Real estate investment can make you rich, but it often leads to disappointment.
Recent data from The Independent found that nearly 20% of buy-to-let landlords in the UK regret spending too much on home renovations that didn’t increase rental income or property value.
You don’t want to be just another sad story.
We, at Advent Communications, have helped many investors overcome these issues, and now it’s your turn.
This article clearly highlights eight costly mistakes real estate investors make in 2025 and shows how to avoid them.
Costly Property Mistakes Investors Make in 2025
Here are the eight costly property mistakes that investors keep on making in 2025:
-
Overlooking Energy Efficiency Ratings
Energy Performance Certificates (EPC) are important for protecting your investment. If you are buying a property to rent out, the energy efficiency rating is key for attracting tenants, determining property value, and maintaining profits.
A low EPC rating can make your property less appealing to potential tenants. As energy costs rise, people are more likely to choose energy-efficient homes to save on bills. Additionally, properties that do not meet basic energy standards may face penalties or struggle to obtain financing.
During the initial quarter of 2025, the quantity of EPCs submitted for new homes in England and Wales fell by 14%, whereas established homes experienced a 7% rise. In fact, 69% of newly constructed homes were given a B rating, while 86% of established homes earned ratings of C or D.
How to Avoid: Make sure your property has an EPC rating of at least “E” to meet legal requirements. Make energy-saving upgrades, like adding insulation, replacing windows, and updating your heating system. These improvements make your property more and more attractive to renters and may also increase its market value.
-
Ignoring Local Planning Policy Changes
Local planning regulations can change unexpectedly, and failing to keep up with these changes can result in major losses over time.
Changes in local planning rules may limit what you can do with your property. Let’s take an example: a new zoning law might prevent you from expanding your property, or new building rules could delay your project and increase costs.
How to Avoid: Stay informed about local planning updates by regularly checking with your local council or signing up for planning newsletters. Being aware of these changes can help you make more informed investment decisions and avoid unexpected costs.
-
Skipping Asbestos Surveys in Older Buildings
Neglecting to conduct an asbestos survey when purchasing a property before 2000 is a grave mistake. Buildings from this era may still contain asbestos, which can pose health risks and legal issues if not properly managed.
Removing asbestos can be expensive, and failing to follow health and safety regulations can result in hefty penalties and delays. The presence of asbestos can also complicate renovations or insurance coverage.
How to Avoid: Always have an asbestos inspection done before purchasing a property built before this century. If you find asbestos, have it removed by a skilled professional. Properties built before 2000 still carry serious asbestos risks that can delay deals, hike insurance premiums, or trigger regulatory fines. Services like advanceasbestosremoval.co.uk provide licensed surveys and safe removal – making sure your investment stays compliant and future-proof.

Understanding Long-Term Maintenance Costs
Many investors make an error by focusing only on initial costs of buying a property while ignoring ongoing maintenance expenses. If you skip regular maintenance, you could end up with much higher costs later.
Not setting aside money for long-term maintenance can lead to expensive repairs down the line. Minor issues, like a leaking roof or broken heating system, can turn into bigger problems if you don’t fix them quickly.
How to Avoid: Always think about ongoing maintenance costs when looking at your return on investment (ROI). Create a maintenance fund for everyday tasks like plumbing repairs, painting, or replacing appliances. It’s better to be prepared for these costs than to face unexpected expenses that could eat into your profits.
-
Failing to Vet Tenants Properly
Leasing to the wrong tenants can lead to expensive problems, like unpaid rent, property damage, and legal issues. It’s vital to screen tenants carefully to ensure they’re reliable.
If tenants fail to pay rent or damage the property, you may face legal charges, eviction costs, and repair expenditures. In the worst case, you might have a long vacancy while seeking new tenants, which reduces your rental income.
A report from The Negotiator indicates that fraudulent rental applications have risen by 140% in 2024, highlighting the rising necessity for comprehensive tenant screening to safeguard landlords against possible financial setbacks.
How to Avoid: Conduct thorough background checks, like credit histories, references from previous landlords, and employment verification. Write clear rental agreements and payment schedules to avoid conflicts. Also, hire a professional property management firm to handle tenant communications and screenings.
If you are new to buying rental properties, you can check an article that clearly mentions the rental checklist before buying. This checklist will help you remember essential tasks like inspecting for screening tenants.
-
Overpaying for Properties
Falling in love with a new property is simple, but overpaying can hurt your investment. This mistake can happen to both new and experienced investors.
Overpaying for a property means you lose money right away. Emotional attachments to the property or not understanding the market can lead to this mistake, which can lessen your return on investment.
How to Avoid: Always do thorough research before buying a property. Use property assessors and look at recent sales in the area to find a fair market value. Don’t rely on your feelings to decide how much a property is worth.
If you’re looking for a property investment and you want to know about its hidden costs, you are required to know about hidden costs that most of the investors just ignore.
-
Neglecting Tax Implications
Investing in property can have big tax consequences, and many investors do not fully understand the tax rules. This lack of understanding can lead to long-term losses.
Failing to prepare for taxes can result in unexpected costs. You may face capital gains tax when you sell a property or even pay more taxes because of how you structure your investments. Not knowing about property taxes can cut into your profits.
How to Avoid: Get advice from a tax expert who specialises in real estate. They can help you understand how taxes will impact your investment and guide you in organising your investments to minimise taxes. Stay informed about property tax rules, including changes to stamp duty or capital gains tax.
-
Not Having the Right Insurance Coverage
Lacking proper insurance may put you at major financial risk. Real estate investments carry many risks, including unintentional harm and legal conflicts with renters, making it essential to have suitable insurance in place.
Without coverage, you may have to pay for costly repairs, attorney fees, or lost rental income from your own funds. Even minor accidents can escalate into significant financial issues if you lack adequate insurance coverage.
Ensure you possess thorough landlord insurance that includes protection for property damage, lost rent, and tenant liability. If you are investing into commercial real estate, make sure you have protection designed for the unique risks linked to that industry.
Conclusion
Investing in real estate can lead to great profits, but you need to avoid costly mistakes. Forgetting to do necessary inspections or miscalculating ongoing costs can hurt your finances.
Staying informed and proactive helps you protect your investments and increase profits. Remember that smart investors not only avoid mistakes; they learn from them and build better portfolios for the future.
