Rental Property Investment

[Lakshmi Nikitha Duggirala]

Hi, I was analyzing a potential real estate property. The ROI is anywhere from 15-22% depending on how low I can get the purchase price. Cash flow is ~$350 a monthly but it doesn't meet the 2% rule (it's at 1.50%). So I wanted to ask how crucial is this rule and would you suggest looking at something else or does this still seem like a sound investment?
