How to tell + cash flow when property bought in cash?

[Vinh Nguyen]

Hello BP,

The following is hypothetical for simplicity:

I bought a single family home for $130k cash and spent extra $20k to fix. Hence, all in is $150k.

Rent income is $1600/ month.

Property tax is $1800/ yr and insurance is $800/ yr.

I understand if I had a mortgage on it and as long as the NOI(rent, expenses) surpasses the mortgage monthly payment, whatever remains is consider a positive cash flow.

How does one determine if there’s positive cash flow if the property was bought in full with cash?

How do I know if I’m making a profit?
