Hedge Fund Portfolio Manager Secures £2.4m Interest-Only Mortgage on £3.25m Home Using Performance-Linked Pay
A portfolio manager at a London multi-strategy hedge fund earned a £180,000 base salary, with the substance of his income arriving once a year as a contractual percentage of the performance fees on his book. He needed £2,400,000 for a £3,250,000 family home, structured interest-only so the fixed monthly cost sat within his base salary. Standard treatment of the payout supported nowhere near that figure; a clearing bank's large-loan team recognised it at 65% of a three-year average, £453,000 of income in total, and lent at roughly 5.3 times within a loan-to-income tier that can extend to 5.5 times.

Loan to Value (LTV)
Portfolio manager running a long/short equity book at a London-based multi-strategy hedge fund; nine years at the fund, the last five running his own book · Six-bedroom Arts and Crafts house, North London (Highgate) · £850,000 deposit · Interest-only, five-year fixed rate
Key constraint
On standard discretionary-bonus treatment at a standard multiple, recognised income supported barely two-thirds of the loan, and the higher loan-to-income tiers that could close the gap are often unavailable on interest-only at this LTV
Context
Space forced the move. The family's Victorian terrace in Highgate had fitted well enough when the children were small; with both now at secondary school it had run out of rooms, and a six-bedroom Arts and Crafts house half a mile away came up at £3,250,000. Selling the terrace released the £850,000 deposit, and staying local meant no change of schools. The client's wife runs an interior architecture practice; the mortgage sat in his sole name, and nothing in the income case relies on her earnings.
His income has the shape fund pay usually has. Nine years at a London multi-strategy hedge fund, the last five running a long/short equity book, on a modest £180,000 base salary, with an annual payout defined in his employment terms as a fixed percentage of the performance fee his book generates. The percentage never changes; the profit and loss (P&L) on the book does. His last three payouts were £450,000, £330,000 and £480,000, the middle year reflecting a period when part of the fund sat below its high-water mark.
What he wanted from the mortgage mirrored how he runs the book: a fixed monthly cost sized against the salary that arrives every month, and the freedom to cut the balance in large pieces when the payout lands. That is an interest-only structure, and it meant the case had to clear the income test and the product test at the same time.
The Challenge
The starting point was plain: at a standard multiple of around 4.5 times income, a £180,000 base supports roughly £810,000 of borrowing, around a third of the requirement. The payout had to carry the rest, and this is where the label matters. The percentage share is contractual, but the number it produces varies with performance, and to most lender criteria that makes it a discretionary annual bonus: the most cautiously treated category of variable pay.
The standard mechanics follow from the label. Many lenders may recognise 50% of a two-year average, working from the latest year where it is lower. His two-year average is £390,000 (£450,000 and £330,000); half of that is £195,000, and added to base the recognised income becomes £375,000, which at 4.5 times supports about £1,687,500. Lenders that cap recognised variable income at the level of base salary may arrive nearer £1,620,000 (£360,000 at 4.5 times). Against a £2,400,000 requirement, neither is close. The mechanics behind these treatments are set out in our article on how performance-linked pay affects affordability →
Closing a gap of that size takes movement on both parts of the calculation: the proportion of the payout recognised, and the loan-to-income (LTI) multiple applied to the recognised figure. Higher LTI tiers exist, but they are gated. Tiers of 5 to 5.5 times, and in some cases up to 6 times, may be available at higher income bands and moderate LTVs; several are restricted to capital-and-interest borrowing, and even where a tier survives, the interest-only multiple may be capped lower. The structure narrowed the field in parallel: ceilings for straight interest-only may sit at 60–75% LTV depending on the lender, the list of acceptable repayment vehicles differs from one lender to the next, and at £2,400,000 the application would be manually underwritten in any case, with tighter LTV bands and a documentation step-up. Most of the field failed on the income treatment, the multiple, or the interest-only rules; what remained was a short list, drawn from the part of the market covered in our guide to mortgages for hedge fund professionals →

Lender Strategy
The case rested on a distinction most published criteria do not draw: the difference between a bonus a committee decides each year and a payout a formula produces. A conventional discretionary bonus has no contractual anchor; nothing in the employment terms says what it will be. This client's payout has one. The percentage is fixed in his terms, the calculation is mechanical, and the only variable is the P&L of the book. Three years of payout statements, each reconciling the percentage to the fund's performance-fee figure for that year, evidence this in a way an underwriter can follow line by line.
On a standard application that distinction can disappear, because the payout still arrives once a year at a variable size and criteria bucket it accordingly. So the case was not submitted cold. It went first to the large-loan team of a top-five UK clearing bank (the part of the lender that reviews cases of this size by hand), with the documentary chain assembled in advance. On that review, both parts of the calculation moved. The payout was recognised at 65% of its three-year average, rather than the 50% of a two-year average that standard treatment may produce. And the loan was assessed within the lender's higher LTI tier, a tier that can extend to 5.5 times at this income level, and, unusually for the market, on interest-only at this LTV.
The arithmetic in full: the three-year payout average of £450,000, £330,000 and £480,000 is £420,000. Recognised at 65%, the payout contributes £273,000; added to the £180,000 base, recognised income becomes £453,000. £2,400,000 against £453,000 is roughly 5.3 times, inside the tier.

At a standard multiple of around 4.5 times income, a £180,000 base supports roughly £810,000 of borrowing, around a third of the requirement.
50% of the £390,000 two-year average plus £180,000 base = £375,000 recognised income; at 4.5 times, about £1,687,500.
65% of the £420,000 three-year average plus £180,000 base = £453,000 recognised income; at roughly 5.3 times, £2,400,000.
The same payout record throughout. Moving both parts of the calculation, the proportion recognised and the multiple applied, takes the borrowing from about £1,687,500 to the £2,400,000 the purchase required.
Please note: These figures are for illustrative purposes only. The actual amount you can borrow will depend upon your personal circumstances, credit profile, LTV, the lender's individual criteria and a full affordability assessment.
Neither move was a favour. The recognition percentage rested on the formula: a contractual share, unchanged in five years, evidenced across three payout cycles. The multiple rested on the profile: income at a level where premium tiers apply, an LTV inside the tier's ceiling, and a monthly commitment covered by base salary alone. The packaging existed to make both facts impossible to miss.
The interest-only structure sat within the same lender's criteria. Its ceiling for straight interest-only can run to just under 75% LTV, which accommodated the loan at just under 74%. Sale of the property was the primary repayment vehicle, supported by £850,000 of day-one equity, comfortably above the minimum-equity floors that may apply to that route in London. Lump-sum capital reductions are planned from future payouts inside the product's annual overpayment allowance. How these rules differ across lenders is covered in our guide to interest-only mortgages →
The application itself was packaged for manual underwriting: three years of payslips and P60s; the payout statement for each year; the employment terms setting out the percentage share; a letter from the fund confirming role, tenure and the book he runs; three months of bank statements and a full expenditure-and-assets picture. The covering note made one point above the others: the formula has not changed in five years, only its inputs have, and the base salary covers the proposed monthly commitment on its own.

A £2,400,000 interest-only mortgage was agreed at just under 74% LTV on a five-year fixed rate over a 25-year term, at roughly 5.3 times the £453,000 of recognised income, priced within the mainstream range for loans of this size. The monthly commitment sits inside the client's base salary with room to spare. A Decision in Principle (DIP) followed the large-loan conversation in eight working days; first call to credit-approved offer took a little over five weeks, reflecting manual underwriting at this size, and completion was set for late August, ahead of the new school term. The first lump-sum capital reduction is planned from the next payout round. For borrowing at this scale more broadly, see our guide to large loans (£1m+) →
Why This Matters for Similar Clients
Portfolio managers often assume the standard discretionary-bonus treatment, half of an average at four and a half times, is the most any lender will offer. For pay that genuinely is decided at discretion each year, the caution is understandable. But borrowing is the product of two numbers, the income recognised and the multiple applied to it, and for a contractual share of performance fees with a documented record, both may move: some lenders, particularly through the teams that review large loans by hand, may recognise a higher proportion of the payout and assess the loan within a higher LTI tier. Which lenders, at which income bands, LTVs and repayment structures, is criteria knowledge: the placement decision our article on why hedge fund income often needs specialist structuring works through in full.
What We Can Do for You
- Establish before any application how different parts of the market may read a performance-linked payout: the percentage recognised, the averaging window, and any cap against base salary
- Identify the lenders on our panel whose higher LTI tiers hold at your income level, your LTV and your repayment structure, and take cases of this size to their large-loan teams before submission
- Structure the monthly commitment around base salary, with capital reduced in lump sums as payouts arrive
- Package employment terms, payout statements, payslips and P60s so an underwriter can trace the formula to the cash it produced
FAQs
It can. Most lenders assess it under their variable-income rules and may recognise anywhere from 50% to 100%, depending on the averaging period, the track record and whether any cap against base salary applies. Where a case lands in that range depends as much on the evidence as on the income.
Most criteria read it as a discretionary annual bonus, the most cautiously treated category of variable pay. Where the percentage share is contractual and evidenced over several years, some lenders, often through large-loan or specialist teams, may recognise a higher proportion than the standard default.
Potentially. Some lenders operate tiers of 5 to 5.5 times, and in some cases up to 6 times, gated on income level, LTV and sometimes repayment type. Several premium tiers may be restricted to capital-and-interest borrowing, so on interest-only the available multiple can be lower.
Potentially. Interest-only ceilings may sit anywhere from 60% to 80% LTV depending on the lender, with minimum income thresholds and a defined list of acceptable repayment vehicles. Affordability is still assessed in full whatever the repayment structure.
Payslips and P60s showing each payment, the employment terms setting out the percentage share, and the fund's payout statements reconciling each year's figure to the performance behind it. A letter from the fund confirming role and tenure completes the picture.
