London's property market is producing an interesting divergence. Prices remain sensitive and buyers continue to negotiate carefully, but the number of transactions moving towards completion is increasing. For HNW buyers, that can change the value of arranging finance early.
Fresh Knight Frank figures indicate that activity across London's mainstream residential market strengthened materially during the summer. Exchanges increased 15% year on year in the three months to July, while July itself recorded a 34% annual increase.
Offers accepted were reportedly 35% higher over the three-month period, while new applicant numbers increased 7%. Knight Frank identified particularly strong activity in markets including Chelsea, Kensington, Notting Hill, Wandsworth and Queen's Park.
The figures should not be interpreted as evidence that the entire London property market has suddenly moved decisively in favour of sellers. Prime London remains highly price-sensitive after a prolonged period of adjustment, and buyers continue to distinguish sharply between correctly priced, high-quality property and stock they believe is overvalued.
The more useful signal is different: transaction activity can recover before prices do.
London exchanges rose 34% year on year in July, while offers accepted increased 35% across the three months to July. Buyers may still have negotiating power, but more of them are now transacting.
Why Transaction Activity Matters More Than the Headline Price Index
Property-market commentary naturally focuses on prices. For someone preparing to buy a £2 million, £3 million or £5 million London home, however, transaction activity can sometimes be the more important short-term indicator.
A quiet market gives buyers time. A purchaser may view a property, spend several weeks considering it, obtain mortgage terms, speak to a private bank and wait for another asset to sell before making a serious commitment.
When more buyers begin transacting, that timeline can compress — even if average prices have not started rising.
The distinction is particularly relevant in prime property because the market is not homogeneous. A broadly weak London index can coexist with competitive bidding for an exceptional house on a sought-after street, a well-positioned family home or an apartment that is realistically priced.
Buyers therefore need to distinguish between market-wide pricing conditions and competition for the specific property they actually want to own.
HNW Buyers Have Had the Luxury of Time
For much of the recent market correction, wealthy buyers could afford to be patient.
Higher borrowing costs, changes to taxation and weaker sentiment reduced transaction volumes. International buyers also had to weigh UK property opportunities against investments elsewhere, while domestic purchasers often delayed moves until the interest-rate environment became clearer.
That environment created an advantage for cash-rich buyers. Where a seller had been waiting months for a credible offer, a purchaser could negotiate aggressively while working through the finance in parallel.
Rising exchanges do not eliminate that advantage overnight. They do, however, suggest that buyers who have been waiting for the perfect moment should consider what happens if the right property appears and there is another credible purchaser behind them.
The Funding Question Changes When Competition Returns
In a slow market, the natural mortgage question is often: “How cheaply can I finance the purchase?”
As transaction activity strengthens, another question becomes equally important: “How certain is my route to completion?”
This does not mean choosing expensive short-term finance simply for speed. Nor does it mean that every HNW buyer should use a private bank or bridging facility.
It means establishing the available routes before negotiations reach the point where timing becomes critical.
A buyer who already understands their conventional mortgage capacity, private-bank appetite, available liquidity and contingency funding can negotiate from a very different position from someone who begins the funding conversation after their offer is accepted.
For a £2m–£5m purchase, the important question may not be simply whether the client can obtain a mortgage. It is whether the entire funding route from exchange to completion has been mapped realistically.
What Does Funding Readiness Look Like for a Prime Buyer?
HNW property finance rarely fits neatly into a standard income-multiple calculation. Wealth can be spread across companies, investments, properties, partnerships and different jurisdictions.
The buyer may have considerable net worth while deliberately keeping relatively little cash uninvested. An entrepreneur may receive modest salary income while retaining substantial value in a business. An international family may hold assets across several currencies and countries.
Funding readiness therefore means understanding which elements of that balance sheet can realistically support the transaction and on what timetable.
A Prime Buyer Funding Readiness Review Should Establish:
- the maximum conventional large-loan mortgage available;
- whether private-bank lending offers greater flexibility;
- the amount of immediately available cash;
- equity held in the buyer's existing property;
- whether that equity can be accessed before the existing property is sold;
- the liquidity and composition of investment portfolios;
- whether securities-backed borrowing is available through the client's wealth-management relationships;
- whether regulated bridging is viable if completion must precede another property sale;
- the likely lender valuation and maximum sensible leverage;
- the realistic underwriting, legal and completion timetable.
Conventional Large-Loan Mortgages Can Still Be the Right Answer
A high-value property does not automatically require private banking.
Mainstream and specialist lenders can provide substantial residential mortgages where the client's income and circumstances fit their criteria. For borrowers with strong, readily evidenced earnings, this can provide straightforward and competitively priced finance without requiring a wider wealth-management relationship.
The difficulty arises where a client's financial strength does not present itself neatly through salary and conventional income.
A business owner may have significant retained profits but draw income conservatively. A partner in a professional firm may have complex annual distributions. An investor may derive wealth from assets rather than employment income.
In these circumstances, lender selection and presentation become critical. The cheapest advertised mortgage is of little value if the lender's underwriting model cannot recognise the way the client actually generates wealth.
When Private-Bank Lending Becomes Relevant
Private banks can take a broader view of a high-net-worth client's financial position. Depending on the institution and relationship, the assessment may incorporate investment assets, business interests, wider property holdings and overall net worth alongside conventional income.
This can be valuable for large interest-only borrowing or where the client's balance sheet is considerably stronger than their conventional affordability profile suggests.
Private banking is not automatically better, however. Some institutions require assets under management, broader banking relationships or minimum levels of investable wealth.
A buyer should therefore understand the complete proposition rather than comparing the mortgage rate alone.
What If the Buyer's Existing Property Has Not Sold?
This is one of the most common timing problems in the prime residential market.
A buyer may find the property they want before completing the sale of their current home. The existing property could contain substantial equity, but that capital remains inaccessible until the sale completes unless another funding route is arranged.
One option may be to increase borrowing against the existing property, subject to affordability and lender criteria. Another may be a mortgage structure that allows the buyer to carry both properties temporarily.
In appropriate cases, regulated bridging can provide a short-term route between the purchase of the new home and sale of the existing one.
Bridging should not be treated casually. Interest, fees, timing and the exit strategy all need to be modelled carefully. The property sale used to repay the bridge can take longer or achieve a lower price than anticipated.
The advantage of assessing the option in advance is not that the buyer has to use it. It is that they know whether a credible contingency exists if the ideal purchase appears before their existing sale completes.
Investment Wealth Can Create Liquidity Without Necessarily Selling Everything
Some HNW buyers hold the cash required for a property purchase inside investment portfolios.
Liquidating those investments may be perfectly sensible. In other circumstances, however, the timing could be unattractive, create tax consequences or disrupt a long-term investment strategy.
Depending on the client and institution, securities-backed lending can sometimes provide liquidity against an eligible investment portfolio. Private banks and wealth managers may offer facilities secured against qualifying assets rather than requiring the portfolio to be sold.
This introduces investment and leverage risks of its own, including the possibility of additional collateral requirements if portfolio values fall. It is therefore not simply a substitute for a mortgage.
For suitable clients, however, it demonstrates why prime property finance should be considered at balance-sheet level rather than looking only at the property being purchased.
International Buyers Have Another Layer of Timing Risk
International families purchasing London property can face additional practical steps that domestic buyers do not.
Income and wealth may need to be evidenced overseas. Source-of-funds documentation can involve multiple accounts or jurisdictions. Currency transfers need to be coordinated, and the lender may have specific requirements relating to the applicant's country of residence.
These are manageable issues when identified early. They become more difficult when a buyer has already agreed a short completion timetable.
For an international purchaser, funding readiness therefore includes preparing the evidential package — not merely establishing that sufficient wealth exists.
Why Buying Agents and Prime Estate Agents Should Care
The same issue matters to the professionals representing buyers and sellers.
A buying agent may identify the right property, negotiate an attractive price and secure the seller's attention, only for uncertainty around funding to weaken the client's position.
Prime estate agents face the reverse problem. A high offer is not necessarily the strongest offer if the buyer's route to completion has not been tested.
Mortgage and liquidity planning can therefore form part of the pre-offer process. The objective is not to produce a generic agreement in principle and declare the buyer “approved”. It is to establish how the transaction would actually be funded if the offer were accepted.
Funding Certainty Does Not Mean Borrowing at Any Cost
Speed can become disproportionately attractive when a buyer believes they may lose a property.
That is precisely when the financing decision needs discipline.
An expensive bridge should not replace a suitable long-term mortgage merely because it can complete more quickly. Equally, liquidating an investment portfolio solely to create the appearance of being a cash buyer may be unnecessary if appropriate secured finance is readily available.
Every funding route has a cost and risk profile. Interest rate, arrangement fees, early repayment charges, liquidity requirements, collateral risk and the reliability of the repayment strategy all matter.
The purpose of preparing early is to preserve choice. A buyer who begins structuring the finance before finding the property can compare those trade-offs calmly rather than making a major borrowing decision under pressure from an exchange deadline.
What the 34% Increase Does — and Does Not — Tell Us
One month's transaction data should never be treated as proof of a new property cycle.
London's market remains segmented. Price, property quality, location and seller expectations continue to determine how quickly individual homes transact. Prime London in particular remains a selective market after several years in which higher transaction costs and changing buyer sentiment placed downward pressure on prices.
The July data nevertheless provide an important early signal. Buyers are beginning to act in greater numbers even though pricing conditions remain relatively favourable.
If that continues, HNW purchasers may find that the best opportunities are no longer available indefinitely.
The market does not need to become expensive for funding readiness to matter. It only needs enough credible buyers to return that a seller no longer has to wait for the least-prepared purchaser.
How Willow Private Finance Can Help
Willow Private Finance works with high-net-worth individuals, entrepreneurs, international families and property investors arranging substantial residential finance across London and the wider UK.
For prime buyers, our role can begin before a property is selected. We can establish the realistic conventional mortgage position, explore private-bank appetite, assess available equity in other property and consider specialist or short-term funding where the circumstances justify it.
This is particularly valuable where the client has a complex balance sheet, large interest-only requirement, business income, investment assets, overseas earnings or an existing property that has not yet been sold.
The objective is not to maximise debt or encourage a buyer to transact faster than is appropriate. It is to give the client a clear understanding of how they could complete before they enter a negotiation.
In a London market where activity appears to be strengthening before prices have fully recovered, that certainty may become increasingly valuable.

High-value London purchases can involve several possible funding routes. Establishing those options before negotiating can reduce uncertainty once the right property is found.
Should I arrange a mortgage before offering on a prime London property?
It is often sensible to establish the funding structure before making a serious offer. For a high-value purchase, this means more than obtaining a generic agreement in principle. You may need to understand conventional mortgage capacity, private-bank appetite, available liquidity, lender valuation assumptions and any contingency funding required if another property has not yet sold.
What mortgage options are available for a £1 million or larger London property?
Depending on the borrower, options can include conventional large-loan residential mortgages, specialist mortgages and private-bank lending. Short-term regulated bridging may also be considered in appropriate circumstances. The right structure depends on income, assets, liquidity, required LTV, property type and the client's wider financial position rather than the property value alone.
Can a private bank lend against investments as well as the property?
Some private banks take a wider balance-sheet approach and may consider investment assets, business interests and wider wealth alongside the property. Certain institutions also offer lending secured against eligible investment portfolios. Requirements, collateral terms and wider banking relationships vary significantly, so these options need to be assessed on a case-by-case basis.
Can bridging finance help if my existing home has not sold?
Potentially. Regulated bridging can sometimes provide temporary funding where a buyer needs to complete a new residential purchase before selling their existing home. Bridging is short-term finance and can be more expensive than a conventional mortgage, so the expected sale, repayment strategy, interest and fees all need to be assessed carefully before proceeding.
Does having finance arranged make my London property offer stronger?
Funding readiness cannot guarantee that a seller will accept your offer, and price will remain an important consideration. However, a buyer who can demonstrate a credible and realistic route to completion may remove an important area of uncertainty for the seller and their agent. That can become more relevant where several buyers are interested in the same property.
