Unlock the wealth in your property. Access home equity for renovations, investments, or consolidating debt.
Calculate Your Available EquityHome equity is the portion of your property that you truly own - the difference between your home's current market value and what you owe on your mortgage.
Based on recent comparable sales or registered valuation
What you still owe the bank
Every mortgage payment includes principal repayment, reducing what you owe and increasing your equity.
Example: Paying $400/month in principal = $4,800 extra equity per year
As your property appreciates in value, your equity grows even without paying down the mortgage.
Example: 5% annual growth on $1M home = $50,000 extra equity per year
Banks won't let you borrow 100% of your equity. They require you to maintain a buffer to protect both you and them from market fluctuations.
Owner-Occupied Property
Living in the property yourself
Banks lend up to 80% of property value (you keep 20% equity minimum)
Investment Property
Rental properties you own
More conservative lending for investment properties (you keep 35% equity minimum)
Scenario: $1M home with $600K mortgage (40% equity, 60% LVR)
This calculation assumes you meet income serviceability requirements and have good credit history.
Increase your existing mortgage amount. The bank pays you the difference in cash, and you repay it as part of your regular mortgage. Learn about refinancing →
Best for: Large lump sum needs ($50K+), one-time projects
Pros: Lowest rate, simple structure, easy to understand
Cons: Refinancing costs ($1,500-$3,000), less flexibility
Acts like a giant overdraft against your home. Borrow and repay as needed within your approved limit. Only pay interest on what you use.
Best for: Ongoing expenses, business use, property developers
Pros: Maximum flexibility, only pay interest on amounts used
Cons: Higher interest rate (floating only), requires discipline
Your transaction account is linked to your mortgage. Savings offset mortgage interest, and you can redraw if needed (effectively accessing equity).
Best for: People with fluctuating income or expenses
Pros: Tax-effective savings, interest savings, emergency access
Cons: Higher interest rate than fixed, complex to understand
Separate loan secured against your property equity, in addition to your primary mortgage. Usually from non-bank lenders.
Best for: Can't refinance main mortgage (high break fees), bad credit
Pros: Avoid breaking main mortgage, faster approval
Cons: Much higher interest rates (9-15%), higher fees
Property Renovations (Value-Adding)
Kitchen, bathroom, adding bedrooms. Can add more value than cost. Typical ROI: 70-120%.
Investment Property Deposit
Use equity to fund deposits on rental properties →, building wealth through leverage.
Business Investment
Fund or expand a business with proven track record. Lowest-cost business funding available.
Debt Consolidation (High Interest)
Pay off credit cards, personal loans. Save thousands on interest annually. Learn more →
Medical Expenses (Essential)
Necessary medical procedures not covered by insurance. Health is wealth.
Education (ROI-Positive)
Professional qualifications or degrees that significantly increase earning potential.
Cars or Vehicles
Depreciating assets on 25-year debt. Consider if truly necessary for work/business.
Holiday or Travel
Paying for 25 years for a 2-week holiday is financially questionable. Save up instead.
Maintenance/Repairs
Necessary but doesn't add value. Try to cash-flow these rather than borrow if possible.
Lifestyle Spending / Consumer Goods
TVs, furniture, clothes, gadgets. Never borrow against your home for depreciating consumer items.
Gambling or Speculation
High-risk investments, crypto, penny stocks. Recipe for losing your home.
Paying Off Debt Just to Run It Up Again
If you haven't fixed spending habits, you'll be in worse position after consolidation.
Gifting Money to Family
While generous, puts your own financial security at risk. Only do if you can easily afford it.
Lawyer fees to vary your mortgage and register changes with Land Information NZ.
Banks may require registered valuation. Some waive this for lower amounts or use automated valuations.
Some lenders charge application fees, though many waive these in competitive market.
If you're breaking a fixed-rate mortgage, break fees can be substantial. Time refinancing for when fixed term expires.
If accessing $100K+ equity, these costs represent just 1-2.5% - usually worthwhile for valuable uses.
Cashback Offers: Some banks offer cash incentives ($1,000-$3,000) when refinancing, which can offset most or all of these costs.
You're increasing your mortgage balance, meaning more interest and longer time to pay off. If you can't make repayments, you risk losing your home through mortgagee sale.
If property values drop significantly, you could end up in negative equity (owing more than the house is worth), making it difficult to refinance or sell.
Higher mortgage balance means greater exposure to interest rate increases. A 2% rate rise on extra $100K borrowed = $2,000/year extra in payments.
Spreading debt over 25-30 years means paying substantially more interest over time, even at low rates. Can delay debt freedom and retirement.
Easy access to large amounts of money can lead to unnecessary spending on wants rather than needs. Requires strong financial discipline.
If staying with your current lender (topping up existing mortgage), typically 2-3 weeks from application to funds. If refinancing to a new lender, allow 4-6 weeks. Urgent situations can sometimes be expedited.
Yes, but you'll need 2+ years of financial statements showing consistent profitability. Banks are more conservative with self-employed applicants. A mortgage broker experienced with self-employed lending is highly recommended.
Yes, banks want to know the purpose. They're more likely to approve for value-adding renovations or investment than for holidays or lifestyle spending. Be honest - banks can decline applications if they think the purpose is too risky.
Only if you use the borrowed equity for income-earning purposes (e.g., investment property deposit, business investment). If used for personal purposes like renovations on your own home, the interest is not tax deductible. Consult an accountant for specific advice.
You can only access equity based on current value, not what you paid. If your property value has dropped, you may have less equity available than you think. Banks will require a registered valuation to confirm current value.
Difficult with mainstream banks. You may need to improve your credit first, or explore non-bank lenders who charge higher rates (9-15%). If you have significant equity (50%+), more options become available despite credit issues.
