Most people searching for a mortgage broker have a home loan in mind. But if you are buying a shop, an industrial unit or an investment building, the lending works quite differently, and the adviser you choose matters.
This guide explains the difference between a commercial mortgage broker and a residential mortgage broker in NZ. It covers lender criteria, documentation and security, so you can approach the right adviser from day one.
What Does a Residential Mortgage Broker Do?
A residential broker helps individuals and families with loans secured over a home. That includes first home loans, refinancing, top-ups and residential investment purchases. Typical mortgage broker services include comparing lenders, estimating your borrowing power, preparing the application and managing it through to settlement. For a full rundown, see our checklist of what a broker handles.
Residential lenders mainly assess you as a person: your income, living expenses, debts and deposit. Consumer credit rules and Reserve Bank lending settings can also influence how much you can borrow and how large a deposit you need.
What Does a Commercial Mortgage Broker Do?
A commercial mortgage broker arranges finance secured over commercial property such as retail premises, offices, warehouses, mixed-use buildings and larger investment properties. A commercial property mortgage broker also works with business owners buying their own premises, and with investors whose income comes from tenants rather than wages.
Commercial lending is assessed differently. Lenders look closely at the property itself, the lease or rental income, and the strength of the borrowing entity, whether that is a company, a trust or an individual. Some deals also suit non-bank lenders when the timing or structure falls outside a main bank's policy.
Key Differences at a Glance
How income is assessed
Residential lending focuses on your personal income and expenses. Commercial lending looks at rental income, business cash flow, or both.Deposit and loan-to-value ratio (LVR)
Commercial loans commonly need a larger deposit, because lenders usually lend a lower percentage of the property's value.Loan term and structure
Commercial loans often have shorter terms, interest-only periods and a refinance or review point at the end, rather than one long principal and interest term.Documentation
Commercial applications usually add company financials, leases and property details to your personal information.Security
Lenders may ask for personal guarantees from directors, or extra security, alongside the property.Valuation and due diligence
A commercial valuer will typically assess lease terms, tenant quality, zoning and condition, which can take longer than a standard home valuation.

FAQ
Is a commercial mortgage broker more expensive than a residential one?
Fee arrangements vary. Residential brokers are often paid by the lender, while more complex commercial deals may involve fees. Ask for any fees to be explained in writing before you proceed.
Can one broker handle both residential and commercial loans?
Some can, but experience differs. Ask how often they arrange the type of loan you need and which lenders they use for it.
Do commercial property loans need a bigger deposit?
Usually, yes. Lenders commonly lend a lower share of a commercial property's value than a home's, so the deposit or equity required is often higher.
Can I use my home as security for a commercial purchase?
Sometimes. It can reduce the cash deposit you need, but it also puts your home at risk, so get legal and financial advice first.
How long does commercial loan approval take?
Often longer than a home loan, because of commercial valuations, lease reviews and legal due diligence. Timeframes vary by lender and property.
