First Home Buyer Guide to Using a Mortgage Broker
Buying your first home in New Zealand is a major milestone. For many first home buyers, the mortgage process can feel overwhelming. A mortgage broker acts as your personal guide through the lending landscape. They can help you compare lenders, understand your borrowing power, and navigate the paperwork.
This guide explains how a mortgage broker works, when to use one, and how to get the best outcome for your first home purchase.
What is a mortgage broker?
A mortgage broker is a licensed professional who connects borrowers with lenders. They work with multiple banks and non-bank lenders, not just one. In New Zealand, brokers must be registered under the Financial Service Providers Register (FSPR) and comply with the Credit Contracts and Consumer Finance Act (CCCFA).
Brokers earn a commission from the lender when your loan settles. Many also charge a fee to the borrower, but this varies. Some offer their service at no direct cost to you.
Key concepts for first home buyers
- Borrowing power – How much a lender is willing to lend you based on your income, expenses, and deposit.
- Pre-approval – A conditional approval from a lender before you find a property. It shows sellers you are serious.
- Interest rate – The cost of borrowing, usually expressed as an annual percentage. Fixed or floating options are available.
- Loan-to-value ratio (LVR) – The loan amount compared to the property value. First home buyers often need a 20% deposit, but some lenders accept 10% with low equity fees.
- KiwiSaver First Home Withdrawal – You can withdraw most of your KiwiSaver savings (minus $1,000) to use as part of your deposit.
- First Home Grant – A government grant of up to $10,000 per person (depending on property price and location) for eligible first home buyers.
Step-by-step guide to using a mortgage broker
Step 1: Find a reputable broker
Look for a broker who specialises in first home buyers. Ask friends, family, or your real estate agent for recommendations. Check they are on the FSPR register and have good reviews. Many brokers offer a free initial consultation.
Step 2: Gather your documents
Your broker will need a clear picture of your finances. Prepare these items:
- Proof of identity (passport or driver’s licence)
- Recent payslips (usually 3 months)
- Bank statements (typically 3 months)
- Tax returns or IRD summary (if self-employed)
- Details of any debts (credit cards, student loans, car loans)
- KiwiSaver statements
- Details of your savings and deposit
Step 3: Discuss your goals and budget
Your broker will ask about your income, expenses, property price range, and timeline. Be honest about your spending habits. This helps them find the right lender and loan structure for you.
Step 4: Get pre-approval
Your broker will submit your application to one or more lenders for pre-approval. This usually takes a few days. Pre-approval gives you confidence when house hunting. It also shows sellers you are ready to buy.
Step 5: Compare loan options
Your broker will present you with loan options. Each will have different interest rates, fees, and features. Common options include:
- Fixed rate – Interest locked for 1–5 years. Good for budgeting.
- Floating rate – Variable rate that can change. Offers flexibility for extra repayments.
- Offset account – A transaction account linked to your loan. The balance reduces interest charged.
- Revolving credit – A flexible loan where you can draw and repay funds as needed.
Step 6: Make an offer and secure your loan
Once you find a property and your offer is accepted, your broker will work to turn pre-approval into full approval. They will coordinate with the lender, your lawyer, and the vendor’s solicitor. This process typically takes 2–4 weeks.
Step 7: Settlement
On settlement day, the lender transfers the loan funds to your lawyer. The property title is transferred to you. Your broker will confirm everything is in order and answer any last questions.
Pros of using a mortgage broker
- Access to multiple lenders – Brokers compare products from 10+ banks and non-banks, not just one.
- Time-saving – They handle paperwork and communication with lenders.
- Expert guidance – Brokers understand the CCCFA, LVR rules, and first home buyer grants.
- Often no upfront cost – Many brokers are paid by the lender, so their service is free to you.
- Tailored advice – They consider your unique situation, not just the cheapest rate.
Cons of using a mortgage broker
- Not all lenders are included – Some banks (e.g. TSB, Heartland) may not work with brokers.
- Commission structure – Brokers earn a commission from lenders, which may influence their recommendations.
- Potential fees – Some brokers charge a fee (usually $500–$1,500) if you take out a loan. Always ask upfront.
- Less control – You rely on the broker to communicate with the lender. Delays can happen.
- Not a substitute for your own research – You still need to understand the loan terms yourself.
Fees to expect
| Fee type | Typical amount | Who pays? |
|---|---|---|
| Broker commission (from lender) | 0.6%–1.0% of loan amount | Lender |
| Broker fee (if charged) | $0–$1,500 | Borrower |
| Application fee (from lender) | $0–$500 | Borrower |
| Valuation fee | $400–$800 | Borrower |
| Legal fees | $1,500–$3,000 | Borrower |
Who should use a mortgage broker?
A mortgage broker is ideal for first home buyers who:
- Are short on time and want a streamlined process
- Have complex finances (self-employed, irregular income, or past credit issues)
- Want to compare multiple lenders without contacting each one
- Need help understanding first home buyer grants and KiwiSaver options
If you prefer to deal directly with a bank and already have a strong relationship, a broker may not be necessary. But for most first home buyers, a broker adds significant value.
Tips for working with a mortgage broker
- Ask about fees upfront – Confirm whether the broker charges a fee and how they are paid.
- Check their panel – Ask which lenders they work with. A wide panel gives you more choice.
- Be transparent – Share all your financial details, including debts and spending. Hiding information can lead to a declined application.
- Get everything in writing – Request a copy of the loan offer and disclosure documents.
- Don’t rush – Take time to understand the loan terms, especially the interest rate, fees, and break costs.
- Compare with a direct bank – It’s fine to get a quote from a bank yourself. A good broker will match or beat it.
Verdict
A mortgage broker can simplify your first home buying journey. They offer expert advice, access to multiple lenders, and can save you time and stress. For most first home buyers, the benefits outweigh the drawbacks. Just remember to ask about fees, check their panel, and do your own research before committing. A good broker will be transparent and work in your best interests.
