CGT Warnings Before Budget: Funding a Property Purchase
Private Wealth Market Intelligence · 5 October 2026

Budget Uncertainty Meets a Property Deadline

Wealth-platform leaders have warned against further CGT increases. If a client is reviewing an asset sale, establish how the property completion can be funded and what each option would cost.

Wealth Bosses Warn Against CGT Rises Ahead of Budget. What If Your Property Purchase Cannot Wait?

Investment-platform leaders are warning about the consequences of higher capital gains tax. For a buyer reconsidering an asset disposal, the immediate issue may be funding a property completion while the wider decision receives advice.

Chief executives of major UK investment platforms have warned against further capital gains tax increases ahead of the 28 October Budget, according to Financial Times reporting. Their intervention raises a practical question for property buyers: if the planned asset sale is being reconsidered, how will the purchase complete?

The warnings concern possible changes and their effect on investment and disposal behaviour. They do not announce a new CGT increase. HM Treasury has confirmed the Budget date, but clients should not assume that selling before it, or waiting until afterwards, will deliver a particular tax result.

For an asset-rich buyer, the immediate difficulty can be a mismatch between wealth and available cash. A client may have £8m of investments and need £2m for completion, yet prefer to review the disposal with their tax adviser and wealth manager before making it. Suitable borrowing may create time for that decision, provided its costs, risks and repayment plan are acceptable.

What the News Changes for Property Buyers

The Budget provides a defined planning date. HM Treasury has confirmed Wednesday 28 October 2026.

The FT reports industry warnings about possible CGT increases. This is lobbying and speculation, rather than confirmation of a further increase.

The property timetable may continue regardless. A client reviewing an intended disposal still needs to establish how any committed purchase will be funded.

The Property Deadline and Investment Decision May No Longer Align

A purchase might initially be planned around selling investments, disposing of another property or receiving business proceeds. If the cash source is delayed or reconsidered, the amount due on completion does not necessarily change.

The first task is to calculate the actual funding gap. A £2m purchase does not always require £2m of borrowing: available cash, a deposit already paid and other committed funds may reduce the requirement. Purchase taxes, legal costs and retained reserves can move the figure in the opposite direction.

The second task is to establish duration. A decision deferred until after 28 October may still require further advice, dealing, settlement or a property sale. The financing timetable needs to allow for that practical sequence.

Where contracts have been exchanged, the solicitor should explain the obligations and any scope to alter completion. The buyer needs funding that can meet the legal timetable. Wealth on paper does not substitute for cleared funds when the transaction requires them.

Which Borrowing Route Fits the Gap?

The appropriate route depends on the available security, borrower, deadline and intended repayment. A conventional mortgage, private-bank facility, property-backed bridge or securities-backed loan may each be relevant in different circumstances.

Interest-only is a repayment basis that can feature within different facilities. It may reduce scheduled payments compared with capital repayment borrowing, but the principal remains outstanding and needs an acceptable repayment strategy.

Potential routes for assessment, subject to individual suitability and lender approval.
Route Potential Role What Needs Testing
Residential mortgage Purchase funding with a continuing borrowing requirement Affordability, property eligibility, timing and early repayment terms
Private-bank finance Funding supported by a wider asset or banking relationship Security, asset requirements, servicing, covenants and relationship costs
Property-backed bridging A defined gap before a supported repayment event Valuation, legal work, charges, maturity and an achievable exit
Securities-backed or Lombard lending Liquidity against eligible investment collateral Holdings, custody, permitted use, collateral maintenance and repayment

A longer-term mortgage might have attractive pricing but charges that make early repayment expensive. A flexible short-term facility might fit the expected duration more closely but carry substantial arrangement costs. The complete terms determine which option deserves consideration.

An £8m Portfolio Does Not Establish Borrowing Capacity

In the illustrative case of an £8m portfolio supporting a £2m requirement, the requested loan is 25% of the headline investment value. That calculation says little about what a lender will advance without knowing the holdings.

Listed investments, concentrated shares, restricted stock and private assets can receive very different lending values. Some holdings may not be accepted at all. Ownership, currency, custody and existing security also shape the relevant lender market.

The review should establish the eligible borrowing base and the headroom available under less favourable conditions. It should also clarify whether assets can remain with the current custodian or whether transfers and additional documentation are required.

Those operational steps can matter when completion is close. A facility that appears suitable commercially still needs to be approved, documented and available to draw in time. Willow’s securities-backed lending guide explains the distinction between portfolio market value and the collateral value recognised by a lender.

Borrowing Can Bring Forward an Unwanted Asset Sale

Portfolio-backed borrowing introduces a requirement to maintain sufficient collateral. Depending on the agreement, weaker asset values or changes in lending values can lead to demands for more security, repayment or asset sales.

A client borrowing to postpone a disposal needs to understand that possibility. If the facility is stretched and there is no accessible reserve, a market fall could require action at an inconvenient time. The finance review should show how the client would respond.

Property-backed borrowing avoids that particular investment-collateral exposure but introduces its own security and repayment obligations. The comparison should consider the assets placed at risk and how each facility behaves if the intended exit is delayed.

Retaining the Assets Also Retains Their Market Risk

Borrowing creates liquidity while adding financing costs and obligations. The client remains exposed to changes in asset values. Their investment adviser should assess that combined position alongside the proposed lending terms.

What Could Six Weeks of £2m Borrowing Cost?

Short-term interest can look modest relative to a large property purchase. Fees and minimum charging periods may have a much greater effect on the comparison.

For illustration, £2m charged at a hypothetical 6% annual simple interest rate for 42 days produces approximately £13,808 of interest, using a 365-day year. An illustrative 1% arrangement fee adds £20,000, taking those two items to approximately £33,808.

This is a calculation rather than a quotation. It excludes legal, valuation, custody and exit costs, as well as any minimum interest period. A lender requiring three months of interest would not charge solely for six weeks because the borrower repaid earlier.

Hypothetical £2m facility: 6% annual simple interest and a £20,000 arrangement fee. Other costs excluded.
Duration Illustrative Interest Interest Plus Arrangement Fee
Six weeks / 42 days Approximately £13,808 Approximately £33,808
Twelve weeks / 84 days Approximately £27,616 Approximately £47,616

The client’s advisers can use the complete cost when evaluating the intended funding route. The assessment should remain useful if no relevant Budget change occurs. A possible tax outcome cannot be treated as a guaranteed benefit against which certain borrowing costs are offset.

What If the Client Still Does Not Want to Sell Afterwards?

The repayment plan needs an answer before the facility is drawn. Borrowing intended to last six weeks may remain outstanding if the client retains the assets, cannot complete a sale or receives less cash than expected.

A planned exit and an available alternative are different things. Future refinancing requires its own approval, and a lender is not obliged to extend a facility because the borrower’s plans have changed.

Other cash resources, a supported longer-term mortgage or a different disposal may provide alternatives. Their feasibility needs checking rather than simply listing them in an application. Where the only exit depends on a speculative future decision, borrowing may be unsuitable.

The Tax Adviser Determines the Relevant Disposal Timing

The date cash arrives is not necessarily the date relevant to tax. Contract terms, asset type and applicable rules can affect when a disposal is treated as taking place. A tax adviser should establish the position before a client relies on a particular sequence.

They should also assess any Budget announcement, including its effective date and relevance to the individual. Waiting until after 28 October does not guarantee an improved outcome, and selling before it does not automatically secure a particular treatment.

Willow assesses borrowing within its remit. The wealth manager considers the investment decision, the tax adviser assesses tax consequences and the solicitor advises on transaction obligations. With the client’s authority, those professionals can coordinate the relevant timetable.

What a Pre-Budget Liquidity Review Should Establish

The review starts with the commitment requiring cash and the reason the original funding route is under consideration. It then tests the borrowing amount, duration, security and repayment.

Amount and deadline Completion funds, transaction costs, available cash and the date cleared funds must be available.
Available security Property, eligible investments, ownership, existing charges, custody and relevant jurisdictions.
Cost and downside Interest, fees, minimum charging periods, security obligations and the consequences of delay.
Repayment and advice Expected exit, alternative resources, supporting evidence and coordination with professional advisers.

Wealth managers, accountants and private-client advisers can begin with an anonymous outline. The immediate purpose is to establish whether a credible finance route merits fuller assessment, without requiring the introducing adviser to select a lending product first.

How Willow Private Finance Can Help

Willow can compare appropriate property-backed, private-bank and portfolio-backed borrowing where the purchase timetable and expected liquidity event do not align. The assessment considers execution, servicing, collateral and eventual repayment.

A suitable facility may allow a transaction to proceed while the disposal receives further advice. In other cases, the costs or risks may favour using cash, completing the planned sale or reconsidering the purchase timetable.

Knowing what can be borrowed, against which security and on what terms gives the client a firmer basis for that decision. Budget speculation provides a reason to review the position; the finance still needs to work on its own merits.

Frequently Asked Questions

Practical questions about property funding while an asset disposal is under review.

Has a further capital gains tax increase been confirmed?

The FT report discussed here describes industry warnings about a possible increase, rather than an announced change. HM Treasury has confirmed the Budget date as 28 October 2026. Decisions about disposal timing should be made with a tax adviser.

Can I borrow against investments to fund a property purchase?

Potentially, where the holdings are eligible collateral and the lender accepts the purpose, borrower and custody arrangements. Portfolio value alone does not establish borrowing capacity. The repayment terms and response to falling collateral values must be assessed.

Is temporary borrowing automatically cheaper than selling an asset?

No. Interest, fees, minimum charging periods and collateral risks may outweigh the benefit of delaying a sale. The comparison should include realistic borrowing durations and the disposal position assessed by the client’s tax and investment advisers.

What happens if I decide not to sell the asset after the Budget?

The borrowing still needs to be serviced and repaid under its terms. An alternative repayment route should be assessed before committing. Refinancing or extending the facility is not guaranteed.

Does Willow advise when I should sell investments or property?

Willow assesses borrowing options and lending terms within its remit. Investment, tax and legal decisions remain with the client’s appointed advisers. With authority, the professionals can coordinate the funding timetable and relevant consequences.

Important Notice

This article provides general information, not a personal mortgage recommendation or investment, tax or legal advice. It was published on 5 October 2026. Lending availability, rates and terms can change.

The FT report describes industry warnings concerning possible capital gains tax changes. It is not a government announcement of a further increase. The Budget date is confirmed as 28 October 2026. Neither an improved tax outcome nor a particular effective date should be assumed.

The £8m investment portfolio and £2m liquidity requirement are hypothetical. The resulting 25% ratio is arithmetic, not an indication of lending eligibility or a safe collateral level.

The cost illustrations apply 6% annual simple interest to a constant £2m balance for 42 or 84 days using a 365-day year, plus a hypothetical £20,000 arrangement fee. They are not quotations and exclude other fees, minimum interest periods, compounding and differences in facility terms.

Borrowing requires a suitable servicing and repayment plan. Refinancing and extensions are not guaranteed. Securities-backed facilities can require additional collateral or repayment and may permit asset sales if their terms are not maintained.

The relevant tax treatment and disposal date should be established by a qualified tax adviser. Willow assesses borrowing within its remit and can coordinate with the client’s professional advisers where authorised.

Your home or property may be repossessed if you do not keep up repayments on borrowing secured against it. Pledged investments may be sold if the terms of a securities-backed facility are not maintained.
