10 First-Time Buyer Mistakes in the UK (Avoid These)
Avoid costly mistakes when buying your first home in the UK. Learn the top 10 pitfalls first-time buyers make — updated for 2025.
Introduction: Buying Your First Home in the UK? Don’t Make These Mistakes
Becoming a homeowner is an exciting milestone—but it’s also a complex and high-stakes process. For first-time buyers in the UK the journey from saving a deposit to completing a purchase is filled with decisions that can impact your finances and lifestyle for years to come.
Without proper guidance it’s easy to make mistakes—some of which can cost you thousands of pounds or delay your homeownership goals altogether.
In this guide we’ll walk you through the top 10 most common mistakes to avoid when buying your first home in the UK based on expert insight and real buyer experiences.

1. Not Getting a Mortgage in Principle First
Why It’s a Mistake :
House hunting before knowing how much you can borrow is like shopping without a budget. Sellers and estate agents may not take your offer seriously without a mortgage agreement in principle (AIP) .
What to Do Instead :
Apply for an AIP with a reputable lender or broker before viewing properties
Use it to guide your budget and speed up the offer process
Check your credit score and eligibility before applying

2. Underestimating the Total Costs of Buying
Why It’s a Mistake :
Many first-time buyers focus only on the deposit—but that’s just the beginning. Buying a home involves legal fees stamp duty (if applicable) surveys removals insurance and more .
Typical Upfront Costs Include :
Deposit (usually 5–15% of purchase price)
Mortgage arrangement & valuation fees
Conveyancing (legal) fees
Stamp duty (0% up to £425 000 for FTBs in England/Northern Ireland)
Survey costs
Moving expenses & furnishings
What to Do Instead :
Budget for an additional £3 000–£10 000 on top of your deposit
Use a home-buying cost calculator to estimate everything upfront
3. Ignoring Government Support Schemes
Why It’s a Mistake :
There are several first-time buyer schemes that can significantly reduce the cost of buying a home—but many buyers don’t take advantage.
Support Options Include :
First Homes Scheme (30–50% discount on new-builds)
Shared Ownership (buy part rent the rest)
Lifetime ISA (25% savings bonus)
95% Mortgage Guarantee Scheme
What to Do Instead :
Check eligibility for UK-wide and regional schemes
Open a Lifetime ISA early if you’re under 40
Consider shared ownership if full ownership is out of reach

4. Choosing the Wrong Mortgage Term
Why It’s a Mistake :
A longer term lowers monthly payments—but costs significantly more in interest over time. Many buyers blindly choose 35–40-year terms without thinking long-term.
What to Do Instead :
Compare 25 vs 35-year terms using a mortgage calculator
Choose the shortest term you can comfortably afford
Consider future overpayment options to reduce the total cost

5. Skipping the Survey or Relying Only on a Basic Valuation
Why It’s a Mistake :
Lenders conduct a valuation survey to protect themselves—not you. If you skip a proper survey you risk missing serious issues like subsidence damp faulty wiring or roofing problems .
What to Do Instead :
Choose at least a HomeBuyer Report or a Full Building Survey if the property is older or in poor condition
Read the report carefully and don’t ignore red flags
Use findings to renegotiate or walk away if needed
6. Letting Emotions Override Logic
Why It’s a Mistake :
Falling in love with a property can blind you to its flaws—or push you to overbid especially in a competitive market.
What to Do Instead :
Stick to your budget
View the property with a critical eye (or bring someone objective)
Ask tough questions about condition history and location
7. Overstretching Your Budget to Buy “More”
Why It’s a Mistake :
It’s tempting to borrow the maximum amount offered by your lender but this can leave you “house poor” and vulnerable to interest rate rises or unexpected costs.
What to Do Instead :
Plan your monthly budget including council tax utilities and maintenance
Leave breathing room for lifestyle expenses and emergencies
Remember: Just because you can borrow it doesn’t mean you should

8. Not Researching the Local Area
Why It’s a Mistake :
You’re not just buying a home—you’re buying into a neighbourhood. Poor transport links noise safety issues or lack of amenities can impact your quality of life and resale value.
What to Do Instead :
Visit the area at different times of day
Research local crime stats schools and planning applications
Check commute times and access to services

9. Rushing the Legal and Conveyancing Process
Why It’s a Mistake :
Conveyancing is the legal backbone of your purchase. Rushing or choosing the cheapest solicitor can lead to delays missed issues or bad communication.
What to Do Instead :
Choose a solicitor with solid reviews and good communication
Ask for clear timelines and updates
Read the property information form searches and contract pack thoroughly
10. Not Thinking About Resale or Long-Term Plans
Why It’s a Mistake :
Your first home may not be your forever home. If you don’t consider future resale value lease terms or potential for improvement you might limit your financial options later .
What to Do Instead :
Consider resale appeal (layout garden parking location)
Avoid properties with short leases or hidden maintenance fees
Think 5–10 years ahead: career plans family moving goals

Do I need a Mortgage in Principle before house hunting?
Yes. Getting a Mortgage in Principle helps you understand your borrowing limit, makes sellers take your offers seriously, and speeds up your purchasing process.

What extra costs should I budget for besides the deposit?
Beyond your deposit, you should budget £3,000–£10,000 for legal fees, mortgage valuation, stamp duty (if applicable), surveys, removals, insurance, and furnishing.
