An example in Auckland
$800,000 house price
$80,000 deposit per homie required (based on 20% deposit, $160,000)
$385.75 per week mortgage repayment for each homie (based on 4.79% per annum over 30 years)
Compared to $520.00 per week for the average Auckland rental property you could save $134.25 a week, or could put this towards paying off your principal loan faster and gaining more equity.
Additionally you will be getting on the property ladder, having the security of owning your own home, taking advantage of any capital gains, and no more rental inspections!
