Compare First-Time Buyer Mortgages →Can You Afford That Dream Home?
The first, and perhaps most daunting, task? Figuring out exactly how much you can borrow. Take a deep breath and tally up your deposit—typically, you'll need to put down at least 5% of your chosen home's purchase price.
💡 Real Example
For that $280,000 starter home, you're looking at a minimum deposit of $14,000. Upping your deposit to 10% or 15% improves your chances of landing a lower mortgage rate—meaning cheaper monthly payments and less risk of falling into 'negative equity' if the market dips.
Not sure what those numbers mean for your budget? Online mortgage calculators make playing with the figures easier than ever. Adjust your deposit, term, or property value and see your potential repayments change in real time.

The Mortgage Maze: Securing an Agreement in Principle
Before you can claim to be a serious buyer, you'll want a mortgage agreement in principle (AIP). This is a statement from a lender that they're—at least in theory—willing to lend you a certain amount.
✅ AIP Benefits
- Commitment-free initial approval
- Only uses a soft credit check (won't hurt your score)
- Gives estate agents signal you mean business
- Usually lasts 2-3 months
- Renewing is as simple as reapplying

Application Approved? Not So Fast!
Once you have your offer accepted on a property, brace yourself for the formal mortgage application—complete with a full affordability check, a hard credit search, and a forensic examination of your income, spending, and credit history.
📋 What Lenders Check
Income Verification
- Payslips (last 3 months)
- P60 or tax returns
- Bank statements
- Bonus/commission proof
Spending Analysis
- Credit card balances
- Loan commitments
- Regular outgoings
- Lifestyle spending
Don't fret if this takes a few weeks: most final decisions come within two to six weeks, depending on your circumstances and paperwork.
⚠️ Did You Know?
The Financial Conduct Authority's rules mean lenders must check you can handle your payments even if interest rates go up—unless you fix your rate for at least five years.
2025's Rate Reality: Stamp Duty and Mortgage Trends
This year, first-time buyers in England face higher stamp duty thresholds, with those purchasing homes over £300,000 (previously £425,000) now subject to the taxman's demands.
🚨 Stamp Duty Changes 2025
Old threshold: $425,000 (no stamp duty for first-time buyers)
New threshold: $300,000 (effective from April 2025)
This means if you're buying a $350,000 property, you'll now pay stamp duty on $50,000 at 5% = $2,500 extra cost.
On the bright side, mortgage rates have softened in 2025 compared to their highs, with the best rates dipping below 4% as of June—though chunky deposits and solid credit are essential for bagging those bargains.

With dozens of choices, picking the best first-time buyer mortgage can get overwhelming. Let's break them down:
🔒 Fixed-Rate Mortgages
Lock your monthly costs—perfect for budgeting. Your rate stays the same for 2, 3, 5, or even 10 years.
Best for: First-time buyers who want payment certainty and protection from rate rises.
📊 Tracker Mortgages

Your lender's 'default'—usually pricier and more unpredictable. Most borrowers switch away from SVR after their initial deal ends.
Best for: Temporary situations or when planning to remortgage soon.
🎯 Discount Rate Mortgages
Offer a discount on the SVR—savings are possible, but payments can still fluctuate with the lender's SVR changes.
Best for: Buyers wanting lower initial rates but accepting some risk.
🛡️ Capped Mortgages
Add security with an upper limit on how high your payments can climb, while still benefiting if rates fall.
Best for: Buyers wanting flexibility with downside protection.
💰 Offset Mortgages
Let you use your savings to reduce mortgage interest—ideal for those with sizeable nest eggs. Your savings aren't locked away but reduce the balance you pay interest on.
Best for: Buyers with $10,000+ in savings who want tax-efficient interest reduction.

Get Started Now →Frequently Asked Questions
What is the minimum deposit for a first-time buyer in 2025?
The minimum deposit is typically 5% of the property's purchase price. For a $280,000 home, that's $14,000. However, larger deposits (10-20%) unlock better interest rates and lower monthly payments. Some schemes like Shared Ownership allow even smaller deposits on your share of the property.
How much can I borrow as a first-time buyer?
Most lenders offer 4-4.5 times your annual salary. For example, if you earn $40,000, you could borrow $160,000-$180,000. Joint applications combine both incomes. Lenders also check affordability based on your outgoings, debts, and ability to handle rate rises.
What is the stamp duty threshold for first-time buyers in 2025?
As of April 2025, first-time buyers pay no stamp duty on properties up to $300,000 (reduced from $425,000). For properties between $300,000-$500,000, you pay 5% on the amount above $300,000. Properties over $500,000 don't qualify for first-time buyer relief.
Should I choose a fixed or tracker mortgage?
Fixed-rate mortgages offer payment certainty—your rate stays the same for 2-10 years, perfect for budgeting. Tracker mortgages follow the Bank of England base rate, so payments can go up or down. In 2025, with rates potentially falling, trackers might save money, but fixed rates offer security. Most first-time buyers choose 2-5 year fixed deals for stability.
What is a Lifetime ISA and should I use one?
A Lifetime ISA (LISA) is a savings account for under-40s where the government adds 25% to your savings (up to $1,000/year). You can save $4,000 annually and use it for your first home (up to $450,000) or retirement. It's one of the best ways to boost your deposit, but there's a 25% penalty if you withdraw for other purposes.
How long does it take to get a mortgage approved?
An Agreement in Principle (AIP) takes minutes to a few days. The full mortgage application takes 2-6 weeks depending on your circumstances, documentation, and property survey. Complex cases (self-employed, bad credit, leasehold properties) can take longer. Start early and have all documents ready to speed up the process.
Can I get a mortgage with bad credit as a first-time buyer?
Yes, but it's harder and rates will be higher. Specialist lenders work with borrowers who have CCJs, defaults, or missed payments. You'll likely need a larger deposit (15-25%) and face higher interest rates. Improving your credit score before applying—paying off debts, registering to vote, fixing errors—can significantly improve your chances and rates.
What are the best mortgage rates for first-time buyers in 2025?
As of October 2025, the best first-time buyer rates start around 3.9-4.5% for 2-year fixed deals with 15-20% deposits. 5-year fixes range from 4.2-4.8%. Rates vary based on deposit size, credit score, and lender. Compare current rates from 50+ lenders to find the best deal for your situation.
