I came along bigger pockets and realized that this is a community that I should be involved in i currently have the pro package to get the most out of this experience. 

Stand Alone Umbrella companies or go with one umbrella company for all the package.

I went to one club but they just tried to sell $900 package to a house flipping boot camp?

Make it easy for an underwriter to say yes, by sending in a FULL package the first time.

It seems that you have to purchase some sort of package from some third party websites.

Support is completely free unlike Yardi where you have so much support included and need to buy additional packages.

The major carriers will get you a well rounded 'package policy' so that you are covered for property and liability.  

@Brett Thomas, yes, I expect the whole building/land package would be appraised.

I have recently come across a duplex I want to make an offer on and the sellers agent mentioned the owner has another duplex two doors down he would be willing to sell as well in a package deal (likely at a discount to get rid of both).

So, you find a deal and package it nicely with exec. summary, and other info.
