If you are planning to sell your flat, buy a resale flat, or buy private property while owning an HDB flat, one date matters more than almost any other: when the Minimum Occupation Period (MOP) ends. Get it wrong and you may find yourself unable to proceed with a sale, or tied into a timeline that does not work. This guide shows you how to check HDB MOP status properly, step by step, whether you are the owner or the buyer.
We will not re-explain the MOP concept here. If you need the background, read the HDB Minimum Occupation Period (MOP) explained first. This article is about verification. It is general information, not legal advice, and HDB’s rules and portal can change, so treat HDB’s official website as the final word.
Why You Should Verify Rather Than Calculate
Many owners count five years from the day they collected their keys and assume that is the answer. Sometimes it is. But there are reasons the official date may differ from your own sum:
- The start date depends on how you bought. For many new flats the clock starts at key collection, while for resale flats it usually runs from the resale completion date. Different schemes and grants can carry their own conditions.
- Periods away may not count. If the household did not physically occupy the flat for a period, that time may not count towards the MOP.
- Grants and schemes add conditions. Some housing grants and schemes have their own occupation requirements.
- Ownership changes can affect records. Adding or removing an owner, or a change after divorce, can involve a fresh look at the flat’s conditions.
HDB’s own records are what HDB will use when it processes a resale. So the safe approach is simple: check the official date, then plan around it.
Step-by-Step: How Owners Check HDB MOP
If you own the flat, you can view its details yourself.
- Log in to the HDB Flat Portal with Singpass. Singpass is Singapore’s national digital identity login. The HDB Flat Portal is HDB’s online service for buying, selling and managing flats, and it replaced the older My HDBPage.
- Find your flat’s ownership or sale section. Look for the area that covers your flat details or selling your flat. The exact menu labels can change, but the information is usually under your flat’s records or the resale journey.
- Run the eligibility check to sell. The portal’s selling journey includes a check of whether you are eligible to sell, which takes the MOP into account. It typically shows when your flat will meet the MOP if it has not yet.
- Note the date and take a screenshot. Record the exact date shown, the date you checked, and keep a copy for your planning.
- Check every co-owner’s situation. If the flat is jointly owned, confirm that nothing in any owner’s circumstances affects eligibility, such as an outstanding obligation linked to a grant.
- Contact HDB if anything looks wrong. If the date does not match your records, or you spent time living elsewhere, ask HDB through its official channels before you make plans.
Sellers should also know the order of steps. HDB requires sellers to register an Intent to Sell through the portal before granting an Option to Purchase (OTP), the document that gives a buyer the right to buy the flat. Check the current waiting period and conditions on HDB’s site, and do not grant an OTP before your flat has met its MOP.
Step-by-Step: How Buyers Verify a Seller’s MOP
As a buyer, you cannot log in to the seller’s account, so verification relies on the seller and their agent.
- Ask early. Before you put serious time into a flat, ask the seller or agent when the flat met, or will meet, its MOP.
- Ask to see the official record. A genuine seller can show the eligibility result from the HDB Flat Portal. Look for the flat address and the relevant date.
- Check the listing’s claims. Listings that say “MOP reached” or “MOP soon” are marketing. Treat them as a starting point, not proof.
- Confirm the Intent to Sell. Ask whether the seller has registered an Intent to Sell and when.
- Use your own agent or lawyer. If you are working with a property agent registered with the Council for Estate Agencies (CEA), ask them to confirm the seller’s eligibility before you pay the option fee.
- Plan your own timeline. If you are selling your current flat at the same time, line up both dates carefully.
The table shows what each side checks and why.
| Who | What to check | Where | Why it matters |
|---|---|---|---|
| Owner selling | Date the flat meets MOP | HDB Flat Portal eligibility check | You cannot sell on the open market before then |
| Owner buying private property | Whether your current flat has met MOP | HDB Flat Portal and HDB rules | HDB owners generally must meet MOP before buying private property |
| Resale buyer | Seller’s MOP and Intent to Sell | Seller’s portal record, via agent | Avoids an OTP that cannot proceed |
| Buyer planning ahead | The MOP that will apply to you after purchase | HDB’s rules for resale buyers | Affects when you can sell or buy private later |
Red Flags That Should Make You Pause
Most transactions are straightforward, but slow down if you notice any of these:
- The seller avoids showing official records and relies only on verbal assurances.
- The dates do not add up. For example, the flat looks like a recent completion but is advertised as having met its MOP.
- There has been a recent ownership change and nobody can explain whether it affected eligibility.
- Pressure to grant or exercise an OTP quickly before the MOP or Intent to Sell steps are clear.
- Overseas periods. If the owners mention living abroad during the ownership, ask how that has been treated.
None of these automatically means something is wrong, but each is a reason to verify with HDB before money changes hands.
Planning Around the MOP Date
Once you know the date, work backwards. Selling a flat involves several stages, from valuation to resale application and completion, as covered in selling your HDB flat: the process explained. If you also need to buy your next home, read selling and buying a home at the same time to plan your financing and any temporary housing.
A few practical tips:
- Start research months ahead, but do not grant an OTP until you are eligible.
- Recheck the portal close to your target date, in case anything has changed.
- Keep all screenshots and letters in one folder with dates.
Checking your MOP takes minutes. Assuming it can cost you a deal. Make the official check the first step of any plan to buy or sell, and confirm anything uncertain directly with HDB.
Frequently Asked Questions
What happens if I grant an OTP before my flat reaches MOP? The sale cannot properly proceed, and you may be tied into a timeline that does not work. HDB requires the flat to meet its MOP and an Intent to Sell to be registered first. Check the current rules on HDB’s website and do not grant an OTP until you are eligible.
Does time spent living overseas count towards my MOP? Not necessarily. If the household did not physically occupy the flat for a period, that time may not count. If you have lived abroad during ownership, ask HDB through its official channels how it has been treated before you plan a sale.
Can I buy private property before my HDB flat reaches MOP? Generally no. HDB owners usually must meet the MOP before buying private property. Check your flat’s status on the HDB Flat Portal and confirm the rules with HDB, since conditions can differ by scheme, grant and household situation.
How long before my MOP date should I start preparing to sell? Start research months ahead, such as valuation, financing and where you will live next, but do not grant an OTP until you are eligible. Recheck the portal close to your target date in case anything has changed, and keep screenshots and letters in one dated folder.
What should I do if the MOP date on the portal looks wrong? Do not rely on your own calculation. Compare the date with your key collection or completion records, note any periods away, then contact HDB through its official channels and ask for clarification before making plans. Keep a screenshot and the date you checked.
