@Nick B. (I have no idea how to actually make this link correctly), my feelings weren't hurt, but I am big on integrity and it did feel like a set up to question my integrity. If I misjudged that, you have my apologies.
I know a good number of members, both basic members and MF members. One guy who has become a friend of mine recently retired from his job (he was an engineer) because he earned enough cash flow from his 5 single family houses and several investments in MF deals. Most of my friends are either full time real estate investors now or are in between - they earn quite a bit of side income from their SF and MF deals (many at over 20% COC), but still work their jobs. Many SF deals that they purchased over the last few years particularly, return over 100% when they sell. I know several that are in MF that have had a 100% return when a refi is done.
Another friend joined a year ago as a basic member, didn't do anything, and a few months ago (May?), got back involved as a SF ("Challenge") member and closed on 2 SF purchases and is in contract on a 3rd.
I don't know how many people join, but never do the 2-day class. I also don't know how many join, do the 2-day class and then never do anything. Though I can't answer those questions, I'd imagine that the 80/20 rule probably applies, which seems like it would be normal. To be fair, how many join BP and don't do anything? How many join ANYTHING and fail to take full advantage? The people I know who have joined, learned the business model and applied it have been able to successfully purchase SF or MF and make a nice return. Though it's anecdotal and personal to my experience, success is completely dependent on your taking action than it is on whether the business model works or not.
About me personally, I have a small investment in a larger property and funds into two value play properties purchased this year that are just getting to a stabilized point (i.e. no distributions on those two have been made to the partnership), so clearly, there's not much cash flow at this point (my passive investment is cash-flowing at around 12% annualized, but I had a smaller investment, so they're not huge dollars). I should note for whoever is keeping track that while cash flow IS the ultimate goal, my net worth has increased by $375k+ (a 300%+ unrealized return) as a result of those MF investments (Increase of property value * my ownership % - original investment), so I'm happy with that.
Basically, Nick, you have no REI experience, but are doing an extraordinary amount of due diligence before you attend a free case study - where you get to meet actual members and ask them about their experiences, listen to members present their actual deals, and talk to LU mentors directly. Why don't you do that? What's holding you back? That's probably a better source of info on LU than posting on BP, frankly.
