Where Can My Mortgage Deposit Come From? A First-Time Buyer Guide (UK)
One common questions first-time buyers ask me is:
“Where can my mortgage deposit actually come from?”
Most people know they need a deposit to buy a home, but many aren’t sure what lenders will accept — or what evidence they may need to provide.
The good news is that deposits can come from several different sources, as long as the lender is able to confirm where the money has come from.
This guide explains the most common deposit sources in the UK and what lenders usually expect to see.

What is a mortgage deposit?
A mortgage deposit is the portion of the property price you pay yourself.
The rest of the purchase price is covered by the mortgage loan.
For example:
• Property price: £200,000
• Deposit: £20,000
• Mortgage: £180,000
The size of your deposit affects something called Loan-to-Value (LTV), which lenders use to assess risk and set mortgage rates.
Generally speaking, the larger your deposit, the lower your loan-to-value and the wider your choice of mortgage deals may be.
Savings
The most common source of a deposit is personal savings.
This could include money saved from:
• Regular monthly savings
• ISA accounts
• Bonuses from work
• Money held in current or savings accounts
Lenders will normally ask for bank statements to show where the savings have built up over time.
This helps confirm where the deposit is coming from.
Gifted deposits
Many first-time buyers receive help from family members in the form of a gifted deposit.
This is when a relative — often parents or grandparents — gives money to help with the purchase of a home.
Most lenders will accept gifted deposits, but they usually require:
• A gifted deposit letter
• Proof of identity from the person gifting the money
• Evidence of where the funds came from
• Confirmation the money is a gift and not a loan
Gifted deposits are one of the most common ways first-time buyers get onto the property ladder.
Inheritance
Money received through inheritance can also be used as a mortgage deposit.
In these situations lenders may ask for documentation confirming:
• The inheritance payment
• Where the funds were held before being transferred
• Proof of the money entering your account
This helps lenders confirm the source of funds.
Equity from another property
Some buyers receive help from family members who release equity from their own property.
For example, parents may remortgage their home to raise funds for a child’s deposit.
As long as the money is gifted and not expected to be repaid, many lenders will accept this as a deposit.
Selling assets
In some cases buyers may use funds from selling assets such as:
• Investments
• Shares
• Premium bonds
• A vehicle or other valuable items
Lenders may ask for evidence showing the sale of the asset and the transfer of funds into your bank account.
Government schemes or specialist products
Some mortgage products allow buyers to purchase with smaller deposits, or even without a traditional deposit.
Examples include:
• £5,000 deposit mortgage products
• Certain 100% mortgage options
• Some schemes designed for renters
Each product has its own criteria and affordability requirements, so eligibility will vary.
Why lenders check deposit sources
Mortgage lenders must confirm where deposit funds come from for several reasons.
These checks help ensure:
• The money is not borrowed in an undisclosed way
• The funds are legitimate
• The buyer can afford the mortgage responsibly
You may therefore be asked to provide bank statements, letters, or documentation showing the source of your deposit.
This is a normal part of the mortgage process.
Final thoughts
Mortgage deposits can come from a range of different sources, including savings, family gifts, inheritance, or the sale of assets.
What matters most to lenders is that the source of funds is clear, traceable, and acceptable under their criteria.
Understanding this early can help first-time buyers prepare their finances and avoid delays during the mortgage application process.
