Better way to find an investment property

[Tommy Adeoye]

I spent about 5 hours looking for properties on rental.com, zillow and redfin, My niche is multifamily and I have decided to kick off with house hack. I looked up the midwest - Kansas city, MO, St. Louis MO, Nashville, TN and went as far as Austin, TX. The rental calculator on BP keeps giving me a negative coc %. I'm either calculating incorrectly or I have to dig deep to find them. I am thinking about investing in direct mailing but I'm too green to handle those. Any Ideas?
