Money management during building period

[Alex Hardwick]

Hello,

   I am new to this community and to real estate investing. 

   The way I handle my personal finances right now is essentially the bucket method. I spend 25% of my paycheck and put the other 75% away. That money fills my bills/emergency fund (3mos expenses) then spills over into my savings bucket.

   Assuming I continue to work while building my rental portfolio would this be a good method to use to manage the net cashflow from my properties?

I was thinking... 3mos expenses (bills vacancy) -> 6mos gross income (maintenance/emergency) -> 6mos gross income (new property aquisition) -> free and clear profit.
