Take some pictures of the house and the condition it is in.

The time saved on seeing that bigger picture is worth it to me.

I really like the fact that you made a profile with a picture first before your first post.

I keep scans or pictures of all of all letters I send this way including the letter as readable before it goes into the envelope which includes the tracking number written on the letter, plus the filled out certified mail paper and the envelop after its addressed. 

Take 100’s of pictures even if small stuff.  

4) What do their places look like, how do they feature their professional pictures?

Add a picture you've personally taken of the property if you use postcards.

Lots of wrong/bad numbers and high email bounce rate.

Quote from @Rud Sev: Hello,I am new to the world of syndication (LP investor) and want to understand how taxes at a high level for syndication as LP before asking individual specific questions to my CPA.Notably, I want to understand how preferred returns/cash flows are taxed, if at all, until the amount invested has been returned.

I did that (posted the notice on the screen door and took pictures), however don't know if it's legally served.
