@Mark Mynhier  not sure about CA.. but in Oregon to be a licensed contractor you need a 20 to 50K bond and insurance.. the bond may allow some recovery.. plus most contractors don't want complaints filed against them..

If I pay cash and compare that amount of money to what I have invested in bonds and stocks it needs to return 6-7%.

I'm also interested in learning about private placement notes and bonds - and learning more about the topic "Syndication."

I have been investing in stocks, bonds, etc since I was in college but never notes.
