Most of my direct/indirect family do. No strategy, simply high income earners with savings. The OTP unit in Melbourne CBD type stuff. Learnt everything I know about IP from outside the family.
Through family history there has been an investor or two, though I found out AFTER I started investing. Paternal-Uncle seems to be in large development in Iran. Maternal-Great-Grandad was greatly successful in Peru, though all that is left now is a few industrial and resi property in a trust worth a few million (13 kids and in-fighting does that). Notable exception, one of his kids started the hot-spring hotel industry in a now-popular-holiday city in Italy (I visited them about 3 years ago).
I grew up around those with ‘rich-uncles’, who owned landmark sites around Australia (they are large developers). They always use to point them out ‘my uncle owns that’. I always thought to myself, wait… do I want to point it out, or do I want to BE the rich uncle.
I have dragged some friends along for the ride, some now up to 2 properties. Though more them asking me if something is a good buy, as oppose to understanding why. Also dad kinda-gets what I’m trying to do, and is now very supportive. Did a JV with him on my last purchase. Uncle and a few family friends have also approached me to JV. Looking at development sites in the near future.
