How much money should I have after down payment?

[Johnny Constantino]

Hello all,

I am looking to purchase a multi-family apartment building, and I am wondering how much cash I should have put aside for closing costs, and any other issues that may pop up. I want to ensure I will have enough capital to fund my deal, and keep it operating if worst case scenarios occur. Obviously the size of the building matters, but we can talk percentages. Or use an example of a $2 million dollar property with 500k down. 

Thank you
