Using a skip tracing service may help you locate property owners as well.

While not mandatory, almost nobody in Wisconsin skips septic inspection, because the defects are potentially very expensive.

I landed my first couple of deals from skip tracing the returned letters from my mail campaigns.

But I am a big fan self sustainment, so I would not go do something unless the move will for sure return, so in your case, I would skip the entity and protection after first few flips, get your feet wet as soon as possible, then you are now playing money that you did less work. 

I've even had it pull vacant land up as a SFHI'm not really sure where to go from here because I could waist hundreds of dollars skip tracing and mailing with this data.Any suggestions?

Don't cut corners on rehab (windows) as it will make buyers nervous about where else things have been skipped.

If you want to hit people your competitors are giving up on though you could use a skip trace service to track down the correct info for that person. 

I am currently working a deal with a good friend and it's easy to get into a handshake deal and skip something in that situation.

Skip trace and call the owners.  

Skip trace them and call them up or him em with direct mail?
