Understanding how much equity you can use from your home is crucial for your next property move.

Here's a clear guide to how banks assess usable equity in NZ.

What Is Usable Equity?

Understanding the difference between total and usable equity.

Usable equity is the portion of your home's value that a bank will let you borrow against. Want a simple breakdown? Sorted NZ explains the difference between equity and usable equity here.

Here's the standard breakdown:

Own home: You can usually borrow up to 80% of its value. These limits are based on Reserve Bank LVR rules, which can shift depending on market conditions.

Investment property: Up to 70% of the value

So the usable equity is:
(Lending % of value) − Current Mortgage

The key is understanding that usable equity is usually less than your total equity — but it's still a powerful tool.

A Simple Example

See how usable equity works in practice.

Let's say:

• Your home is worth $800,000

• Your mortgage is $400,000

Your usable equity would be:
$800,000 × 80% = $640,000 − $400,000 = $240,000

That's $240K you might be able to put to work.

Remember, this is just an example — your actual usable equity will depend on your specific situation and the bank's criteria.

What Can You Use Equity For?

Common ways to leverage your equity.

Most clients use usable equity for things like:

• Purchasing a rental/investment property

• Renovating or upgrading their home

• Starting or growing a business

Consolidating higher-interest debt

This is where good advice matters. Structuring things right from the start saves stress and interest later. You can also explore my mortgage services here to see how I help clients structure their next move.
