When to stop saving for Maintenance, repairs, CapEx, etc.

[Matt T.]

Good Afternoon, 

I am looking for some opinions on when one should stop saving for the "expense and vacancy" related fees? At some point, the funds saved should outweigh the risk involved and would probably be better suited for further investments. 

I'm planning on saving for 3-6 month of vacancy, however, I see repairs, maintenance and CapEx being a little more volatile.

Do you take the highest/worst case repair and make that your goal?

Thanks in advance for your input.
