I have approx 0K cash and I want to invest in housing and hopefully build a large portfolio one day (on the very far horizon haha). Does anyone know the best way to build a portfolio with this money? For example, use it as deposits for three houses that all produce rent from day one with some input to the loan from me? Or should I use all of the money to buy one more expensive house and later use the equity in that property to leverage finance for other properties (once it appreciates)? Or, or, or…………….there are so many ideas and so few answers in my head.

Any genuine advice would be greatly appreciated.
Thanks in advance.
