I ask tenants to email issues because it provides a record and forces them to provide specifics. 

I am based in Greater Philadelphia region and worked on a deal the owner sold 75K sq ft self storage and kept 20K sq ft of contractor specific self storage.

@Ayyoub Reza   There are a number of places to get agreements but make sure you get one that is current and state specific (here, legal zoom, a lawyer, real estate association ) Read your HOA bylaws what does it require to be included.

Asking these questions directly to the specific parties involved would be a more efficient use of time.

We have a specific lease used in the city of Chicago that changes every year to maintain compliance with our ordinance and local laws. 

I was interested by your post and wasn't sure exactly how to respond since I wasn't sure what specifically you were asking.  

Be specific about what you're doing there in case you have an issue.

These conferences are typically in the family office space but some are industry specific.

Pick one that is commenting on your specific situation and DM them.

I'd specifically ask why it is being treated as a third party sale since the LLCs members are you and your wife.
