Five years ago you signed on the dotted line. Now your MOP is up, your neighbour just sold for S$180,000 more than they paid, and everyone — your parents, your colleagues, your uncle at CNY — has an opinion on what you should do next. This guide cuts through the noise.
What is the HDB MOP?
The Minimum Occupation Period (MOP) is the compulsory period during which you must physically occupy your HDB flat before you're allowed to sell it on the open market or rent out the entire unit. It's one of HDB's core mechanisms to keep flats as homes rather than investment vehicles.
MOP by flat type
- BTO / SBF flat5 years from date of key collection
- Resale HDB flat5 years from date of resale completion
- Design, Build & Sell Scheme (DBSS)5 years from date of key collection
- Prime Location Public Housing (PLH)10 years from date of key collection
How to Check Your MOP Date
Your MOP completion date is listed on your HDB flat's records. The quickest way to check:
- 1Log in to the HDB MyFlat Portal at my.hdb.gov.sg using your Singpass
- 2Go to My Flat → Purchased Flat → Flat Details

How to Calculate Your Net Sale Proceeds
Before you get excited about the headline price your neighbour achieved, run this quick calculation to find out what you'll actually walk away with.
Note: CPF refund goes back into your CPF Ordinary Account, not your bank account. It can be used for your next property purchase, but you cannot withdraw it as cash unless you're above 55.
Real Example: 4-Room BTO in Punggol
Marcus and Priya bought their 4-room BTO in Punggol in 2021 for S$380,000. Their MOP ended in early 2026 and they want to sell.
Figures are illustrative. Actual CPF accrued interest depends on your drawdown history. Use HDB's My Flat portal for your exact numbers.
Upgrade Options by Flat Type
Where you can realistically upgrade to depends on how much equity you've built. Here's a rough guide — your actual position depends on your specific flat, town, and loan balance.
| Flat type | Typical equity range | Realistic upgrade options |
|---|---|---|
| 3-room (60–65 sqm) | S$80k–S$180k | 4-room resale, small condo in OCR |
| 4-room (85–95 sqm) | S$120k–S$280k | 5-room resale, condo in OCR/RCR |
| 5-room / EA (110–145 sqm) | S$200k–S$400k+ | Executive condo, condo in CCR |
OCR = Outside Central Region. RCR = Rest of Central Region. CCR = Core Central Region. EC eligibility requires household income ≤ S$16,000 (as of 2026).
Frequently Asked Questions
Can I rent out my whole HDB flat before MOP?
No. You cannot rent out the entire flat during the MOP period. You can rent out individual rooms — but you must continue to physically reside in the flat. Subletting the whole flat before MOP is a serious infringement and HDB can compulsorily acquire your flat.
What happens if I sell before MOP?
You cannot sell your HDB flat on the open market before completing MOP. The only exception is if HDB approves a disposal under exceptional hardship circumstances — this is rare and discretionary. Attempting to sell before MOP is illegal.
Does MOP reset if I do major renovations?
No. Renovations, even major structural ones, do not reset or extend your MOP. The MOP clock runs from the date you collect your keys (for BTO/SBF) or the date of completion (for resale flats).
Can I buy a private property before selling my HDB?
Yes, but you will pay ABSD of 20% on the private property purchase price (for Singapore citizens buying a second property). You must sell your HDB within 6 months of the private property's TOP or the date of issue of the Certificate of Statutory Completion (CSC), whichever is earlier. Failure to do so means you forfeit the ABSD remission and owe the full amount plus interest.
