Good evening! I am somewhat new to real estate investing. I am fairly familiar with long term rental. My father had 38 long term rentals for almost 30 years and we spoke frequently of them. He sold them all before he passed. Now, I'm interested in starting my own real estate portfolio. I would like ideas on where to begin regarding type of rental I should start with (short term, long term). That will drive the answer to my immediate question, which boot camp should I enroll in first. In order to guide responses, I must say that I am an early retiree with a pension and ample investments so that I don't need monthly cash flow from rentals to live on. Any cash flow will likely be used to further the real estate portfolio. I already purchased a second home for cash which serves as a STR when we are not there and I'm looking to buy something in the next 12 months. So my first questions is, which BP bootcamp should I attend first. I'm tempted to try the BRRRR first because that's what I think I may do but I also think maybe the rookie one. Secondly, what strategy should I pursue in order to primarily build legacy wealth and that may give some cash flow along the way? I hope to stop at a half dozen or so buildings. Thank you in advance for any input you send.

Michael
