Lawyers warning clients about yellowletters?!

[K.D Neider]

So today I had some time on my hands and went driving for dollars. I came up with 25 properties out of which 20 were use full leads. Anyway, for the properties that listed the owners as having the same address I did some digging and looked for phone numbers of the owner. I got in contact with one lady who was a relative of the owner and she tells me that the familys Lawyer warned them about the yellowletters and the receiving sudden contact from investors.  My question is, is this common?  And why?
