Large mortgages
Higher-value borrowing requires a more considered approach.
Large mortgage applications can involve more detailed underwriting, higher-value properties, complex income and a wider range of lender types. Our advisers help structure and manage these cases from the outset.

Higher-value lending
Larger loans can change the way lenders assess an application.

The larger the borrowing requirement, the more important lender appetite and case structure can become.
Mainstream lenders may be able to provide significant mortgage loans, but maximum loan sizes, affordability models and underwriting approaches differ substantially from lender to lender.
In other circumstances, specialist lenders or private banks may provide a more appropriate route, particularly where the client's income, assets or wider financial position require more bespoke consideration.
Underwriting
What matters in a large mortgage application.
Higher-value mortgage cases often require lenders to take a more detailed view of the applicant, property and overall financial position.
01
Income structure
Larger mortgages can involve salary, bonuses, commissions, dividends, retained profits, partnership income or multiple income sources.
02
Loan size
As borrowing increases, lender appetite and underwriting approach can change significantly, particularly at higher loan values.
03
Loan-to-value
The relationship between the loan and property value can influence lender choice, pricing and the level of underwriting required.
04
Assets & liquidity
Some lenders, particularly private banks, may take a broader view of a client's assets, liquidity and overall financial position.
05
Residency & overseas income
International residency, overseas income and foreign assets can affect which lenders are able to consider the application.
06
Property
High-value, unusual or non-standard properties may require lenders with more flexible property criteria or valuation approaches.
Lender strategy
The right lending route depends on more than the loan amount.
Large mortgages can be arranged through several different parts of the lending market. The appropriate route depends on the client's income, assets, property, borrowing level and wider circumstances.
Our role is to understand the case before approaching lenders, rather than assuming that the largest loan automatically requires a private-bank solution.
Discuss your borrowingMainstream lenders
Major banks and building societies may consider substantial mortgage borrowing where the case fits their affordability, income and property criteria.
Specialist lenders
Specialist lenders can sometimes provide greater flexibility where income, residency, property or the overall application falls outside mainstream criteria.
Private banks
Private banks may consider higher-value borrowing within the context of a client's wider financial position, assets and banking relationship.


Complex income
Higher earnings do not always mean straightforward underwriting.
Higher-value clients can have income structures that do not fit neatly into a standard salary multiple. Bonuses, commission, partnership income, dividends, retained profits and overseas earnings may all require different lender treatment.
Different lenders may use different proportions of variable income or assess company and partnership earnings in different ways. Understanding those differences can materially affect the borrowing position.
Private banking
Some cases require a broader financial conversation.
Private-bank underwriting can look beyond a conventional mortgage application.
Depending on the institution, the bank may consider wider assets, investments, liquidity, business interests and the broader client relationship alongside the property and mortgage requirement.
Different private banks target different client profiles, which means lender selection can be particularly important before an application or enquiry is made.

How we work
Structure the case before approaching the lender.
Large mortgage cases can benefit from preparation before a formal application is made. Our team works through the financial and property details before determining the appropriate lending route.
Understand the requirement
We begin by understanding the property, loan size, income structure, assets, liabilities and wider financial circumstances behind the borrowing requirement.
Assess the lending routes

Approach the lender
Once an appropriate route has been identified, we prepare the application and supporting documentation around the lender's requirements.
Manage underwriting
Our adviser and administration team remain involved throughout underwriting, valuation, lender queries and the mortgage offer process.
Complete
We continue to support the case through the final stages of the transaction and mortgage completion.

Lender appetite becomes increasingly important at higher values.
Maximum loan sizes, affordability models and underwriting appetite vary significantly. Our lender access includes major banks, building societies, specialist mortgage providers and private banks.

Private banks may be relevant where borrowing is particularly substantial or where the client's wider assets, income, investment position or financial circumstances benefit from a more bespoke approach.
04Can bonuses and commission be used for affordability?
+

Some lenders may consider retained profits or take a broader view of company performance when assessing company directors, although this varies significantly between lenders.

Can I borrow against a high-value or unusual property?
Potentially. The property's value, construction, location, condition and marketability will all be relevant. Some lenders have greater appetite for high-value or non-standard property than others.
