That said, as an experienced flipper who heavily relied upon a network of wholesalers I can whole heartedly endorse this approach of an equilibrium in buyers to deals, NOT the "let's blast each deal to the entire universe", which is no kind of relation, it's an annoyance, one that has us flippers looking for a replacement wholesaler in like kind. 

Medical Payments (covers medical costs of an accident on the property)There are many endorsements available and you should discuss the coverage with a qualified Independent Agent (they represent multiple companies).An Umbrella policy provides an Liability Limit that can provide coverage if a claim exhausts the limits of your Homeowners, Auto, Boat, motorcycle, etc. policies.   

Some companies offer it as an endorsement to the policy. 

@Nathan Gesner is right on the money with his explanations of how and why the Additional Interest & Additional Insured endorsement is used. 

And while I had the businesses in LLC's, my attorney and insurance agent insisted that I get an endorsement in the LLC policy that covers me personally and an umbrella in addition on top.Furthermore, I bought an active business in an S Corp, through an LLC, and the owner was sued for $3 million.

Two ringing endorsements if I ever saw one.

I would either endorse the check to my LLC or deposit it into my account and immediately write a check to my LLC.

Are you acutally meaning that you sell your notes with the   " With Recourse endorsement on the reverse side of the note"  My Dad did that in the 60 's and 70's in CA.Did not know if that was still a common practice. 

I ask tenants to mail check or money orders to my po box for rent payments so usually don't need receipt....they can access endorsed check through their bank.I dont want to run around picking up cash both for convenience and safety...congrats on your rental!

Beware of first time posters making endorsements of any real estate course or system !
