Is Mareketing for non-MLS houses necessary?

[Jason Genovese]

Hello,

I have been buying my houses off the MLS, auction web sites, and other wholesalers. I wanted to receive some opinions if it is worth investing into marketing campaigns to find motivated sellers that are not listed on the MLS?

The local REI clubs I visit in my local area (st. louis) all seem to recommend some sort of marketing to find off MLS deals (Probates, Absentee owners, etc).

Thanks
