Securing a Luxury Property with a Large Bridging Loan on Main Residence

The situation

In Q4 2025, a high-net-worth client identified a £4.5 million residence in a prime Home Counties village. Six bedrooms, extensive grounds, comprehensively renovated. The seller required exchange and completion within six weeks. Traditional mortgage options, both private bank and high street, could not move fast enough. We arranged a £4 million regulated bridging loan and completed in under five weeks from first enquiry.

The client was a UK-resident individual in his late 50s. His total asset base was approximately £8 million across property and investments. The issue was not wealth. It was liquidity. His assets were split between a £3 million main residence and a substantial investment portfolio, both of which required time to realise at sensible values. He needed a facility structured around his exit, not the lender's preferred timeline.

Why a standard mortgage was not viable

At the loan size and timeline required, conventional options fell short on both speed and structure. A private bank mortgage for a £4.5 million purchase typically requires 8 to 16 weeks of underwriting. In a tightly held village market, with other buyers interested, a slow approval process meant losing the property entirely.

Beyond speed, the client's income structure did not fit standard affordability models cleanly. His income came from an investment portfolio and a European holiday rental. Bridging lenders underwrite primarily on the exit strategy and the security position rather than income multiples, which made the product a more natural fit.

Regulated bridging on a main residence

Because the new property was to become the client's primary residence, the loan was classified as a regulated bridging loan under the Mortgage Credit Directive. This means the borrower receives the same consumer protections that apply to residential mortgages: documented affordability assessments, formal suitability advice, and specific disclosure requirements. It also carries the same risk, the primary residence is charged as security, and failure to repay puts the home at risk.

For the lender, the client's overall asset and income profile allowed the case to be structured on a high-net-worth basis, which permitted more flexible underwriting within the regulatory framework. This is not standard; it required a lender with specific appetite for large regulated loans and experience in complex exit structures.

How the facility was structured

We sourced competing terms from multiple specialist lenders, negotiating on term length, interest structure, early repayment provisions, and fee flexibility. The final facility was:

The 2-year term was the critical structural decision. Most regulated bridging runs to 12 months. Negotiating a 24-month facility required a lender with the right appetite and a well-evidenced exit plan. The retained interest structure for the first year meant the client had no monthly outgoings on the bridge during the initial period, preserving cash flow while he progressed the sale of his current home and restructured his investment portfolio.

We stress-tested the rolled-up interest position carefully. At the agreed monthly rate over 12 months of retention, plus arrangement and legal fees, the total facility remained comfortably within the sub-65% gross LTV ceiling when modelled against both the new property and the existing home. The lender's exposure was further cushioned by the combined security value of both assets.

What we look for in a case like this is not one exit route but two or three. The lender needs to see that if the primary exit takes longer than expected, alternatives exist. Here, the three credible routes were the existing property sale, investment liquidation, and refinancing onto a private bank mortgage. That combination is what made the extended term achievable.

Timeline: enquiry to completion

The upfront strategy call in week one was essential. Going into that conversation with a complete picture of the client's assets, existing charges, income streams, and preferred exit sequence gave us what we needed to present a clean, credible case to lenders from the start. Cases that arrive at bridging lenders in pieces, with questions that should have been resolved by the broker, slow down or derail. This one did not.

Exit strategy

The agreed exit was staged across 2026 and 2027. The primary route was the sale of the client's existing home, with sale proceeds directed as a capital reduction against the bridge. Any remaining balance would be cleared through investment disposals or refinanced onto a private bank long-term mortgage once the new property's ownership was established and income documentation was in order.

We modelled three scenarios with the lender:

• Base case: Existing home sells in 2026 at current appraisal. Proceeds reduce the bridge to a refinanceable level. Remainder transitions to private bank mortgage.
• Conservative case: Sale takes six months longer. Prices 10% below initial estimates. Investment income covers any interest shortfall. Facility remains within LTV limits throughout.
• Stress case: Market conditions deteriorate. Full refinance of the remaining balance at term end. Still achievable based on the client's overall net worth and the property's intrinsic value.

No ERC structure after month 3 was a specific negotiating point. As units of the existing portfolio sold, the client needed the ability to direct proceeds straight to capital repayment without penalty. This reduces the rolled-up interest burden progressively and improves the loan position ahead of any eventual refinance.

Risk considerations

Using a primary residence as security for a bridging loan carries real risk. If the exit fails and the loan cannot be repaid at term, the lender holds the right to take possession of both secured properties. This is not a structure to use without thorough exit planning and independent legal advice.

For this facility, we addressed risk at each stage: conservative LTV positioning, multiple credible exit routes, independent solicitor advice on the implications of the first charge on the main residence (required for all regulated bridging loans), and early repayment flexibility to reduce the balance as assets were disposed of in sequence. The combined security across two properties, with the existing home unencumbered, gave the lender genuine comfort at every scenario modelled.
