You will have higher premiums if the property is not operating within a formalized 503c nonprofit entity. 

I definitely would want the mail to go to the correct place.If someone wanted to sue you, the fact that you ignored changing your address would be a good argument that you are not maintaining corporate formalities, potentially having the protections of your LLC ignored.Most states have annual filing requirements for the LLCs so that would be a good time to update it.  

I manage each property personally, which has provided me valuable experience but also highlighted the need for a more formal structure as I plan to expand my portfolio.My PlanI'm looking to establish a Wyoming Holding LLC that will be taxed as a partnership.

@Ricardo Polanco barely qualifies as a lease:(This "lease" leaves you open for a lot of abuse and we don't suggest trying to terminate it on your own - or you may get an EXPENSIVE lesson from a judge!

I just don't have a big market, so it's tough to find something like this particular property as evidence.I was thinking of something more general, like a formal study of various markets, but I haven't found anything except general articles or blogs.

The items you mention MOSTLY qualify.

If one is going to spend money on training learning how to present qualify and CLOSE is the skill agents need.
