If you’ve accumulated enough savings to cover 90% of a property’s purchase price, you’d only need to borrow the remaining 10%—sometimes called a 10% mortgage. This arrangement can unlock the possibility of lower interest rates, more manageable monthly payments, and a healthy cushion if house prices shift.
Below, The Mortgage Pod explains how a 90% deposit (10% mortgage) works, who might benefit from it, and which steps you can take to secure one. Let’s get started!
Understanding 90% Deposit Mortgages
A 90% deposit mortgage means you’re contributing 90% of the property’s value in cash, leaving the lender to cover the final 10%. For example, if a home costs £300,000, placing a £270,000 deposit means you only need a £30,000 mortgage.
With an LTV (loan-to-value) of 10%, lenders perceive you as a very low-risk borrower. This often translates to competitive interest rates, easier approval checks, and a wide range of product options—more than you’d typically see if you needed a higher LTV mortgage.
Understanding Mortgage Deposits
When buying a property, the deposit is the portion you contribute from your own funds, separate from the amount you borrow. The bigger your deposit, the less you’ll need to take out as a mortgage—which usually means lower interest costs over the life of the loan. A large deposit also tells lenders you’re serious about making repayments, potentially earning you better loan terms.
Minimum Deposit Requirements
Standard mortgages in the UK often start around 5% deposit. Opting for a 90% deposit can yield several advantages:
- Lower risk to the lender, often resulting in more attractive interest rates
- Reduced monthly payments, thanks to borrowing a small proportion of the home’s price
- Greater sense of financial security, given your large initial investment
For Example:
- 90% Deposit on a £250,000 Property = £225,000
- 20% Deposit = £50,000
- 5% Deposit = £12,500
Why Do I Need a Mortgage Deposit?
Deposits fulfil two main purposes:
- They minimise how much you borrow, which typically reduces overall interest paid across the loan term.
- They reassure lenders, showing that you have a significant financial stake in the purchase and are less likely to default.
Factors Affecting Deposit Size
Your deposit amount will hinge on a few considerations:
- Property Type: Some lenders request larger deposits for new-build homes or atypical properties.
- Financial Circumstances: A strong credit profile and steady earnings can make it easier to gather and justify a large deposit.
- Provider Policies: Each mortgage lender has its own rules around deposits and eligibility criteria.
How Do 90% Deposit Mortgages Work?
Aside from the significant deposit, a 90% deposit mortgage operates similarly to other home loans: you repay the borrowed 10%, plus interest, over an agreed term (often 25–35 years). However, because of the low LTV:
- Interest rates can be especially competitive.
- Affordability checks may be less strict compared to smaller deposits, as you’re borrowing so little.
Scenario: If your property is £400,000, placing £360,000 (90%) upfront means only £40,000 needs to be borrowed. This can result in notably smaller monthly outgoings.
Eligibility Criteria for a 90% Deposit Mortgage
Even though your deposit is large, lenders still conduct thorough assessments. They typically look for:
- Favourable Credit History: Evidence of responsible credit usage and on-time repayments.
- Stable Employment or Self-Employment: Payslips or accounts demonstrating consistent income.
- Debt-to-Income Ratio: Fewer existing debts can raise the amount you can borrow.
- Property Constraints: Some lenders won’t finance certain property types, even at low LTVs.
Application Process for a 90% Deposit Mortgage
While each lender has unique steps, the overall path usually involves:
- Review Your Credit Score: Rectify mistakes, clear high balances, and maintain punctual bill payments.
- Compile Documents: Bank statements, proof of income, ID, and address verification.
- Compare Lenders: Rates, fees, and product features vary, so shopping around or speaking to a broker is wise.
- Submit Application: Provide all requested information for affordability checks.
- Mortgage Offer: If approved, you’ll receive a formal offer detailing rates, fees, and conditions.
By teaming up with a mortgage broker—like The Mortgage Pod—you can streamline this process, identify suitable deals, and boost your likelihood of a successful application.
Pros of a 90% Deposit Mortgage
- Potentially Lower Interest Rates: Borrowing just 10% often attracts favourable rates.
- Reduced Monthly Bills: Owing a small loan means more budgetary freedom.
- Greater Equity Position: You begin homeownership with substantial equity if property values stay stable or rise.
- Lower Negative Equity Risk: Should house prices dip, you’re less likely to owe more than the property’s worth.
Cons of a 90% Deposit Mortgage
- Significant Lump-Sum Requirement: Amassing 90% can be a tall order, especially in high-cost areas.
- Opportunity Cost: Tying up a large amount in property can limit your liquidity or investment in other areas.
- Still Subject to Market Shifts: While you’re safer than most, a dramatic price drop can still affect your equity.
- Lender Checks Still Apply: Even with a massive deposit, you must pass credit and income assessments.
Who Can Benefit from a 90% Deposit Mortgage?
- Homeowners Downsizing: Selling an existing property with considerable equity can free up enough for a 90% deposit on a smaller home.
- Long-Term Savers: If you’ve diligently set aside funds or received a significant windfall, a 10% mortgage can be a strong option.
- Buy-to-Let Investors: Although buy-to-let criteria differ, a large deposit can enhance rental returns and simplify approvals.
Are There Any Government Schemes to Assist?
Government help typically targets those with small deposits (e.g., 5%). If you’re going for 90%, it’s unlikely you’ll need official schemes. However, first-time buyers might still be eligible for Stamp Duty relief if the property meets price thresholds.
Additional Costs to Consider
When purchasing a home, remember the deposit isn’t your only outlay:
- Legal & Conveyancing Fees: Covering property searches, contract work, and more.
- Stamp Duty Land Tax: Charged according to property price and buyer status.
- Valuations & Surveys: You might want a thorough survey beyond the lender’s basic valuation.
- Moving Expenses: Removal services, new furniture, and any urgent repairs can add up.
How to Improve Your Chances of Getting a 90% Deposit Mortgage
- Enhance Your Credit Score: Clear outstanding debts, maintain on-time payments, and address errors on your report.
- Prove Stable Earnings: Provide consistent payslips or, if self-employed, thorough accounts for at least two years.
- Lower Your Outgoings: Minimising other financial commitments boosts affordability in the lender’s eyes.
- Demonstrate Extra Savings: Showing you can cover fees and have an emergency fund reassures lenders of your financial stability.
Exploring Lender Options
With a 90% deposit, you’ll probably find numerous providers eager to accept your application. Focus on:
- Interest & Fees: Keep in mind that a deal with a low rate might include heftier arrangement charges.
- Flexibility: Some lenders allow payment holidays or extra overpayments.
- Reputation: Read reviews or get recommendations to gauge how each lender supports customers.
Additional Considerations
- Deposit on Exchange: Typically, 5–10% of the property’s price is due at exchange. Make sure some of your deposit is readily accessible.
- Property Market Fluctuations: You’re in a strong position if prices decline, but no deposit eliminates market risk fully.
- Rent vs. Buy: If you’re short of 90%, you might wait longer to save further or explore mortgages at a lower deposit level.
- Upfront Mortgage Fees: Some products impose booking or arrangement fees—factor these into your overall budget.
Comparing 90% Deposit Mortgages
When assessing potential offers:
- Fixed vs. Variable: Fixed rates remain constant, while variable rates might start lower but can rise with the market.
- Product & Early Repayment Charges: Look beyond the headline rate for any added costs.
- Mortgage Term: Extending your term lowers monthly bills but heightens total interest over time.
Saving for a Mortgage Deposit
If you’re still accumulating the final part of your 90%:
- Set Monthly Goals: Work out how much you need to save each month to hit your target.
- Trim Spending: A detailed budget could spotlight unnecessary outgoings you can reduce.
- Use Savings Accounts & ISAs: Some accounts offer interest or bonuses for consistent savers.
- Boost Income: Overtime, a side gig, or freelance work might speed up your deposit-building process.
Mortgage Deposit and Monthly Payments
How much you place down directly affects your repayments:
- Larger Deposit = Less Borrowing: Typically resulting in smaller monthly costs and improved rates.
- Smaller Deposit = Higher Borrowing: Means pricier monthly bills and bigger interest payments overall.
- Interest Rate Movements: Even slight changes in rates can significantly influence total costs across a 25–35-year term.
How Your Deposit Affects Your Monthly Outgoings
- Mortgage Calculators: Plug in different scenarios to see how deposit changes affect monthly bills.
- Broker Guidance: A mortgage adviser can highlight how a bit more deposit might yield meaningful interest savings.
- Long-Term View: Over decades, even modest rate variations can lead to thousands saved or spent.
Alternatives to Saving a Large Deposit
If 90% sounds tough:
- Lower Deposit Mortgages: Most lenders offer products at 5–20% deposit, though monthly outgoings might be higher.
- Shared Ownership: Buy a share of the home and pay rent on the remainder.
- Family-Supported Mortgages: Guarantor or offset arrangements might reduce your deposit needs.
Options if You Cannot Manage a 90% Deposit
- Extended Mortgage Terms: Spreading repayments can cut monthly costs but raises total interest.
- Guarantor Solutions: A family member’s financial backing may help if you have good credit but lack deposit funds.
- Broker Expertise: Professional advice can reveal niche deals or lesser-known programmes that align with your finances.

Frequently Asked Questions
Can I get a 90% deposit mortgage if I’m self-employed?
Yes, assuming you can provide solid evidence of steady earnings (often two years’ accounts) and maintain a decent credit record. A large deposit helps but doesn’t automatically bypass all lender checks.
Are 90% deposit mortgages only for current homeowners?
No. First-time buyers who’ve saved substantially or received gifts/inheritance can also secure a 10% mortgage—lenders still evaluate credit and affordability as usual.
What if property prices slip?
Having a big equity stake (90%) offers a strong buffer, though a severe dip in house prices can still impact your equity. Nonetheless, you’re far less exposed to negative equity than those at high LTVs.
Can I switch to an even lower LTV mortgage later on?
Absolutely. If your home’s value climbs or you make extra repayments, you might remortgage at an even lower LTV, potentially unlocking superior interest rates.
