Lenders typically prefer a deposit of at least 20% for NDIS loans to avoid Lenders Mortgage Insurance (LMI). However, some lenders might offer a Loan-to-Value Ratio (LVR) of up to 90%, depending on your financial circumstances and the property's value. A larger deposit can boost your chances of approval and help you access more favourable loan terms by reducing the financial risk for both you and the lender.
