1. Overall timeline
A standard HK residential purchase takes 45–90 days from offer to completion. Buyers with mortgage Approval-in-Principle in hand can complete in 45 days; those requiring fresh mortgage assessment or stress-testing extend to 60–90 days.
Negotiation happens in a narrow 3–14 day window before PASP signing — this is where your final price is decided.
2. The 10 steps in detail
1️⃣ Budget & mortgage AIP — obtain approval-in-principle from 2–3 banks.
2️⃣ Engage estate agent & viewings — pick 1–2 agents active in your target estate.
3️⃣ Request comparable sales — same-block and neighbouring-block transactions over the last 6 months.
4️⃣ Make a counter-offer (negotiate) — the critical window where an independent buyer-side negotiator adds most value.
5️⃣ Sign the Provisional Sales & Purchase Agreement (PASP) — typically within 24 hours of price agreement, paying an initial deposit (3–5% of price).
6️⃣ Engage solicitor — title investigation, mortgage documents, stamp duty, conveyancing.
7️⃣ Sign the formal Sales & Purchase Agreement — within 14 days of PASP, topping deposit up to 10%.
8️⃣ Formal mortgage application — bank valuation, approval, mortgage instructions to solicitor.
9️⃣ Pay stamp duty — within 30 days of PASP signing.
🔟 Completion — final payment, deed transfer, keys handover.

| Within 30 days | Stamp duty | 370,000 |
| Completion | Solicitor's fees (buyer) | 10,000 – 18,000 |
| Completion | Agent commission (1%) | 100,000 |

| Mortgage amount | 70% mortgage | 7,000,000 |
4. Common pitfalls
🚩 Under-valuation: bank valuation below agreed price → LTV compressed, buyer must top up down-payment. Always obtain a valuation quote before signing PASP.
🚩 Seller reneges: verbal agreement but pre-PASP, a higher offer arrives and the seller walks away. The only protection is signing PASP fast.
🚩 Deposit forfeiture: buyer withdraws post-PASP → forfeits 5% and may face damages.
🚩 Stamp duty cashflow: many buyers forget to reserve for the 30-day stamp-duty deadline.
🚩 Title defects: solicitor's title check uncovers issues, delaying or killing completion.
5. One-page buying playbook
If you remember one thing: a Hong Kong purchase is decided in the days before the provisional agreement is signed, not at handover. Below is the ten-step process condensed into a single checklist with realistic day counts.
Step 1 — Set the budget and get mortgage approval-in-principle (3–7 days): apply to two or three banks, confirm the loan amount, rate and stress-test outcome. Offering without pre-approval means offering without knowing your ceiling.
Step 2 — Narrow the search (7–21 days): settle on one or two estates and record aspect, noise, condition and the seller's reason for each viewing.
Step 3 — Pull comparables (1–3 days): six months of same-block and adjacent-block sales, converted to price per saleable square foot, to produce a fair range.
Step 4 — Offer and counter (1–3 days): open from the comparables with the reasoning attached, shrink each concession, and hold the ceiling you wrote down beforehand.
Step 5 — Sign the provisional agreement (same day): pay the initial deposit (typically 3%–5%) and appoint a solicitor. The price is locked at this point.
Step 6 — Formal mortgage application and valuation (7–14 days): the bank instructs a valuation; a short valuation directly reduces what you can borrow.
Step 7 — Sign the formal agreement (within 14 days of the provisional): top the deposit up to 10% and pay ad valorem stamp duty (generally within 30 days).
Step 8 — Title search and mortgage documentation (14–30 days): check title, unauthorised works and unfinished works.
Step 9 — Completion and payment of the balance (typically 45–60 days after the provisional).
Step 10 — Handover (same day): check utility readings, keys, the fixtures list and management office registration.
6. FAQ
Which step of the buying process matters most?+
Step 4, the offer and counter. There are usually only 24 to 72 hours between the first offer and the provisional agreement, and that price sets ad valorem stamp duty, agency commission and your mortgage principal. Every earlier step exists to prepare for it.
How long does buying a Hong Kong flat take end to end?+
Typically 45 to 90 days. Buyers holding a mortgage approval-in-principle can complete inside 45 days; a fresh mortgage application, a short valuation or a title issue pushes it to 90 days or more.
Can I cancel if the mortgage is short-approved?+
No. Standard PASP terms don't allow withdrawal for mortgage reasons. If your mortgage falls short, you must top up the down-payment or forfeit the 5% deposit. Always confirm the mortgage before signing.
Is the process different for primary sales?+
Yes — primary (new) sales use developer's standard contracts, with more payment plans and cash rebates but less negotiation room. This guide focuses on secondary market where discounts are meaningful.
What must I ask the agent at viewings?+
At minimum: reason for sale, days on market, seller's acquisition price, same-block sales in the last 6 months, saleable-area ratio, management fee, illegal structures, outstanding works.
