Buying your first home is one of the biggest financial steps you can take. For many first-time buyer applicants, raising the first-time buyer’s deposit is a key hurdle. Lenders not only want to know how much deposit you have saved up, but also where it came from and whether it is acceptable under their rules.
This blog explains how lenders check deposit sources, including how gifted deposits work, and what you need to prepare when applying for a first time home buyer mortgage in the UK.
What Is a First Time Buyer Deposit?
A first-time buyer deposit is simply the money you put down upfront when buying your first home. It’s your own contribution, with the rest usually covered by a mortgage.
As a general rule, the more you can put down, the more mortgage options you’re likely to have. Most UK lenders ask for a deposit of around 5% to 10% of the property price, although some may want more and some now offer no deposit mortgage options.
Saving that kind of money isn’t always easy for homebuyers – especially the first time around. That’s why many buyers get a helping hand from parents or family members. This is very common – but it does mean the lender will want to know exactly where the money came from and how it was built up.
Why Lenders Need to Check Your Deposit
When you apply for a mortgage, mortgage lenders UK have to check that your deposit money is genuine and legitimate. This isn’t about distrusting you – it’s a legal requirement under UK anti-money-laundering regulations.
They also need to make sure your deposit isn’t actually a loan that you’ll have to pay back later. If it were, that extra repayment could put pressure on your finances and affect whether the mortgage is affordable.
In most cases, lenders will ask for evidence showing:
- How much money makes up your deposit
- Where that money came from
- Whether any of it was gifted or borrowed
This step is usually called source of funds checks. It can feel a bit personal, but it’s a normal part of the process for first-time buyers and nothing to worry about if your paperwork is in order.
Acceptable Sources of Deposit
When preparing your application, common acceptable sources for your first time buyer deposit include:
1. Your savings
Money you have saved in your bank account, or other savings is usually straightforward to prove.
2. Gifted deposits from family
Many first-time buyers use a gifted deposit from parents or relatives to increase their deposit. It is very common in the UK housing market.
3. Sale of assets
If you have sold assets like shares or another property, lenders will want documentation to prove where the money came from.
4. Help-to-Buy or similar schemes
Government-backed schemes can include contributions that count toward your deposit, but you need written proof.
Each lender may have slightly different criteria on who can give a gifted deposit and what proof they need. For this reason, speaking early to a mortgage broker in the UK can help you understand which options match your situation.
What Is a Gifted Deposit?
A gifted deposit is when someone gives you money to help pay your deposit without expecting repayment. It must be a true gift and not a loan. If it looks like a loan, lenders may treat it as additional debt, which may reduce the amount you can borrow.
Rules for Gifted Deposits
A typical gifted deposit must:
- Be a genuine gift with no requirement to repay
- Do not give the donor any claim on your property
- Be declared to your lender and solicitor
- Be backed up with a formal gifted deposit letter from the donor
This letter usually states that the money is a gift, names both you and the donor, and confirms there is no interest or repayment expected.
Who Can Give a Gifted Deposit?
Most lenders accept gifted deposits from close family members such as parents, grandparents, and siblings. Some may also accept gifts from other relatives, but this is up to the individual lender’s rules.
Before accepting the funds, UK mortgage lenders will check that the gift is genuine and not subject to conditions that would affect your mortgage. This includes checking that the deposit funds came from a legitimate, traceable source such as savings or the sale of property.
How Lenders Verify Deposit Sources
Lenders will ask you to show documentation that proves your first buyer deposit is valid. Typical checks include:
- Bank statements: To show how long the funds have been in your account and where they came from
- Gift letters: To confirm that a gifted deposit is non-repayable
- Proof of identity for donors: They may need ID and proof of address
- Source of funds verification: Especially if the money came from the sale of assets or inheritance

Frequently Asked Questions
How long do deposit funds need to be in my account before applying?
There is no fixed time period across all mortgage lenders UK. Some lenders are comfortable if funds have been in your account for a few weeks, while others prefer to see a longer savings history, often three to six months. What matters most is being able to clearly evidence where the money originated and that it is not borrowed.
Can a first-time buyer use multiple deposit sources?
Yes. Many first time buyers combine savings, gifted funds, and proceeds from asset sales. However, every source must be fully declared and documented. Lenders will assess each component separately and may apply stricter checks where deposits come from multiple contributors.
Are cash gifts acceptable as a deposit?
Not usually. Cash gifts are generally discouraged and often declined unless there is a clear audit trail. Mortgage lenders UK usually require gifted deposits to be transferred electronically from the donor’s bank account, with statements showing how the donor accumulated the funds.
Will lenders accept a gifted deposit if the donor lives overseas?
Some lenders will accept overseas gifted deposits, but additional checks are likely. This can include certified translations, foreign bank statements, and enhanced source-of-funds verification. Best mortgage brokers can identify lenders more comfortable with international gifts before you apply.
Does a gifted deposit affect first-time buyer mortgage rates?
No. A gifted deposit does not automatically affect your interest rate. What matters is the overall loan-to-value ratio after the deposit is applied. A larger deposit, regardless of source, can often unlock better mortgage deals for first time buyers.
Can the person giving the gifted deposit live in the property?
Usually, no. Most lenders won’t allow the person gifting the deposit to live in the property or keep any legal interest in it. A gifted deposit is meant to be just that – a gift, with no strings attached.
If the person giving you the money plans to live in the property, you must say this from the start. Not doing so can cause problems later on, or even lead to the mortgage being declined.
Be aware that this situation limits the number of lenders available, but some options may still exist with the right advice.
Do mortgage lenders check the donor’s finances?
Yes. Lenders typically carry out basic checks on the donor, including proof of identity and evidence of where their gifted funds came from. This is part of standard anti-money-laundering regulations and does not usually involve a credit check.
When should a first-time buyer speak to a mortgage broker?
Ideally, before moving deposit funds or accepting a gift. A mortgage broker UK can confirm whether your deposit structure aligns with current lender criteria and helps you avoid issues that could delay or derail your mortgage application later.
Conclusion
When you’re buying your first home and seeking a first time buyer mortgage, the deposit isn’t just about how much you have. Lenders care just as much about where it came from.
Whether it’s your own savings or help from family, every lender will check the source of the money and expect it to meet their rules. If that part isn’t right, applications can stall or be rejected – even if everything else looks fine.
Having someone who knows the process helps keep things simple. A mortgage broker UK can explain what different lenders will accept, tell you what evidence you’ll need, and help you get it right before you apply.
Rest assured – using a mortgage broker will result in fewer delays, fewer questions, and less stress when you’re already juggling a lot!
