We got it done but I had to step in and go around my agent on numerous occasions.

I'm now looking to hit those this week and the next, but am drawing a blank on how to find out who is in charge of the properties?

You've got Lifestyles Unlimited, Brad Sumrok, Michael Blank, Think Multifamily, Total Wealth Academy, and probably several others that have big conference where you can meet dozens of syndicators.   

On occasion a buyer will hire an agent and expect to get paid, we negotiate that base don how the buyer found my property.

Also try out the Old Capital Podcast (they are Dallas based apartment lenders) and Michael Blank has some good content.Finally I don't have any experience with them but I know there are some investor education and networking groups like Lifestyles Unlimited in the Texas area I hear mentioned on podcasts.

Start by reading @Michael Blank Financial Freedom with Real Estate.

I have been making offers for multi-family, and in some cases I have been receiving fairly quick responses but in other cases the sellers go blank.

I have an inspector that I use on occasion, because he's a real nitpicker on stuff, and if he didn't find it it probably doesn't exist. 

Or would we just print off a template and fill the blanks? 

On occasion, the current use of the property isn’t the most worthwhile or being used to its full potential.Take this project for example, originally a mismanaged duplex; we decided the best plan of action would be to turn it into a five-bedroom three bath SFH to allow for maximum rental income.
