Property Due Diligence Checklist for Buying Abroad (2026)
Most cross-border property problems are avoidable. They come from skipping checks — not from bad luck. Here is the checklist that catches them.
Due diligence is the work you do before you are committed — confirming that the property is what it claims to be, that the seller can legally sell it, and that there are no hidden liabilities you would inherit. In your home country a lot of this is familiar; abroad, the rules, registries and risks differ, and the buyer carries more responsibility. This checklist covers what to verify, in roughly the order you should verify it, so you commit money only once the property has passed.
Ownership and title
Start with proof that the seller actually owns what they are selling. Get an up-to-date extract from the land or property registry showing the registered owner, the exact boundaries, and the legal description. The name on the registry must match the seller (or their authorised representative). For inherited or jointly-owned property, confirm that every owner consents to the sale — a missing co-owner can void the deal later.
Debts, liens and charges
Property usually carries its encumbrances with it. The registry extract should reveal mortgages, court charges, tax liens or easements attached to the property. Ask specifically about unpaid property taxes, utility arrears, and community or building fees, which can transfer to you on purchase. Never assume a clean title — have your lawyer confirm there is nothing registered against it as of the day you complete.
Permits, planning and legality
Confirm the property was built and is used legally. Check that construction permits, occupancy or habitation certificates, and any extensions or pools were approved. Unpermitted building work is common and can mean fines, forced demolition, or inability to resell. For land, verify the zoning allows what you intend (residential, tourist rental, or development) and that there are no protected-zone or border-area restrictions on foreign buyers.
The contract
Read the preliminary contract before you pay a deposit, ideally with your own lawyer. It should state the price, what is included, the completion date, and the precise conditions under which your deposit is refundable. Make completion conditional on a clean title check and, if relevant, financing. Watch for clauses that let the seller keep your deposit on vague grounds, or that shift unusual costs onto the buyer.
Costs and taxes
Map the full cost of ownership, not just the price. Purchase taxes, notary and registration fees, legal fees and agency commission typically add a meaningful percentage on top. Then confirm the ongoing taxes: annual property tax, and any non-resident or rental-income tax if you will let it out. Our country tax guides cover the specifics — the point of due diligence is that none of these should surprise you after signing.
The people and the money trail
Verify the people you are relying on: that your lawyer is independently licensed and not connected to the seller, that the agent is registered, and for new builds, that the developer has a track record and the project has the required guarantees. Confirm exactly how and to whom money is paid — a regulated escrow or notary account — and keep every receipt and signed document. Good paperwork is what protects you years later.
FAQ
What does due diligence mean when buying property?
It is the verification you do before committing: confirming ownership and clean title, checking for debts and liens, confirming the building is legal and permitted, reviewing the contract, and mapping all taxes and costs. Done properly it removes almost all of the avoidable risk in a purchase.
Who carries out due diligence — me or a lawyer?
An independent local lawyer does the legal checks (title, liens, permits, contract), and you should commission them directly rather than rely on the seller's side. You still drive the process: deciding what matters, asking questions, and refusing to pay until each item passes. For physical condition, a surveyor or inspector covers what a lawyer does not.
How long does property due diligence take?
Typically a couple of weeks for a standard residential purchase once documents are requested, longer for land, developments, or complicated ownership. The timeline depends on how quickly the registry and seller produce documents. Never let a tight deadline pressure you into skipping checks.
What are the biggest red flags?
An owner name that does not match the registry, reluctance to provide title documents, unpermitted construction, pressure to pay quickly or to a private account, and a deposit contract where you lose your money on vague conditions. Any one of these is a reason to pause.
Can I do due diligence remotely?
Yes. Registry extracts, contracts and permits can be reviewed remotely by your lawyer, and a local inspector can check the property physically on your behalf. See our guide on buying property abroad remotely for how to combine these into a safe remote purchase.
