What renovation actually costs in Bali, how long it really takes, and the climate-driven expenses that catch buyers out. Plus the honest comparison against buying finished.
Renovation is the route many buyers consider first: acquire something cheaper, improve it, capture the difference. It works, and it works less often than people expect, usually for reasons that were knowable in advance. Here is what the work actually costs, how long it genuinely takes, and when buying finished is the better arithmetic. ## What renovation costs Budgets in Bali sort into three broad tiers, and confusion between them is where most overruns start. **Cosmetic work — roughly USD 15,000 to USD 40,000.** Repainting, refinishing timber, replacing soft furnishings, updating light fittings, resurfacing a pool. No structural change, no reconfiguration of services. This tier is predictable, and it is the only one that reliably comes in near budget. **Mid-range — roughly USD 50,000 to USD 80,000.** One or two major systems addressed properly: a full kitchen rebuild, complete bathroom gut-renovations, pool tiling with new plant and equipment. This is where most serious renovations land, and where the first surprises appear, because opening up one system usually reveals the condition of another. **Full structural — USD 105,000 to USD 200,000 and upward.** Reconfiguring layouts, replacing roofing, rewiring, re-plumbing, addressing foundations or drainage. At this level you are close to the economics of building new, without the advantages of building new. The tiers are not a smooth continuum. Projects tend to jump from one to the next rather than drift, because the trigger is almost always discovery rather than ambition. ## How long it really takes Cosmetic work runs four to eight weeks. Mid-range renovations take four to eight months. Full structural projects run eight to eighteen months, and the upper end of that range is more common than the lower. Three factors drive the variance, and none of them are the builder's competence. **Permits.** Any change to structure, footprint or use requires approval, and the timeline is not within your control. Buyers who assume permitting runs in parallel with mobilisation frequently lose a quarter before work begins. **The wet season.** Roughly November to March, external work slows and some of it stops. Concrete curing, roofing, rendering and landscaping all become unreliable. A project scheduled without accounting for this loses months, and a project that starts in October is usually a project that finishes in the middle of the following year. **Materials and specialist trades.** Standard materials are readily available and inexpensive. Anything imported, and anything requiring a specialist — proper waterproofing, quality joinery, imported sanitaryware, pool engineering — introduces lead times that are difficult to compress. ## The costs the climate imposes This is the category that most consistently breaks budgets, because it does not appear in any quotation. Humidity and salt air are relentless on buildings. Untreated timber moves and splits. Metal fixings corrode, including inside walls where you will not see it until something fails. Electrical work suffers from moisture ingress. Pool equipment has a shorter working life here than in a temperate climate. Drainage deserves separate mention. It is close to impossible to assess a property's drainage during the dry season, and it is the single most expensive thing to correct retrospectively. A villa that looks immaculate in August can be a serious problem in January. Two practical rules. Budget 15–20% contingency on any project above the cosmetic tier — not as pessimism, but because opening walls in this climate reveals things. And specify marine-grade fixings and proper waterproofing even where it seems excessive; the alternative is doing the same work twice. ## The comparison nobody runs properly Renovation makes sense when three conditions hold together: the acquisition price genuinely reflects the property's condition, the structure and services are sound, and you have the time and presence to manage the work. That last condition is the one people underestimate. Renovation in Bali is not a remote-management exercise. Projects run by owners who visit quarterly cost more, take longer, and finish to a lower standard than projects with someone present and accountable. If you are not going to be here, factor the cost of a project manager who will be — and factor it honestly. Run against that, buying finished trades a higher entry price for fixed cost, a contractual timeline, and immediate income. The Cemagi Collection villas are listed at **USD 345,000 (IDR 6,130,000,000)** each, sold fully furnished, with roughly 185m² of build on plots of about 250m² and a handover estimated for **Q2 2027**. The comparison is not really price against price. It is a known number against a range, and a known date against an estimate. ## The honest position Renovation genuinely can produce a better outcome per dollar, particularly for buyers who are here, who have done this before, and who bought well. For buyers who are managing from abroad, working to a defined budget, or who need the asset earning within a predictable timeframe, the arithmetic usually favours buying finished — and the buyers who regret that choice are considerably rarer than the buyers who regret the other one. Whichever route you take, the diligence that matters most is the same: the lease term and its extension mechanism, the zoning, the drainage, and the condition of what you cannot see.
