Finding seller's lists

[Barbara Cordon]

Hi everyone. I am new to investing and would like to start finding motivated people who want to sell their home but are not listed on the MLS. I read about contacting people through letters who have lived in their home for 20 yrs and might want to sell. Also absentee owners and inherited properties that someone might not want. Where would i go about finding this information to compile by list. Any help would be greatly appreciated. Thanks!
