Thu 19 Mar 2026

CASE STUDY:
£4.5m PRIVATE BANK MORTGAGE FOR A PRIME SURREY PROPERTY AND A COUNTRY HOME ACQUISTION

As high net worth buyers continue to prioritise lifestyle flexibility, private banks are playing an increasingly important role in structuring complex, multi property purchases. This case study highlights how a £4.5 million facility enabled the acquisition of a Prime property in Walton on Thames/ Weybridge, alongside a countryside retreat.

Client Profile

The client was a UK based entrepreneur with significant net worth, although much of their capital was tied up in business ventures. Their income structure included dividends and international earnings, making it difficult for traditional lenders to assess affordability.

As a result, a private banking solution was required to reflect the full strength of the client’s financial position.

Property Acquisition Strategy

The client’s objective was to secure two complementary properties that would support both work and lifestyle needs.

Prime Surrey Residence £2.5m

Located in either Weybridge or Walton-on-Thames, the chosen property provided excellent access to London, strong schooling options, and long term capital growth potential.

Country Home £2m

The second purchase was a country home within one to two hours of London, offering privacy, outdoor space, and a setting suited to weekends and family time.

Financing Structure £4.5m Private Bank Facility

A private bank delivered a tailored lending solution that supported both acquisitions within a single structure.

Cross collateralised lending

Both properties were linked within one facility, allowing for greater borrowing efficiency and a more strategic use of equity.

Interest only structure

The mortgage was arranged on an interest only basis, helping the client to maintain lower monthly outgoings while preserving capital for business and investment opportunities.

Market Insight Surrey Demand

Prime locations such as Weybridge and Walton-on-Thames continue to attract strong demand due to their connectivity to London, riverside settings, and high quality housing stock.

At the same time, demand for country homes remains robust as buyers place greater emphasis on space, privacy, and lifestyle balance.

Summary

This case study demonstrates how a £4.5 million private bank mortgage can unlock a dual property strategy, combining a prime Surrey residence with a country home while maintaining financial flexibility.
