On this topic
Cash flow is money in minus money out over a period of time. Positive cash flow means more arrived than left. It is the number that determines whether a business, a rental, or a household survives a bad month.
Cash Flow vs Profit
Profit is an accounting figure; cash flow is what is actually in the account. A profitable business can fail because invoices are paid in 60 days while rent is due in 30.
Cash Flow in a Rental
Rent minus mortgage, taxes, insurance, vacancy, maintenance, and management. Anything left is cash flow, and anything negative comes out of your pocket every month.
Personal Cash Flow
Take-home income minus all spending. Track it for one month and most people discover 10–15% of their income they cannot account for.
How to Improve It
Raise prices or income, cut recurring expenses, shorten payment terms, and delay non-urgent purchases. Recurring costs are where the biggest wins hide.

No. Profit includes non-cash items and can count revenue you have not been paid yet. Cash flow only counts money that actually moved.
