Moving out of home to rent it out so i can save more in Australia

[Sam Telford]

hi everybody i was wondering if someone has some tips for me or can just tell me its a bad idear. I purchased my first home in Melbourne about 15 months ago my wife hates how small it is its a 3×1 but loves the location  so the plan is to move in to her parents house again so we can rent our house out and save more to extend i would like to know if people think its worthwhile or just sell and do i need to change my loan im also praying that my house price will go up so i can use my equity to start investing. Thank you
