Condo Due Diligence in the Philippines: 2026 Buyer’s Guide

When Beth signed the reservation agreement for a resale studio along Shaw Boulevard, the unit checked every box she could see: move-in ready, priced below the going rate for the tower, a seller motivated to close before year-end. What she didn’t check — because no one told her to — was the condo corporation’s dues ledger. Three weeks before turnover, her broker found the previous owner was ₱187,000 behind on association dues. Under most master deeds, that debt follows the unit, not the person who ran it up. Beth talked the price down to cover it, but only because she caught it before signing, not after.

That gap — between what a listing shows you and what actually governs the unit — is where condo investments go wrong in the Philippines. A condominium isn’t just a piece of real estate; it’s a share in a shared corporation, bound by a master deed you probably haven’t read, financed by dues you haven’t verified, and sold by a developer whose paperwork you haven’t checked. Due diligence is the process that closes that gap before your money does. This guide walks through what that actually looks like — legally, financially, physically, and in terms of the people and rules that will govern your ownership for as long as you hold the unit.

Due diligence, in the simplest terms, is the process of verifying a property’s legal standing, financial health, and physical condition before you commit money to it. For a house-and-lot purchase, that mostly stops at the title and the structure. A condominium adds a layer that catches most first-time buyers off guard: you’re not just buying a unit, you’re buying a permanent seat in a shared corporation. Under Republic Act No. 4726 (the Condominium Act), every unit owner automatically becomes a shareholder in the condominium corporation that owns and manages the building’s common areas — the lobby, the elevators, the roof deck, the fire systems. That corporation’s financial health, its rules, and its legal disputes become yours the moment the title transfers, whether or not you ever read a page of its bylaws.

The due diligence checklist also shifts depending on what kind of unit you’re buying. A pre-selling unit doesn’t exist yet, so your verification effort goes almost entirely into the developer and its permits. A ready-for-occupancy (RFO) unit exists, so physical inspection and turnover documentation matter most. A resale unit carries years of financial and legal history attached to it — dues, liens, and whatever the previous owner did or didn’t pay — which is exactly the category that caught Beth off guard.

For pre-selling units, everything starts with the developer’s License to Sell (LTS). Under Presidential Decree No. 957 — the Subdivision and Condominium Buyers’ Protective Decree — a developer must register the project and secure an LTS from DHSUD before it can legally sell, market, or even accept a reservation fee for a unit. DHSUD only issues the license if the developer demonstrates good repute, financial stability, and posts a performance bond. You can check whether a specific project has one on DHSUD’s public “List of Projects with License to Sell” — if a project isn’t on it, that’s a reason to pause, not a reason to assume it’s just an oversight.

The Master Deed and Declaration of Restrictions matter just as much, whether you’re buying pre-selling or resale. Registered at the Registry of Deeds, the Master Deed is the document that legally creates the condominium and defines what you actually own — your exclusive unit plus an undivided share in the common areas. The Declaration of Restrictions sets the operating rules: use limitations, architectural guidelines, and often the rental and pet policies that a sales agent won’t necessarily walk you through. Read it before you sign, not after you’ve already told your Airbnb guests to expect a September move-in.

For resale units, title verification is the step most buyers skip because it feels redundant — the seller already has a copy, after all. It isn’t redundant. Go to the Registry of Deeds yourself and pull the Condominium Certificate of Title (CCT) directly, not the seller’s photocopy, and check it for liens, adverse claims, or annotations that a printed copy might not show clearly. Confirm the name on the title actually matches the person signing the deed of sale — a mismatch, even an innocent one involving an heir or an unregistered prior sale, can stall or void the transfer entirely.

The condo corporation’s financial health is the piece most buyers never think to ask about, and it’s exactly what caught Beth. Because the corporation is a SEC-registered non-stock entity, it files a General Information Sheet (GIS) and audited financial statements — ask for both. Look specifically at the dues collection rate (a building where a third of owners are delinquent has a maintenance and special-assessment problem waiting to happen), the size of the reserve fund relative to the building’s age, and whether any special assessments or litigation are pending. A request for a dues clearance certificate on the specific unit you’re buying should be non-negotiable before you finalize a resale purchase.

Then there’s the cost of ownership that doesn’t show up in the listing price:

On the return side, temper expectations with current data rather than a broker’s pitch deck. BSP’s new Residential Property Price Index (RPPI) — which replaced the older RREPI starting with the Q1 2025 release — put the median NCR condominium unit at roughly ₱5.32 million as of Q1 2026, with price growth recovering after a soft stretch in 2025. Rental yields vary meaningfully by district: BGC and Makati currently run toward the higher end of the Metro Manila range, while Ortigas trades a lower entry price for a somewhat wider yield spread depending on the specific building and unit size — treat any single yield percentage a seller quotes you as a starting point to verify, not a guarantee. And weigh all of it against Metro Manila’s oversupply picture: Colliers projects citywide condo vacancy reaching a record 25.6% by the end of 2026, up from 24.7% in Q1, as nearly 13,000 new units come online — almost double 2025’s completions. In an oversupplied market, a unit’s rental income depends far more on its specific location and building quality than on the citywide average.

No amount of paperwork substitutes for walking the unit yourself — and if you’re buying pre-selling, that means walking the developer’s other completed projects instead, since the unit you’re reserving doesn’t exist yet. For RFO and resale units, a proper inspection catches the kind of problems that only show up after move-in, when they’re your problem to fix.

Building age and maintenance history matter as much as the unit itself. Ask when the elevators were last modernized, whether any major structural or waterproofing repairs have been done recently, and — if you can get it — whether the building has an up-to-date engineering or fire safety inspection report on file. A well-maintained older building is frequently a better bet than a newer one with a thin reserve fund and a maintenance backlog already forming.

Verifying a developer’s DHSUD standing takes fifteen minutes and can save you years of frustration if a project stalls. Here’s the sequence:

Bank and Pag-IBIG accreditation is a useful secondary signal, not a substitute for the DHSUD check. If banks or Pag-IBIG have accredited a project for financing, it has typically already passed a layer of institutional scrutiny on the developer’s standing and the project’s documentation — worth asking about, especially for pre-selling projects still early in construction.

The condominium corporation that comes with your unit is a distinct legal entity — a SEC-registered non-stock corporation, governed by a board of at least five directors elected from among unit owners, filing its own GIS and audited financial statements annually. This is a different animal from a subdivision’s homeowners’ association, which falls under a different set of rules entirely, and it’s worth understanding the distinction before you assume “the HOA” handles everything the same way a friend’s subdivision does.

Beyond rental policy, house rules typically cover pets, renovation approval processes (most buildings require sign-off before you touch plumbing, electrical, or load-bearing elements), and move-in/move-out procedures. As a prospective buyer, you’re generally entitled to request recent board meeting minutes and financial reports — a board that stonewalls that request, especially during a resale transaction, is itself a red flag worth weighing.

The building matters, but so does everything around it. Zoning, flood exposure, and the infrastructure timeline for the area all shape both your day-to-day living experience and your resale case down the line — verify current DHSUD or LGU flood hazard mapping for the specific address, not just the district’s general reputation. Rental demand also varies meaningfully by district, and it’s worth going in with realistic, area-specific expectations rather than a single citywide number:

Most defective condo purchases don’t look suspicious at the viewing. They look like Beth’s studio — clean, priced right, seller in a hurry — and the problem only surfaces once you’re already committed. Watch for these before you sign anything:

Pulling everything above into one sequence:

• Verify the CCT (resale) or DHSUD LTS and Certificate of Registration (pre-selling) before paying anything beyond a fully refundable reservation fee
• Read the Master Deed and Declaration of Restrictions, not just the sales brochure
• Request the condo corporation’s GIS, audited financial statements, and a dues clearance certificate on the specific unit
• Calculate total cost of ownership — dues, RPT, reserve fund contributions, insurance — not just the purchase price
• Inspect the unit and common areas in person, or through a trusted representative if buying remotely
• Confirm the building’s rental policy in writing if your plan depends on rental income
• Check flood risk and zoning for the specific address, not just the district’s general reputation

Working with a broker licensed under Republic Act No. 9646, the Real Estate Service Act, matters more here than the paperwork suggests. RESA created the Professional Regulatory Board of Real Estate Service (PRBRES) specifically to license and regulate brokers, salespersons, appraisers, and consultants — a licensed broker can run much of this verification on your behalf, which matters enormously if you’re an OFW or overseas buyer unable to walk the unit or visit the Registry of Deeds yourself. Before engaging anyone, ask for their PRC license number and verify it independently rather than taking a business card at face value.

Beth’s ₱187,000 surprise was avoidable, and it’s the same story behind most condo purchases that go wrong in the Philippines: not fraud, usually, just a document nobody asked to see until it was too late to matter. Due diligence isn’t a formality that slows down a good deal — it’s the process that tells you whether the deal is actually good before you’ve paid for the privilege of finding out the hard way. Verify the developer, read the Master Deed, check the corporation’s books, walk the unit, and confirm the rules match your plans for it. Everything else in condo investing is easier once that foundation is solid.
