Make sure to review the current owner's lease agreement with that tenant to confirm there is a security deposit and see what type of language they include regarding the security deposit.

@Tim Johnson I just notate this fact in their lease agreement and on their rent roll in my software program.

I will have to confirm this.

As an example a software "tech engineer" can write code for Google, Amazon, Tesla, Salesforce.com, airBnB, Uber or any other countless companies. 

Anyone ever confirm any meetup in the area?
