Due Diligence Explained

The Complete Guide to Protecting Yourself Before Buying Property Abroad

Property Guide by Slide'N Doors

Introduction

Buying a property is one of the biggest financial decisions most people will ever make.

It's exciting, but it's also easy to become emotionally attached to a home and overlook important details.

This is where due diligence comes in.

Due diligence simply means carrying out the right checks before you commit to buying.

The more you investigate before signing a contract, the less likely you are to face expensive surprises later.

What Does Due Diligence Mean?

Due diligence is the process of checking everything you reasonably can before completing the purchase.

That includes:

• The property.
• The legal paperwork.
• The land.
• The services.
• The access.
• The surrounding area.
• The seller.
• Future costs.

Think of it as reducing risk rather than finding reasons not to buy.

Don't Rush

One of the biggest mistakes buyers make is allowing themselves to be pressured.

You may hear things like:

"There's another buyer interested."

"You'll lose it if you don't leave a deposit today."

"This price is only available until tomorrow."

Take your time.

No genuine seller should object to sensible due diligence.

How Long Does Due Diligence Usually Take?

There isn't a single answer, as the timeframe varies depending on the country, the type of property and whether you're buying with cash or finance.

A straightforward purchase may only require a few weeks, while more complex transactions can take considerably longer.

Typical due diligence periods are often:

These are general guides only. Actual times vary depending on the property, legal requirements, financing and the parties involved.

Should You Speed Up Due Diligence?

Sometimes a seller or estate agent may ask if you can complete more quickly.

You may hear things like:

• "There's another buyer interested."
• "Can we shorten the due diligence period?"
• "We need to exchange as soon as possible."
• "We'd like to complete before the end of the month."

While there may be genuine reasons for wanting a faster sale, you should never rush your due diligence simply because someone asks you to.

A shorter due diligence period gives you less time to:

• Review legal documents.
• Arrange surveys and inspections.
• Check boundaries.
• Test utilities.
• Investigate the local area.
• Obtain specialist reports.
• Ask questions and receive answers.

Buying a property is one of the biggest financial commitments you'll ever make. Spending a little more time carrying out proper checks is almost always better than discovering an expensive problem after you've completed the purchase.

Can the Due Diligence Period Be Extended?

Sometimes unexpected issues arise during the buying process.

For example:

• You're waiting for survey results.
• Your lawyer needs additional documents.
• Further inspections are recommended.
• A title issue is being investigated.
• Repairs are still being negotiated.

In many cases, buyers and sellers can agree to extend the due diligence period if everyone is willing. Any extension should be agreed in writing and handled through your legal representatives where appropriate.

Good communication is usually far better than rushing to meet an unrealistic deadline.

Build the Right Team

Buying abroad often means relying on local experts.

Consider using:

• An independent lawyer.
• A qualified surveyor.
• An architect where appropriate.
• A property inspector.
• An engineer if required.
• A trusted local accountant or tax adviser.

Choose professionals who work for you, not the seller.

Check the Legal Documents

Ask your lawyer to verify:

• Ownership.
• Property title.
• Boundaries.
• Easements.
• Rights of way.
• Outstanding debts.
• Mortgages.
• Restrictions.
• Planning permissions.

Never rely on verbal assurances.

Inspect the Property Properly

Look beyond fresh paint and attractive furniture.

Check:

• Roof.
• Walls.
• Damp.
• Cracks.
• Windows.
• Doors.
• Plumbing.
• Electrical systems.
• Air conditioning.
• Water pressure.
• Drainage.
• Septic systems.
• Signs of termites or woodworm.

Small cosmetic issues are normal.

Hidden structural or legal problems can become expensive.

Test Everything

Don't simply look.

Use it.

Turn on every tap.

Flush every toilet.

Open every window.

Test every light.

Run the air conditioning.

Lock every door.

Operate the garage door.

Open gates.

Walk every path.

The more you test before buying, the fewer surprises you'll discover after moving in.

Check the Land

The land is just as important as the building.

Ask:

• Are the boundaries clear?
• Are there any encroachments?
• Is there any flood risk?
• Could neighbouring land be developed?
• Are there protected trees?
• Are retaining walls in good condition?

Investigate the Area

Spend time around the property.

Visit:

• Morning.
• Afternoon.
• Evening.
• Weekends.
• During heavy rain if possible.

Ask yourself:

• Is it noisy?
• Are dogs constantly barking?
• Is there heavy traffic?
• Does the area feel safe?
• Do neighbours look after their properties?

The property may be perfect.

The location may not be.

Think About Everyday Living

Imagine actually living there.

Ask yourself:

• Can deliveries reach the property?
• Where will visitors park?
• Is there reliable internet?
• How are bins collected?
• Can emergency services access the property?
• Where is the nearest supermarket?
• Hospital?
• School?
• Fuel station?

Sometimes it's the practical things that matter most.

Consider Running Costs

Don't just budget for the purchase price.

Also ask about:

• Property taxes.
• Community fees.
• Insurance.
• Water.
• Electricity.
• Internet.
• Gardening.
• Pool maintenance.
• Security.
• Road maintenance.

Sometimes a cheap property becomes expensive to own.

Wayne's Tip 💡

During our own property journey in Costa Rica, one thing I learned is not to rely solely on what you're told—verify it for yourself wherever possible.

If the property has a private water supply, I'd consider carrying out your own basic water test as part of your due diligence. A simple testing kit costs very little online and can provide an early indication of water quality before you complete the purchase. While it's no substitute for professional laboratory testing, it's another sensible check when making such an important investment.

The same principle applies throughout the buying process.

Don't be afraid to ask questions, request documents or test things yourself. Good sellers, estate agents and professionals should welcome sensible due diligence.

Keep Records

Save copies of:

• Emails.
• Contracts.
• Receipts.
• Surveys.
• Water test results.
• Inspection reports.
• Photos.
• Videos.
• Property listings.

Good records can help resolve misunderstandings later.

Questions Every Buyer Should Ask

Before buying, ask yourself:

• Have I independently verified everything?
• Have I visited more than once?
• Have I spoken to neighbours?
• Has my lawyer completed all legal checks?
• Have I tested the property's services?
• Do I understand all ongoing costs?
• Am I buying with my head as well as my heart?

Your Due Diligence Library

Due diligence isn't one single check—it's lots of small checks that, together, help you make a better-informed decision.

That's exactly why we've created the Slide'N Doors Property Guides.

Rather than trying to squeeze everything into one guide, we've built a growing library covering the questions buyers ask before, during and after purchasing a property abroad.

Each guide focuses on a specific topic, helping you carry out more thorough due diligence and reducing the risk of costly surprises later.

Some of the guides available include:

• Can I Legally Buy Property Abroad?
• Parking Explained
• Water Supplies Explained
• Can I Drink the Water?
• Hot Water Systems Explained
• Septic Systems Explained
• Capital Gains Tax Explained

…and many more are being added regularly.

We encourage every buyer to spend some time exploring these guides before committing to a purchase. The more knowledge you have, the more confident your decisions will be.

After all, good due diligence isn't about finding reasons not to buy a property—it's about making sure you're buying the right one.

Wayne's Final Thoughts

Buying property should be exciting, but excitement should never replace careful preparation.

A few extra days—or even weeks—spent carrying out proper due diligence could save you thousands in unexpected costs and give you confidence that you're making the right decision.

Never let someone else's urgency become your emergency.

If a seller genuinely wants to sell their property, they should understand that carrying out sensible checks is simply part of the buying process.

The best buyers aren't the fastest buyers.

They're the ones who ask the most questions, verify the answers and make informed decisions with confidence.
