£180,000 Mortgage: Monthly Repayments & Income Requirements
If you’re thinking about taking out a £180,000 mortgage, you’re probably wondering how much the monthly repayments will be — and whether your income is enough to get approved.
The truth is, mortgage costs depend on a few key things: your interest rate, mortgage term, and deposit size. At Mortgage Bridge, we help people every day figure out what’s realistic, what lenders are looking for, and how to find the best deal based on your situation.
In this guide, we’ll break everything down clearly so you can see what a £180,000 mortgage might cost you and what you’ll need to qualify.
How Much Is a £180,000 Mortgage Per Month?
Your monthly repayments depend on two main factors — your interest rate and your mortgage term (the number of years you’ll take to repay it).
Here’s a quick breakdown to give you an idea of what to expect:
| Interest Rate | 10 Years | 15 Years | 20 Years | 25 Years | 30 Years |
|---|---|---|---|---|---|
| 3% | £1,738 | £1,243 | £999 | £853 | £759 |
| 4% | £1,824 | £1,332 | £1,093 | £950 | £859 |
| 5% | £1,912 | £1,423 | £1,188 | £1,054 | £969 |
| 6% | £2,001 | £1,516 | £1,287 | £1,160 | £1,082 |
As you can see, stretching your mortgage over a longer term brings your monthly payments down — but you’ll pay more interest overall.
For example:
- A £180,000 mortgage at 4% over 25 years costs around £950 per month.
- The same mortgage at 5% over 25 years is about £1,054 per month.
- Over 30 years at 4%, you’d pay roughly £859 per month, but more in total interest.
If you’d like us to calculate your exact payments based on your deposit, term, and rate, we can do that quickly for you.
How Much Income Do I Need for a £180,000 Mortgage?
Most lenders base mortgage affordability on income multiples, typically between 4 and 4.5 times your annual salary. Some go higher (up to 5 or even 5.5 times), depending on your circumstances.
Here’s a rough guide:
| Income Multiple | Required Income |
|---|---|
| 4x | £45,000 |
| 4.5x | £40,000 |
| 5x | £36,000 |
| 5.5x | £32,700 |
So, to borrow £180,000, your household income usually needs to be around £36,000–£45,000 per year, depending on the lender and your financial profile.
If you’re applying jointly, your combined income is used. For example, a couple earning £22,000 and £20,000 each could comfortably afford this amount with most lenders.
How Does Deposit Size Affect a £180,000 Mortgage?
Your deposit influences both your interest rate and your monthly repayment amount.
Here’s what that might look like:
| Deposit | Mortgage Amount | LTV (Loan-to-Value) | Typical Interest Rate |
|---|---|---|---|
| £9,000 (5%) | £171,000 | 95% | Higher (limited choice) |
| £18,000 (10%) | £162,000 | 90% | Moderate (wider choice) |
| £27,000 (15%) | £153,000 | 85% | Lower |
| £45,000 (25%) | £135,000 | 75% | Excellent (best rates) |
The bigger your deposit, the lower your LTV — which makes you less risky to lenders and helps unlock better deals.
At Mortgage Bridge, we always explore what deposit level gives you the best value for money. Sometimes increasing your deposit by even 5% can save thousands in interest over time.
What Type of Mortgage Is Best for a £180,000 Loan?
There’s no one-size-fits-all answer, but here are the most common types we help clients compare:
Fixed-Rate Mortgage
Your payments stay the same for a set period (usually 2, 3, or 5 years). Great for budgeting and peace of mind.
Tracker Mortgage
Moves in line with the Bank of England base rate, meaning your payments can rise or fall depending on interest rate changes.
Variable-Rate Mortgage
The lender sets and adjusts the rate. You might pay more when rates rise, but sometimes less when they fall.
Offset Mortgage
Links your savings account to your mortgage balance. The more savings you hold, the less interest you pay.
We’ll talk through your goals — stability, flexibility, or faster repayment — and match you with a mortgage that fits.
How Long Should I Take a £180,000 Mortgage Over?
The most common term in the UK is 25 years, but lenders offer anything from 5 to 40 years, depending on your age and circumstances.
Shorter terms mean higher monthly payments but less interest overall. Longer terms mean lower monthly payments but higher total costs.
Here’s an example at 4% interest:
- 10 years: £1,824 per month (£38,880 interest total)
- 25 years: £950 per month (£105,000 interest total)
- 35 years: £799 per month (£127,580 interest total)
If you can comfortably afford higher payments, a shorter term saves you a significant amount long-term. We’ll help you find a balance that fits your budget.
Can I Get a £180,000 Mortgage on One Income?
Yes — you can.
Plenty of single applicants successfully secure a £180,000 mortgage, as long as their income and outgoings fit the lender’s affordability model.
For example:
- On a £45,000 salary, you could typically borrow £180,000 at 4x your income.
- With a higher credit score or strong financial profile, some lenders might offer 4.5x or 5x income, reducing the required salary to around £36,000–£40,000.
If you have a few credit commitments (loans, car finance, credit cards), your borrowing limit might reduce slightly — but we can help present your case clearly to maximise what’s possible.
What If I Have Bad Credit? Can I Still Get a £180,000 Mortgage?
Yes — it’s still possible.
Even if you’ve had missed payments, defaults, or CCJs, some specialist lenders will still consider your application, especially if:
- Your credit issues are over a year old
- You have a larger deposit (15–25%)
- You can show consistent income and stable finances
Rates might be higher initially, but you can often remortgage later once your credit improves.
At Mortgage Bridge, we specialise in helping clients with adverse credit or complex circumstances find realistic solutions that work long-term.
Can I Get a £180,000 Mortgage If I’m Self-Employed?
Absolutely — being self-employed doesn’t stop you from getting a mortgage.
You’ll just need to provide extra documentation to show your income stability. Lenders will typically ask for:
- Two or three years of accounts or SA302s and tax year overviews
- Business bank statements
- Possibly a reference from your accountant
If you’ve only been trading for one year, don’t panic — we work with lenders who’ll still consider you if your figures look strong.
We’ll help present your income properly — including dividends, salary, or retained profits — to show your true affordability.
How Do Lenders Assess Affordability for a £180,000 Mortgage?
Beyond income multiples, lenders look at your full financial picture:
- Your monthly spending and commitments
- Credit score and payment history
- Employment type and stability
- Deposit size
- Any dependents (children, family costs)
They’ll also check your debt-to-income ratio to ensure you can comfortably afford repayments even if interest rates rise.
We’ll review everything with you first, so you know exactly what to expect — no surprises later on.
How Much Interest Will I Pay on a £180,000 Mortgage?
The total interest depends on your term and rate. Here’s a quick example:
| Term | Interest Rate | Total Interest Paid | Total Repayment |
|---|---|---|---|
| 10 years | 4% | £38,880 | £218,880 |
| 20 years | 4% | £86,080 | £266,080 |
| 25 years | 4% | £105,000 | £285,000 |
| 30 years | 4% | £129,440 | £309,440 |
You can reduce interest dramatically by making overpayments — even small ones. For instance, paying an extra £100 a month on a 25-year mortgage could save you over £15,000 in interest and cut years off the term.
Most lenders let you overpay up to 10% per year without penalty.
Can I Use a £180,000 Mortgage for a Buy-to-Let Property?
Yes — if you’re buying to rent, lenders will focus on the rental income potential rather than your personal salary.
Most buy-to-let lenders want the rent to cover at least 125–145% of the mortgage payment (based on a notional interest rate, usually around 5.5–6%).
For a £180,000 loan, that means your rental income would need to be roughly £900–£1,000 per month.
We’ll help calculate your expected rental yield and match you with lenders offering competitive rates for your property type.
