Putting down a significant deposit on a property can open doors to better interest rates, more manageable monthly costs, and a comforting buffer against housing market dips. A 45% deposit mortgage—sometimes known as a 55% mortgage—is particularly appealing for those who have built up ample savings or benefited from substantial equity in a previous home.

At The Mortgage Pod, we aim to simplify the mortgage experience so that you can make informed decisions every step of the way. Below, we’ll discuss how 45% deposit mortgages work, who they might be suitable for, and what you can do to enhance your likelihood of approval.

Understanding 45% Deposit Mortgages

A 45% deposit mortgage means that you, as the buyer, contribute 45% of the property’s overall cost, while the lender provides the remaining 55% in the form of a mortgage loan. For instance, if the place you’re eyeing costs £300,000, you’d put down £135,000, and the mortgage lender would cover £165,000.

Because you’re borrowing a smaller proportion of the home’s value (a 55% Loan-to-Value (LTV)), lenders typically consider you a lower risk and may be more inclined to offer favourable interest rates.

Understanding Mortgage Deposits

A deposit is your initial financial stake in the property purchase. By contributing a higher percentage of the property price, you automatically reduce the amount you need to borrow—and consequently, the interest you might pay over the life of the loan. Large deposits also reassure lenders that you’re a committed borrower who’s less likely to fall behind on repayments.

Minimum Deposit Requirements

While many UK mortgages start from around 5% deposits, higher deposits—like 45%—bring tangible perks:

  • Potentially reduced interest rates
  • Lower monthly payments
  • More lender options
  • A greater cushion against negative equity

For Example:

  • 45% Deposit on a £300,000 Property = £135,000
  • 25% Deposit = £75,000
  • 10% Deposit = £30,000

Why Do I Need a Mortgage Deposit?

A deposit plays two major roles:

  1. Reduces Your Loan: The more you pay upfront, the smaller your mortgage balance—and the less interest you’ll pay over time.
  2. Shows Financial Readiness: A significant deposit demonstrates you’ve been financially disciplined, lowering the risk for lenders.

Factors Affecting Deposit Size

Your deposit size is influenced by several elements:

  • Property Style and Condition: Certain new-builds or older buildings can prompt lenders to request more substantial deposits.
  • Personal Finances: A strong credit profile and stable income can improve your ability to qualify for bigger deposit products.
  • Lender Policies: Banks and building societies differ in their deposit requirements and loan offerings.

How Do 45% Deposit Mortgages Work?

Aside from the bigger deposit portion, 45% deposit mortgages work similarly to any other mortgage. You take out a loan for the remaining 55% and repay it, plus interest, over a predetermined term (often 25–35 years). Because you’re borrowing at a lower LTV, you may:

  • Receive more competitive interest rates than those borrowing 90% or 95% of a property’s value.
  • Have an easier time passing affordability checks compared to those taking out larger loans.

Example: If you purchase a £400,000 home with a 45% deposit of £180,000, you’ll need a mortgage for £220,000. You’d typically enjoy lower monthly bills than someone only putting down 10%.

Eligibility Criteria for a 45% Deposit Mortgage

Even with a bigger deposit, lenders still need assurance that you can meet monthly payments. They’ll scrutinise:

  1. Credit History: Evidence of timely bill payments and minimal debt is a plus.
  2. Employment and Income: If you’re self-employed, lenders generally want at least two years of accounts.
  3. Existing Liabilities: Smaller ongoing debts can boost the mortgage amount you can be offered.
  4. Property Assessment: Lenders often require a valuation to confirm the property’s true worth.

Application Process for a 45% Deposit Mortgage

Though individual lenders have their own practices, these steps are fairly common:

  1. Review Your Credit Rating: Correct any discrepancies and aim to lower outstanding credit balances.
  2. Gather Documentation: Typically includes payslips or accounts (for the self-employed), bank statements, ID, and proof of address.
  3. Research Mortgage Deals: Each provider will have different rates and fees. Compare carefully.
  4. Submit Your Application: Provide all relevant paperwork so the lender can perform its underwriting checks.
  5. Formal Offer: If you pass the checks, you’ll receive a mortgage offer detailing terms and conditions.

Leveraging a mortgage broker—like The Mortgage Pod—can help you locate deals suited to 45% deposits and smooth out the admin process.

Pros of a 45% Deposit Mortgage

  1. Potentially Better Rates: Borrowing only 55% often unlocks more attractive rates.
  2. Lower Monthly Outgoings: A reduced principal can lead to easier-to-manage repayments.
  3. Enhanced Product Variety: Many lenders prioritise borrowers who bring a substantial deposit.
  4. Decreased Negative Equity Risk: If home values fall, you’re less likely to owe more than your property is worth.

Cons of a 45% Deposit Mortgage

  1. High Initial Outlay: Saving or obtaining almost half the property’s cost is challenging.
  2. Reduced Liquidity: Large property deposits can limit your savings buffer or investment options.
  3. Market Fluctuations: While you have more protection than most, property price slumps could still impact your equity.
  4. Usual Lender Checks Still Apply: Meeting deposit requirements doesn’t guarantee approval if you fail affordability or credit checks.

Who Can Benefit from a 45% Deposit Mortgage?

  • Homeowners Trading Up or Down: Proceeds from a previous sale might make hitting 45% feasible.
  • Savers or Gifted Deposits: Anyone who’s saved diligently or received a financial boost (like inheritance) could gain from a 55% mortgage.
  • Buy-to-Let Investors: Larger deposits can enhance rental yield if interest rates are reduced.

Are There Any Government Schemes to Assist?

Schemes like Help to Buy generally target smaller deposits. However, even with a larger deposit, you might still benefit from Stamp Duty relief if you’re a first-time buyer (subject to thresholds). It’s best to speak with an adviser about your specific situation.

Additional Costs to Consider

Remember, the deposit isn’t the only financial commitment:

  1. Conveyancing & Legal Fees: Covering property searches, contracts, and admin.
  2. Stamp Duty: Depending on the purchase price and your status as a buyer.
  3. Survey & Valuation: Basic valuations may be required by lenders, and more detailed surveys can cost extra.
  4. Moving & Setup Costs: Don’t forget removal expenses, furnishings, and any immediate home improvements.

How to Improve Your Chances of Getting a 45% Deposit Mortgage

  • Elevate Your Credit Score: Pay down debts, avoid missed payments, and keep credit utilisation low.
  • Demonstrate Stable Income: Many lenders love to see consistent payslips or at least two years of self-employed accounts.
  • Keep Other Debts to a Minimum: Minimising credit card balances or personal loans can free up borrowing capacity.
  • Prepare for Additional Fees: Proving you have funds for legal costs and an emergency fund showcases strong financial planning.

Exploring Lender Options

Before finalising any decision, explore:

  • Interest Rates & Fees: A seemingly low rate can be overshadowed by high arrangement costs.
  • Product Flexibility: Overpayment facilities or fixed vs. variable rates might be deciding factors.
  • Lender Reputation: Look for reviews or ask for recommendations to understand how supportive the lender is.

Additional Considerations

  • Exchange Deposit: Typically, you’ll pay 5–10% at the exchange of contracts, so ensure a segment of your deposit is immediately accessible.
  • Market Stability: Even 45% doesn’t eliminate risk—property values can fluctuate.
  • Rent vs. Purchase: If you haven’t reached the 45% threshold, you might consider renting a bit longer to save more or explore a smaller deposit route.
  • Mortgage Arrangement Fees: Some mortgage deals charge set-up fees that should be factored into your total outlay.

Comparing 45% Deposit Mortgages

When choosing a mortgage, pay attention to:

  1. Fixed vs. Variable Rates: A fixed rate provides certainty, whereas variable can shift with market movements.
  2. Overall Charges: Consider arrangement fees, valuation costs, and potential early repayment charges.
  3. Loan Term: Longer terms reduce monthly amounts but increase total interest over time.

Saving for a Mortgage Deposit

If you still need to top up your deposit:

  • Set Saving Targets: Determine how much to save monthly to reach your 45% goal.
  • Create a Budget: Track every expense to spot areas where you can cut back.
  • Consider Dedicated Savings Accounts: ISAs or high-yield accounts may accelerate your progress.
  • Seek Extra Income: Overtime, side gigs, or freelance work can further bolster your savings.

Mortgage Deposit and Monthly Payments

Your deposit size directly affects how much you owe every month:

  • Bigger Deposit = Smaller Loan: This often results in lower monthly obligations.
  • Smaller Deposit = Higher Loan: Typically means pricier monthly bills and interest charges.
  • Interest Rate Differences: Even a small shift in interest can mount up over decades.

How Your Deposit Affects Your Monthly Outgoings

  • Use a Mortgage Calculator: Plug in different deposit amounts to see how your payments change.
  • Talk with a Broker: A professional can demonstrate how adding just a bit more to your deposit might yield big interest savings over the term.
  • Plan for the Long Haul: Evaluate the full cost, not just the initial rates.

Alternatives to Saving a Large Deposit

If 45% is out of reach:

  • Lower Deposit Mortgages: You can opt for 5%, 10%, or 20% deposit deals, albeit with higher monthly payments.
  • Shared Ownership: Buy a share of your home and pay rent on the remaining portion.
  • Guarantor or Family-Backed Schemes: This could help you access more competitive products without a massive lump sum.

Options if You Cannot Manage a 45% Deposit

  • Longer Mortgage Terms: Spreading payments over 30–35 years can cut monthly costs, albeit with increased overall interest.
  • Guarantor Loans: Friends or relatives who can vouch for you can lower deposit requirements in some scenarios.
  • Seek Expert Guidance: A broker may reveal products or strategies you hadn’t considered, such as offset mortgages or niche deals.

Conclusion: Is a 45% Deposit Mortgage Right for You?

A 45% deposit mortgage can offer reduced monthly costs and more competitive interest deals, alongside extra safety if the property market wobbles. That said, gathering nearly half of a home’s purchase price is no easy feat. You’ll also need to pass standard affordability checks.

Frequently Asked Questions

Can I get a 45% deposit mortgage if I’m self-employed?

Yes, as long as you can demonstrate steady income streams, typically via at least two years of accounts. A 45% deposit gives lenders extra confidence, but they’ll still check your credit history and affordability thoroughly.

Are 45% deposit mortgages only for seasoned homeowners?

Not necessarily. If first-time buyers have saved or received financial gifts equating to 45% (e.g., from parents), they can also apply—provided other lending criteria are met.

What if the property market goes down?

While a larger deposit provides a more robust equity buffer, a severe fall in prices could still erode your stake. However, you’d still be more protected compared to someone on a higher LTV mortgage.

Can I switch to a lower LTV mortgage further down the line?

Yes. If your property’s value increases or you make overpayments, you can remortgage at a lower LTV, potentially securing even better interest rates.
