A client with substantial investments and valuable property may appear to have considerable borrowing capacity. However, if part of the investment portfolio is already pledged to support a Lombard loan or other securities-backed facility, the client’s accessible liquidity may be materially lower than their headline asset position suggests.
Willow works with advisers through its wealth manager and financial adviser partnership service. This article completes Willow’s investment, liquidity and borrowing guide series for IFAs and wealth managers.
Willow’s role is to assess mortgages and property-backed finance. We do not advise on the suitability of a portfolio-backed facility, the client’s investment allocation or which investments should be retained or sold. Those matters remain with the client’s wealth manager and other appropriately qualified advisers.
First Map the Existing Portfolio-Backed Facility
“The client has a Lombard loan” is not enough information for a property-finance assessment. The facility agreement, current balance and collateral position determine how the debt may behave.
The relevant information may include:
- the current amount drawn and total facility limit;
- the value of eligible pledged investments;
- the current loan-to-value or collateral ratio;
- the facility’s maintenance or collateral-call thresholds;
- which investments are eligible and their applied lending values;
- whether the portfolio is concentrated in a particular company, sector or currency;
- whether interest is serviced or added to the balance;
- the lender’s ability to change eligibility or advance rates;
- the time allowed to provide additional collateral or repay debt;
- the lender’s rights to sell investments following a breach; and
- any maturity date, review date or right to demand repayment.
The client’s wealth manager and portfolio-facility provider should explain these terms. Willow needs enough factual information about the existing debt to assess the proposed property borrowing accurately, but does not interpret or recommend the investment facility.
Investments pledged to a lender may still appear on a client’s asset statement, but they should not automatically be treated as unencumbered, immediately accessible liquidity.
Where Can the Two Borrowing Risks Meet?
The facilities may have separate lenders and separate security. One may be secured against investments and the other against property. That does not make their risks independent.
Reduced Capacity to Meet a Collateral Call
If investment values fall, the portfolio lender may require additional collateral or partial repayment. Further property borrowing may absorb income or cash reserves that could otherwise have been used to respond.
Property Payments Continue During a Market Fall
Mortgage interest and capital payments do not disappear because the investment portfolio has fallen. The client may therefore need to support both a property commitment and an unexpected portfolio-facility demand at the same time.
The Same Assets May Support More Than One Assumption
A client may view their investments as the eventual repayment source for a property facility while those investments already support another lender’s security. The property-finance plan must recognise the existing lender’s priority and any restrictions on withdrawals.
Interest Can Increase Both Debts
Where interest is added to either facility rather than serviced, outstanding debt can increase without an immediate monthly payment. A cash-flow assessment that records only current payments may therefore understate the client’s growing liability.
A Planned Exit May Become Less Attractive
If repayment requires investments to be sold, a market fall could force the client to realise assets at an unfavourable time. If repayment relies on selling property, a slower transaction or reduced sale price could extend the period during which both debts remain outstanding.
Headline Wealth Is Not the Same as Available Liquidity
The Headline Position
The client owns a substantial investment portfolio and high-value property. Total assets materially exceed the proposed borrowing.
The Usable Position
Part of the portfolio is pledged, investments may fall in value, property is illiquid and both lenders may expect repayment or additional funds within different timescales.
A useful assessment separates the client’s position into:
- Unencumbered liquid assets: cash or investments not already pledged and available without lender consent;
- Encumbered investments: assets supporting the portfolio-backed facility;
- Property equity: value remaining after existing secured borrowing, subject to valuation and sale costs;
- Committed expenditure: mortgage payments, facility interest and other contractual obligations;
- Contingent liquidity demands: potential collateral calls, tax liabilities, capital calls or other known requirements; and
- Repayment resources: assets or income genuinely available to clear the proposed property borrowing.
This does not require Willow to judge the investment portfolio. It allows the property-finance assessment to begin from the client’s net, usable position rather than gross asset values.
Stress-Test Both Facilities Together
The purpose of a combined stress test is not to forecast what markets or property values will do. It is to identify whether a plausible adverse event could create an unmanageable demand for cash.
Illustrative Example Only
Assume a client has an eligible pledged portfolio valued at £4 million and portfolio-backed debt of £1.4 million. The current facility ratio is therefore 35%.
If the facility required action at a hypothetical ratio of 45%, a 25% fall in the eligible portfolio would reduce its value to £3 million. With the debt unchanged, the ratio would rise to approximately 46.7%.
Now assume the client has also taken £750,000 of property-backed borrowing. That property loan does not necessarily change the portfolio facility’s ratio. However, it increases total indebtedness and may use income or cash that could otherwise help meet the collateral demand.
The figures are hypothetical and do not represent any lender’s terms. Actual advance rates, collateral values, thresholds and enforcement provisions are determined by the relevant facility agreement.
A meaningful review might test:
- a 10%, 20% and 30% fall in eligible portfolio value;
- a reduction in the lending value assigned to a concentrated holding;
- higher interest costs on variable-rate borrowing;
- six or twelve months of delay to the planned property-finance exit;
- a lower-than-expected property sale price;
- the simultaneous arrival of a tax liability or capital call; and
- whether the client could meet both facilities’ requirements without a distressed sale.
Four Questions the Combined Stress Test Should Answer
- How much genuinely unencumbered liquidity remains after completion?
- Could the client meet a portfolio collateral call while maintaining property payments?
- Would either facility have to be repaid by selling an asset during adverse conditions?
- What happens if the intended repayment event is delayed or produces less cash than expected?
What May a Property Lender Examine?
Existing portfolio-backed debt should normally be disclosed as part of the client’s liability position. Depending on the proposed finance, the property lender may examine:
- the outstanding balance and facility limit;
- current interest payments and whether interest is being capitalised;
- whether the facility is repayable on demand or has a fixed maturity;
- the effect of existing debt on the client’s income and affordability;
- the value and accessibility of assets claimed as reserves;
- whether investments proposed as an exit are already pledged;
- the purpose of the further borrowing;
- the property value, existing charges and proposed loan-to-value;
- the client’s income, expenditure and other liabilities; and
- how the new facility would be repaid under both expected and adverse conditions.
For regulated mortgages, FCA rules require lenders to consider committed expenditure as part of the affordability assessment. Existing secured and unsecured credit commitments can therefore be relevant even where the client has substantial assets.
Private-bank and specialist lending approaches may differ, particularly for high-net-worth clients. Nevertheless, a lender’s flexibility should not be interpreted as a reason to omit existing debt or present pledged assets as freely available.
Comparing the Property-Finance Structures
A Conventional Mortgage or Remortgage
A longer-term mortgage may provide greater repayment certainty than short-term finance. However, affordability, early repayment charges, completion times and the effect of existing liabilities must be considered.
A Further Advance
Additional borrowing from the existing mortgage lender may avoid disturbing the first mortgage. The lender will still assess the purpose, affordability, property value and the client’s wider debt position.
A Second-Charge Mortgage
A second charge can preserve an existing first-mortgage arrangement, but it creates another secured commitment against the property. The client must understand the combined monthly cost and the consequences of failing to maintain either facility.
Short-Term Property Finance
Bridging finance may be relevant where the client has a defined short-term requirement and credible repayment event. It becomes more concerning where repayment depends on the same investments already exposed to a potential collateral call.
Reducing or Replacing Existing Borrowing
In some cases, the correct property-finance conversation may involve restructuring rather than simply adding debt. Whether an existing portfolio facility should be reduced or retained is not a decision for Willow, but the client’s advisers should understand how each proposed structure affects the overall position.
When Could Further Borrowing Compound the Risk?
Further property borrowing deserves particular caution where:
- the pledged portfolio is already close to a maintenance threshold;
- the portfolio is concentrated in a small number of securities, sectors or currencies;
- interest on the existing facility is being added to its balance;
- the client has limited unencumbered cash outside the pledged portfolio;
- the property facility’s repayment plan depends on selling pledged investments;
- the client expects investment returns to cover both facilities’ borrowing costs;
- the new borrowing would fund another illiquid or long-dated commitment;
- both facilities have variable interest costs;
- a market fall could coincide with a property completion, tax payment or capital call;
- the property facility requires refinancing rather than repayment from a defined source; or
- the client’s strategy assumes that lenders will extend terms or relax collateral requirements.
A property loan can appear conservative against the property while still weakening the client’s ability to respond to a problem elsewhere on their balance sheet.
Keep the Professional Responsibilities Clear
A coordinated case should preserve the distinction between investment advice and lending advice.
The Wealth Manager
The wealth manager assesses the investment portfolio, concentration, liquidity strategy and the suitability of retaining, selling or pledging investment assets.
The Portfolio-Facility Provider
The provider confirms eligible collateral, current facility utilisation, maintenance thresholds, interest arrangements and the contractual consequences of a fall in collateral value.
Willow Private Finance
Willow assesses the proposed mortgage or property-backed facility, including lender appetite, affordability treatment, security, cost, term and repayment strategy.
The Client’s Legal and Tax Advisers
Legal and tax advisers consider facility documentation, security, ownership structures, tax consequences and any conflicts between the proposed arrangements.
Finance being available does not establish that increasing the client’s total leverage is suitable. Conversely, the existence of portfolio-backed debt does not automatically prevent property borrowing. The answer depends on the combined position.
When to Involve Willow
An early, anonymous discussion may be worthwhile where:
- the client wants a mortgage but already has a substantial Lombard facility;
- the proposed deposit or repayment strategy involves pledged investments;
- the client’s bank has treated their investment portfolio as unavailable or discounted its value;
- portfolio-facility interest is being rolled into the balance;
- the client wants to preserve an existing mortgage while raising further capital;
- the proposed borrowing is short term and requires a clearly evidenced exit;
- the client has significant gross assets but limited unencumbered liquidity;
- a complex ownership or security structure requires specialist lender assessment; or
- the adviser wants to understand how a property lender may treat the existing facility before the client commits to a transaction.
The initial outline does not need to identify the client. The proposed property transaction, required amount, property value, existing mortgages, approximate portfolio-facility balance, accessible liquidity and intended repayment source will usually establish whether a fuller assessment is worthwhile.

Frequently Asked Questions
These answers provide general information about property-finance assessment. Individual lender policies and facility terms vary.
Does portfolio-backed debt prevent a client from obtaining a mortgage?
Not automatically. A lender will consider the facility balance, payment obligations, available income, purpose of the new borrowing and the client’s wider liabilities. The existing debt may reduce affordability or require a more detailed underwriting assessment.
Can property borrowing increase the risk of a margin or maintenance call?
Property borrowing does not necessarily alter the portfolio facility’s collateral ratio directly. It can, however, reduce the client’s spare income and accessible liquidity, making a future collateral call harder to meet.
Will a property lender count Lombard interest as an existing commitment?
Potentially. Treatment varies between lenders and structures, but existing credit and contractual commitments can be relevant to affordability. A lender may also consider interest that is being added to the balance rather than paid monthly.
Can the investment portfolio be used as the repayment strategy?
Possibly, but pledged investments cannot be treated as freely available without considering the existing lender’s security, withdrawal restrictions and the effect of a market fall. The property lender will decide whether the proposed repayment strategy is acceptable.
What can Willow assess in a case involving portfolio-backed debt?
Willow can assess the proposed mortgage or property-backed facility, its likely affordability treatment, security, costs, term and repayment strategy. Willow does not advise on the suitability of the client’s investments or portfolio-backed facility.
