Successful Property Investment
Is your equity working? Is your bank working for you?
The difference between a smart investment and a long-term regret often comes down to one thing: your strategy. With a merely average plan, it's easy to buy an average property at the wrong time, leaving you stressed and topping up the mortgage.
Successful investors are selective. They assess deals with a proven framework and understand the cost of emotion and the price of inaction. We know, because we help them do it every day. Our advice is based on what's working in the market right now, not years ago.
Before you throw your equity at the next 'maybe' deal, let's talk. Be picky. Be strategic. And end with an offer that wins :)
They say knowledge = power, but when it comes to your property investment, knowledge = wealth.

New Build from Developer
20% of property value required. At the NZ average price of ~$900,000, that's roughly $180,000.
-
Existing Property
30% of property value required. At the NZ average price of ~$900,000, that's roughly $270,000.

Where Does the Deposit Come From?
Your deposit for an investment property can come from several sources: equity in your home (the most common way investors fund deposits without cash savings), cash savings, gifted funds from family members (lenders require documentation), or equity in other investment properties through cross-securitisation.
Using Equity in Your Home
Equity is the value of your home less your mortgage — the amount you'd receive if you sold and paid off the mortgage. If you have enough equity, lenders may allow you to borrow against it to finance your deposit.
You'll usually need to leave 20% equity in your home, but you may be able to borrow against the rest. We call anything above 20% in your main home 'usable equity', while anything above 30% equity in an investment property is generally usable.
Usable Equity = Total Equity − 20% of Home Value
For example, if your main home is worth $1.2 million with a $700,000 mortgage, that's $500,000 equity in total. You'd need to leave 20% ($240,000) in the home, but you could use the rest — $260,000 in usable equity. That's almost enough for a 30% deposit on a $900,000 home and enough for a 20% deposit on a $1.3 million new build.
To unlock this equity you'll need to speak to a mortgage broker or lender who'll assess your financial position and serviceability, then look at increasing your mortgage to provide cash for your deposit.
Equity is the reason property investment is so accessible for many older New Zealanders. Many Kiwis have owned their home for years or even decades, and through paying off the mortgage or value increases, their equity has grown — some don't even know they have a deposit ready to go.
Buying with a Smaller Deposit
The Reserve Bank sets rules around how much deposit investors must have. A 30% deposit is required for existing homes and 20% for new builds from a developer. However, 5% of every bank's lending can be to borrowers with less than the required deposit.
The trick is finding the banks who have room in their quota and convincing them to lend to you. The mortgage advisors at Blueprint Finance have strong relationships with most lenders and can advise which bank is most likely to offer low-LVR lending at any given time.
Non-Bank Lenders
Non-bank lenders are financial institutions that aren't registered banks — they can't take deposits or offer transaction accounts, but they're legitimate businesses subject to similar legislation. Because they aren't governed by the Reserve Bank's LVR rules, they may be more willing to lend to borrowers with smaller deposits.
If the banks say no, non-bank lenders are worth considering — just keep in mind that you may be charged higher interest rates and fees.
The Bank of Mum and Dad
If you don't have enough equity or cash for your deposit, you may still be able to invest. If your parents own their own home, you may be able to use equity from their property to put together your deposit.
This works the same as topping up your own mortgage to access equity. We've seen some parents gift equity, but typically both parties create an agreement about how the money is repaid — often by repaying the topped-up section of the mortgage.
Understanding Investment Property Finance
-
LVR Requirements
New builds: up to 80% LVR (20% deposit). Existing properties: up to 70% LVR (30% deposit).
-
Interest Rates
Investment rates are typically 0.5–1% higher than owner-occupied. However, this interest is tax-deductible (subject to the interest deductibility rules).
-
Debt-to-Income Ratios
The Reserve Bank has introduced DTI restrictions. For investors, the limit is typically 7x your income.
Structuring Your Investment Portfolio
How you structure your investment lending can make a significant difference to your tax position and flexibility. Most investors choose interest-only lending for investment properties — this maximises cash flow and keeps your tax-deductible interest expense high.
Be careful about cross-securitising properties. While it can help you access more lending, it also means the bank has a claim over multiple properties if things go wrong. Many investors choose to bank their investment properties separately from their family home for protection and flexibility.
Fixed or Floating for Investors?
We generally recommend fixed interest rates — they're usually lower, provide certainty, and you'll benefit if market rates rise. However, floating rates may be appropriate if you're planning to repay the loan quickly after a buy-and-flip, as you'll avoid break fees.
How Long Should I Fix For?
We often recommend interest rate averaging — splitting your mortgage into portions fixed for different periods. For example, with a $300,000 investment mortgage and strong indications rates were about to decrease, we might recommend:
- $75,000 fixed for six months
- $150,000 fixed for one year
- $75,000 fixed for 18 months
You'd have regular chances to refix at lower rates, but if rates increased the change to repayments would be gradual.
Revolving Credit for Investors
Revolving credit is especially useful for investors completing renovations. It turns part of your mortgage into a large overdraft — you can progressively withdraw funds for renovations, repairs or construction as needed, and you won't pay interest on funds you haven't used. This is often better than a personal loan, with a lower interest rate.
Interest-Only Lending
We generally recommend principal and interest repayments, but interest-only may be appropriate when:
- You need cashflow to purchase more property
- During renovations or construction
- You only plan to hold a property briefly before selling for a capital gain

Key Considerations
-
Cash Flow vs Capital Growth
Different properties and locations suit different strategies. Understand whether you're investing for rental income or property value increase.
-
True Cost of Ownership
Factor in all costs: rates, insurance, maintenance, property management, and periods of vacancy.
-
Tax Implications
Talk to your accountant about the Bright-line test, interest deductibility rules, and ownership structure (personal, trust, or company).
-
Exit Strategy
Have a plan for when and how you'll exit the investment. This affects how you structure ownership and financing.
Choosing an Investment Strategy
Investing in property without a strategy is a bit like driving in the dark with your lights off — it probably won't end well. During your strategy meetings with Blueprint Finance, we'll work to understand what you want to achieve, whether that's being mortgage-free, retiring early, or funding a better lifestyle. Then we'll reverse-engineer a strategy to help you get there.
Common Investment Strategies
-
Buy and Hold
Purchase a property and rent it out for the long term. The priority is finding a property likely to increase in value with a high net rental yield. This is fairly hands-off with minimal specialist skill required, and holding long-term may reduce your exposure to market fluctuations. The ideal mortgage should be simple and low cost to maximise yield.
-
Buy, Renovate and Hold
Purchase a rental property that can be improved to increase its rental yield — by adding a room or making cosmetic improvements. Rental returns may be better than buy-and-hold, and renovations can help you build equity quickly. However, more investment is required upfront and you'll need confidence completing renovations. A revolving credit may help fund the work.
-
Buy and Flip
Purchase a property, renovate to add value, then sell for a capital gain. You'll get cash in hand much quicker, but this is the riskiest strategy — if you don't buy well or renovations go over budget, you could lose money. The ideal mortgage may include floating rates to avoid break fees and interest-only to maximise cashflow during the hold period.
A Note on Tax
As a property investor you'll be subject to taxes on rental income and potentially capital gains. It's always best to understand your tax obligations before you buy and sell property.
- You may be subject to the Bright Line Rule if you sell within a certain period (see below)
- If you buy with the intention of trading properties for a capital gain, you may need to pay income tax on your profit at your top marginal tax rate
- From April 2025, you can deduct 100% of your interest expenses from taxable property income
Tax on investment property can be complex. We always recommend that property investors speak to an experienced chartered accountant to optimise the tax efficiency of their investments. We know several great accountants — talk to us and we'll recommend someone who can help.
Understanding the Bright Line Rule: You must pay tax on profits from selling a property if you bought it: from 1 October 2015 to 29 March 2018 and sold within 2 years; from 29 March 2018 to 27 March 2021 and sold within 5 years; from 27 March 2021 to 1 July 2024 and sold within 10 years (5 years for new builds); or on/after 1 July 2024 and sold within 2 years. Exemptions include business premises, farmland, and your main home — speak to your accountant to be sure.
Buying the Right Property
You might be a property investor for 10, 20 or even 30 years, but a great deal of your returns will be determined the moment you buy. The property you choose will most likely be the difference between success and mediocre results.
Over the years we've seen that successful property investments often share a few things in common:
- They're in larger centres with populations exceeding 100,000
- They're in areas with growing populations
- Properties ideal for flipping are often in areas where demand is very high
- Good buy-and-hold investments tend to be low maintenance — an old villa may be great to flip but expensive to hold long term
- Good investments are often in areas where new infrastructure is being planned, such as new highways or train lines
With all that said, you should only ever buy a property that suits your investment strategy and your financial circumstances.
Rental Yield versus Capital Gains
Rental yield is the income your property generates, calculated as a percentage of its value. Net Rental Yield (%) = (Annual Income − Property Costs) ÷ Property Value.
The ideal property has high potential for capital gains and a high rental yield, but one often comes at the expense of the other. For example, the highest rental yields in the country are in the Grey District and Kawerau — areas not known for capital gains. Properties in Herne Bay have experienced incredible capital growth but rental yields can be as low as 2%.
The trick is to think about your strategy and circumstances when you buy. If you've got plenty of cash to top up the mortgage, focus on potential capital gains. If you don't, yield will be the priority.
Buying Below Market
Our team has been involved in thousands of transactions and we know the NZ property market well. We can help you assess a property's value during the offer phase, because buying well is the quickest way to gain equity as an investor.
Tips for buying below market:
- Be prepared to make low offers and have them declined
- Look for urgent sales and mortgagee sales
- Keep an eye out for properties that don't sell at deadline
- Build relationships with real estate agents for early heads-up on off-market sales — less competition often means lower prices
- Look for properties marketed poorly — bad photos and descriptions mean less competition, and the property could be a hidden gem
- Keep an eye out for vendors selling directly without an agent
Most importantly, always take your time. Don't get fixated on one property — the deal of the century comes around once a week, and there'll always be another.
Build Your Professional Team
As a property investor, you'll want to surround yourself with a team of professionals to help you make the hard decisions. At Blueprint Finance we've been in the industry for many years and have a huge network of professionals we can recommend, including:
- Conveyancers and solicitors
- Buyers agents and real estate agents
- Accountants
- Experienced building inspectors
- Insurance brokers and experts
- Property managers for rental properties
- Quantity surveyors if you plan to subdivide or build
- A good builder or project manager for renovations
Last but not least, it's a great idea to speak to a financial advisor and mortgage broker to make sure you're getting a competitive interest rate and that your mortgage is structured correctly.

From 3 properties to 5
A professional Auckland couple already owned three rentals worth around $3.35m, but under a standard lower-yield strategy their borrowing was capped near $800,000. The problem wasn't ambition — it was the type of property. We shifted the focus to 8%+ gross-yield income properties, so each new purchase strengthened servicing and supported the next.
Two further purchases added ~$2.15m of property and ~$174,200/yr in rent — taking the portfolio from 3 to 5 and lifting its yield from 4.3% to 5.8%.
