After 32 years of advising international property investors, certain patterns of error recur with remarkable consistency. The markets change, the specific circumstances differ, but the underlying mistakes are the same — and most are entirely avoidable with the right knowledge and the right team around you.
This guide documents the 20 most common and costly mistakes made by investors buying property abroad. It is not intended to discourage international investment — the opportunities are real and the returns can be excellent — but to help investors avoid the pitfalls that turn promising opportunities into expensive lessons.
Property values can fall as well as rise. This guide is for informational purposes only and does not substitute for independent legal, financial, and tax advice specific to your circumstances.
Mistake 1: Buying on Emotion, Not Analysis
The most common source of poor overseas property decisions is the holiday purchase — falling in love with a location during a break and buying a property driven primarily by personal attachment rather than investment fundamentals.
There is nothing wrong with buying a property you love in a place you enjoy. But the investment case should stand on its own merits. Ask: if I had never visited this location, would these numbers justify this price? If the honest answer is no, you are making a lifestyle purchase, which is a perfectly valid choice — but should be costed and managed as such, not dressed up as an investment.
For a systematic approach to investment selection, see our guide to property investment returns calculations.
Mistake 2: Skipping or Shortcutting Due Diligence
Title disputes, planning violations, undisclosed debts, and structural defects are not rare occurrences in overseas property markets — they are routine. Most are discoverable with proper due diligence. Many investors skip due diligence because it costs money, takes time, or because "the developer is reputable" or "the agent assured me."
The cost of proper due diligence is typically 0.5–2% of the purchase price. The cost of buying a property with a title defect, an illegal extension, or a planning violation can be total loss of the investment.
For a comprehensive checklist, see our guide to property investment due diligence.
Mistake 3: Using the Seller's Lawyer
In many markets, sellers and buyers share the same notary for the transaction. In others, it is common for a single agent to recommend "their" lawyer for all parties. This is a conflict of interest.
Your lawyer acts for you. Their fee is paid by you. Their instructions come from you. A lawyer who also acts for the seller, or whose main client relationship is with the estate agent bringing them transactions, cannot give you independent advice.
Always appoint your own lawyer independently. Ask specifically: "Do you act for any other party in this transaction?" The answer should be no.
Mistake 4: Not Understanding What You Are Actually Buying
In overseas markets, property ownership is not always freehold in the way Western investors expect. In Thailand, foreigners cannot own land outright. In Bali, the nominal ownership structures frequently used by foreigners are legally ambiguous. In many markets, leasehold means very short remaining terms.
Understanding the exact legal interest you are acquiring — freehold, leasehold, right of use, nominee arrangement, company share — and its implications for your rights, your ability to sell, and the eventual return of your capital is fundamental. If your lawyer cannot explain this clearly, find a different lawyer.
See our ownership structure guides for Thailand, Dubai, Greece, Bali, Spain, Egypt, and Cyprus.
Mistake 5: Ignoring the Total Cost of Purchase
The purchase price is only part of what you pay to acquire overseas property. Transaction costs — stamp duty, transfer taxes, notary fees, registration fees, legal fees, agency commissions, currency conversion margins — can add 10–18% of the purchase price in some markets.
A property advertised at €200,000 in Greece can cost €225,000 or more when all transaction costs are included. A property in Spain at €300,000 can require €340,000–€345,000 in total. Not knowing this in advance distorts your return projections and can derail the financial planning for the purchase.
For market-specific buying cost breakdowns, see our guides for UK, Dubai, Greece, Spain, Thailand, Bali, and Egypt.
Mistake 6: Underestimating Ongoing Costs
Overseas properties cost more to run than domestic ones — often significantly more. Management fees, service charges, local taxes, insurance, maintenance, annual permit renewals, tax compliance costs, and the cost of periodic inspection visits all add up.
Investors who model net yields based on gross rent minus only the management fee are typically surprised by how much more the property actually costs to operate. A more realistic model deducts 35–50% of gross rent to arrive at true net income in many markets.
Mistake 7: Trusting Developer Yield Projections
Developers and off-plan marketers routinely publish yield projections. These are not independent analysis — they are marketing materials, prepared by or for the selling party, optimised to present the most attractive possible case.
The assumptions buried in a developer yield projection typically include: 90%+ occupancy, growing annual rents, low management fees, and minimal void and maintenance allowances. Actual outcomes for investors who have purchased based on such projections frequently fall 30–50% short of projections, even on projects that complete on time and to specification.
Independently verify rental comparables. Commission your own financial model. Do not rely on the seller's numbers.
Mistake 8: Not Protecting Off-Plan Deposits
Off-plan purchases require stage payments before the property is built or completed. If the developer fails, becomes insolvent, or simply fails to deliver, you need legal protection to recover your money.
In Dubai, RERA requires developers to hold stage payments in escrow accounts. In Spain, developers are legally required to provide bank guarantees for stage payments. In other markets, buyer protections are less robust or less consistently enforced.
Understanding what protection exists for your deposit, and obtaining specific contractual and bank-backed protections before paying anything, is essential for off-plan purchases. See our guide to how to verify a developer before you buy.
Mistake 9: Ignoring Currency Risk
Buying an overseas property means holding an asset denominated in a foreign currency. Exchange rate movements can materially affect returns when measured in your home currency — and over a typical 10-year holding period, movements of 20–30% in major currency pairs are not unusual.
Many investors who focus intensely on rental yields and capital values completely ignore this dimension of their investment. Understanding, quantifying, and managing currency exposure is fundamental to international property investment.
See our comprehensive guide to exchange rates and overseas property.
Mistake 10: Choosing the Wrong Location Within a Market
Markets are not homogeneous. "Investing in Greece" or "investing in Thailand" is not a strategy — the outcomes in different cities, regions, and neighbourhoods within those markets can be wildly divergent.
Understanding which specific locations have the fundamental drivers of rental demand and capital growth — and which look attractive at the surface level but lack depth — requires local research. Tourist hotspots may have high seasonal yield potential but also high supply, heavy regulation, and illiquid resale markets. Secondary city residential may offer better value but require longer to exit.
Our best areas guides cover this in depth: Dubai, Greece, Spain, Thailand, Bali, UK, Cyprus, and Egypt.
Mistake 11: Buying Without a Clear Investment Strategy
Are you buying for income, for capital growth, for personal use, for residency rights, or for a combination? The answer determines what you should buy, where, in what structure, with what financing, and with what exit horizon. Buying without clarity on this produces a portfolio of properties that neither collectively nor individually achieves any coherent goal.
Mistake 12: Neglecting Tax Planning
The tax implications of overseas property — on rental income, on capital gains, on inheritance — are complex and vary by market and by your personal circumstances. Many investors discover their tax position only when they file their first return or try to sell.
Tax planning after you have already purchased has far fewer options than tax planning before. Key questions to answer before buying: what is my rental income tax position in the property country? What is my reporting obligation in my home country? How will the property be taxed on my death? What is the capital gains tax on exit?
For comprehensive guidance, see our guides to double tax treaties, rental income tax for international landlords, and tax residency vs domicile for property investors.
Mistake 13: Over-Leveraging
Using debt to buy property amplifies returns when markets rise and amplifies losses when they fall. Investors who over-leverage — particularly at variable rates or with short-term refinancing requirements — can find themselves in acute difficulty when interest rates rise or property values fall below the loan value.
The right level of leverage depends on: rental yields versus interest costs (interest cover ratios), the stability of the market, your personal liquidity, and your risk tolerance. As a principle, the investment should be cash-flow positive even after debt service and should be stress-tested against a 25–30% fall in rental income.
Mistake 14: Not Checking Short-Let Regulations
The short-let regulatory environment is changing rapidly in many markets. Spain, Greece, and Bali have all tightened rules in recent years. Some areas that were open to Airbnb-type rentals have imposed licence moratoriums, meaning new licences are unavailable.
Buying a property for short-let income without checking whether a valid tourist licence can be obtained — or maintaining one — can destroy the investment case entirely. Always verify licensing position independently before buying for short-let. See our guides on short-let rules for Spain, Greece, Bali, Thailand, Dubai, and UK.
Mistake 15: Buying in an Illiquid Market at a Premium Price
Some niche markets or property types attract significant initial interest from foreign buyers and seem to offer strong growth. When the cycle turns and buyers want to exit, they discover that the resale market for foreign-purchased property in that location is very thin — and discounts of 20–40% are needed to find a buyer.
Always ask: how many foreign buyers are selling in this market today? What is the typical time to sell? How does the resale price compare to the original purchase price (not the developer's asking price)? Can you sell to a local buyer if no foreign buyer emerges?
Mistake 16: Poor Estate Planning
Dying owning property in multiple countries without proper estate planning can leave heirs facing probate procedures in several jurisdictions simultaneously, potential inheritance taxes in multiple countries, forced heirship rules that override your wishes, and lengthy and costly legal processes.
Estate planning for international property requires a specialist with cross-border expertise. A will valid in the UK may not be recognised or may not achieve your intentions in Spain, Thailand, or Indonesia. See our guide to estate planning for international property investors.
Mistake 17: Choosing a Property Manager on Price Alone
The cheapest management option frequently delivers the worst outcomes. A poor manager means higher voids, worse tenant quality, deferred maintenance that becomes expensive, and poor tenant relations that lead to disputes.
Good property management is one of the highest-return investments you can make in the ongoing performance of your property. Evaluate managers on track record, client references (specifically overseas clients), systems and technology, and fee transparency — not just headline cost.
Mistake 18: Not Visiting the Property Before Buying
Photographs and virtual tours are marketing tools. They do not show the noise from a nearby road, the building site going up next door, the quality of the building management, the actual view from the specific unit you are buying, or the character of the neighbourhood at different times of day and night.
Visit before you buy. If that is impossible, commission an independent inspection report. Buying blind based on digital marketing materials is a significant and unnecessary risk.
Mistake 19: Ignoring the Resale Market for Foreign Buyers
When you buy a property that can only be sold to other foreigners (due to legal restrictions, location characteristics, or market dynamics), your exit options are structurally limited. If sentiment among foreign buyers in that market turns — due to regulatory changes, currency moves, geopolitical events, or simple shifts in fashion — your holding becomes very difficult to exit.
In every market, understand whether there is a domestic buyer market for your property as well as a foreign one. A property in central Athens that a Greek family would also buy is fundamentally more liquid than a foreign-only villa development in a remote coastal area.
Mistake 20: Underestimating the Importance of Good Advice
International property investment is complex. The legal frameworks are different, the tax implications are material, the currency risk is real, and the information asymmetries between local sellers and foreign buyers are significant. The professionals around you — lawyer, tax adviser, financial adviser, currency specialist, property manager — substantially determine the quality of your outcome.
The investors who consistently make the best decisions are not necessarily the smartest or the most experienced. They are the ones with the best team around them and the discipline to take professional advice before acting.
