How many units can I have before needing commercial finance?

This varies by lender, but typically properties with up to four units can be financed with residential loans. Five or more units often require commercial lending products with different terms and conditions. Some lenders have different thresholds, so shop around.

Are multi-unit properties harder to sell?

The buyer pool is smaller because multi-units appeal mainly to investors, not owner-occupiers. However, they remain in demand from investors seeking yield. Properties with unit titles can be sold individually, expanding your exit options.

Do I need separate insurance for each unit?

For properties on a single title, one policy typically covers the building with appropriate multi-unit provisions. For unit titles, you may need individual policies or contribute to body corporate insurance. Discuss your specific situation with an insurance broker experienced in investment properties.

Can I convert a house into a multi-unit property?

Potentially, but this requires council consent for the conversion. You will need to meet building code requirements for each dwelling, including fire safety, healthy homes standards, and parking provisions. The cost and complexity can be significant, so get professional advice before proceeding.

Multi-Unit Investment Property NZ

Multi-unit properties, including duplexes, blocks of flats, and converted homes with multiple dwellings, offer investors the opportunity to generate more rental income from a single purchase. This strategy can accelerate portfolio growth and improve cash flow.

Instead of buying multiple standalone houses, a multi-unit property allows you to acquire several income streams with one transaction, one set of purchase costs, and often better overall yields. However, these properties come with their own considerations that investors need to understand.

Types of Multi-Unit Properties

Duplexes

A duplex consists of two separate dwellings, either side by side or stacked. They are popular with investors because they offer dual income while looking like a standard residential property. Many duplexes were purpose-built, while others are converted large homes.

Blocks of Flats

These are buildings containing three or more separate units. They can range from small three-unit blocks to larger complexes. The more units, the greater the potential income, but also the more intensive the management requirements.

Converted Properties

Large older homes sometimes get converted into multiple flats. These can offer good value but require careful due diligence around consents, fire safety, and building standards compliance.

The Benefits of Multi-Unit Investment

Higher Yields

The combined rent from multiple units typically exceeds what a single dwelling on the same land would achieve. A duplex might rent for $500 per unit ($1,000 total) where a single house would fetch only $650. That higher income translates to better yields.

Yield Comparison Example:

Single house: $800,000 purchase, $650/week rent = 4.2% gross yield
Duplex: $950,000 purchase, $1,000/week rent = 5.5% gross yield
Four-unit block: $1.4M purchase, $1,800/week rent = 6.7% gross yield

Reduced Vacancy Risk

With multiple tenants, a single vacancy does not mean zero income. If one of your four units is empty, you still have 75% of your rental income coming in. This provides more stable cash flow compared to a single-tenancy property where vacancy means complete income loss.

Efficiency of Scale

Managing multiple units in one location is more efficient than properties scattered across different areas. One site visit can address issues in multiple units. Insurance, rates, and some maintenance costs may be lower per unit than for separate properties.

Challenges to Consider

Financing Complexity

Some lenders are cautious about multi-unit properties. They may require larger deposits, charge higher interest rates, or have specific lending criteria. Properties with more than four units often fall outside standard residential lending and may need commercial loan products.

Financing Considerations:

Some lenders cap at 2-4 units on one title
LVR requirements may be stricter
Valuation methods may differ from standard residential
Larger blocks may require commercial lending

More Intensive Management

More tenants means more tenant interactions, more maintenance requests, and more turnover to manage. Shared spaces like driveways, lawns, and rubbish areas can create disputes between tenants that require landlord intervention.

Concentrated Risk

While vacancy risk is spread across units, other risks are concentrated. A fire or natural disaster affects all units at once. A problematic location impacts all your tenants. You do not have the geographic diversification of properties in different areas.

Due Diligence for Multi-Unit Properties

Key Checks for Multi-Unit Purchases:

Title structure: Single title, cross-lease, unit title, or freehold?
Consents: Were all units properly consented and code compliant?
Fire safety: Smoke alarms, egress, and compliance with fire regulations
Healthy homes: Does each unit meet all healthy homes standards?
Separate metering: Are utilities separately metered for each unit?
Body corporate: If applicable, review rules, levies, and financial health

Title Structures Explained

How multi-unit properties are titled significantly affects your ownership rights and obligations:

Freehold single title: You own everything outright. Simplest structure but you cannot sell units individually.

Unit titles: Each unit is a separate title with shared ownership of common areas through a body corporate. Units can be sold separately, but you have body corporate obligations.

Cross-lease: You lease your unit from a shared freehold. Changes often require other owners' consent. Can be complicated if relationships sour.

Managing Multi-Unit Properties

Good systems become essential with multiple tenants. Consider using property management software to track rents, maintenance, and lease dates. Clear communication about shared responsibilities and house rules helps prevent disputes.

Many investors with multi-unit properties use professional property managers. The management fees are spread across more rent, making them proportionally affordable, and the time savings are significant.

The Bottom Line

Multi-unit properties can be excellent investments, offering higher yields, reduced vacancy risk, and efficient portfolio growth. They suit investors who want to maximise income and are comfortable with more intensive management.

Success requires careful due diligence, particularly around consents, title structure, and compliance. Work with lenders experienced in multi-unit finance, and consider professional management to handle the increased complexity. With the right property and approach, multi-unit investment can significantly accelerate your wealth-building journey.
