You can borrow against other property to purchase management rights.
The Banks will consider up to 80% of the market value of your property less any current debt.
eg: your house is worth $800,000 with a debt of $200,000.
$800,000 x 80% = $640,000
Less current debt $200,000
Available equity $440,000
(This amount would allow you to consider a business around $1.2M subject to the income being sufficient to service loans, taxes and general living.)
Whenever you borrow against property to fund the purchase of management rights, it can create a strain on your cash flow as the majority of your income goes towards loan repayments.
