Your flat is approaching a key resale threshold
Your block has 70 years of lease left. Today, buyers can still get full CPF and bank loans — no restrictions. But once the lease drops below 65 years, buyers who purchase now will struggle to resell after their MOP. The closer you get, the smaller your buyer pool becomes.
An agent who knows this block can position your flat now, before the window narrows.

What is my flat worth at Block 173?

How much cash will I actually receive when I sell my flat at Block 173?
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 173 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 173?
Block 173 has recorded 18 resale transactions — roughly 0.8 sales per month over the past 24 months. The latest transaction closed in 2026-01.

How much can I unlock to upgrade if I sell my HDB at Block 173?
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 173?
Block 173 was built in 1997 with a 99-year lease. It has approximately 70 years 11 months remaining.
Does Block 173's remaining lease affect its resale value?

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.
