Is renovating an investment property worth it?

It can be. Renovating may let you increase the rent or create equity faster, but you need to make sure the extra value you create is worth the money and time you put in.

How much should I budget to renovate an investment property?

Often property investors budget for $65,000 to $80,000, but renovation costs can go higher.

Is it better to renovate an existing property or buy a New Build?

Neither is automatically better. Renovating may suit you if you want to manufacture equity and have the money, skills and time to manage the project. A New Build may suit you if you want a more hands-off investment or want to use less money upfront.

Do I need renovation experience to renovate an investment property?

No, but you’ll probably need to pay professionals for more of the work if you don’t have the skills yourself. That means labour costs need to be included when you work out whether the renovation stacks up.

As a financial adviser one of the main questions people ask me is, “Should I renovate properties to grow my wealth? Or should I invest in New Builds?”

Renovating can be a successful investment strategy ... I’ve spoken to investors who’ve created six figures of equity from a single renovation.

But that doesn’t mean it’s the right strategy for everyone.

In this article you’ll learn the 5 questions you need to ask yourself to work out whether renovating is the right investment strategy for you.

Now just keep in mind that here at Opes Partners we generally recommend New Builds to investors.

So there is an incentive for me to tell you not to renovate properties and buy a New Build instead.

I’m not going to do that. Instead, this will be an honest analysis, where I lay out the pros, cons and trade-offs. Then I’ll take a step back so you can make the decision for yourself.

Top takeaway

Renovating can create equity faster, but it usually requires more money, skills and time than a New Build. The right strategy depends on what you’re trying to achieve and whether you’re prepared to take on the extra work and risk.

#1: What are you trying to achieve?

Don't start with: “I want to renovate.” That’s not often the goal for most investors.

Do you want to create equity now, improve your cashflow, or build a larger portfolio for long-term wealth?

Your goal	Strategy that may suit
Build a larger portfolio	A New Build may leave more money available for your next purchase
Increase cashflow now	Renovating may allow you to increase the rent
Manufacture equity now	Renovating allows you to actively add value

For example, one investor we spoke to bought a run-down Palmerston North property for around $300,000.

He spent about $110,000 renovating it and once finished it was valued at around $530,000.

That's roughly $120,000 of additional value created through the renovation.

That's the attraction: you can create equity yourself.

But a New Build strategy generally requires less money upfront. That can leave more of your deposit available to buy properties #2 and #3. That’s because New Builds are exempt from the Reserve Bank’s loan-to-value ratio restrictions.

So before you decide how you’re going to invest, decide what you’re trying to achieve first.

Is it a one-off equity hit or do you want to grow a bigger portfolio?

#2: How much money do you have?

Renovating can require a lot more money upfront.

A New Build often needs a 20% deposit
An existing investment property often needs 30%

Let’s say you want to invest in a $700,000 property. If it’s a New Build it would need at least a $140,000 deposit most of the time.

If it’s an existing property, it would typically need a $210,000 deposit.

And that’s before you’ve picked up a hammer.

A typical renovation often costs $65,000 to $80,000.

If you spend $70,000 renovating, you could need $280,000 upfront – double the $140,000 New Build deposit.

If you have	What it could mean
A smaller deposit	A New Build may be more achievable
A larger deposit + renovation budget	Renovating becomes more realistic
Enough money for an existing property, but little buffer	Be cautious – renovation costs can blow out

And the budget you start with isn’t necessarily the budget you finish with.

You might uncover rotten timber; materials might change; or the job might be delayed.

One investor we know is a quantity surveyor. His job is literally to understand what construction projects should cost.

Yet when he started renovating his own home he was hit with an unexpected $9,000 excavation bill … which he is now disputing.

That’s an extreme example, but if a quantity surveyor can get a surprise $9,000 bill, it shows how difficult renovation costs can be to predict.

With a New Build you generally know what you’re paying upfront. With a renovation, there are more opportunities for the final bill to change.

#3: Do you actually have the skills to renovate?

Renovating is an easy property strategy to picture yourself doing.

You’ve painted a bedroom. You’ve watched The Block.

So you think: “I could do that.”

But renovating a property profitably is different from making your own house look nicer.

Your experience	What it could mean
Experienced tradie/renovator	You have skills that could reduce the cost of renovation
Handy, but little renovation experience	You may be able to do some jobs, but you’ll still need professionals to help (e.g. builders)
No practical experience	Budget for a team to do the work rather than relying on DIY

And even if you genuinely have the skills, ask yourself whether you actually want to use them.

One investor we spoke to is a builder.

He planned to renovate an older house himself and save money on labour.

Five weeks in, he’d had enough.

After building all week he didn’t want to spend his evenings and weekends doing more.

Five years later, the renovation still isn’t finished.

Of course, you don’t have to do the work yourself. You can hire professionals instead, but then you need to factor labour into the numbers.

That’s one of the big differences with a passive New Build strategy. You don’t need to know how to renovate, find tradies, or work out which jobs you can safely do yourself.

#4: How much time do you have?

Renovating a house takes a lot of time.

We know that because for tradespeople renovating houses is their full-time job.

So, if you’re planning to do it yourself where are those hours going to come from?

After work? On the weekends you spend with your family?

Some investors do sacrifice family time and free time to renovate properties … others aren’t so keen. Ultimately it’s your choice.

Your situation	What it could mean
Plenty of spare time	DIY and project management may be realistic
You’ve got some evenings and weekends free	You can renovate, but expect it to take up a lot of your spare time
Busy career / young family	A hands-on renovation strategy may be difficult to sustain

Of course, you can pay someone else to do the work.

One investor we know works full-time and still renovates around two properties a year. He has a team who do most of the physical work for him.

And it works: his latest project created around $120,000 of additional value.

But having a team doesn’t make the investment passive.

His recent renovations had issues with burglary and vandalism. Over Christmas he even slept at one of the properties to deter break-ins.

He was still mowing lawns, checking on the property and dealing with problems as they came up.

That’s the trade-off.

You can outsource the building work, but you don’t necessarily outsource the headaches.

A New Build is different. It’s a much more hands-off investment. You aren’t managing trades, spending your weekends painting walls or checking on an empty renovation site.

So, if you’ve got plenty of spare time and want to be hands-on, renovating might suit you.

If you’re already juggling a full-time job, kids and everything else that comes with life, you need to ask whether you really want another job on top of that.

#5: How quickly do you want to grow your portfolio?

If your goal is to own several investment properties, don’t just ask whether this property is a good investment.

Ask: How does it help me buy the next one?

Your priority	What it could mean
Grow a larger portfolio faster	New Builds may suit because the lower upfront cost can leave more money available for your next purchase
Create equity to partially fund the next property	Renovating may suit if you can manufacture enough usable equity
Not focused on buying again quickly	Either strategy could work

This is where the money you spend on property #1 can affect how quickly you get to property #2.

A New Build may leave more of your capital available for another deposit.

For example, say you have $280,000 of usable equity available. You could use the full amount to buy a $700,000 existing property and spend $70,000 renovating it.

Or that same $280,000 could cover the 20% deposits on two $700,000 New Builds.

Of course, the bank still needs to approve the lending.

Having said that, while a renovation costs more upfront, if it’s successful it might create equity to help fund a part of the next purchase.

So, should I renovate?

Renovating can be a successful strategy if you have the money, skills and time to do it well.

If not, a more hands-off strategy may suit you better.

Renovating may suit you if	A New Build may suit you if
You want to manufacture equity now	You’re happy to build wealth over the long term
You have the money and a healthy buffer	You want to use less money upfront
You have the skills – or can pay a team	You want a more hands-off investment
You have the time to manage a project	You want to focus on growing your portfolio

But neither strategy is automatically better.

So, don’t just ask: “Could I make money renovating?”

Ask: “Is renovating the best use of my money, my skills and my time?”

If the answer is yes, pick up the hammer. If it’s not, there’s nothing wrong with leaving it in the toolbox.

Key takeaways

Renovating can help you create equity faster, rather than waiting for the market to do it.
Renovating usually needs more money upfront than a New Build, especially once you include the renovation budget.
Your skills matter. If you can’t do some of the work yourself you’ll need to budget for trades and labour.
Renovating also takes time. Even if you outsource the physical work, you may still need to manage the project and deal with problems.
A New Build may suit you better if you want a more hands-off investment or want to keep more money available for your next property.
The right strategy depends on what you’re trying to achieve with your money, skills and time.
