High Deposit Mortgages: How a Larger Deposit Unlocks Better Rates & More Options

Saving for a deposit is one of the biggest challenges when buying a property, but having a larger deposit can significantly improve your mortgage prospects. High deposit mortgages offer better rates, greater lender choice and increased flexibility, especially if your financial profile is complex or you have historic credit issues.

This guide explains how deposit size affects mortgage eligibility, what counts as a “high deposit,” and how lenders treat applicants with larger upfront contributions. This article provides general information only and does not offer regulated mortgage advice.

What Counts as a High Deposit?

Different lenders have their own definitions, but high deposit mortgages generally refer to deposits of 15% or more.

Typical deposit tiers:

  • 5% deposit (95% LTV) — minimum for most buyers, strict criteria
  • 10% deposit (90% LTV) — improved lender choice
  • 15% deposit (85% LTV) — considered a high deposit by many lenders
  • 20% deposit (80% LTV) — competitive rates and more flexibility
  • 25% deposit (75% LTV) — opens almost all mortgage options
  • 40%+ deposit (60% LTV) — often qualifies for premium rates

The lower the Loan-to-Value (LTV), the less risk you pose to a lender.

Why a High Deposit Improves Mortgage Options

1. Lower Risk for Lenders

A larger deposit:

  • Reduces lender exposure
  • Increases the equity buffer
  • Reduces chances of negative equity

Lower risk usually means lower rates.

2. Better Mortgage Rates

Interest rates typically improve as LTV bands fall.
For example:

  • 95% LTV — highest rates
  • 90% LTV — better
  • 85% LTV — competitive deals
  • 75% LTV — highly competitive
  • 60% LTV — premium rates

Even a small drop (e.g., from 90% to 85% LTV) can meaningfully reduce monthly repayments.

3. Wider Lender Choice

Many lenders restrict products above 85% LTV.
With a higher deposit, you gain access to:

  • More lenders
  • More product types
  • More flexible underwriting
  • Specialist and high-street options

This stronger competition often results in better pricing.

4. Helps Offset Credit Issues

A high deposit is especially helpful if you have:

  • Old defaults
  • CCJs
  • Missed payments
  • High credit utilisation
  • Thin credit history

Lenders may be more open to applicants with mild or moderate past issues when deposit levels reduce risk.

5. Improves Affordability Outcomes

A higher deposit means lower monthly payments.
Lower payments can:

  • Reduce affordability strain
  • Increase your borrowing capacity
  • Make lenders more comfortable with variable income

This is particularly beneficial for:

How Deposit Size Affects Lender Criteria

Below is a general guide showing how deposit levels shape lender expectations:

5% Deposit – Strict Criteria

  • Clean credit preferred
  • Strong stability required
  • High affordability thresholds

10% Deposit – Moderate Flexibility

  • Small, historic adverse credit sometimes acceptable
  • More lenders available

15% Deposit – High Deposit Threshold

  • Opens up competitive high-street lenders
  • Older defaults or CCJs may be acceptable
  • Good for borrowers with limited history

20% Deposit – Strong Position

  • Competitive rates
  • Flexibility with income types
  • Suitable for self-employed or variable-income applicants

25% Deposit – Widest Access

  • Almost all lenders consider
  • Specialist lenders become more competitive
  • Helpful for recent but settled adverse credit

40%+ Deposit – Premium Pricing

  • Best available rates
  • Most lenient criteria
  • Useful for complex applicants

High Deposit Mortgages for Buyers With Credit Issues

A larger deposit can make a big difference if you have past adverse credit.

Defaults or CCJs

Many lenders accept:

  • Defaults older than 2–3 years
  • Settled CCJs over 3 years old
  • Low-value telecoms defaults

Higher deposits allow more leniency, especially with specialist lenders.

Recent Missed Payments

A high deposit can help offset risk if:

  • Issues are isolated
  • Bank statements show stability since
  • Affordability remains strong

Thin Credit Files

If you have limited borrowing history, a deposit of 15–20% can help balance the profile.

High Deposit Mortgages for Self-Employed Applicants

Self-employed buyers often benefit from high deposits because they:

  • Improve affordability
  • Offset irregular income
  • Support manual underwriting
  • Reduce the need for high income multiples

Lenders may require 1–3 years of accounts, depending on the situation.

High Deposit Mortgages for Buy-to-Let

Buy-to-let mortgages normally require 25% deposits, but applicants with higher deposits may obtain:

  • Better interest coverage ratios
  • Lower rental stress test requirements
  • Access to lower-rate lenders

Higher equity generally means stronger investment outcomes.

How to Build a Higher Deposit More Easily

(General Information Only)

1. Use ISAs to maximise tax-free growth

Particularly helpful for first-time buyers.

2. Reduce non-essential spending

Savings accumulate faster with consistent habits.

3. Pay down high-interest debt

Reduces monthly commitments and frees up cash for saving.

4. Consider buying at a discount

Concessionary purchases or family sales reduce required cash deposits.

5. Save windfalls or bonuses

Lenders often accept these as part of the deposit.

Example Buyer Scenarios

Scenario 1: First-time buyer with 15% deposit

Access to competitive rates and more lenders.

Scenario 2: Applicant with old defaults and 20% deposit

Specialist and some mainstream lenders may consider.

Scenario 3: Self-employed buyer with 25% deposit

Better affordability and strong underwriting outcomes.

Scenario 4: Investor with 40% deposit on buy-to-let

Excellent rental affordability and premium products.

Summary

High deposit mortgages offer significant advantages — from better interest rates to more flexible underwriting and wider lender access. Deposit levels of 15%, 20%, 25% and above increasingly improve your mortgage prospects, especially if:

  • Your credit history isn’t perfect
  • You have variable or complex income
  • You want more competitive monthly repayments
  • You hope to access specialist lending options

With the right preparation and deposit strategy, many buyers find they can secure more favourable mortgage terms than expected.
