Renovating an Old Condo vs Buying a New Launch in Singapore: The Real Cost Comparison (2026)

ARTICLE BODY

Here's the conversation I have with almost every resale condo buyer.

They've found the unit. Great location. Generous layout. A price $150,000 below the new launch three streets away. The previous owner's renovation is dated — tiled kitchen from 2003, a bathroom that's seen better decades — but how expensive can a refresh really be?

Then the contractor walkthrough happens. The electrician flags the wiring as undersized for a modern household. The plumber finds galvanised pipes that need full replacement. The waterproofing in both bathrooms is compromised. Suddenly the $150,000 "discount" is being rapidly consumed by works that haven't produced a single square foot of new flooring yet.

This is not a scare story. It is the renovation reality that most buyers only discover after they've committed. This guide puts the actual numbers on the table — so you can make the buy vs renovate decision with full information, not showflat optimism.

Why Old Condos Cost More to Renovate Than Most Buyers Expect

The sticker price of a renovation — the number an ID firm shows you in a beautifully formatted proposal — is typically the cosmetic layer: flooring, carpentry, painting, kitchen cabinets, feature walls.

What it frequently excludes, until the contractor starts opening up walls, is the infrastructure layer: the electrical wiring, the plumbing, the waterproofing, and sometimes the sub-floor condition. For condos built before 2005, this infrastructure layer is where the real cost surprises hide.

Resale properties typically cost 20–30% more to renovate than newer builds because of hidden works including rewiring and waterproofing. For older condos — those built in the 1990s or early 2000s — that premium can climb higher still, depending on what the inspection reveals.

Here is what the infrastructure layer actually costs in 2026:

Electrical Rewiring

Old condos often have limited power points and outdated wiring. Full rewiring ensures safety and supports modern appliances, and costs $5,000–$12,000. This is not optional for a condo over 20 years old — the wiring was designed for a household with far fewer appliances and devices than a modern family runs.

Full Plumbing Replacement

Plumbing replacement including installing bathroom and kitchen fixtures costs $5,000–$15,000 per bathroom for a full overhaul. For a 3-bedroom condo with 2 bathrooms and a kitchen, plumbing work alone can reach $25,000–$40,000 if galvanised pipes need full replacement throughout.

Waterproofing

Pipe replacement cost ranges $2,500–$8,000 depending on scope, and pipes should be replaced during renovation to avoid hacking finished tiles later. Waterproofing membranes in bathrooms and wet areas also fail over time — and when they do, the repair is not a surface fix. The tiles come up, the membrane is reapplied, and the tiles go back down. Budget $3,000–$6,000 per bathroom for waterproofing done properly.

Hacking and Debris Removal

Removal of old flooring, tiles, false ceilings, and non-structural walls costs $8,000–$15,000 depending on area size, and MCST must approve hacking plans. This is money spent before a single new fixture has been installed.

The Full Cost Breakdown: Renovating a Resale Condo in 2026

The rule of thumb for a full resale condo renovation in Singapore is $70–$120 per square foot. For a typical 3-bedroom condo of 1,000–1,200 sqft, here is what a realistic full renovation budget looks like:

For a full renovation of a 3-bedroom condo, the range is $60,000–$120,000 for standard scope, rising to $150,000–$250,000 for luxury finishes. Once you add infrastructure work for a pre-2005 unit, the realistic mid-range for a complete transformation is $100,000–$150,000.

That is money you pay in addition to the purchase price — in cash or via a renovation loan — within the first 12 months of ownership.

What a New Launch Condo Costs to "Renovate"

Now let's look at the same exercise for a new launch condo.

A new launch unit in Singapore is delivered with standard developer finishes: tiled bathrooms, kitchen cabinets, wardrobes in the bedrooms, air-conditioning, and appliances. The electrical wiring is new. The plumbing is new. The waterproofing was just done. Everything works.

New condo units can actually be cheaper to renovate as they often come with well-done fittings such as flooring, kitchen cabinets, functional bathrooms, and even wardrobes.

For most buyers, moving into a new launch requires only:

Even buyers who want to fully customise a new launch — ripping out developer finishes to install premium stone, bespoke carpentry, and custom kitchen — typically spend $60,000–$100,000 to achieve a luxury outcome in a unit where the infrastructure is already pristine.

The new launch "renovation" budget is therefore:

• $30,000–$70,000 lower than a comparable resale renovation for standard scope
• $50,000–$100,000 lower once infrastructure replacement in an old resale unit is accounted for

The True Cost Comparison: Old Resale + Renovation vs New Launch

This is the calculation most buyers never do explicitly. Let's do it now.

Scenario: Comparing a $1.5M resale condo (built 2000) vs a $1.7M new launch in the same district

The true cost gap between old resale and new launch is $130,000 — not $200,000 as the headline prices suggest. Once full renovation costs are factored in, the resale condo is still cheaper in total committed spend — but the margin shrinks considerably.

More importantly, the resale option commits you to a 74-year lease, while the new launch gives you a fresh 99-year clock. Over a 20-year hold with a resale exit in mind, this lease difference matters significantly for CPF usage rules, bank valuation, and your eventual buyer pool. (For a deeper look at why this matters, see How Lease Decay Erodes Your Property Value.)

When Renovating an Old Condo Makes Sense

Renovating a resale condo is the right move when:

1. Location is non-negotiable and the new launch equivalent doesn't exist Certain mature estates — Buona Vista, Novena, Toa Payoh, Bishan — simply don't have new launch supply. If you need to be in a specific catchment zone for schools, near ageing parents, or in a neighbourhood that new developments haven't reached, resale is your only option. The renovation cost is the price of admission to that location.

2. You need to move in quickly A new launch requires 3–4 years before TOP. If you have an immediate housing need — HDB lease expiry, growing family, current lease ending — a resale condo lets you move within 3–4 months of purchase. The renovation budget is also the price of speed.

3. You can negotiate the purchase price to absorb renovation costs A dated resale condo gives you significant negotiating leverage. A seller who hasn't renovated in 15 years knows they are competing against fresh units. If you can negotiate $150,000–$200,000 below transacted comps, and your renovation budget is $100,000–$120,000, you still come out ahead on total committed spend — and you have a personalised home rather than developer-standard finishes.

4. Layout and size matter more to you than newness Older condo developments — particularly those built in the 1990s — often have layouts and unit sizes that newer developments can't match at the same price point. A 1,400 sqft 3-bedder from 1998 in a good location will frequently offer more liveable space than a 1,000 sqft 3-bedder in a 2024 launch at the same quantum.

When Buying New Launch Makes More Sense

A new launch is the better financial decision when:

1. You plan to hold for the long term and want a clean 99-year lease clock If your goal is to hold for 15–20 years and then sell at or near the peak of the lease premium window, a new launch in 2026 gives you a lease that will still be in the 75–80 year range at exit — the sweet spot for maximum buyer pool and CPF eligibility.

2. Your renovation budget is limited If you have $40,000 available for renovation but your dream resale condo needs $120,000 in work, the mismatch will result in either a half-finished home or financial overextension. A new launch with developer finishes is move-in ready within that budget.

3. You want a guaranteed product and no renovation stress There is no MCST permit negotiation, no contractor management, no three-month construction noise, and no living out of a hotel while work is done. A new launch delivers a quality-controlled, developer-warranty-backed product. For buyers who have neither the time nor the appetite for renovation management, this is a meaningful quality-of-life difference.

4. The price gap vs resale is narrow (under $100,000) When a new launch in a comparable location is less than $100,000 more expensive than a resale unit in similar condition, the renovation cost math typically favours the new launch once you model the full outgoings.

What to Check Before You Commit to a Resale Renovation

If you decide the resale route is right for you, these are the pre-commitment checks that prevent the worst cost surprises:

Get a professional inspection first ($500–$1,200) A professional inspection can detect structural cracks hidden behind false ceilings, test for water seepage using moisture meters, and provide a defect report you can use to negotiate with sellers — potentially preventing $20,000–$50,000 in renovation overruns. This is the best $1,000 you will spend in the entire transaction.

Check the electrical distribution board A condo with a single-phase, 40-amp board was designed for a 1990s household. A modern family with EVs, induction hobs, washer-dryers, and multi-zone aircon needs a three-phase system. Upgrading the DB adds $3,000–$8,000 to your budget — but it is far better to know this before you buy.

Inspect the waterproofing in all wet areas Run the tap and look at the ceiling of the unit below. Ask the seller directly whether there have been any inter-floor leakage complaints. (For more on how to navigate leakage disputes, see Inter-Floor Leakage in Singapore: Your Legal Rights.)

Review the MCST's sinking fund and maintenance records A well-run condo with a healthy sinking fund is one where major common property repairs — lifts, pools, façade — are properly budgeted. A condo with a depleted sinking fund may face special levies in the years after you buy. Request the last 3 years of MCST AGM minutes before committing.

Get itemised quotes, not lump-sum packages Always request line-by-line breakdowns from at least three contractors or ID firms. A lump-sum "full renovation package" at $80,000 may exclude all infrastructure works. When you see itemised quotes, compare the electrical, plumbing, and waterproofing line items specifically — this is where the real variance between firms lies.

The MCST Renovation Permit: What You Actually Need to Know

Every condo renovation in Singapore requires approval from your Management Corporation Strata Title (MCST) before work begins. The process is straightforward but time-sensitive — plan for it before you set a move-in date.

What always requires MCST approval:

• Any hacking of walls or flooring
• Electrical modifications (new points, DB upgrade)
• Plumbing works
• Installation of air-conditioning units
• Changes to windows or grilles
• Any works affecting the external facade

The deposit: Most condos require a renovation deposit of $500–$2,000, held against potential damage to common areas. This is refunded after renovation completion and inspection.

Work hours: Most condos only permit renovation works from 9am to 5pm on weekdays, which leads to higher manpower costs due to lower efficiency. Weekend and evening work is typically prohibited. Factor the 9am–5pm constraint into your contractor's timeline and cost estimate.

What requires PE certification: Hacking of load-bearing walls requires a Professional Engineer's stamp — typically $500–$1,000 for the certification itself. For structural changes or canopy installations, BCA and potentially SCDF approvals add further cost and timeline.

James's Note: The MCST approval process is one of the most underestimated sources of renovation delay. I've seen clients lose a month of timeline because their contractor submitted incomplete documentation. If you are buying a resale condo with a renovation plan, build a 4–6 week buffer between key collection and your intended start date — for permit processing, deposit clearing, and contractor mobilisation.

The Honest Bottom Line

Renovating an old condo and buying a new launch are not as far apart financially as they appear on the surface — once you account for the full cost of bringing an older unit up to a liveable standard.

For a pre-2005 condo needing full renovation, the true total committed spend (purchase + BSD + renovation) is typically $100,000–$150,000 less than a comparable new launch — not $200,000–$300,000 as the headline price gap suggests.

Whether that gap is worth the trade-offs — shorter lease, renovation stress, delayed move-in, infrastructure risk — depends entirely on your priorities, timeline, and financial position. Neither answer is universally correct.

What is universally true is this: the buyers who make the best decision are the ones who model the total cost of both options before falling in love with either.
