Key Takeaways

  • ✓ You must fulfil your HDB MOP (5 years standard, 10 years for PLH) before buying private
  • ✓ CPF refund (principal + 2.5% accrued interest) reduces your actual cash proceeds
  • ✓ You have 6 months to sell your HDB after purchasing a completed private property
  • ✓ ABSD of 20% applies if you hold both properties simultaneously (Singapore Citizens)
  • ✓ Bridging loans can cover the gap between your HDB sale and condo purchase
01

Check Your MOP Status

Your MOP starts from the date of key collection, not the purchase date. Standard HDB flats require 5 years. Prime Location Housing (PLH) flats introduced from 2021 onwards require 10 years. During MOP, you cannot sell your flat on the open market, rent out the entire flat, or purchase a private residential property in Singapore.

02

Calculate Your CPF Refund

When you sell your HDB, you must refund the CPF principal used plus accrued interest at 2.5% per annum back into your CPF Ordinary Account. This is not a penalty — it returns your retirement savings. However, it reduces the cash you receive. Use my free calculator to estimate your CPF refund based on your purchase price and years held.

03

Estimate Your Cash Proceeds

Cash proceeds = Sale Price – Outstanding HDB Loan – CPF Refund – Agent Commission (~1%) – Legal Fees (~$2,500–$3,500). This is the real amount you have available for your private condo purchase. Many upgraders are surprised how different this is from the headline sale price.

04

Assess Your Loan Eligibility

Private condo purchases require a bank loan, not an HDB loan. Banks apply TDSR (Total Debt Servicing Ratio) of 55% — your total monthly debt obligations cannot exceed 55% of your gross monthly income. Get an In-Principle Approval (IPA) from a bank before committing to any purchase.

05

Plan Your Timing Strategy

The sequencing of your sale and purchase matters significantly. Selling first gives you certainty on cash proceeds but may leave you without a home temporarily. Buying first requires a bridging loan and means you will pay ABSD upfront (which you can claim back after selling your HDB within 6 months). I help clients map out both scenarios with actual numbers.

Frequently Asked Questions

What is the MOP for HDB flats in Singapore?
Standard HDB flats have a 5-year MOP from key collection date. PLH flats introduced from 2021 have a 10-year MOP. You must fulfil MOP before selling your flat or buying a private residential property.
How much CPF do I need to refund when I sell my HDB?
You must refund the CPF principal used plus accrued interest at 2.5% per annum back to your CPF OA. This reduces your actual cash-in-hand from the sale.
Can I own an HDB and a private condo at the same time?
Yes, after MOP. But you must sell your HDB within 6 months of purchasing a completed private property. ABSD of 20% applies if you hold both simultaneously (Singapore Citizens).
How do I calculate my cash proceeds from selling my HDB?
Cash proceeds = Sale Price – Outstanding Loan – CPF Refund – Agent Commission – Legal Fees. The remainder is your usable cash for the condo purchase.
