Snapshot: What Counts as a Mortgage Deposit (and What Doesn’t)?

If you’re planning to buy a property, you’ve probably heard a lot about deposits but what actually counts as an acceptable one? It’s a question that often causes confusion, and sometimes frustration, especially when lenders start asking for detailed proof.

Let’s break it down.

Why does your deposit need to be proven?

When you apply for a mortgage, your broker, lender, and solicitor will all want to see exactly where your deposit has come from. This isn’t just red tape - it’s part of strict anti-money laundering rules known as source of funds checks.

In simple terms: if you can’t clearly show where the money came from, your mortgage won’t go through.

Remortgaging vs buying

If you’re remortgaging, things are fairly straightforward. The equity in your home essentially acts as your deposit.

But if you’re buying a property, it’s a different story. You’ll need to provide a clear and traceable history of the funds you’re using.

So, what is an acceptable mortgage deposit?

Here are the most common sources that lenders are happy with for your deposit:

• Savings built up over time from your income (kept in a bank or building society)

• Investment funds, as long as they can be clearly evidenced

• Gifted deposits from family (with confirmation that it’s a gift, not a loan)

• Money released from another property (for example, via remortgaging)

• Builder incentives on new-build homes

• Proceeds from selling assets like property, jewellery, or antiques

  
  

And what’s usually not acceptable?

Some sources will raise red flags with lenders, including:

• Borrowed money or personal loans used as a deposit

• Large cash deposits without a clear trail

• Cryptocurrency-based funds or monies that are derived from dealing in these 

• Any money that can’t be properly verified

  
  

The bottom line

A good rule of thumb is this: if you can’t prove it, you probably can’t use it.

Before you apply, make sure you have a clear paper trail and supporting documents for your deposit. It might feel like extra effort upfront, but it can save you a lot of delays (and stress) later on.

Getting your deposit in order early is one of the simplest ways to keep your home-buying journey running smoothly.
