Need Help with 1% rule in a real life example

[Barrett D Mize]

Thanks in advance! I am super a newb.

I have found a duplex for $230k. If I bought it I would put 20% down. I could rent both sides sides for $1000.

That does not meet the 1% rule correct?

$2000/$230000 = .9%

The reason I’m confused is that the mortgage would be about $1000 a month and with other expenses (taxes, maintenance etc.) being around $700 a month.

Expenses total: $1700 a month

I am cash flow positive by $300 each month, which seems like I should go for it… but the 1% rule seems like I should not go for it.

what am I missing? Please help me figure out if I’m wrong on any part of this. Maybe the 1% rule does not apply in this instance?
