My sister has turned 18 and got her first full time job. She's eager to get into the property market and has a small deposit - but not enough to move forward on her own. I've been exploring ways that we could purchase something together. My thoughts are to get something under the $250k mark in need of a good renovation. (My dad helped me renovate my first- and he's promised to do the same for her). If we do invest together I want something that will end up positive geared - I don't want to put an 18yo in a position where they can't travel and live a life because they're bleeding cashflow. I also need it to actually make sense for me and my own portfolio. I was thinking maybe we find something subdividable and sell the back off to put our deposits back into our pockets. It would be treated like a proper business relationship with a JV document in place. Has anyone got any experience/ advice when investing with a young person?
