Australians spend over $12 billion on home renovations every year. But not all renovations are created equal — some add two dollars of value for every dollar spent, while others recoup less than half their cost. Before you pick up a sledgehammer or call a builder, here's what the data says about renovation ROI in Australia.

Why Renovation ROI Varies So Much
Renovation ROI depends on three things: what you spend, what the market values, and where your property sits relative to the suburb ceiling. Spend $150,000 renovating a $600,000 home in a suburb where the median is $700,000, and you've likely capped your upside. The same money spent on a $700,000 property in a $1.1M suburb could return every dollar.
The concept of over-capitalisation — spending more on a home than the market will return — is the number one renovation mistake Australians make. Before any project, check comparable sales in your street. Your renovated home cannot consistently sell above the suburb ceiling, regardless of quality.
Renovations With the Best ROI in Australia
1. Kitchen Renovation: 80–130% ROI
The kitchen is the room that sells homes. A dated kitchen is the single biggest detractor in buyer perception, and an updated one is the biggest attractor. In Australian real estate, kitchens drive disproportionate value.
A mid-range kitchen renovation — new benchtops (stone, not laminate), updated cabinetry faces, new appliances, and modern tapware — typically costs $20,000–$45,000 and adds $30,000–$70,000 in perceived value. A full structural kitchen renovation (moving walls, relocating plumbing) runs $50,000–$100,000+ and carries more risk of over-capitalisation.
Best return kitchen strategy: Replace cabinet fronts and handles (not the carcasses), install stone benchtops, add a tile splashback, and replace the cooktop and rangehood. This "cosmetic" approach costs $15,000–$25,000 and can return $30,000–$50,000 — making it the highest ROI kitchen approach for most mid-market properties.
2. Bathroom Renovation: 70–120% ROI
Bathrooms are the second-highest ROI renovation. A full bathroom renovation (new tiles, vanity, shower, toilet, and tapware) typically costs $15,000–$35,000 and adds $20,000–$45,000. The ROI is highest on the primary bathroom — additional bathrooms and ensuites return less per dollar.
Key value drivers: floor-to-ceiling tiles (not just a dado), a frameless shower screen, a wall-hung vanity, and matt black or brushed nickel tapware. Buyers notice these details and they read as "quality" even when the underlying work is mid-range.
3. Fresh Paint and Flooring: 100–150% ROI
Consistently the highest return-per-dollar renovation. Internal repainting (neutral tones throughout) and replacing worn carpet with timber or hybrid flooring is the renovation that transforms a tired home into one that photographs well and presents beautifully.
| Project | Typical Cost (3-bed home) | Value Add | ROI |
|---|---|---|---|
| Internal repaint | $5,000–$9,000 | $10,000–$20,000 | 120–200% |
| Hybrid/timber flooring (replace carpet) | $8,000–$18,000 | $15,000–$30,000 | 100–150% |
| Both combined | $13,000–$27,000 | $25,000–$50,000 | ~130% |
4. Landscaping and Kerb Appeal: 80–150% ROI
First impressions drive buyer psychology more than any other factor. A home with a well-maintained garden, clean driveway, and fresh external paint significantly outperforms equivalent homes that are tired externally — even if the interior is identical.
Budget landscaping ($3,000–$8,000) covering lawn repair, new garden beds, a pressure-washed driveway, and fresh external paint can return 150–200% when the neighbourhood median supports it. Expensive landscaping (pools, decks, outdoor kitchens) typically returns less.
5. Adding a Bedroom: 60–100% ROI
Converting a study, garage, or large living area into a legitimate bedroom (with a window, closet, and proper access) can add significant value — particularly in markets where the price difference between a 3-bedroom and 4-bedroom home is $80,000+. Conversion costs range from $15,000 (simple room conversion) to $60,000+ (adding a structural room or garage conversion with proper insulation, wiring, and heating).
The ROI depends entirely on the price gap between bedroom counts in your suburb. Run the numbers before committing.
Renovations With Poor ROI
Swimming Pools: 30–60% ROI
A concrete in-ground pool costs $50,000–$100,000 to install. In most Australian suburbs, it adds $20,000–$50,000 in value — and carries ongoing costs of $3,000–$5,000 per year in maintenance, chemicals, electricity, and insurance. Pools are lifestyle purchases, not investment ones.
There are exceptions: in high-end Sydney and Melbourne suburbs where pools are expected, or in Queensland where the lifestyle premium is real. But as a general rule, if you're renovating to sell, don't install a pool.
Solar Panels: 50–80% ROI on Resale
Solar adds value, but not dollar-for-dollar. A $10,000 solar system typically adds $4,000–$8,000 to a property's sale price. The financial case is better made through energy savings over time — see our Solar Savings Calculator for the full payback analysis. If you're renovating to sell, solar is rarely the best use of capital.
Luxury Finishes in Mid-Market Properties: 30–60% ROI
Marble bench tops, imported Italian tiles, and high-end appliances in a $650,000 median suburb return far less than what they cost. Buyers in that market expect nice but not exceptional — and will not pay the premium for luxury finishes. Save those choices for properties where the median supports them.
The Pre-Sale vs. Lifestyle Renovation Question
If you're renovating to live in the property for 10+ years, ROI matters less. Lifetime enjoyment should drive decisions — a pool you use every summer has value that doesn't show in a valuation.
If you're renovating to sell within 2–3 years, ROI is everything. In this case:
- Focus on cosmetic projects that photograph well (paint, flooring, landscaping)
- Update kitchens and bathrooms without going structural
- Avoid large infrastructure projects (pools, extensions) unless the numbers are very clear
- Price improvements to the suburb median, not your personal taste
How to Estimate Your Renovation's ROI
- Get a pre-renovation appraisal. Ask two or three agents what the property would sell for today, and what comparable renovated properties are selling for. The gap is your upside ceiling.
- Get three builder quotes. Renovation costs vary 20–40% between builders. Get at least three detailed quotes for any project over $10,000.
- Add 20% contingency. Renovations almost always cost more than quoted. Hidden water damage, asbestos, rotten timbers — these are common in older Australian homes.
- Calculate the net ROI. (Estimated value increase − renovation cost) / renovation cost × 100. Anything above 80% is a strong result. Below 60%, question whether the project is worth it.
Run your own numbers: Our Renovation ROI Calculator lets you input costs, estimated value add, and holding period to calculate your net return.
Renovation Financing Options in Australia
Most Australians fund renovations through one of three mechanisms:
- Redrawing from an offset account or mortgage. The lowest-cost option if you have equity. Effectively borrowing at your mortgage rate (5.5–6.5%).
- Personal loan. Unsecured, faster to arrange, but higher rates (7–15%). Good for smaller projects under $30,000.
- Construction or renovation loan. Specific product for larger projects, drawn down in stages as work is completed.
Whatever the funding method, model the total cost including interest before committing. A $40,000 renovation funded by a personal loan at 10% over 5 years costs $51,000 in total — which changes the ROI calculation materially.
Frequently Asked Questions
Should I renovate before selling or sell as-is?
It depends on the state of the property. A well-presented but dated home often sells better renovated, particularly in competitive markets where buyers are searching for move-in-ready properties. However, a structurally sound home in a strong market may sell well as-is — buyers will do their own renovations. Ask your selling agent for honest advice specific to your property and suburb.
Do renovations always increase property value?
No. Poor-quality work, over-capitalisation, and renovations that don't suit the local market can fail to add value — or even reduce it. A poorly executed renovation that looks cheap, or one that creates an unusual floor plan, can be a detractor for buyers.
How do I avoid over-capitalising?
Research comparable sales for your street and suburb. Identify the ceiling price for well-renovated homes. Ensure your total spend (purchase price + renovation cost) leaves a meaningful margin below that ceiling. If your renovated property would need to sell for a record price just to break even, you're over-capitalising.
