The Three MOP Tiers
| Flat Classification | MOP Duration | Notes |
|---|---|---|
| Standard | 5 years | Same as historical MOP for most resale and pre-October 2024 BTO flats |
| Plus | 10 years | Good locations, received additional subsidies |
| Prime | 10 years | Best locations (city fringe, mature estates), highest subsidies |
| Fresh Start Housing Scheme | 20 years | Second-time buyers receiving higher grants |

How MOP Is Calculated
MOP starts from the date of legal completion of purchase — not the booking date, not the key collection date.
For resale flat purchases: MOP begins on the date of resale completion registered with HDB.
The clock pauses if:
- The flat is entirely rented out (with HDB approval) during MOP — those rental months do not count toward MOP.
- A lease infringement occurred.
All flat owners, essential occupiers, and spouses listed on the flat must physically reside in the flat throughout MOP.
What Cannot Be Done During MOP
Regardless of flat tier, flat owners cannot:
- Sell the flat on the open market
- Rent out the entire flat (renting individual rooms is allowed for Standard flats, subject to HDB eligibility criteria)
- Purchase any private residential property — including overseas property
The overseas property restriction catches clients off-guard. Ownership of a condo in Kuala Lumpur or Melbourne during HDB MOP is not permitted.
After MOP — Standard Flats vs. Plus/Prime Flats
Standard flats after 5-year MOP:
- Can sell on the open market
- Can rent out the entire flat (with HDB approval)
- Can purchase private residential property (ABSD applies)
Plus and Prime flats after 10-year MOP:
- Can sell on the open market — but only to Singapore Citizens or PRs
- Cannot rent out the entire flat (ever) — this restriction is permanent, not lifted by MOP. Room-by-room rental of spare bedrooms (3-room and larger, with HDB approval) remains permitted. Source: HDB Standard, Plus and Prime Housing Models.
- Subject to subsidy clawback: HDB recovers a percentage of the higher of resale price or valuation upon sale
- Can purchase private residential property (ABSD applies)
The subsidy clawback on Plus/Prime flats is a significant factor in the net sale proceeds calculation. Advise clients to check the clawback percentage for their specific project before making resale decisions.
CEA Compliance Note for Agents
CEA has specifically flagged MOP advice as a compliance risk area. Agents must not advise clients on structuring around MOP rules — for example, suggesting nominee arrangements or informal property ownership transfers during MOP. Such advice may expose agents to CEA disciplinary action.
Practical Questions Agents Handle
“My client bought a resale HDB in 2022 — when can they sell?”
Standard resale flat: 5-year MOP from completion date. Earliest sale: 2027.
“Does the client own a resale flat from 2020 and want to buy a private condo now?”
If their MOP is not yet complete (2025): they cannot own private residential property. They would need to wait until MOP is complete before purchasing.
“My client bought a Plus flat in the October 2024 BTO — when is their MOP?”
10-year MOP from legal completion (likely 2028–2030 depending on project). Earliest sale: approximately 2038–2040. The subsidy clawback applies upon sale.
