Usable equity
Start with a lender-supported valuation, subtract the existing mortgage and allow for the lender’s maximum loan-to-value ratio. Available equity can be lower than the simple market value less debt calculation.

Moving from one home to the next creates more moving parts than your first purchase. Chris Berry helps Victorian home owners estimate usable equity, compare suitable loans from more than 40 lenders and coordinate the finance around their sale and purchase.

The short answer
A mortgage broker can model how much of your current property's equity may be available, estimate the debt left after your sale, compare buy-first and sell-first pathways, and arrange a suitable ongoing or bridging loan. The aim is to know your realistic purchase range before you commit.
Build the plan first
Your target purchase price is only one part of the plan. A useful upgrader assessment also tests the equity you can access, the temporary peak debt and the loan you expect to keep after selling.
Start with a lender-supported valuation, subtract the existing mortgage and allow for the lender’s maximum loan-to-value ratio. Available equity can be lower than the simple market value less debt calculation.
Model a realistic sale price, then allow for the mortgage payout, agent fees, marketing, conveyancing and other selling costs.
If you buy before selling, peak debt can include the current mortgage, the new purchase and eligible buying costs until the sale settles.
Estimate the ongoing home loan after your sale proceeds reduce the temporary debt. This is the repayment that needs to fit your longer-term budget.
Compare the pathways
Neither sequence is automatically better. The right option depends on serviceability, equity, the properties involved and how much timing and price risk you are comfortable carrying.
How it works
Map your current mortgage, income, property value and likely selling costs.
Compare sell-first, simultaneous-settlement and buy-first funding pathways.
Seek pre-approval and coordinate finance milestones with your conveyancer and agents.
Common questions
Usable equity depends on the lender’s valuation, your mortgage balance, the proposed loan-to-value ratio and lending criteria. It is not always the full difference between your estimated sale price and current loan.
Potentially. Options may include bridging finance, servicing both properties, negotiating a subject-to-sale condition or coordinating longer and shorter settlements. Finance approval and legal advice should be obtained before signing.
You still need to fund the purchase deposit and settlement costs. Depending on your circumstances, the source could be savings, accessible equity, sale proceeds or an approved short-term arrangement.
It may be possible if your borrowing capacity, equity and cash flow support both properties. Loan purpose and structure should be considered carefully, and tax advice should come from a qualified tax professional.
Ideally before listing your current property or making offers. Early modelling gives you time to check valuations, borrowing capacity, loan structure and the settlement sequence.
