One was a grounding rod for the electrical panels which caused my insurance to cancel since it was a fire hazard.

I can't stop laughing at your title to this post.  1000 houses? 

It's title Triumphs and Train wrecks of REI in Hawaii.   

Friends Title is Attorney owned and works with investors.

isn't that covered by a warranty or insurance?

For the latter, a great home owners policy with + a large umbrella insurance should mitigate it.

Its guaranteed by the insurance so if they mess it up you might get a free update.

So the monthly rent payments received will not cover mortgage payments, insurance, property taxes, repairs, maintenance, etc, and to avoid default the owner will be required to “come out of pocket” for the negative difference. 

Just as the title suggest, apart from having your license and certifications...what do you look for in an RAL?

Yes, even though mine have names for accounting and titling purposes I'll usually use addresses to a point.
