The first open home can feel exciting right up until someone asks whether you have pre-approval. Working out how to buy first home is not just about finding a place you love. It is about knowing your numbers, understanding what lenders need, and being ready to act when the right property appears.
A good first-home plan gives you choices. It helps you avoid falling in love with a property outside your comfortable budget, making an offer with conditions you cannot meet, or taking on a loan structure that makes the years ahead harder than they need to be.
Start with what you can comfortably afford
Your borrowing limit is a useful starting point, but it is not the same as your ideal budget. Lenders assess your income, existing debts, regular commitments, deposit and household spending. They also test whether you could still manage repayments if interest rates rose.
That assessment is designed to protect both you and the lender, but your own budget needs to go further. Think about the real cost of owning the home: rates, insurance, maintenance, body corporate fees where relevant, moving costs and the everyday changes that come with a new location. A lower purchase price that leaves room to live, save and handle surprises can be a far better outcome than borrowing every dollar available.
If you are buying with a partner, have an irregular income, receive bonuses or are self-employed, get clear on the evidence behind your income early. Lenders may assess these situations differently. The right lender and presentation of your application can matter as much as the headline income figure.
Build a deposit and understand where it comes from
For many first-home buyers, the deposit is the biggest hurdle. Savings are the obvious source, but they may not be the only one. Depending on your circumstances and current eligibility rules, you may be able to use KiwiSaver, receive a family gift or access a low-deposit lending option.
A gifted deposit needs to be documented properly. A lender will generally want to know whether it is a genuine gift or money that must be repaid, because repayment obligations affect affordability. Keep a clear trail for savings and transfers too. Large unexplained deposits in your account can slow an application down when the bank asks questions.
Low-deposit lending can help you buy sooner, but it comes with trade-offs. You may have fewer lender options, pay a higher interest rate or face additional costs. Sometimes waiting to build a larger deposit is the smarter move. Sometimes buying sooner is right because your income, location and long-term plans make the numbers work. This is where tailored advice is more useful than a one-size-fits-all rule.
Get pre-approval before you make serious offers
Pre-approval tells you how much a lender may be prepared to lend, subject to conditions. It gives you a realistic buying range and makes you a more credible buyer when you are negotiating with an agent or vendor.
It is not a blank cheque. Pre-approval usually has an expiry date and may depend on the property meeting the lender’s criteria. The lender will still need to approve the specific home, review a valuation if required, and confirm that your financial position has not changed.
That means it is wise to keep your finances steady while you are house hunting. Avoid taking out a new car loan, buying furniture on finance, changing jobs without discussing it first or running up credit card balances. Even a small change can affect the final approval.
A mortgage adviser can assess your position before an application is submitted, identify suitable lenders and explain the conditions attached to each option. Mortgage Time works for you, not a single bank, so the focus is on finding a loan structure that suits your goals and circumstances.
Know the full cost of buying your first home
Your deposit is not the only money you need available. Before you start attending open homes every weekend, allow for legal fees, building reports, valuation costs if the lender requires one, insurance, moving expenses and any immediate work the property needs.
It is easy to focus on the purchase price and overlook the first few weeks after settlement. You might need curtains, appliances, a lawnmower, repairs, or simply a buffer while bills settle into a new rhythm. Keeping some savings aside can make homeownership feel far less stressful.
The property type also affects your ongoing costs. A standalone home may offer more freedom but require more maintenance. An apartment or townhouse can be lower maintenance, yet body corporate levies and rules may apply. New builds can be appealing for their lower maintenance needs, but you still need to understand the contract, completion timing and lender requirements.
House hunt with a clear checklist
Once you have pre-approval, you can look with purpose. Start with the non-negotiables: commute, schools if relevant, access to family, number of bedrooms, parking and the type of home you can realistically maintain. Then separate those needs from preferences such as a renovated kitchen or a particular suburb.
At an open home, look past styling. Check for signs of dampness, cracks, drainage issues, unconsented work and deferred maintenance. Ask for the property files and review the title, Land Information Memorandum and any body corporate documents with your solicitor where relevant. A building inspection is an upfront cost, but it can uncover problems that are expensive to fix later.
Do not assume every property will be acceptable to every lender. Small apartments, leasehold properties, homes with unusual construction or properties needing substantial work can have different lending rules. Raise the property details with your adviser before you commit.
Make an offer that protects you
Buying a home is a legal commitment, not just a handshake after an auction or negotiation. Have your solicitor review the sale and purchase agreement before you sign it. If you are buying by negotiation, you may be able to include conditions for finance, a building report, a valuation or due diligence. The wording and timeframes matter.
Auctions need extra care because bids are generally unconditional. You need your finance, legal checks, insurance and property due diligence sorted before auction day. If you are interested in an auction property, talk to your adviser and solicitor early rather than assuming your pre-approval covers every detail.
When deciding what to offer, leave emotion at the door as much as possible. Set a maximum figure based on your budget and the property’s value to you. Missing out can be disappointing, but stretching beyond a sensible limit can turn a dream home into a financial burden.
Choose a loan structure for real life
The lowest advertised rate is only one part of a good mortgage decision. Your loan structure should reflect how you expect to live and earn over the next few years.
A fixed rate provides certainty for an agreed period, which can make budgeting easier. A floating rate generally offers more flexibility, including the ability to make extra repayments without fixed-loan break costs. Many first-home buyers use a mix of fixed terms so the entire loan does not come up for renewal at once. The best approach depends on your cash flow, plans to make lump-sum repayments and appetite for certainty.
Also consider how repayments will work if one income changes, you plan to start a family, or you expect to renovate. A loan can be approved today and still be unsuitable for the life you are building tomorrow. Ask questions until you understand the repayment amount, interest rate type, fees, features and what happens if you need to change course.
Prepare for settlement, then give yourself time
Once your offer is unconditional, the finish line is in sight, but there are still important jobs to complete. Arrange insurance from the required date, meet any remaining lender conditions, sign loan documents and make sure your solicitor has what they need. Avoid financial surprises during this period.
Settlement day is a milestone, not the moment you need to have every room perfect. Give yourself permission to settle in gradually. Prioritise essential repairs, establish a realistic household budget and keep building your savings buffer. Owning your first home is a long-term step, and the best decisions are usually the calm, well-planned ones.
The right home is not only the one that looks good at an open home. It is the one you can buy with confidence, afford through changing seasons and make your own over time.
