Buying a house is exciting, but if you’re wondering how much house can I afford? You’re not alone.
Let me show you exactly how to figure it out without all the confusing jargon.
Whether you’re a first-time buyer in Manchester, moving to a bigger place in Bristol, or downsizing in Surrey, understanding your buying power is the first crucial step.
Now, let’s dive into it properly, shall we?
Why You Must Know Exactly How Much House You Can Afford
Imagine house-hunting for months… only to realise your dream home is way out of your budget. Painful, right?
That’s why knowing your affordability upfront saves you stress, time, and disappointment.
In simple terms, your affordability depends on:
- How much money do you earn
- Your monthly expenses and debts
- The deposit you have saved
- The mortgage deals you qualify for
- Other hidden costs of buying
Now, let me tell you about the real numbers you should be looking at.
What Lenders Look At When You Apply for a Mortgage
When you walk into a bank or speak to a broker, they won’t just ask, “How much do you earn?”
They’ll dig a little deeper.
Here’s what matters most:
- Income: Salary, bonuses, self-employed earnings
- Debt: Credit cards, car loans, personal loans
- Monthly Expenses: Utilities, childcare, subscriptions
- Deposit: Bigger deposits = better rates
- Credit Score: Shows how reliable you are with repayments
In the UK, most lenders will offer you 4 to 4.5 times your annual income. Some, in special cases, can stretch up to 5.5 times.
Let me give you an example:
Example:
If you earn £30,000 per year, a lender might offer you around £120,000 to £135,000 mortgage.
If you’re buying with a partner, and you both earn £30,000, you could afford between £240,000 to £270,000.
Pretty straightforward, right?
How Your Deposit Size Affects How Much House You Can Afford
Now, let’s talk deposits.
The bigger your deposit, the more house you can afford — and the less you’ll pay monthly.
In the UK, you generally need at least 5% of the home’s price. But 10%-20% gives you access to better mortgage rates.
Real-World Example:
- 5% deposit on a £250,000 home = £12,500
- 10% deposit = £25,000
- 20% deposit = £50,000
Pro Tip: If you can save a 15%-20% deposit, you’ll get much better interest rates, meaning cheaper monthly payments.
How to Calculate “How Much House Can I Afford” — Step-by-Step
Let me show you a super simple way to work it out:
Step 1: Add up your total yearly income.
Include salary, freelance work, bonuses, rental income, etc.
Step 2: Multiply it by 4 or 4.5.
Some lenders may offer up to 5x, but don’t bank on it.
Step 3: Add your deposit amount.
This gives you the total house price you can aim for.
Step 4: Check if the monthly repayments fit into your budget.
Use a mortgage calculator.
Hidden Costs You MUST Plan For (Most Buyers Forget These!)
Now, let me tell you about a few sneaky costs most buyers ignore:
- Stamp Duty: You’ll pay tax if your house costs more than £250,000.
(First-time buyers get discounts)
- Solicitor Fees: Around £1,000 – £1,500.
- Mortgage Broker Fees: Some brokers charge around £500.
- Survey Fees: Expect £300–£1,500 depending on survey type.
- Moving Costs: Hiring a removal company might cost £500–£1,000.
Example:
If you’re buying a £300,000 house, budget an extra £8,000–£10,000 for all extra costs.
Real-World UK Examples: How Much House Different People Can Afford
Let’s make this even more real.
| Buyer Profile | Annual Salary | Deposit Saved | Mortgage Multiplier | Estimated House Price |
| Single Professional in Leeds | £35,000 | £20,000 | 4.5x (£157,500) | £177,500 |
| A couple in Birmingham | £60,000 (combined) | £30,000 | 4.5x (£270,000) | £300,000 |
| Self-Employed Londoner | £50,000 | £50,000 | 4x (£200,000) | £250,000 |
(These are rough estimates, of course. Always double-check with a mortgage advisor!)
Key Factors That Influence the Answer to How Much House Can I Afford?
Buying isn’t just about salary and deposit.
Other things can boost or bust your affordability, like:
- Interest rates: Higher rates mean lower mortgage affordability.
- Debts: Having lots of personal loans or car finance lowers your borrowing power.
- Government Schemes: Shared Ownership or Help to Buy can boost your options.
- Job Type: Stable, long-term employment gets you better deals.
Quick Tip: If you’re self-employed, lenders usually want to see at least 2 years of tax returns.
Should You Stretch Your Budget to the Max?
Short answer: No.
Long answer: Let me explain.
Just because a bank says you can borrow £300,000 doesn’t mean you should.
Think about:
- Future expenses (kids, maternity leave, job changes)
- Emergency funds
- Interest rate rises
Example:
Imagine getting a £1,200/month mortgage when you can comfortably afford £900/month.
That extra £300 might squeeze your lifestyle tighter than you’d like.
Tips to Increase How Much House You Can Afford
Want to boost your buying power? Here’s how:
- Save a bigger deposit.
- Reduce existing debts. (Clear credit cards or loans.)
- Improve your credit score. (Use a tool like Experian UK.)
- Consider longer mortgage terms. (35-year term = lower monthly payments, but you pay more interest over time.)
- Use a mortgage broker. They find better deals that you might miss yourself.
