Financially all in or keep some in the bank

[Jack Young]

I'm looking for opinions on finding a balance between keeping some money in the bank or paying off personal debt, low interest but freeing a lot of time and working as a safety net or a nest egg for the perfect deal to snap up or investing more aggressively trying to build a bigger portfolio but undoubtedly in my case sacrificing time. My goal is to sell a rental around this time next year and pay off my mortgage, allowing me to have time to devote to family and real estate in a much more serious way also having the ability to pull the trigger as soon as I see something I like. I've read a lot about both, but numbers aside, time to put proper focus on one or the other is more important in many cases. What advice do you have?
