Navigating the mortgage landscape as a high net worth (HNW) or ultra-high net worth (UHNW) borrower isn’t always straightforward. Despite significant wealth, many clients find their income structures, assets, or global tax arrangements make traditional mortgage approvals a challenge.

So, what are lenders really looking for in 2025 when it comes to large mortgages for affluent individuals?

It’s Not Just About Your Payslip

Private banks and specialist lenders understand that HNW clients often don’t earn traditional income. Instead, they look at the full picture:

• Assets under management (AUM): Investments, savings, and portfolios.
• Business ownership: Shareholdings, dividends, and retained profits.
• Global income: Including foreign currencies or offshore earnings.
• Property wealth: Buy-to-let portfolios or commercial holdings.

In 2025, the ability to evidence liquidity and long-term wealth is often more persuasive than simply proving salary multiples.

What Are the Key Lending Considerations?

Here’s what lenders will weigh up before approving large mortgages in today’s market:

• Track record of wealth: Are you consistently generating or holding significant value over time?
• Exit strategy: Especially for interest-only or short-term loans—how will the debt be repaid?
• Risk profile: Including jurisdiction, source of wealth, and exposure to volatile markets.
• Client profile: Are you a long-term relationship client or new to the bank?

Many private banks also offer relationship-led lending, where your overall value to the institution influences flexibility on rate, term, or structure.

Bespoke Lending Structures Are Common

Standard mortgage products rarely suit HNW clients. In 2025, we’re seeing greater demand for:

• Interest-only loans to preserve capital or manage cash flow.
• Asset-backed lending, where portfolios or shares are used as security.
• Foreign currency mortgages to align with income or asset base.
• Cross-collateralised deals across multiple properties or jurisdictions.
• 
  

At this level, lending is strategic—not transactional.

How to Strengthen Your Position as a Borrower

To maximise your options, we recommend:

✅ Preparing detailed wealth overviews and balance sheets
✅ Involving your accountant or family office early
✅ Clarifying your objectives (e.g., leverage vs. liquidity)
✅ Being transparent about any offshore structures or trusts

Specialist mortgage brokers can structure deals around your wider profile—not just what fits in a bank’s online portal.
