Scope: UK-wide; lender criteria vary. Use current official guidance and qualified advice for decisions involving finance, tax or legal rights.
What the deposit does
The deposit is the money you put towards buying the property, with the mortgage covering an agreed part of the remainder. Lenders set their own criteria, so do not treat a deposit percentage mentioned in a general article as an assurance that you qualify for a particular loan.
Keep purchase costs outside the calculation
List the cash intended for the deposit separately from professional fees, taxes, moving costs and essential spending after completion. It is possible to reach a savings target for the deposit while still needing money for the rest of the purchase. Use written quotations where available and mark uncertain amounts clearly.
Translate a percentage into pounds
For illustration, a £30,000 contribution to a £300,000 purchase is 10% of that price. A £270,000 loan would represent 90%. These figures explain the arithmetic only; they are not a lender offer or a recommendation about how much to contribute.
Prepare the evidence
Ask your adviser or conveyancer what evidence is needed to show where the money came from. Explain early if part of it will be a gift or comes from another transaction. Do not assume every lender treats the same funding arrangement identically. Keep documents available and share them only through verified professional channels.
Questions before making a commitment
- What funds are genuinely available, and when?
- Which other purchase costs must come from the same savings?
- What documentation will be requested?
- Would a change in purchase price alter the deposit plan?
- What reserve remains after completion?
A useful savings target is connected to a realistic purchase budget, not just a round percentage. Revisit both when your plans or the property price change.
