Deposit Sources Lenders Accept (and Reject)

Where your deposit comes from matters just as much as how much you have. Lenders don't just want to see the money — they want to know its story. This is partly about anti-money laundering (AML) regulations, but it's also about risk. A deposit that's been carefully saved over years tells a very different story to one that appeared overnight.

The Gold Standard: Savings

If your deposit comes from personal savings built up over time, most lenders will accept it with minimal fuss. They'll typically want to see:

• Bank statements showing the gradual accumulation (usually 3-6 months)
• Evidence the savings came from legitimate income
• Statements from the account where the deposit is held

The key word here is gradual. A lump sum appearing in your account two weeks before your application raises questions, even if it's perfectly legitimate.

Gifted Deposits

Gifted deposits from family members are extremely common — particularly from parents helping first-time buyers. Most high street lenders accept these, but they'll need:

• A gifted deposit letter confirming the money is a gift, not a loan
• Confirmation the giver has no interest in the property
• ID and proof of address for the person giving the gift
• Evidence of where the gift money came from (their bank statements)

Most lenders accept gifts from immediate family: parents, grandparents, and siblings. Some extend this to aunts, uncles, and even close friends, but you'll find the pool of willing lenders shrinks. Lenders like Halifax, Nationwide, and Barclays all accept family gifts with proper documentation.

Inheritance

Money inherited from a deceased relative is generally accepted by all mainstream lenders. You'll need:

• A copy of the grant of probate or letters of administration
• Solicitor's letter confirming the inheritance
• Bank statements showing the funds arriving

If the inheritance was recent, this is usually straightforward. If you inherited money years ago and it's been sitting in savings, just make sure you can trace it back.

Sale of Another Property

If your deposit comes from equity in a property you're selling, this is one of the cleanest sources. The solicitor handling your sale will confirm the net proceeds, and lenders are very comfortable with this.

Bonus, Redundancy, or Compensation Payments

Lump sums from your employer — whether bonuses, redundancy payments, or compensation — are generally accepted. You'll need:

• A letter from your employer confirming the payment
• Bank statements showing it arriving
• Your P60 or payslip showing the payment

Sources That Need More Careful Handling

Cryptocurrency

This is where things get interesting. You've sold Bitcoin or Ethereum and want to use the proceeds as a deposit. A growing number of lenders will consider this, but it requires significantly more documentation:

• Full transaction history from the exchange (Coinbase, Binance, etc.)
• Evidence of the original purchase
• Bank statements showing the fiat currency arriving
• Tax returns showing any capital gains declared

Specialist lenders like Kensington and some building societies have been more open to crypto deposits, but expect extra scrutiny. Some mainstream lenders still refuse crypto-sourced deposits entirely.

Gambling Winnings

Legitimate gambling winnings — a big win on the horses, a lottery prize — can be used as a deposit, but lenders are cautious. You'll need:

• A letter from the gambling operator confirming the win
• Your gambling account history
• Bank statements showing the funds

Personal Loans

Using a personal loan as your deposit is almost universally rejected by mainstream lenders. The logic is simple: if you need to borrow your deposit, can you really afford the mortgage? However, some specialist lenders may consider it in specific circumstances, particularly if the loan is already well-established and being repaid comfortably.

Builder's Incentives and Cashback

Some new-build developers offer cashback or deposit contributions. Lenders are aware of these schemes and many accept them, but they'll want to know the exact arrangement. Typically, the incentive can't exceed 5% of the property value without affecting the loan-to-value calculation.

Sources That Are Almost Always Rejected

• Undocumented cash — money that can't be traced to a legitimate source
• Funds from sanctioned countries — due to international sanctions regulations
• Borrowed deposits disguised as gifts — if a lender discovers a "gift" is actually a loan, the application may be declined or even treated as fraud
• Crowdfunded deposits — money pooled from multiple unrelated individuals

The Paper Trail Is Everything

Regardless of the source, the single most important thing is a clear paper trail. Anti-money laundering regulations require lenders to verify where deposit funds originate. This isn't optional — it's the law.

If you're planning to buy in the next 6-12 months, start organising your evidence now:

1. Keep all bank statements showing the deposit building up
2. If receiving a gift, get the gifted deposit letter prepared early
3. If selling assets (crypto, shares, property), keep full transaction records
4. If you've received inheritance, keep all probate documentation

What If Your Source Is Complicated?

If your deposit comes from an unusual source — or a combination of sources — a specialist mortgage broker is invaluable. They know which lenders are flexible about deposit origins and can present your case in the best light. The difference between a declined application and an approved one often comes down to knowing which lender to approach.

Don't assume your deposit source is a problem until you've spoken to someone who understands the full market. Many people with perfectly legitimate deposits get anxious because their situation doesn't fit the "normal" mould. More often than not, there's a lender who'll work with you.
