How much equity can fund the next purchase?

What the home would sell for today.

The balance still owed on this property, before any top-up.

Owner-occupied lending in this model stops at 80% of the home's value. An investment uses the investor loan-to-value cap instead, 65% or 70%.

Loan-to-value ratio is the loan as a share of the property value. This cap is used only when the property is an investment. An owner-occupied home stays at 80%.

How much of the next property would be borrowed. The rest has to come from the usable equity in the current home. At 65%, the equity has to cover a 35% deposit.
