Renovate Your Home or Pay Down Your Mortgage?

Key Takeaways

  • 1Some renovations can lower your LVR, potentially unlocking better interest rates.
  • 2Direct mortgage payments guarantee debt reduction while renovations offer uncertain returns.
  • 3Prioritize mortgage reduction early and save renovations for closer to sale date.
  • 4Align renovation choices with buyer appeal rather than personal preferences.

Should NZ homeowners prioritize home renovations or mortgage reduction? Here are the key considerations.

It's a common dilemma for homeowners with extra cash: should you put that money into renovating your home or paying down your mortgage? Both options have merit, but the right answer depends on your specific situation, timeline, and priorities.

The Case for Paying Down Your Mortgage

Putting extra money toward your mortgage offers several guaranteed benefits:

Guaranteed Returns

Every dollar you pay off your mortgage saves you interest at your current mortgage rate. If you're paying 6.5% interest, an extra $10,000 payment effectively earns you a guaranteed 6.5% return-tax-free. No investment offers guaranteed returns like this.

Interest Savings Example:

Extra PaymentInterest RateAnnual Saving10-Year Saving
$10,0006.5%$650$6,500+
$25,0006.5%$1,625$16,250+
$50,0006.5%$3,250$32,500+

These savings compound over time. Pay off an extra $50,000 early in your mortgage, and you could save over $100,000 in total interest over a 25-year term.

LVR Improvements

If you're near an LVR threshold (especially 80%), paying down your mortgage could unlock better interest rates. Crossing from 81% to 79% LVR might save you 0.5-1.0% on your interest rate-potentially thousands of dollars per year.

Reduced Financial Risk

A lower mortgage means lower required payments, giving you more breathing room if your income drops or expenses increase unexpectedly.

The Case for Renovating

Renovations offer potential returns that mortgage payments can't:

Capital Appreciation

The right renovations can increase your property's value by more than what you spend. This creates wealth that you can access through selling or refinancing.

Lifestyle Benefits

A nicer home improves your daily life. You can't put a dollar value on enjoying your space more, having a functional kitchen, or not cringing every time you see that dated bathroom.

Potential to Lower LVR

If renovations increase your property value significantly, they could lower your LVR just as effectively as paying down the mortgage-while also giving you a better home to live in.

Which Renovations Actually Add Value?

Not all renovations create equal returns. Here's what the research shows:

High-return renovations include kitchen updates with new cabinetry, benchtops, and appliances (often returning 60-80% of cost), bathroom refreshes (returning 50-70% of cost), improved street appeal through front door upgrades, landscaping, and painting (high visual impact, moderate cost), and adding living space by converting a garage or adding a bedroom (though returns vary widely).

Low-return renovations include swimming pools (which rarely recoup costs and can even reduce your buyer pool), highly personalised finishes (your taste may not match buyers' preferences), over-capitalisation (spending more than the neighbourhood supports), and structural work without visible improvement (necessary but doesn't add perceived value).

Break-even renovations include essential maintenance like roof repairs, rewiring, and replumbing (necessary but rarely adds value-just prevents loss) and Healthy Homes compliance (required for rentals but adds minimal value to owner-occupied homes).

The Timing Factor

When you plan to sell significantly affects the right choice:

Planning to Sell Within 2-3 Years:

Renovations make more sense. Fresh updates appeal to buyers, and you'll benefit from the increased sale price soon. Focus on high-impact, visually obvious improvements.

Planning to Stay 5+ Years:

Mortgage reduction often wins. The interest savings compound over time, and renovations you do now may look dated by the time you sell. The exception is renovations that dramatically improve your daily enjoyment.

Planning to Stay 10+ Years:

Prioritise mortgage paydown early. Once you've built significant equity and reduced your debt, you can consider renovations for lifestyle reasons rather than return on investment.

The Hybrid Approach

You don't have to choose one or the other. Many homeowners find the best approach combines both strategies. For example, in the first five years you might focus on mortgage reduction and aim to get below 80% LVR. During the middle years, balance between mortgage payments and necessary maintenance. Then before selling, do targeted renovations for maximum buyer appeal.

This approach minimises interest costs early while still allowing for improvements when they'll have the most impact on sale price.

What About Refinancing for Renovations?

Some homeowners consider increasing their mortgage to fund renovations. This can make sense if the renovation will increase property value by more than the loan amount, you're already at a low LVR with room to borrow, current interest rates are favourable, and you have a clear plan to pay down the additional debt.

However, be cautious about adding debt for purely lifestyle renovations, extending your mortgage term significantly, over-capitalising for your neighbourhood, and using your home as an ATM for repeated borrowing.

Making Your Decision

Consider these questions:

1What's your current LVR? If you're above 80%, mortgage paydown may unlock better rates.
2How long until you sell? Renovations closer to sale date maximise impact.
3Are there any urgent repairs? Maintenance should come before cosmetic upgrades.
4What's your risk tolerance? Mortgage paydown is guaranteed; renovation returns are uncertain.
5What would improve your daily life most? Sometimes the answer isn't purely financial.

Finding Your Balance

There's no universal right answer. Mortgage paydown offers guaranteed, compounding returns and reduced financial risk. Renovations offer potential capital gains and lifestyle improvements.

For most homeowners, a balanced approach works best: prioritise mortgage reduction early in your ownership, maintain your property throughout, and save strategic renovations for when you're closer to selling-or when the lifestyle improvement justifies the uncertain financial return.

Whatever you decide, make sure it aligns with your overall financial goals and timeline. A mortgage adviser can help you model different scenarios and understand how each choice affects your overall position.
