Rental Property Within Asset Allocation

[Account Closed]

I do not want to turn this into a real estate vs. paper asset (stocks, bonds, etc) debate.  I am new to real estate investing and have the majority of my net worth in paper assets.  

For those of you who invest in paper assets (along with real estate), how do you calculate your rental properties into your overall asset allocation?  Or, do you keep things separate?  

Any advice would be greatly appreciated.
