I think going to investment clubs and being “in the market” is more helpful than many boot camps. They’re all teaching the same things, but by networking, you really learn from other investors and get a better idea of what works best in your market.
As far as having a license, there’s been a lot of discussion on that topic in previous posts, so it would be helpful to do a search of forum topics.
rather than spend 5k on bootcamps, its better to put that towards buying investment property. i spent first 10k on 2 properties that ended up netting me just over 200k over 3 years. imagine if i had spent that on bootcamps, i’d still be broke.
