Everything You Need to Know About Downsizing Your Home

Why Downsizing Isn't Always About Reducing Your Mortgage

Downsizing doesn't automatically mean you'll end up with a smaller mortgage. Many people moving to a smaller home in Wellington discover that while the property is physically smaller, it might sit in a more desirable location or come with lower maintenance costs that shift where their money goes each month. The real advantage often shows up in what you do with the equity you release, not just in a lower loan balance.

Consider someone who sells a four-bedroom home in Tawa and moves into a two-bedroom townhouse in Mount Victoria. The townhouse might cost nearly as much as what they sold, but they've cut their weekly maintenance, reduced rates, and positioned themselves closer to the CBD. The loan structure might look similar on paper, but their cashflow improves because the overall cost of ownership drops. That's where a mortgage adviser can help you model different scenarios before you commit to a sale.

If you're selling a larger home with an existing mortgage, your lender will need to discharge that loan and set up a new one for the property you're buying. That process involves break costs if you're on a fixed rate, and it's worth knowing those figures before you list your current home. A mortgage broker can request break cost estimates from your lender so you know exactly what you're working with.

How Much Equity Can You Actually Access When You Downsize?

Your usable equity is the difference between what your home sells for and what you still owe on your mortgage, minus selling costs and any break fees. If your Wellington home sells for $950,000 and you owe $320,000, you're looking at roughly $630,000 before you deduct real estate fees, legal costs, and potential fixed rate break costs. Those selling costs can add up to $30,000 or more depending on your agent's commission structure and your loan situation.

Once you know your net equity, you can decide how much to put toward your next home and whether to keep some funds aside for renovations, travel, or simply reducing your ongoing mortgage commitment. Some buyers in their late fifties or early sixties choose to pay off their mortgage entirely when they downsize, which removes that monthly repayment and frees up income for other priorities. Others prefer to keep a smaller mortgage and invest the remaining equity elsewhere, especially if they're still working and comfortable with the repayment.

One thing that catches people off guard is the settlement timing. If your sale and purchase don't settle on the same day, you might need bridging finance to cover the gap. That's more common when you're buying in a competitive area like Kelburn or Oriental Bay, where sellers aren't always willing to wait for your own sale to go through. Bridging finance typically runs for a few weeks to a few months and carries a higher interest rate than a standard home loan, so it's worth factoring into your budget if the timing doesn't line up neatly.

What Happens to Your Interest Rate When You Refinance for a Downsize?

When you move to a new property, you're setting up a new mortgage, which means you'll be offered whatever rates are available at the time you apply. If you've been on a fixed rate for the past two or three years, current rates might be higher or lower depending on where the market has moved since you last locked in. Your LVR also plays a role in what rate you'll be offered.

If you're borrowing less than 80% of your new property's value, you'll typically access standard rates without any low equity margin or Low Equity Premium. Many people downsizing find themselves in this position because they're carrying over a decent chunk of equity from their previous home. For example, if you're buying a $700,000 unit in Johnsonville and putting down $400,000 from your sale proceeds, your LVR sits around 43%, which puts you in a strong position with most lenders.

Your income still matters, even if your loan amount is dropping. Lenders assess whether you can service the new mortgage based on your current income and outgoings, and if you're retiring soon or already retired, they'll look at your pension, KiwiSaver withdrawals, or any other regular income streams. Some lenders are more flexible than others when it comes to lending to retirees, so it's worth talking through your situation with someone who knows which banks are more accommodating in that space.

Should You Fix, Float, or Split Your New Home Loan?

A floating rate gives you flexibility to make lump sum payments or pay off the loan early without penalties, which suits people who plan to chip away at their mortgage quickly or who might sell again within a few years. Fixed rates lock in your repayment amount for a set period, which makes budgeting more predictable but limits your ability to make extra repayments or exit the loan without break costs.

Many people downsizing choose to split their mortgage between fixed and floating. You might fix 60% of the loan on a two-year term to lock in some certainty, then leave 40% floating so you can make extra repayments if you receive a lump sum from an inheritance, investment maturity, or other windfall. That combination gives you both stability and flexibility without locking yourself into one rigid structure.

If you're planning to pay off the mortgage within a few years, a floating rate or a short fixed term makes more sense than locking in for five years. Break costs on a long fixed term can be significant if you decide to pay off the loan early, and those costs can eat into the equity you've worked hard to build. Your mortgage adviser can show you how different rate structures affect your total cost over the period you expect to hold the loan.

Revolving Credit and Offset Options for Downsizers

Revolving credit works like a large overdraft secured against your home. You can deposit your income into the account, draw on it when you need to cover expenses, and only pay interest on the amount you're actually using at any given time. If you're downsizing and keeping a portion of your equity liquid, a revolving credit facility lets you park that money in the loan account to reduce interest without locking it away.

An offset mortgage links your savings or transaction account to your home loan, so the balance in your savings account offsets the amount of interest you pay on the mortgage. If you have $50,000 sitting in an offset account and a $300,000 mortgage, you're only charged interest on $250,000. That structure works well if you want to keep your savings accessible while still reducing your interest cost.

Not all lenders offer offset mortgages in New Zealand, and the ones that do often reserve them for specific loan sizes or customer segments. Revolving credit is more widely available, but it requires discipline because it's easy to dip into that facility for non-essential spending. If you're confident with managing your cashflow, revolving credit can save you thousands in interest over the life of the loan. If you prefer a more hands-off approach, a standard table loan with the option for extra repayments might suit you just as well.

How Downsizing Affects Your Lending If You're Close to Retirement

Lenders assess your ability to service a mortgage based on your income, and if you're retiring in the next few years, they'll want to see proof that your income will continue beyond your last day of work. That might include your NZ Super entitlement, rental income from an investment property, dividends from investments, or regular withdrawals from KiwiSaver.

Some banks cap the loan term based on your age, which can affect how much they're willing to lend or what your repayments look like. If you're 62 and applying for a 30-year mortgage, the lender might reduce the term to 15 or 20 years, which increases your minimum repayment even if you're borrowing less overall. Other lenders take a more flexible view and assess the application on the strength of your overall financial position rather than applying a blanket age-based policy.

If you're planning to downsize and retire within a few years, it's worth structuring your home loan in a way that aligns with your retirement income. That might mean choosing a shorter fixed term so you're not locked into high repayments if your income drops, or opting for interest-only repayments for a period while you adjust to your new cashflow. Interest-only loans aren't as common for owner-occupied properties as they are for investment lending, but some lenders will consider them if your equity position is strong and you have a clear plan for paying down the principal over time.

What to Watch for With Settlement Timing and Bridging Finance

When you're selling one home and buying another, the settlement dates don't always match up. If your new property settles before your sale goes through, you'll need bridging finance to cover the shortfall. Bridging loans are short-term facilities that let you complete the purchase while you wait for your sale proceeds to arrive, and they're secured against both properties until your sale settles.

Bridging finance usually costs more than a standard mortgage because the lender is carrying more risk over a short period. Interest rates can sit a few percentage points higher than your typical floating rate, and some lenders charge an establishment fee or ongoing facility fee on top of that. If your sale is delayed for any reason, those costs can add up quickly, so it's worth building in a buffer if you're relying on bridging to make the move happen.

In some cases, you can negotiate a delayed settlement on your purchase to avoid bridging altogether. Sellers aren't always willing to wait, especially in areas like Miramar or Karori where demand is consistent and they have other offers on the table. If you're in a strong position with a pre-approved loan and a sold property, you might have more room to negotiate a settlement date that works for both sides. Your solicitor and mortgage broker can work together to structure the timing in a way that minimises your bridging costs and keeps the process moving without unnecessary holdups.

Downsizing can give you more financial breathing room, but only if you structure the move in a way that suits your actual circumstances. Call one of our team or book an appointment at a time that works for you.
