Property Investing: ROI Tax Question

[Daniel Mendez]

Good evening BP,

Out of curiosity, how much should one save off of the cash flow that one could make off every unit?

For example, say I bought a home and it cash flows $400 a month after all expenses. Am I free to spend that money? Or should I save a portion of that money just in case Uncle Sam’s wants his money when I do my tax returns?

Thank you for the guidance
