Buying a property is a significant decision. Beyond the location, floor plan and asking price, there is a considerable amount of information behind a property that a buyer should understand before committing to a purchase.
This is where due diligence comes in.
Property due diligence is the process of reviewing the ownership, documents, physical condition, financial obligations, surrounding circumstances and other relevant details of a property before completing a transaction.
The extent of the review will depend on the property. A condominium unit, a house and lot, vacant land, and a larger estate can each involve different considerations.
Some checks are straightforward. Others may require assistance from a lawyer, engineer, accountant, property inspector or other qualified professional.
The purpose is simple: to make sure you have a clear understanding of the property before you buy it.
1) Verify Ownership
The first question is straightforward:
Who owns the property?
For titled property, the registered owner should be identifiable from the title. The name of the seller or sellers should correspond with the ownership documents, and the person handling the transaction should have the proper authority to act on the owner’s behalf.
This becomes particularly important when a property is being sold by:
- multiple owners
- an authorized representative
- a corporation
- an estate
- an attorney-in-fact under a Special Power of Attorney
- an heir or family member acting on behalf of other parties
If someone other than the registered owner is signing documents or negotiating the sale, the authority to do so should be properly established.
The ownership structure can also become more involved when the property has been inherited, is jointly owned, or forms part of a corporate transaction.
This is one area where the documents should tell the same story as the people involved in the sale.
2) Review the Title
For titled property, the Transfer Certificate of Title (TCT), Original Certificate of Title (OCT) or Condominium Certificate of Title (CCT) provides important information about ownership and the property itself.
A buyer should obtain a Certified True Copy (CTC) rather than relying solely on a photocopy or image supplied by the seller.
The Land Registration Authority specifically identifies the Certified True Copy of a title as a document that may be used for due diligence in buying, selling and leasing property. Their portal also allows the public to request CTCs of TCTs, OCTs and CCTs online.
The title contains information and annotations that may be relevant to the transaction, including registered ownership and interests affecting the property.
This is where a proper review becomes important. A title can look perfectly straightforward at first glance, but the annotations at the back can tell a different story. A mortgage, adverse claim, restriction or other annotation may have implications for the transaction, which is why the document deserves more than a quick glance before you proceed.
The title is one of the most important documents in a property transaction, but it is only one part of the due-diligence process.
3) Compare the Title With the Other Property Documents
The information on the title should be consistent with the other documents relating to the property.
Depending on the transaction, these may include:
- Tax Declaration
- Real Property Tax records
- Condominium or subdivision documents
- Certificate of ownership issued by homeowners’ association
The Bureau of Internal Revenue’s current ONETT requirements, for example, include certified copies of the applicable title and Tax Declaration as part of the documentation for real-property transfers.
For a buyer, the practical point is to make sure the documents describe the same property.
The lot area, unit details, ownership, property description and other relevant information should be consistent.
Where something doesn’t line up, it is worth understanding why before moving forward.
4) Check the Property’s Tax and Financial Obligations
A property may also carry financial obligations that need to be addressed as part of the transaction, including real property taxes, condominium or association dues, special assessments, utility balances or an existing mortgage. For condominium properties in particular, it is worth understanding both the current monthly dues and whether there are outstanding balances or assessments.
The same principle applies to subdivisions and other managed developments.
The asking price is usually the number that gets the most attention. The smaller, recurring costs are easier to overlook until you’ve already bought the property. Knowing what comes with the purchase gives you a much more realistic picture of what ownership will actually cost.
5) Inspect the Physical Property
Documents can tell you who owns a property and provide important information about its legal and financial status.
They cannot tell you everything about what it is like to own the property. A house can photograph beautifully and still have a roof that needs attention. A recently renovated kitchen can look immaculate while older plumbing sits behind the walls. Even a well-maintained condominium unit is part of a much larger building whose condition matters too.
This is why seeing the property in person—or having the right professional inspect it—can reveal things that no document or listing photograph can.
For a house, this may mean looking at the condition of the structure, plumbing, electrical systems, finishes, appliances and other improvements.
For a condominium, the review can extend beyond the unit itself.
The condition of the building’s common areas, elevators, amenities, utilities, parking facilities and other shared infrastructure can affect the ownership experience.
For older properties, renovation history can also be relevant.
A recently renovated home may look completely different from the property described in its older documents. Understanding what was changed and how the work was carried out can form part of the overall review.
For larger or more upscale properties, buyers may choose to engage an engineer, architect, interior designer or other specialist to assess specific aspects of the property.
6) Understand the Building or Development
When you buy into a condominium or subdivision, you’re also buying into the environment created by the people who manage and maintain it. The quality of that environment can have as much influence on everyday life as the four walls of the property itself.
For condominiums, this means looking beyond the unit itself. Building management, maintenance, amenities, common areas, parking and the level of condominium dues all form part of the ownership experience. Buyers should also understand the development’s rules around pets, renovations, leasing and other uses that may be relevant to them.
The same applies to subdivisions, where homeowners’ association rules and development restrictions can affect how a property is used.
These details can become particularly important when the buyer’s intended use involves leasing, renovations, pets, home businesses or other specific requirements.
7) Look Beyond the Property Line
A property does not exist in isolation.
The surrounding area can affect how enjoyable the property is to live in and how attractive it may be to future buyers or tenants.
Consider the broader location:
How accessible is it?
What surrounds it?
What developments are taking place nearby?
Are there major infrastructure projects planned for the area?
Could the surrounding environment change?
This can be particularly important when a property’s value is partly tied to a view, privacy, quiet surroundings, open space or low-density environment.
A vacant lot next door may eventually become another building. A new road may improve accessibility. A commercial development may bring more convenience—or more traffic. It’s vital to know whether the serene sea view from your villa might soon be obstructed, or if an upcoming commercial zone could enhance property values in the neighborhood.
Understanding the surrounding area is therefore part of understanding the property itself.
8) Consider How the Property Can Be Used
Before buying, make sure the property can be used in the way you intend. Depending on the property and location, this may involve zoning, subdivision restrictions, condominium or homeowners’ association rules, permitted uses, leasing restrictions, building restrictions or requirements for future renovations.
A property can be perfectly suited to one buyer and completely wrong for another.
Someone buying a family home may care about schools, parking and future renovations. An investor may be more concerned with leasing rules and rental demand. A buyer planning a major renovation may need to understand restrictions that another buyer would never encounter.
9) Study the overall Market
Due diligence also extends to the property’s financial context.
An asking price is an invitation to negotiate, not proof of value.
A ₱50 million asking price doesn’t become a ₱50 million property simply because it has been listed at ₱50 million. Look at comparable properties, recent transactions where available, the property’s condition and the features that actually differentiate it from the competition.
For a condominium, the most useful comparisons may be other units within the same building or nearby developments. For a house, land size, improvements, street location and neighborhood may matter more.
The objective is to understand where the property sits within its market, rather than relying on a single comparable or a generic price-per-square-meter figure. For many buyers, the purchase is also a significant investment, so understanding how the property compares with the broader market can be just as important as understanding the property itself.
10) Determine the Total Cost of Ownership
The purchase price is the obvious number. Ownership has a longer tail.
Depending on the property, ownership costs can include taxes, condominium or association dues, insurance, utilities, maintenance, repairs, renovations, property management and financing. Larger homes may also carry substantial staffing and upkeep costs, while investment properties need to account for leasing expenses and periods without a tenant.
11) Review the Sale Agreement
The property may have looked perfect during the viewing, but the transaction itself still needs to make sense on paper.
Before signing, understand the agreement that governs the transaction.
Depending on the stage and structure of the purchase, this may include an Offer to Purchase, Reservation Agreement, Contract to Sell, Deed of Absolute Sale, or other relevant documents.
The agreement should clearly establish the important commercial terms of the transaction, including the purchase price, payment schedule, conditions, timelines and responsibilities of the parties.
It should also be clear what happens if certain conditions are not met or the transaction does not proceed.
This is where having the appropriate professional review the documents can be particularly valuable. A real estate broker can help explain the practical aspects of a transaction, while a lawyer can provide legal advice on the documents and obligations involved.
Due Diligence Looks Different for Every Property
There is no single checklist that applies perfectly to every property.
A condominium unit may require close attention to the building, association rules and condominium documents. A house and lot may require more extensive review of the land, improvements, boundaries and physical condition. Vacant land can bring its own questions around access, use and development.
The more complex the property, the more important it becomes to understand the details before committing to the transaction.
This is also why due diligence is usually a process rather than a single document check.
When Should You Start Due Diligence?
Ideally, due diligence begins before you make a substantial financial commitment.
Some buyers begin researching a property as soon as they identify one they are seriously considering. Others conduct more detailed checks after the seller accepts an offer and before signing binding documents.
The appropriate timing depends on the transaction and its terms.
What matters is leaving enough room to review the relevant information before the purchase becomes difficult or costly to change.
Who Can Help With Property Due Diligence?
Different professionals bring different expertise to a property transaction.
A real estate broker can provide market knowledge, comparable properties, transaction guidance and information about the property and its surrounding market.
A lawyer can review legal documents, ownership structures and contractual matters.
An accountant or tax professional can advise on applicable taxes and financial considerations.
An engineer, architect or property inspector can assess the physical condition of a property where a more detailed inspection is appropriate.
You may not need every professional for every purchase. The appropriate level of review depends on the property, the transaction and the buyer’s circumstances.
Final Thoughts
A property can look perfect on paper and still deserve a closer look.
That doesn’t make due diligence complicated. It simply means taking the time to understand the property from several perspectives before committing to it.
For most buyers, the process starts with asking the right questions and knowing which areas deserve closer attention. From there, the appropriate professionals can help verify the details and guide the transaction through to completion.
A well-informed purchase starts long before the signing of the Deed of Absolute Sale.
