90% Deposit Mortgages | Home Buying with a 10% mortgage

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:

1. They minimise how much you borrow, which typically reduces overall interest paid across the loan term.
2. 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:

1. Favourable Credit History: Evidence of responsible credit usage and on-time repayments.
2. Stable Employment or Self-Employment: Payslips or accounts demonstrating consistent income.
3. Debt-to-Income Ratio: Fewer existing debts can raise the amount you can borrow.
4. 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:

1. Review Your Credit Score: Rectify mistakes, clear high balances, and maintain punctual bill payments.
2. Compile Documents: Bank statements, proof of income, ID, and address verification.
3. Compare Lenders: Rates, fees, and product features vary, so shopping around or speaking to a broker is wise.
4. Submit Application: Provide all requested information for affordability checks.
5. 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

1. Potentially Lower Interest Rates: Borrowing just 10% often attracts favourable rates.
2. Reduced Monthly Bills: Owing a small loan means more budgetary freedom.
3. Greater Equity Position: You begin homeownership with substantial equity if property values stay stable or rise.
4. 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

1. Significant Lump-Sum Requirement: Amassing 90% can be a tall order, especially in high-cost areas.
2. Opportunity Cost: Tying up a large amount in property can limit your liquidity or investment in other areas.
3. Still Subject to Market Shifts: While you’re safer than most, a dramatic price drop can still affect your equity.
4. 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:

1. Legal & Conveyancing Fees: Covering property searches, contract work, and more.
2. Stamp Duty Land Tax: Charged according to property price and buyer status.
3. Valuations & Surveys: You might want a thorough survey beyond the lender’s basic valuation.
4. 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:

1. Fixed vs. Variable: Fixed rates remain constant, while variable rates might start lower but can rise with the market.
2. Product & Early Repayment Charges: Look beyond the headline rate for any added costs.
3. 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.

Conclusion: Is a 90% Deposit Mortgage Right for You?

A 90% deposit mortgage (borrowing only 10%) can bring a host of benefits—from reduced monthly bills and potentially superb interest rates to a secure foothold should the housing market shift. Of course, accumulating 90% of a home’s cost can be challenging, and typical lender checks on credit and affordability remain.
