Large mortgages of £1m+ — illustrative scenarios

6 illustrative situations for large mortgages of £1m+, with preparation questions and considerations. These are not actual client cases or promised outcomes.

Illustrative scenarios, not client case studies.

These examples explain situations worth discussing. They are not records of actual clients, approvals, quotations or completed transactions. Any outcome would depend on an individual assessment.

Illustrative scenario 01

A substantial London purchase

A buyer needs a larger loan and has several income streams. Evidence and total exposure need a coordinated review.

Useful information for the conversation

  • Requested loan and purchase price
  • Detailed income evidence

The aim is to identify the questions and evidence that matter before making a commitment. A short outline is enough to begin; detailed records can follow through an agreed secure route.

Illustrative scenario 02

A larger remortgage

A homeowner wants to refinance a significant balance. Fees, valuation and exit costs deserve comparison over the same period.

Useful information for the conversation

  • Detailed income evidence
  • Asset and liability schedule

The aim is to identify the questions and evidence that matter before making a commitment. A short outline is enough to begin; detailed records can follow through an agreed secure route.

Illustrative scenario 03

A part interest-only proposal

A borrower proposes different repayment methods across the loan. The capital repayment strategy must be credible and evidenced.

Useful information for the conversation

  • Asset and liability schedule
  • Source of deposit and cash reserves

The aim is to identify the questions and evidence that matter before making a commitment. A short outline is enough to begin; detailed records can follow through an agreed secure route.

Illustrative scenario 04

Evidence focus: Make the size and structure work together

A mortgage applicant is considering large mortgages of £1m+. The brief includes requested loan and purchase price and a separate question about detailed income evidence. The maximum loan for a product may be lower than the lender's general lending capacity. The evidence and the decision need to be considered together rather than in isolation.

Useful information for the conversation

  • Source of deposit and cash reserves
  • Floor plans, acreage and any separate buildings or titles

The aim is to identify the questions and evidence that matter before making a commitment. A short outline is enough to begin; detailed records can follow through an agreed secure route.

Illustrative scenario 05

Decision point: Asset and liability schedule

A mortgage applicant is preparing for large mortgages of £1m+, but the information about asset and liability schedule changes while a question about source of deposit and cash reserves remains unresolved. The earlier outline is updated, the original focus is reconsidered and the next step is agreed using the current facts.

Useful information for the conversation

  • Floor plans, acreage and any separate buildings or titles
  • Current property use, intended works and planning information

The aim is to identify the questions and evidence that matter before making a commitment. A short outline is enough to begin; detailed records can follow through an agreed secure route.

Illustrative scenario 06

A £1m+ loan for a home with an annexe and substantial grounds

A family wants a larger home with an annexe, several acres and an outbuilding used by a small business. The borrowing requirement exceeds £1m. The asking price alone does not explain the property to a prospective lender.

A closer look

What makes this different?

The property’s title, use and marketability need as much attention as the applicants’ income. An annexe or business use cannot simply be treated as an ordinary extra room.

How I would work through it

  1. Separate the main residence, annexe, land and outbuildings on a plan, identifying occupiers and any commercial activity.
  2. Check the title structure, planning position and intended future use with the appointed legal advisers.
  3. Present the borrowing amount, affordability evidence and property brief together before relying on a particular lender route.

Evidence to bring together

  • Floor plans, site plan and acreage
  • Title information, occupancy and current use of each building
  • Income, liabilities, deposit source and the proposed loan

The decision to reach

A suitable route depends on the specific property and borrower assessment. If a building has separate use or a material issue remains unresolved, the finance structure and timing may need to change.

The wider assessment

Make the size and structure work together

The maximum loan for a product may be lower than the lender's general lending capacity. Property valuation, income concentration and liquidity can receive closer scrutiny. We compare a single facility with any proposed split before considering the practical costs.

A larger deposit does not guarantee a particular loan size. Underwriting and valuation remain case-specific.
