Having trouble understanding where the profit is

[Richard Hoyte]

Where I lack understanding is at what point do you start making money for example you buy a duplex lets say it was 300k the monthly mortgage is 2,500 each renter pays 1,500 thatd 500 cash flow which is I guess “profit “ but as the landlord you're responsible for major repairs such as but not limited to roofs, plumbing issues, electrical issues that all can be expensive you would have to have money saved so that 500 cash flow is profit but wouldnt it just have to sit in a bank account?
