Large Mortgage Loans
As the amount you’re looking to borrow increases, a mortgage becomes less about choosing a standard product and more about finding a bespoke option based on the chosen property, income and amount required. Some lenders understandably restrict maximum loan sizes or take a more cautious approach as borrowing increases. Affordability models used by traditional high street lenders also do not always work well for large mortgage loans.
Anderson Harris provides whole-of-market mortgage advice for clients seeking large mortgages, including cases involving bonuses, investment income, business ownership, overseas earnings and substantial assets. We identify lenders prepared to consider the full circumstances rather than relying solely on standard automated criteria.

What Counts As A Large Mortgage Loan
Unhelpfully, there is no single, standard industry definition of a large mortgage loan. The shorthand term is generally used when the amount required moves beyond the lending levels handled routinely through standard affordability models, automated underwriting, and high street, mass market lenders.
That said, different products often become more noticeable once borrowing moves towards or beyond a million pounds. As a general rule, as loan sizes rise, mortgage processes become more complex. A lender may want more detailed evidence of income and assets, the application is likely to require manual underwriting, and the acceptable loan-to-value may decrease.
The property itself, if it is particularly high value, becomes a more significant part of any mortgage assessment. Valuations of prime or unusual homes may face more scrutiny, especially when there are relatively few comparable sales data points to reference.
For borrowers, this means the best mortgage isn't necessarily the product with the most visible headline rate. For large value loans, establishing which lenders genuinely have an appetite for the proposed amount is often equally important.
Why Large Loans Are Assessed Differently
It shouldn’t be a surprise that lenders assess large mortgages in more detail than standard residential products. This is understandable, as lenders take greater financial exposure to both the borrower and the property.
Manual underwriting often separates a standard mortgage from a higher-value loan. A high-value application is less likely to be assessed through the inflexible, automated scoring systems often associated with standard mortgages. Instead, an experienced underwriter may review the loan's overall circumstances to judge its feasibility. This creates scope for more detailed consideration of income, assets, and the borrower's repayment strategy, but it also means how the case is presented becomes more important.
Loan-to-value can also change as borrowing rises. A lender that is comfortable offering a particular percentage of a property's value on a smaller mortgage may impose a lower maximum when the loan is substantially larger. The deposit or equity available can therefore have a greater influence on which lenders are suitable.
Income assessment is another area where lender approaches differ significantly. Often, large mortgage repayments depend on a more complex income structure than a regular salary. Many borrowers will receive substantial parts of their income through bonuses, carried interest, dividends, partnership drawings or even foreign currency earnings.
Lenders will assess complex income in a myriad of ways, few of them straightforward. The same borrower can therefore receive very different affordability outcomes from different lenders. Clients with bonus and variable income may benefit from lenders that understand the structure and consistency of those earnings. At the same time, mortgages for self-employed and business owners can require careful assessment of salary, dividends, retained profits or wider business performance.
Valuation can create another complication. Automated valuation models rely heavily on comparable evidence. At the upper end of the market, where properties may be individually designed, extensively refurbished or rarely sold, comparable transactions can be scarce. A lender may therefore require a physical valuation and take a more cautious approach to the figure used for mortgage purposes.
These differences are also why a decline from one lender should not automatically be treated as evidence that the borrowing is unavailable. At this level, lender appetite, underwriting policy, and how income is assessed can vary considerably. This is why you should be careful if you're told the loan value is a problem when considering a mortgage. You may be speaking to the wrong lender. The team at Anderson Harris can help you explore the wider market.
Which Lenders Arrange Large Mortgage Loans
The market for larger borrowing is narrower than the market for standard residential mortgages, but there is still plenty of choice if you know where to look for options. While a limited number of mainstream lenders have specialist teams that can consider substantial loans, you can also turn to a wide range of specialist lenders, institutions, and private bank options.
Independent broker support can help you determine which part of the market fits your required amount, property, income profile, and available deposit or equity. It is tempting to assume a particular type of lender or product is necessary based on your loan size, but assumptions about product availability can prove limiting. If you are a high net worth borrower in particular, it certainly pays to shop around, explore the market as a whole and avoid being swayed by headline rates in isolation.
Finding The Right Large Loan
Large mortgage borrowing arises in a wide range of circumstances. The amount required may be significant, but the reasons behind it can vary widely. The good news is expert advice can help you navigate your particular circumstance.
Imagine buying a home in a prime city location with income made up of variable bonuses or deferred compensation, for example. The challenge, therefore, is often not whether you can afford a larger mortgage in practical terms. The question is whether your chosen lender gives sufficient credit to your earnings.
A homeowner refinancing a large loan at the end of a fixed-rate period may face a different problem. The lender that was comfortable with the original mortgage may have changed its appetite, affordability model or maximum loan parameters by the time the mortgage needs to be renewed.
Capital raising is another common requirement. A borrower with substantial equity in a high-value property might want to release part of that capital for a business, investment or other permitted purpose. The lender will consider both affordability and the proposed use of funds in this case.
Some borrowers have considerable investments or other assets but comparatively modest conventional income. Foreign currency income creates another layer of complexity. In all cases, selecting a lender with an appropriate approach to assessing affordability is vital.
How We Help Arrange A Large Mortgage Loan
We have established that large mortgage applications are not always straightforward. They benefit from preparation before they reach formal underwriting. Anderson Harris manages the process from the initial discussion through to completion.
1. We Understand Your Higher Borrowing Needs
Our large mortgage broker team starts with the property, amount required, and available deposit or equity. We then look at how your income and wider finances are structured. This gives us a clear picture of your requirements, which we can take to lenders.
2. We Identify Lender Appetite For A Larger Loan
We then search the market for lenders that will realistically consider the loan size and your circumstances. This helps avoid unnecessary applications to lenders whose criteria are unlikely to fit.
3. We prepare and present the case
Where appropriate, we discuss the application with underwriters and provide the supporting evidence needed to explain income, assets and the proposed borrowing structure.
4. We manage the application
Once the mortgage proceeds formally, we coordinate the process through underwriting, valuation and completion, dealing with lender queries and keeping you informed.

Large Mortgage Loans FAQs
-
The term ‘large mortgage loan’ is often used in the industry to describe borrowing large enough for lenders to move away from standard automated processes. Although lender approaches differ, this often becomes relevant around seven-figure borrowing.
-
The amount available depends on income, existing commitments, deposit or equity, the property and the lender's approach to affordability. For larger loans, some lenders also take a broader view of assets and overall financial circumstances. No single maximum applies across the market.
-
Deposit requirements vary. As loan sizes increase, some lenders reduce the maximum loan-to-value they are prepared to offer. This means a borrower seeking a substantial mortgage may need proportionately more equity than somebody taking a smaller loan, but there is no standard response.
-
Dedicated parts of the mainstream mortgage market, as well as specialist lenders and private banking institutions, all offer large loans. The best route depends on your borrowing needs, income structure, property, and available assets.
-
Loan size does affect the mortgage process, but it doesn’t necessarily mean they are harder to get. Higher loan amounts can result in manual underwriting, lower maximum loan-to-value ratios, and more detailed property valuations. Careful lender selection becomes more important.
-
Potentially. Lenders take different approaches to bonus income. Some average it over previous years, while others distinguish between guaranteed and discretionary payments. The consistency, history and structure of the bonus can all affect affordability.
-
Some lenders will consider a wider range of assets as part of your overall financial position, although approaches vary and income usually remains relevant to mortgage affordability. Clients with significant investments or other assets may have options beyond standard income-multiple lending.
-
There is no standard timeframe, but Anderson Harris can help prevent delay. Preparing the case thoroughly before application can help reduce avoidable delays.
-
A larger mortgage does not automatically mean a higher rate, although the range of lenders and products may differ from the standard mortgage market. We can help you assess the market for the best deal.
-
A decline from one lender does not necessarily mean other lenders will reach the same decision. Before making another application, it is usually sensible to understand why the first lender declined and identify lenders whose criteria better match the case.
