Renovation Budget Planning: Your Key Step in Singapore's Complete Buying Process
Renovation budget planning is essential in Singapore's property buying process, especially for HDB flats where costs can range from S$30,000 for a basic 3-room BTO to over S$90,000 for a 5-room resale unit.[3] This cluster article from Homejourney breaks down actionable steps to integrate budgeting into your buying journey, ensuring you avoid overruns while prioritizing safety and trust. As part of our pillar on the Complete Singapore Property Buying Process Guide, it equips first-time buyers and investors with precise 2026 estimates.
Why Renovation Budgeting Matters in the Buying Timeline
After securing your HDB flat via BTO or resale, renovation follows key milestones like CPF usage approval and loan finalization. Budgeting prevents delays under HDB's 3-month renovation permit rule and Total Debt Servicing Ratio (TDSR) limits. For resale flats, factor in higher costs due to hacking—up to S$80,400 for a 5-room extensive reno.[1] Homejourney verifies contractor data through our trusted network, helping you build a safe transaction environment.
Current 2026 market trends show material costs rising 5-10% from inflation, per industry reports.[1][2] Start budgeting post-option fee to align with stamp duties like Additional Buyer's Stamp Duty (ABSD) for investors.
Step-by-Step Renovation Budget Planning Process
Follow this tactical framework during your buying process:
- Assess Property Condition: For BTO, expect S$40,000-S$60,000 for 4-room; resale adds S$15,000+ for demolition.[1][5]
- Define Scope: Light (paint/tiles: S$15,000-S$30,000), moderate (carpentry: S$40,000-S$60,000), extensive (full overhaul: S$70,000+).[2]
- Get Quotes: Use Homejourney's Projects Directory ">projects directory for verified pros; aim for 3 quotes.
- Allocate Budget: 10-15% contingency for surprises like plumbing.[2]
- Secure Financing: Check Bank Rates ">bank rates for renovation loans up to 6% interest.
Singapore HDB-Specific Rules
HDB requires False Ceiling Permits and neighbour notifications. CPF can fund up to your Ordinary Account savings post-MSR (Monthly Servicing Ratio) checks. Foreign buyers face 60% ABSD but can renovate private condos freely under URA guidelines.
