The size of your deposit affects both eligibility and the mortgage rate you’ll receive.
In the UK, most residential mortgages require a minimum deposit of 5–10% (up to 95% LTV). However, foreign nationals, new builds, and buy-to-let applicants often need larger deposits — typically 20–25%.
Lenders also set limits based on property type: houses are generally preferred, while flats, ex-council homes, or non-standard construction properties may face stricter assessments.
Higher deposits and stable financial profiles usually lead to more competitive rates and faster approvals.
