How to Check If a Resale Flat Is Within 4km of Parents for PHG
A practical agent workflow to verify PHG proximity using HDB’s official distance enquiry, confirm the correct home address, and avoid wrong-unit advice before an offer.
Use HDB’s official PHG distance enquiry to check the exact resale flat against the parents’ or child’s actual residential home address, then use that result to screen the unit before any offer, option fee, or OTP exercise.
If a buyer wants PHG because they plan to live near parents or children, do not rely on a rough Google Maps estimate. Use HDB’s official Distance Enquiry for Proximity Housing Grant with the exact resale flat address and the relevant family member’s actual residential home address. That gives you a cleaner pre-offer answer and reduces the risk of advising on the wrong unit.
What does the PHG 4km rule actually mean for resale buyers?
For PHG, the resale flat must be within 4km of the relevant parents’ or children’s home address. This is a proximity screen, not a full grant approval by itself.
In practical terms, the PHG 4km rule is a flat-to-home check. The question is not whether the unit is in the same town, near the same MRT station, or generally “close by.” The question is whether that specific resale flat falls within 4km of the relevant family member’s home address for PHG purposes.
That matters because buyers often shortlist by area first. A unit in the same estate can still fail the proximity check, while a unit in a neighbouring estate may still pass. Agents should therefore avoid saying “this whole neighbourhood should qualify” unless each shortlisted unit has been checked.
The best client-facing framing is simple: “PHG proximity is checked unit by unit. We still need to verify this exact flat against your parents’ home address.” For the broader PHG framework, see HDB’s Proximity Housing Grant page and PropKaki’s PHG eligibility guide.
Insight for agents: proximity is not a neighbourhood claim; it is an address-level check. For a broader overview, see HDB Housing Grants in Singapore: What Agents Need to Know About EHG, Family Grant, PHG and Singles Support.
What address should you use when checking the parents’ home?
Use the parents’ actual residential home address. Do not use a mailing address, an old address, or the address that happens to make the flat look eligible.
The most common PHG mistake is not the map tool. It is the wrong address.
What matters is where the parents or children actually live. Agents should not assume this from an old NRIC address, a correspondence address, or a vague statement like “they stay around Bishan.” Ask for the full residential address before screening the flat.
Be more careful when the family setup is not straightforward, for example:
- the parents moved recently
- they are temporarily staying with relatives
- they own one property but live in another place
- the buyer casually refers to a former home address
In these cases, pause before giving a view on PHG. A fast but wrong answer is worse than a slower accurate one. If needed, point the client to the official SupportGoWhere PHG page and verify the live case with HDB before the buyer commits.
Practical takeaway: confirm the residential address first, then check distance. Do not reverse that order. For a broader overview, see Proximity Housing Grant (PHG): Eligibility, 4km Rule and Who Can Apply.
How can an agent verify if a flat is within 4km of the parents’ home?
Use HDB’s Distance Enquiry for Proximity Housing Grant with the exact flat address and the exact residential home address. Save the result and use it as your working reference for the deal.
The cleanest workflow is straightforward:
- Get the exact resale flat address the buyer is considering.
- Confirm the parents’ or child’s actual residential home address.
- Run HDB’s Distance Enquiry for Proximity Housing Grant.
- Save a screenshot or printout of the result for your file and client follow-up.
- Reconfirm the same addresses before the buyer makes an offer, pays the option fee, or exercises the OTP.
This matters because PHG screening is most useful before money and expectations are locked in. A saved result is not a legal substitute for HDB’s eventual assessment, but it is a practical record if the client later asks why you shortlisted or ruled out a unit.
Example: if a buyer is deciding between two nearby resale flats, run the HDB check on both exact addresses before discussing which one better fits the grant plan. That is much safer than saying both “should be within range” based on the same neighbourhood. For a broader overview, see PHG Near vs With Parents or Children: What Agents Should Explain.
Which tools or sources are best for a quick PHG proximity check?
Use HDB’s official e-service for the answer that matters, and use map apps only to help clients visualise the location.
If the client is making a real purchase decision, HDB should be your first check, not your final confirmation after a map app.
A good way to think about the tools is:
| Tool | Best use | What not to use it for |
|---|---|---|
| HDB Distance Enquiry | Official PHG proximity check for a specific unit | Explaining general neighbourhood feel |
| Google Maps or similar apps | Showing landmarks, travel routes, nearby amenities | Deciding whether PHG proximity has been met |
This distinction helps client conversations. Map tools are excellent for showing that the flat is near the parents’ estate, the MRT, or a familiar shopping mall. But PHG is not based on how intuitive the location feels. It is based on the official distance check.
If you need a broad overview of PHG before the address-level check, use HDB’s PHG page or PropKaki’s main grants guide. For a broader overview, see How Much Is the Proximity Housing Grant (PHG)? Grant Amounts and What Affects It.
Why can two people get different answers from the same map search?
Because different tools may measure route distance, straight-line distance, or use different map data. That is why app screenshots are not a PHG determination.
One agent may be looking at a driving route. Another may be using a point-to-point measure. A client may even be eyeballing the map without measuring at all. Google Maps itself explains different ways of measuring routes and distances in its help guide.
The practical point is simple: when PHG affects whether a buyer will pursue the unit, rely on HDB’s distance enquiry, not a screenshot from a general map app.
Insight line: if the number changes when the app changes, it is not your PHG answer yet.
What should you confirm before telling the client they likely qualify for PHG?
Confirm the HDB distance result first, then review the broader PHG basics. A passing distance check is helpful, but it is not the same as saying the grant is confirmed.
Once the distance screen looks positive, the next step is to make sure the rest of the PHG story still fits. At minimum, confirm that:
- the purchase is for a resale HDB flat
- the relevant parent or child household is the correct one to check against
- the family’s living arrangement matches the PHG explanation you are giving
This is where agents should slow down if the setup is unusual. For example, if the buyer says they want PHG for living near parents but later mentions the parents may move again soon, that is not a detail to brush aside. It affects how confidently you should speak about the grant.
A good client-facing line is: “The unit appears to pass the distance screen. Next, we should make sure the rest of the PHG criteria line up before treating it as likely.”
For a fuller explanation, link clients to PropKaki’s PHG eligibility guide and, where relevant, the article on PHG near vs with parents or children.
When should you do the PHG check in the buying process?
Do it before the buyer makes an offer, pays the option fee, or exercises the OTP. PHG proximity should help shortlist units, not create a problem after commitment.
The best time to run the check is as soon as the buyer has a serious shortlist of actual units.
A practical agent workflow is:
- Use the buyer’s target area only for broad searching.
- Once a specific flat is shortlisted, confirm the parents’ exact residential address.
- Run the HDB distance check before the buyer commits.
- Save the result and refer to it in the follow-up conversation.
This is not just admin discipline. It changes deal quality. If you check too late, the buyer may already be emotionally anchored to the flat and start treating PHG as part of the affordability plan. That makes a negative result much harder to manage.
Sharp takeaway: PHG should filter the shortlist early, not rescue the deal later.
What should an agent verify before the client commits to a resale flat for PHG?
Use this pre-offer checklist so the client is not relying on an unverified proximity assumption.
- ✓Confirm the exact resale flat address, not just the block area or estate.
- ✓Confirm the parents’ or child’s actual residential home address.
- ✓Do not use a mailing address, outdated address, or assumed family address.
- ✓Run HDB’s Distance Enquiry for Proximity Housing Grant.
- ✓Save a screenshot or printout of the HDB result for your records.
- ✓Explain that the result is a proximity screen, not full grant approval.
- ✓Recheck the addresses if the family mentions a recent move or unusual living arrangement.
- ✓Complete this check before the offer, option fee, or OTP exercise.
If the flat is within 4km, can I tell my buyer they will definitely get PHG?
No. A flat being within 4km only addresses the proximity part of PHG. The buyer still needs to satisfy the rest of the grant framework.
You can tell the buyer the flat appears to meet the distance requirement, but do not describe the grant as guaranteed.
This is where wording matters. “Within 4km” is a useful green light for shortlisting and affordability planning, but it is not the same as final grant approval. Other eligibility points still need to make sense for that buyer and that transaction.
A safer script is: “The unit appears to pass the PHG distance check. We should still review the rest of the PHG requirements before treating the grant as likely.” If the buyer is also asking how PHG may affect their grant planning overall, you can point them to PropKaki’s guide on how much PHG is.
What should I say if the flat looks close to 4km but I have not verified it yet?
Tell the client it looks promising, but PHG should only be treated as likely after the official HDB distance check for that exact unit.
A practical client-facing reply is: “This flat looks close enough that PHG may be possible, but I need to verify it using HDB’s official distance enquiry before we treat it as eligible.”
That does three useful things at once:
- it acknowledges the buyer’s interest
- it avoids an overconfident verbal yes
- it makes the next step clear
If the buyer wants to move fast, offer to run the HDB check immediately and send them the saved result. That is usually better than debating screenshots from different apps.
Good agents do not sound vague here. They sound precise about process.
