Buyers will face resale restrictions after MOP
Your block has 61 years of lease left. A buyer who purchases today and waits out their 5-year MOP will be selling a flat under 60 years — which means their buyers face CPF and loan limits. Savvy buyers know this. It shrinks your pool and puts downward pressure on price.
An experienced agent can help you find motivated buyers and close before this becomes a bigger factor.

How much cash will I actually receive when I sell my flat at Block 423?
Your gross sale proceeds are what the buyer pays. From that, three things are deducted: your outstanding loan, your CPF principal (all CPF savings used for the flat, returned to your CPF OA), and CPF accrued interest (the interest CPF calculates on those savings at 2.5% p.a., compounded annually). What remains after these deductions is your cash in hand. Use the What's Your Flat Worth? calculator above to estimate your actual cash take-home based on Block 423 prices.
What is CPF accrued interest and why does it reduce my sale proceeds?
When you buy a flat using CPF, those funds are considered a loan from your CPF OA to yourself. When you sell, CPF Board requires you to return the principal plus the interest those funds would have earned had they stayed in your OA — currently 2.5% per annum, compounded. This is not a penalty or a fee paid to anyone; the money goes back into your CPF OA. However, it does reduce your cash proceeds — and the longer you have owned the flat, the larger the accrued amount. Use the CPF Accrued Interest Calculator above to estimate your deduction before you decide to sell.
How active is the resale market at Block 423?
Block 423 has recorded 26 resale transactions — roughly 1.1 sales per month over the past 24 months. The latest transaction closed in 2026-02.
What flat types are available at Block 423?

How much can I unlock to upgrade if I sell my HDB at Block 423?
Selling to upgrade means planning both timelines and funds. Your proceeds split into cash in hand (for your next downpayment and transition costs) and CPF refund (returned to CPF OA). Use the What's Your Flat Worth? calculator above to estimate the equity you can deploy for your next home.
What is the remaining lease for Block 423?
Block 423 was built in 1988 with a 99-year lease. It has approximately 61 years 07 months remaining.
Does Block 423's remaining lease affect its resale value?
At 61 years remaining, most buyers still qualify for full CPF usage. Buyers in their late 30s or older may see slight CPF caps depending on their age, but the effect on your buyer pool is small. Pricing at market rate remains straightforward.
When can I sell my flat at Block 423 Yishun Ave 11?
Flats at Block 423 Yishun Ave 11 have cleared their 5-year Minimum Occupation Period (MOP) and are eligible for resale on the open market. You can list your flat now.
How long does it take to sell an HDB flat?
The standard HDB resale process takes approximately 8–12 weeks from granting the Option to Purchase (OTP) to the completion appointment. This includes HDB resale application, HDB valuation, CPF usage approval, and final appointment scheduling.
Can I sell my HDB flat without an agent?
Yes — HDB's resale portal allows you to handle the transaction yourself. However, for owners upgrading to their next home, an experienced agent helps align pricing, buyer negotiation, and completion timing so your next purchase is less exposed to delays. The typical 1–2% commission is often recovered through a stronger sale outcome.
What are the costs of selling an HDB flat?
Typical costs for a seller:
Agent commission ~1–2% of sale price
Legal / conveyancing ~S$500 (HDB) or ~S$2,000 (private)
