Sub-Sale House Renovation Checklist (Klang Valley Edition)
The full pre-purchase and pre-renovation checklist for sub-sale houses in the Klang Valley — what to inspect, what to ask, what to budget.
By Aisyah Rahman
If you’re buying sub-sale in the Klang Valley, the work starts the moment you start viewing — not the moment you collect keys. Use this checklist from first viewing through to demolition day.
Stage 1 — Before you sign anything
- Get the original developer floor plan from the seller
- Pay for an independent property inspection (RM800–RM1,500)
- Check water pressure on the upper floor at peak hours
- Test every electrical socket (cheap socket tester from Shopee, RM15)
- Run all aircon units for 30+ minutes and check the drain
- Open every cabinet, every drawer, every tap
- Check ceiling for water staining
- Walk the rear yard for ponding
- Confirm whether the property has any unauthorised extensions
- Search SSM / land registry to confirm seller’s standing
Stage 2 — Between OTP and SPA
- Get strata title / individual title status confirmed
- Confirm the developer DLP is fully expired (or not transferable)
- If condo: get the JMB house rules and renovation policy
- Brief 2–3 contractors and start collecting itemised quotes
- Begin design work — don’t wait for keys
Stage 3 — Pre-renovation budget
| Cost item | Typical range |
|---|---|
| Independent inspection | RM800–RM1,500 |
| Legal + stamp duty | 3–4% of property price |
| Loan-related insurance | varies |
| Renovation contingency fund | 10–15% of renovation budget |
| Move-in / temporary storage | RM3k–RM8k |
Stage 4 — On key collection day
- Take time-stamped photos of every room
- Note every defect for your renovation contractor (separate from any developer DLP claim)
- Test every electrical and plumbing point one more time
- Confirm meter readings (TNB, Air Selangor, IWK)
- Get utility accounts transferred immediately
Stage 5 — Renovation start
- Final design approved in writing
- Contract signed with payment schedule
- Variation order template agreed
- Start photo log and weekly site visits
- Set up a shared folder for receipts and approvals
The cheapest sub-sale renovation is the one where nothing surprises you. Surprises are almost always caused by skipping Stage 1.
Things people ask us
01Do I really need an independent inspector for a sub-sale property?+
Yes. Spending RM800–RM1,500 on a proper inspection before signing the SPA can reveal RM30k–RM80k of hidden defects. The seller's word and the agent's enthusiasm are not inspections.
02When should I start renovation planning?+
The day you sign the OTP. Use the 90 days before key collection to finalise design, select your contractor, and submit any structural drawings to the local authority. Don't wait for keys.
03What's the most overlooked sub-sale defect?+
Aged wiring. Many 12+ year old Klang Valley homes still have 15A+15A consumer units that can't safely handle modern loads (induction cooktop + AC + EV charger + water heater simultaneously). A full rewire is RM8k–RM18k — it's cheaper than a fire.
