An acceptable interest-only repayment strategy is one that is credible, evidenced, and realistically available at the end of the mortgage term. UK lenders must be satisfied that the capital will be repaid, not just the monthly interest. For high net worth mortgages, lenders may be more open to bespoke strategies, but the evidence requirements are often higher.
Common acceptable strategies include:
- Investments: a liquid portfolio with clear statements, ownership, and value history.
- Sale of another property: supported by valuations and evidence of ownership/equity.
- Pension lump sums: supported by projections and age-related policy rules.
- Sale of the mortgaged property:
What lenders typically don’t like is vague planning, uncertain future windfalls, or repayment dependent on events that may not happen. If the strategy is investments, lenders may discount values to allow for volatility. If the strategy is property sale, lenders will consider marketability and whether selling fits your real-life plan.
The best approach is to choose a strategy you genuinely intend to follow, gather evidence early, and select lenders aligned with that strategy. That keeps underwriting clean and reduces last-minute surprises.
