I built a list and skip traced 750 addresses.

Better off using a mix of like mapdriven with a good CRM and skip trace company and separate mailer company.

I went with my gut and dodged a bullet here since we skipped buying the property.

There are several skip-tracing companies out there.

Some may skip trace for you and giving you calling and text message integration.One thought is in my experience probably 80% of the properties don't go to sale, the first date they are posted. 

I would agree that the likelihood of having any lawsuit go against you for more than a million is very small, but the coverage benefit is just to cheap to skip.  

@Mary Lopez I recommend most investors skip multifamily properties that don't qualify for agency (Fannie/Freddie) or HUD financing. 

I definitely must have skipped a few chapters.

(Like a 1031) skipping all the middlemen. 

Next you use whatever skip tracing system you like.
