quick introduction; 2 years ago i purchased my first property ($620k, 10%down, 4 units, $6100 gross/mo.) i have a single family flip that is wrapping up, expecting to make 20%/90k. i started a business to manage the rental property and got a credit line approval for flips. 

Thanks for taking the time to read my little introduction, I appreciate you spending the time to do it!

Ever since the introduction of ETFs and mutual funds it’s very easy to buy stocks without needing to be an expert.

The above paragraphs are an unintended side consequence of moving away from that.Note also I used "Spouses" b/c that is the convention.

I actually just made my new member introduction today, and it seems that we have similar interests in real estate investment vehicles in the form of multi-family properties. 

@Claude Beauregard, if Owner A wants Owner B's property and Owner B want's Owner A's property you could offer to make an introduction of the two. 

The day after closing, I gave the other three units my introduction letter and a Notice to Vacate by the end of July (everyone was on a month-to-month). 

Words of mouth can also bring you deals.Check out this post from J Scott where he explains how to analyze a real estate deal.https://www.biggerpockets.com/blog/2010-06-30-introduction-to-real-estate-analysis-investing

I have not done an introduction post yet so i figured since I am finally serious and now I'm going to be on here more Id go ahead and do an introduction post.

Although this last portion paragraph is contradictory to what I just stated with long term investing, this is just a personal choice of mine to get a 5-10% return, to more quickly build up my ability to put my next down-payment on a property.
