If you’re applying for your first mortgage, it’s important to understand how much you can afford, what deposit you’ll need, how lenders assess your income, and what type of mortgage suits you. Getting clear Mortgage Advice in the UK before you apply can help you avoid mistakes and feel more confident about buying your first home.
Buying Your First Home? Start Here
Buying your first home is exciting but it can also feel confusing. You might be wondering:
- How much can I borrow?
- Do I have enough deposit?
- What if my mortgage application gets rejected?
- Which mortgage type should I choose?
These are completely normal questions. That’s why many first-time buyers look for clear first time buyer mortgage advice before applying.
Understanding the basics early can make the whole process smoother and less stressful.
1. How Much Can You Really Afford?
Before viewing properties, you need to know what you can realistically borrow.
Lenders look at:
- Your salary or income
- Monthly spending
- Existing debts
- Credit history
- Future affordability if interest rates rise
Just because a lender offers a certain amount doesn’t always mean it’s comfortable for you long term. Good mortgage affordability advice focuses on what fits your lifestyle not just the maximum number on paper.
2. How Much Deposit Do You Need?
For most first-time buyers in the UK, the minimum deposit is 5% of the property value.
For example:
- 5% deposit = 95% mortgage
- 10% deposit = 90% mortgage
- Larger deposits may give access to better interest rates
When planning your first mortgage UK, make sure you also budget for:
- Solicitor fees
- Surveys
- Mortgage arrangement fees
- Stamp Duty (if applicable)
- Moving costs
3. Understand the Different Types of Mortgages
As a first-time buyer, you’ll likely choose between:
Fixed-Rate Mortgage
Your interest rate stays the same for a set period (usually 2–5 years). This means your monthly payments stay predictable.
Tracker Mortgage
Your rate moves with the Bank of England base rate. Payments can go up or down.
Most first-time buyers prefer fixed rates for stability, but it depends on your comfort with risk and flexibility.
4. Check Your Credit Before Applying
Your credit history plays a big role in whether you’re approved.
Before applying:
- Check your credit report
- Make sure there are no errors
- Avoid taking out new loans or credit cards
- Keep spending steady
Preparation increases your chances of approval.
5. Get an Agreement in Principle
An Agreement in Principle (AIP) confirms how much a lender may be willing to lend you (subject to checks).
- Shows estate agents you’re serious
- Helps narrow your property search
- Gives confidence when making offers
Getting an AIP early makes house hunting more focused.
