Cashflow and 50% rule

[Austin James]

Good Afternoon!

I am looking at a potential SFH rental but am trying to figure out the 50% rule. If the rental could potentially cashflow $150 to $250 is it bad the 50% rule is in the negatives at $ -50 to $ -100?

I used the BP calculator and set the variable expenses to 5% besides management. 

House costs $192000 and I am using a VA loan.
