INVESTMENT PROPERTY LENDING SUPPORT
You’ve got equity.
The bank says you’ve hit your limit.
Let’s look at that again.
This is one of the most common conversations we have with NZ property investors. The equity is there on paper. The bank says it can’t be touched. And so the next purchase stalls.
The Mortgage Guy is a New Zealand mortgage broker specialising in investment property lending. We understand how LVR restrictions, DTI limits, and loan structure interact, and we know how to navigate them so your portfolio can keep moving.
If you’ve been told no, or told to wait, it’s worth getting a second opinion.
INVESTMENT MORTGAGE AND LENDING
The rules for investors are different,
and they keep changing.
Investment property lending in New Zealand carries its own set of restrictions that don’t apply to owner-occupiers.
30% Minimum deposit for most investment properties
DTI CAP
7x Debt-to-income limit against gross income
RENTAL INCOME
70-80%Typical shade rate before lenders use it in calculations
Investors with strong equity positions and well-performing portfolios find themselves blocked by rules they didn’t know existed, or trapped in structures they didn’t realise were limiting them.
Cross-collateralisation is one of the most common traps. It’s where a bank links all your properties under one security umbrella. It feels convenient until you want to sell one property, access your equity, or move your lending. At that point, the bank holds the cards.
Interest deductibility has been fully restored from 1 April 2025, meaning investors can once again claim 100% of mortgage interest as a tax deduction on residential rental properties. If you adjusted your portfolio during the Labour-era restrictions, it’s worth reviewing whether your current loan structure is still right.
What we work through with you:
- Your actual borrowing position, accounting for LVR and DTI limits
- How to access equity without cross-collateralising your existing properties
- Interest-only versus principal and interest, and how each affects cash flow and future capacity
- Which lenders suit investment lending and how they assess rental income differently
- How the 30% deposit rule applies to your situation, and whether new build exemptions are relevant
- How to structure lending across multiple properties so each purchase doesn’t close the door on the next

Ashley is a financial adviser. That means the guidance you’re getting on loan structure is regulated advice, not just a broker running numbers.
WHO THIS IS FOR
This is for you if:

- Your bank says you’re at your limit but you know you have equity sitting unused
- You’re cash-flow neutral or negative and want to understand whether your loan structure is the problem
- You own your home and want to use your equity to get into your first investment property
- You already have one or more investment properties and want to grow the portfolio without the one-bank trap
- You didn’t realise your properties were cross-collateralised until it became a problem
- You want a mortgage broker who understands investor lending, not just standard home loans
You don’t need a fully formed plan before you reach out. A lot of investors come to us at the thinking stage, or after a bank decline, and leave with a clear picture of what’s actually possible and what to do next.

Frequently Asked Questions
Why do I need a 30% deposit for an investment property?
The Reserve Bank requires most lenders to apply a maximum LVR of 70% on investment property lending. That means you need at least 30% equity or deposit. Some exceptions apply, particularly for new builds, and a small proportion of loans can sit below this threshold. We’ll tell you exactly where you stand and whether any exceptions are relevant to your situation.
The bank says I’ve hit my debt-to-income limit. What does that mean?
From July 2024 the Reserve Bank capped investor borrowing at seven times gross income. So if you earn $120,000 and already carry $840,000 in debt across your properties, you’re at your ceiling regardless of how much equity you have. It’s one of the most common blockers for mid-stage investors right now. The solution often involves restructuring existing debt or approaching lenders who use available DTI headroom differently.
What is cross-collateralisation and why does it matter?
Cross-collateralisation is when a bank links all your properties under one security structure. It simplifies their administration but limits yours. If you want to sell one property, refinance, or access equity, the bank can effectively block the move because all assets are tied together. We help investors avoid this trap from the start, or work out of it if they’re already in it.
Can I use equity in my home as a deposit for an investment property?
Yes, this is one of the most common approaches and often the most effective way to get started in investment property. We look at your usable equity, how to structure the draw-down separately from your home loan, and how to do it without cross-collateralising the two properties.
Does interest deductibility apply to my investment property now?
Yes. From 1 April 2025, full interest deductibility was restored for residential rental properties, meaning you can claim 100% of your mortgage interest as a tax deduction. If you restructured your portfolio or exited the market during the Labour-era restrictions, it’s worth reviewing whether your current setup takes full advantage of this.

Our role is to support the lending side of your investment journey, so your finance is set up correctly and sustainably from day one.


Mortgage Warrant of Fitness
Think of it as an annual health check, but for your finances. Just like you’d service your car to keep it running smoothly, your mortgage needs regular attention to make sure it’s still the best fit for you.
A quick review can uncover savings or smarter strategies you might otherwise miss. It’s about keeping your mortgage in top condition, so you can focus on building your future, not stressing over repayments.
Asset Loans
From cars and boats to caravans, motorcycles, and work vehicles, asset finance helps you enjoy the things that make life easier and more rewarding. We’ll help you secure tailored lending with flexible terms, fair rates, and a smooth approval process that fits your lifestyle or business needs. So whether it’s hitting the road, the water, or the next job site, you can move forward with confidence knowing your finance is working for you.


Self-Employment Lending
Traditional banks often struggle to understand self-employed income, making it harder for business owners, contractors, and freelancers to secure finance. We partner with lenders who specialise in self-employed clients, helping present your income in the best light and structuring solutions that reflect the reality of running a business, so your hard work opens doors to homeownership, not roadblocks.
Construction & Business Loans
From building your dream home to tackling major renovations or fueling your business growth, the right loan structure makes all the difference. We help you secure tailored finance solutions that provide the flexibility, staged funding, and competitive rates you need. So whether it’s a new build, an upgrade, or expanding your business, you’ve got the support to bring your plans to life.


Refinancing & Top-Ups
Whether you’re looking to secure a better rate, reduce repayments, or unlock equity for renovations, investments, or life’s big opportunities, refinancing and top-ups can give you more flexibility and control. We’ll review your current loan, compare options across lenders, and structure a solution that supports your goals. So your mortgage works harder for you, not the other way around.
