Capex wipes out cash flow for a year?

[Bill Ward]

So long question short, my rental property averages about $150 a month cash flow after regular maintenance expenses and minor repairs. But for a capex expense, my next one being a bath tub replacement or replacing the carpet with LVP. Is it normal that a minor $3k expense such as those would wipe out my year's worth of cash flow, and leave me in the red on paper? Justified by the fact it's not a normal yearly expense, Or does my rental just suck? Mortgage PITI is $900, rent is $1300. Mortgage is high as it's year 4 of a 15 year mortgage.

Thanks,

Bill
