Get Reserves? Or Buy another property?

[Yaron Horsky]

Hey all,
Would love to hear your take on this one.

In my current situation, I have the money for a down payment and I can get financing and buy another property(this one will be number 3).

Now, if I buy another property, I will have almost nothing in reserves, meaning that in a time of a horrible situation or whatever, I will not have a cushion to rely on.  

So, the question is this, should I wait till I have some kind of reserve if so-How much do you think that will be? (I know it's kind of a general question but try and give examples of your own experience, it will help me modify it to my situation). 
Or, Should I buy the third property now? 

Thanks
Yaron.
