you commit to a sale timeline.
- Capital Gains Tax (CGT): Covered in detail below — for non-resident investors this is almost always the single largest cost line.
Illustrative cost summary — £500,000 sale, freehold, sole agency:
- Estate agent commission (1.5% + VAT): approx. £9,000
- Conveyancing fees (VAT inclusive): approx. £1,200
- EPC: approx. £120
- Total direct disposal costs (before CGT): approx. £10,320
These figures provide a useful planning baseline; actual quotes from agents and solicitors will vary.
Capital Gains Tax for Non-Residents: Current Rates and Rules
Non-resident investors selling UK residential property are subject to CGT — there is no bilateral treaty that removes this obligation, and there are no exceptions based on country of residence.
The rules were introduced in stages: residential property sales became subject to CGT for non-residents from April 2015, with the scope expanded to include commercial property and all other UK land from April 2019. The rates in force from 30 October 2024 — and applicable through the 2026/27 tax year — are as follows:
- Basic rate (residential property): 18%
- Higher rate (residential property): 24%
- Annual Exempt Amount: £3,000 per individual (fixed from 2024/25 onwards). To put that in context: the exemption stood at £12,300 in 2022/23 and was cut to £6,000 in 2023/24 before dropping to its current level — a reduction of more than 75% in two years.
- Properties held in a non-resident company: These are subject to Corporation Tax rather than CGT — currently 25% in most cases. Importantly, the 60-day reporting rule that applies to individuals does not apply to non-resident companies in the same way.
Costs you can deduct from your chargeable gain:
- Legal fees, Stamp Duty Land Tax paid on acquisition, and capital improvement costs (not maintenance) are all allowable deductions.
- Rebasing to April 2015: If you purchased the property before 5 April 2015, you can elect to calculate your gain using only the increase in value from that date rather than the original purchase price. This can substantially reduce the taxable gain for long-held assets — a relief that is not available to UK-resident sellers.
Illustrative worked example (not tax advice — for illustrative purposes only):
- Sale price: £500,000
- Market value on 5 April 2015 (rebasing figure): £380,000
- Allowable costs (legal fees, SDLT, etc.): £15,000
- Chargeable gain after rebasing: £500,000 − £380,000 − £15,000 = £105,000
- Annual Exempt Amount: £3,000
- Net taxable gain: £102,000
- CGT at 24% (higher rate assumed): approx. £24,480
- Direct disposal costs (agent + legal + EPC): approx. £10,320
- Estimated total outgoings: approx. £34,800
This scenario is constructed solely to illustrate how the various components interact. For your actual chargeable gain and applicable rate band, qualified professional advice is essential.
The 60-Day HMRC Reporting Deadline: Do Not Miss This
The single most operationally critical rule for non-resident sellers is the 60-day reporting requirement.
The clock starts from the completion date — the date legal title transfers — not from exchange of contracts. Both the report and any tax payment due must reach HMRC within those 60 days.
For non-residents, the rule is stricter than for UK residents: every UK property disposal must be reported within 60 days regardless of whether a gain was made. If you break even, or crystallise a loss, the filing obligation still applies. Miss it by a single day and an automatic £100 fixed penalty kicks in. After six months, an additional penalty of £300 or 5% of the unpaid tax — whichever is greater — is applied.
To file, you need to open a "Capital Gains Tax on UK Property Account" through HMRC's website. This is a separate account from Self-Assessment, though it uses the same Government Gateway credentials.
Optivest Note
Two mistakes come up repeatedly in the cases we see. First: overseas sellers often treat the completion date like a Turkish title-deed handover and assume their solicitor will handle everything automatically. In practice, your UK solicitor will be waiting for your explicit authorisation and instructions before filing with HMRC — this process does not run on autopilot. Second: the rebasing election for pre-2015 purchases can meaningfully reduce the tax bill, yet a significant number of sellers proceed to a standard gain calculation without ever asking whether it applies to them. Put the completion date in your calendar, remind your solicitor about the 60-day obligation in writing, and ask specifically whether a rebasing calculation should be run if you acquired before April 2015.
Sell or Hold? A Decision Framework
There is no universal right answer here, but the following considerations help structure the thinking.
Factors that point towards selling:
- The current market value offers a high price-to-rent multiple, meaning capital is working harder as equity than it would as an income stream from tenants.
- A fixed-rate mortgage is approaching expiry and refinancing on current market terms would materially worsen the property's cash flow.
- You have a specific plan to redeploy capital into a different asset, city or asset class with better risk-adjusted return prospects.
- The property requires significant near-term capital expenditure — an EPC upgrade, structural works or system replacement — that would erode returns without necessarily adding equivalent value.
- Personal liquidity needs have changed, or your investment horizon has shortened.
Factors that point towards holding:
- Rental yield is healthy and local demand remains robust. London's structural undersupply, combined with real wage growth, continues to support tenant demand across most zones.
- The market is at or near a cyclical trough, and near-term capital recovery is a realistic prospect.
- The CGT payable on a sale would consume a disproportionate share of your net proceeds — particularly if the after-tax sale price cannot generate an equivalent return when redeployed.
- You or your family have a long-term personal use case for the property.
Remortgage: Taking Cash Out Without Selling
Selling is not the only way to access the value sitting in a London property. Remortgaging — releasing equity from an asset that has appreciated — can put capital to work without triggering a CGT event.
The average solicitor cost for a remortgage transaction in 2025 stands at £741.67 (VAT inclusive), to which product arrangement fees and a valuation charge may be added depending on the lender's requirements.
The key advantage is straightforward: because the funds released are a borrowing rather than a disposal, the remortgage itself does not create a taxable event in isolation. Whether the increased mortgage interest affects your overall income tax position as a non-resident landlord is a separate calculation — one that has become more complex since the phased removal of full mortgage interest relief for individual landlords. The feasibility of any remortgage depends on the available equity, current tenancy arrangements, and the terms of the product being considered.
Working through the numbers with an FCA-authorised mortgage broker — comparing net cash released versus ongoing servicing cost versus potential CGT saved — is the most reliable way to assess whether remortgaging makes sense in your specific situation.
Frequently Asked Questions
What CGT rate applies when I sell my London property as a non-resident?
From 30 October 2024, non-resident individuals pay CGT on UK residential property at 18% (basic rate band) or 24% (higher rate band). Which rate applies depends on the total of your UK income and gains in the relevant tax year. The Annual Exempt Amount is currently £3,000 per person — down from £12,300 in 2022/23. The applicable rate and your actual chargeable gain should always be confirmed with a qualified UK tax adviser.
Why do I have to file a 60-day report even if I made no gain?
For non-resident sellers, the 60-day reporting obligation applies to every UK property disposal — whether the outcome is a gain, a break-even or a loss, and whether the property is residential or commercial. Failing to file, even with no tax due, results in an automatic £100 penalty. The rule is considerably stricter than the equivalent obligation for UK-resident sellers.
What is rebasing and how does it work for a property bought before 2015?
If a property was acquired before 5 April 2015, non-resident sellers can elect to calculate their gain using the property's market value on that date as the base cost, rather than the original purchase price. This effectively excludes any appreciation that occurred before April 2015 from the taxable computation — which can produce a substantial reduction in CGT for long-held assets. Correct application requires professional tax advice; an incorrect election or calculation can create its own complications with HMRC.
What happens if I remortgage instead of selling?
Remortgaging allows you to release equity from an appreciated property without triggering CGT, since the funds are a loan rather than disposal proceeds. The average solicitor fee for a remortgage in 2025 is £741.67. However, the impact of higher mortgage interest on your income tax position as a non-resident landlord needs separate consideration. An FCA-authorised mortgage broker can model the scenarios and help identify a suitable product.
Can I time the market when deciding to sell?
No one can call the market perfectly, but a handful of practical indicators are worth monitoring: the direction of mortgage rates, price trend data at the borough level, your tenancy situation and approaching capital expenditure commitments such as EPC compliance or major repairs. As a data point: London annual price growth turned negative in February 2026 at -1.0%, suggesting short-term headwinds — though whether that represents a temporary dip or a more sustained correction remains to be seen.
