Cashflow

The net money flow from your investment property

3 min readUpdated December 2024

Cashflow is the actual money flowing in and out of your investment property each month or year. It's the difference between what you collect in rent and what you pay in expenses.

The Formula

Cashflow = Income - Expenses

Income:

  • • Rental income
  • • Tax savings (from AfA and interest deductions)

Expenses:

  • • Mortgage interest
  • • Mortgage principal repayment
  • • Property management fees
  • • Maintenance and repairs
  • • Property tax
  • • Insurance

Positive vs. Negative Cashflow

Positive cashflow: Your property generates more income than expenses. You pocket money each month.

Negative cashflow: Your expenses exceed your income. You pay out of pocket each month.

Is Negative Cashflow Always Bad?

Not necessarily!

Many successful investors accept negative cashflow early on if:

  • • They can afford it from their salary
  • • The property is appreciating in value
  • • The mortgage will be paid down over time
  • • Rents will likely increase in the future

Think of it like a monthly investment into a fund—except it's real estate that you own.
