New Zealand's housing supply is shifting—more townhouses and units are entering the market.

According to NZ Adviser, that's opening a window for upsize buyers, with the price gap to a bigger home reportedly "more favourable than it was at the height of the market."

What is Valuation Gap?

If you're upsizing, it's not just about what your current home is worth. It's about the gap between that number and the price of your next home.

A narrower gap means less to bridge with savings or borrowing
A wider gap means more

If you're planning to sell your starter home and move up to something bigger this spring, here's how to make sense of that opportunity

1. Get a Comparative Market Analysis (CMA)

A single agent's appraisal can lean toward what gets them the listing, but it's not always the sharpest read on today's market.

✅ What to do:

Ask two local agents for a CMA independently. Compare the two.

Close together? You've got a reliable number.
Far apart? That gap itself tells you something. Dig into why before you price anything.

2. Compare NZ Property Sales by Price Per Square Metre

A $50,000 difference between two comparable sales means little if one home is 40sqm bigger.

✅ What to do:

Ask your agent or pull it yourself from REINZ or Realestate.co.nz for price-per-square-metre on recent sales in your target size range.

It's the number that tells you if a home is fairly priced.

3. Ask for Bridging Finance Pre-Approval, Not Standard Pre-Approval

Standard pre-approval assumes you're buying with a deposit in hand. If you're selling to buy, you likely need something different.

Bridging finance covers the gap between buying your next home and settling the sale of your current one. Not every pre-approval accounts for this.

✅ What to do:

Ask your adviser directly : does this pre-approval assume bridging, or assume your current home has already sold?

4. Model Sell-First vs Buy-First Scenarios with Your Adviser

Most people only plan for one order of events. Knowing both in advance means you're not deciding under pressure if the timing doesn't go the way you assumed.

✅ What to do:

Ask your adviser to run the numbers both ways:

What does it look like if you sell before you find your next home?
What does it look like if you find your next home before your current one sells?
