Sell your home, or keep it?

Compare deposit funding for your next purchase. Equity does not automatically mean you can borrow more.

Selling or keeping your current home

Selling can release cash after the loan and sale costs. Keeping the property may require borrowing against equity to fund the next deposit, increasing total debt.

Example and common question

Illustrative example: A $900,000 property with a $450,000 loan and $25,000 sale costs releases $425,000 before other adjustments. Add $50,000 savings and reserve $20,000 for buying costs and a buffer to leave $455,000.

Can I borrow all the equity shown?

No. The loan-to-value ratio is a scenario you enter. Lender valuation, rental income, repayments and approval criteria determine usable borrowing.

Keeping it needs a full lending review

The keep scenario assumes you can borrow against equity to cover the deposit. It also requires approval for the new-home loan and assessment of total debt, rental income, cash flow and both properties.

How this estimate works

Sell: sale price minus current mortgage and selling costs, plus cash, less buying costs and buffer. Negative available deposit means additional cash is needed. New borrowing uses a non-negative available deposit. Potential equity borrowing is current value × entered LVR minus mortgage, floored at zero.

Keep: the deposit target and costs are funded from available cash, then equity borrowing. Total debt includes current debt, equity funding needed and the new-home loan. If the funding gap is positive this plan is not fully funded at the chosen assumptions. It does not assess serviceability, bank valuation, equity policy, legal structure or tax. Any current-lender break costs and cashback repayment should be added to the applicable costs.
