Short answer: Loan to Value Ratio. Loan divided by house price. Below 80% is safe. Above 80% needs special approval.
LVR stands for Loan to Value Ratio. It is the loan amount divided by the house price, as a percentage. If you buy a $500,000 house with a $400,000 loan, your LVR is 80%. Banks care because high LVR means high risk. Below 80% is considered safe. Above 80% needs special approval.
House Price: $500,000
Deposit: $100,000
Loan: $400,000
Lvr: 80%
Meaning: Standard lending, no special approval needed
