For my personal education, which one insurance should I have?

They take a lot of nurturing, educating and patience.

The goal here is to align with investors and educate them about the benefits of long-term strategies.

If that leads to a more structured and education based meeting, then that is great - if it remains just a place to gather and bounce ideas and network, that's great too.

A lot of agents don't want to have to educate someone who is broke and has dreams of financial freedom through real estate just to find out you can't buy.

To make the most of your time here, explore the forums, listen to the BiggerPockets podcast, and take advantage of the educational resources and blog posts.

A LAIC will be held responsible and liable for any issue at a property if the owner of the property refuses to fulfil their duties.

So is education/classes. 

It sounds like you are off to a great start already especially by educating yourself! 

If you are able to manage it yourself, I think you will get a lot of very helpful education in real estate by spending a least a year or two doing that.You'll be able to work with property managers a lot better if you've done the work yourself for a bit, and it also helps to get familiar with the various laws and regulations you have to comply with as the owner, even if you do have a property manager in place (e.g., the new RI rental registry and associated lead paint inspections/certificates).It's up to you whether you're able to do it, but I think you'll get a lot out of the experience if you can try it for a year or two.
