Most effective mail marketing to find flippables

[Jonathan Roveto]

Hi all, I'm wanting to test the water with house flipping in my area. I already own 4 properties as long-term buy and holds and have a W-2 job, so I have sources of income. With this in mind, what are some effective ways of finding flippable houses that aren't exactly gut jobs? I've been thinking of mailers, but I don't know what gives the most bang for the buck (and the second I started researching, I got bombarded with those little yellow card mailer ads). I'm wary of foreclosures this early and would want to wait until I've flipped a house or 2 that I knew what its condition was before buying before buying a house I've only seen from the outside and bid on at the courthouse.
