Mortgages structured around bonus income, deferred compensation, and complex remuneration
Whether you're an analyst buying your first flat, a VP upsizing, or an MD securing a large loan on a family home, we understand how your income works — and which lenders treat it most favourably.
W H Y A S P E C I A L I S T B R O K E RWhy Investment Bankers Need a Specialist Mortgage Broker
You earn well. You'll probably be fine. That's what most bankers assume — and in many cases, they're right. But for a profession where bonuses routinely exceed base salary, the standard mortgage process can produce results that bear very little resemblance to your actual earning power.
The problem isn't whether lenders accept bonuses — most do. The problem is how they calculate them. Some average over two years. Some cap at 50% of base salary. Others will use a higher percentage but only with three years of history at the same employer. Two lenders looking at the same P60 can produce borrowing figures that differ by hundreds of thousands of pounds.
Then there's the question of which income they'll consider at all. Deferred compensation, sign-on bonuses, guaranteed bonuses that roll into discretionary awards after year one, USD-denominated pay — each of these introduces a policy question that most brokers don't know to ask.
We work with investment bankers across the career ladder — from analysts at bulge brackets buying in zones 1–3, to MDs and sector heads purchasing £2m+ family homes. We know the lender landscape for bonus-led income, we've seen the policy variations first hand, and we can give you a clear answer on what's achievable, usually within the first call.

Analysts and Associates
If you're employed on PAYE, lenders will take your base salary at face value. The variable that matters is how they treat your bonus.
Most mainstream lenders average bonus income over the last two years and then use a percentage of that average — commonly 50 to 75%. Some will cap the bonus element at the level of base salary, which means if you're earning £70k base with a £120k bonus, a significant portion of your income simply disappears from the affordability calculation.
The key variables for analysts and associates are: how many years of bonus history the lender requires (usually two, though some accept one with an employer confirmation letter), what percentage of the average they'll use, and whether they apply a cap relative to base salary.
At this level, the single biggest factor in borrowing power is almost always lender selection. We've seen cases where switching from one mainstream lender to another — both perfectly reputable — adds significantly to borrowing capacity on the same income.
If you've recently moved firms and don't yet have two years of bonus history at your new employer, the picture narrows further. Some lenders require continuous bonus history from the same employer, while others will accept a track record across employers as long as the role and sector are comparable. We know which lenders take the latter approach, and can often find a route even with only one year at the current firm.
Managing Directors and Senior Leadership
At MD level and above, the income picture often becomes more complex. You may have a combination of base salary, discretionary annual bonus, deferred compensation (paid in cash or stock over two to three years), long-term incentive plans, and potentially equity stakes or co-investment returns.
Lenders don't treat all of these equally. Base salary and cash bonus are the most straightforward. Deferred compensation is harder — some lenders will consider the vested portion, but most are cautious about unvested awards. LTIPs are typically excluded from mainstream affordability calculations entirely.
The practical implication is that for very senior bankers, assessed income can be significantly lower than actual income. This is where structuring matters: interest-only arrangements, private bank options, and careful lender selection can close the gap between what the affordability model produces and what you actually need.
At this level, we often present two or three lender options — typically a mainstream large-loans team and a private bank — so you can compare on rate, flexibility, and total cost. The right answer depends on the specific numbers.
Deferred Compensation and Restricted Awards
From MD level, a growing proportion of your bonus is likely to be deferred — paid out in cash, stock, or fund units over two to three years rather than as an immediate lump sum. By the time you reach MD, deferred comp can represent 30 to 50% of your total variable pay.
This creates a specific problem for mortgage affordability: income that is contractually owed to you, and that you can reasonably expect to receive, simply doesn't exist in the eyes of most mainstream lenders. They want to see income that has been paid to you and appears on a payslip or bank statement. Unvested awards sitting in a deferred bonus pool, restricted stock account, or co-investment vehicle are typically excluded.
There are exceptions. Some lenders will consider vested deferred awards — i.e. tranches that have already converted to cash or unrestricted stock — as part of your income, provided you can evidence the receipt. A small number of private banks will take a view on unvested awards if the vesting schedule is clear and the firm is well-known. And where you have a multi-year track record of deferred comp vesting consistently, we can present that pattern as sustainable income to underwriters who are willing to look beyond the current payslip.
We structure these cases by separating the income into components: base salary, cash bonus, vested deferred comp, and unvested deferred comp. We then match each component to the lender most likely to accept it. In some cases, the best outcome is a mainstream lender for the core income plus a top-up facility or different structure to bridge the gap.
The best outcomes at this level typically come from lenders with clear frameworks for senior banking roles. These lenders understand that a VP or Director at a major investment bank has a predictable earnings trajectory, even if the bonus fluctuates with market conditions. They'll assess the income on a sustainability basis rather than applying rigid mechanical caps.
What usually matters most at this stage: a consistent multi-year bonus track record (two or three years), stability in role and employer, and a borrowing requirement that is proportionate to overall income. If all three are present, there are lenders that will use a meaningfully higher proportion of your bonus than the market default.
Lateral moves are common at VP and Director level — and they can temporarily disrupt the bonus evidence that lenders rely on. If you've recently moved from one bank to another, you may have only one bonus at the new firm, and your sign-on bonus may have been structured as guaranteed for year one only. Some lenders will treat the guaranteed element as sustainable income; others won't. And if your previous firm's bonus and your new firm's bonus are materially different, averaging across the two can either help or hurt. We see this scenario regularly and know which lenders handle it best.
How bonuses are actually calculated for mortgage affordability →
Vice Presidents and Directors
At VP and Director level, bonuses typically make up a larger proportion of total compensation — often 50 to 100% or more of base salary. This is where lender policy differences become most pronounced.
The challenge is straightforward: your income is strong and consistent, but because the variable component is so large relative to the fixed component, many lenders either discount it heavily or cap it.
B O R R O W I N G P O W E RHow Much Can an Investment Banker Borrow?
Most investment bankers with clean credit and manageable outgoings can expect to borrow between 4.5 and 5.5 times their assessed income. Some lenders offer enhanced multiples — up to 6x — for recognised professionals at certain income thresholds and LTV levels.
But the income multiple is only part of the equation. What matters more is what the lender counts as "income" in the first place. A 5x multiple on an assessed income of £250k gives you £1.25m. The same 5x multiple on an assessed income of £350k — because the lender treats bonus more generously — gives you £1.75m. Same person, same P60, half a million pounds difference.
This is why we never quote a headline multiple without running the affordability calculation through the specific lender's model. The real number depends on which income components the lender accepts, how they calculate them, and how their stress-testing model works.
M O R T G A G E S T R U C T U R E SStructures for Investment Bankers
Interest-Only
Interest-only can be powerful for investment bankers, particularly if your income is bonus-heavy and you want to keep monthly commitments low while using annual bonuses to make capital repayments. Many lenders offer interest-only on the first portion of the loan — typically up to 75% LTV — with the remainder on repayment.
The catch: interest-only requires a credible repayment strategy. For most of our IB clients, this means demonstrating that future bonus income, investments, or eventual property sale will cover the capital. Some lenders are more pragmatic than others about what they'll accept as a repayment vehicle.
Offset Mortgages
If you're holding substantial cash — whether from accumulated bonuses, a sign-on payment, or deferred compensation that's just vested — an offset mortgage lets you reduce the interest you pay without locking the money away. Your savings sit in a linked account and offset your mortgage balance, so you pay interest only on the net amount.
The rate on an offset product is typically slightly higher than a standard fixed rate, but the net effect can be meaningful if you're parking £100k+ alongside the mortgage. It's particularly useful for bankers who receive large lump sums annually and want to deploy them efficiently without making irreversible capital repayments.
F O R E I G N C U R R E N C YMortgages with USD Income
Many investment bankers in London are paid in US dollars, either because they work for a US-headquartered bank or because their bonus is denominated in USD. Some firms pay base in GBP and bonus in USD. Others pay everything in dollars.
Only a small number of UK lenders accept foreign currency income, and each applies a different 'haircut' — a percentage reduction to account for exchange rate risk. These haircuts typically range from 10 to 25%, and the variation between lenders is significant. On a $300k salary, the difference between a 10% haircut and a 25% haircut is $45k of assessed income — which translates to roughly £150k+ in borrowing capacity.
We model affordability across all the major lenders that accept USD income, running parallel scenarios at different haircut levels so you know exactly where you stand before we submit anything. For bankers with both GBP and USD components, we structure the application to maximise the proportion assessed in sterling.

Private Bank vs High Street
Our default position is the same as for all our clients: if it works with a mainstream lender, go mainstream. The rates and fees are lower. High street large-loans teams have become significantly more sophisticated in how they handle complex income, and many now have established frameworks for investment banking professionals.
Private banks come into play when mainstream options genuinely can't accommodate what you need. That might mean: fully bespoke income assessment for very complex remuneration, interest-only on the full loan amount, very high LTV at large loan sizes, or lending against assets rather than income. If you need that flexibility, a private bank may be worth the premium.
But the premium is real. A private bank charging 0.5% more on a £1.5m mortgage costs you £7,500 a year in additional interest. Unless the flexibility justifies that premium — and sometimes it does — you're better off on the high street.
We'll always show you both options when both are viable. An informed decision based on a real comparison is always better than being pushed toward one route by a broker who doesn't have access to the other.

Timing Your Mortgage Around Career Changes
Investment banking careers move fast. Promotions, lateral moves, sign-on bonuses that convert to discretionary after year one, relocations between offices — each of these can affect how a lender assesses your income.
Recently promoted
If you've just been promoted from Associate to VP (or VP to Director), your bonus history may not yet reflect your new earning level. Some lenders will average your last two years of bonus, which includes the lower pre-promotion figure. Others will weight more recent income or accept an employer letter confirming your new compensation band. Timing matters — applying just after your first post-promotion bonus has landed gives you the strongest position.
Recently changed firms
If you've moved banks, you may have a gap in bonus history at the new employer. Some lenders require two years of bonus history from the same employer, which can be restrictive. Others will accept a track record across employers as long as the role and sector are comparable. A sign-on bonus can sometimes bridge the gap, but treatment varies.
Relocating to London
If you're transferring from a US or European office to London, the combination of foreign currency income, thin UK credit history, and unfamiliarity with the UK mortgage process can slow things down. We handle relocations regularly and can often pre-brief underwriters before you arrive.

F A Q sFrequently Asked Questions
-
Yes, though treatment varies significantly. Most mainstream lenders will include a proportion of your bonus — commonly 50 to 75% of a two-year average. Some apply caps relative to base salary, while others take a more holistic view for senior banking roles. The difference between lenders on the same income can be hundreds of thousands of pounds in borrowing power. We match your income profile to the lender that treats it most favourably.
-
Most lenders want to see at least two years of bonus history, evidenced through P60s and payslips. Some will accept one year with a supporting employer confirmation letter, particularly if you're at a well-known institution and the bonus is consistent with your role level. If you've recently changed firms, a track record across employers in comparable roles can sometimes satisfy the requirement.
-
It depends on the terms. Guaranteed bonuses that have been paid and appear on your payslip are generally accepted. However, sign-on bonuses that convert to discretionary awards after year one may be treated more cautiously. Lenders will want to understand whether the bonus is recurring or one-off — and one-off payments are typically excluded from ongoing affordability calculations, though they can contribute to your deposit.
-
It depends on whether it has vested. Deferred comp that has already converted to cash or unrestricted stock and been paid to you is treated like any other income — you'll need payslips or bank statements showing receipt. Unvested awards sitting in a deferred bonus pool or restricted stock account are excluded by most mainstream lenders, even if the vesting schedule is clear and the firm is well-known. Private banks are sometimes more flexible, particularly where the unvested amounts are substantial. Where you have a multi-year track record of deferred comp vesting consistently, we can present that pattern to lenders willing to look beyond the current payslip. We structure these cases by separating income into components and matching each to the right lender.
-
Yes. Several UK lenders accept USD income, but each applies a currency haircut — typically reducing the income they'll use by 10 to 25% to account for exchange rate risk. The variation between lenders is significant, and on a large income the difference can translate to £150k+ in borrowing capacity. We model affordability across all major lenders that accept foreign currency income and structure the application to maximise what they'll count.
-
Our default is high street if it fits — the rates and fees are lower. Mainstream large-loans teams are now very capable with bonus-led income. Private banks make sense when you need flexibility that mainstream lenders can't offer: fully bespoke income assessment, interest-only on the full loan, very high LTV at large loan sizes, or lending against assets. We'll always show you both options so you can make an informed comparison.
-
We'll give you indicative figures the same day as our first call — usually within a few hours. Once we have your documents (typically P60s, recent payslips, bonus award letters, and bank statements), we run a Decision in Principle within 24 hours.
-
In many cases, yes, but timing matters. If your first post-promotion bonus hasn't landed yet, lenders will assess you on historic income — which may understate your current earning capacity. Some lenders will accept an employer letter confirming your new compensation band. Others will weight more recent income. We know which lenders are flexible on this and can advise on the best time to apply.
-
Typically between 4.5 and 5.5 times assessed income, with some lenders offering up to 6x for recognised professionals at certain income and LTV thresholds. But the headline multiple matters less than what the lender counts as income. A 5x multiple on £250k of assessed income gives you £1.25m. The same 5x on £350k — because the lender treats bonus more generously — gives you £1.75m. We run the full calculation through lender-specific models to give you an accurate figure, not a headline.
-
For standard residential mortgages: no fee on loans above £500k, fixed fee of £500 for loans between £250k and £500k, and £1,000 for loans below £250k. For specialist cases — which includes foreign currency income, expatriate or overseas mortgages, Ltd company mortgages, and government schemes — there is a fixed fee of £1,000 at all loan sizes. Many investment banking cases involving USD pay or complex structures will fall into the specialist category. We'll always confirm which fee applies in the first meeting, before any work begins.
