2% Rule

[Chayden Young]

Hi, I've been reading "The Book On Rental Property" and I know I understand the math for the 2% rule but the book is throwing me off. He says "you buy a house for $300,000 and rent is $2,000 per month. So this property meets the 1.5% rule but not the 2%." Can someone please help or explain it a little better. Because 1.5% of $300,000 is $4,500. 

Thanks!
