Deposit: how much, and where it came from
Most lenders want at least 5% to 10% of the purchase price. Below 20% you usually need lenders mortgage insurance, which adds to the cost and can be added to the loan rather than paid upfront. Lenders also look at how long the money has been in your account: savings built over time read as genuine savings, while a recent lump sum, a gift or a bonus often needs written evidence. The deposit is only part of the cash you need, because stamp duty and inspection costs sit on top of it.
