put out several dozen on a Friday all over the city at Friday night at every intersection and stop sign .I call this method “ flooding the block “

What are the most important things to think about and research when analyzing/looking at foreclosures with the intention of going the brrrr method route?

You would have to be able to negotiate a good discount and get the property under contract in order to wholesale and unless you can show proof of funds etc. agents will not work with you.That being said  here are some ways to find motivated sellers. you can purchase lists with different motivations like absentee owners, 60-90-120 days late on mortgage, pre-foreclosure, delinquent taxes, water cutoff, code violation, evictions, probate, divorce, etc. and mail or cold call.Other methods are driving for dollars, door knocking, wholesalers, craigslist, Realtors, FSBO sites, expired listings, put out bandit signs, billboards, newspapers, other offline publications.You can use pay per click/adwords, motivated seller website with SEO, facebook, Linkedin, Youtube, and other forms of online and social media marketing.

Im curious if anyone has used this method?

How much trouble could I get into if I use these methods to encourage him to vacate?
