Done properly it's a powerful tool.Think about this, you don’t know what LEGAL forms you need, let alone what they are FOR and how to FILL THEM OUT.

Lastly, be a good landlord and build a certain relationship with your tenants by ensuring that you address all issues and concerns in a timely manner.

This will identify major issues with the property and give you an idea of any large capital expenditures needed and maybe give you some negotiation leverage.

To address this maintenance issue, I sent out a reputed garage door company to look at it. 

I'm only bringing this up because you mention 1) rent is always paid on time; 2) neighbors have no issues; 3) The tenant's are hardly there (which means less property wear and tear) and 4) I will also assume becuase of the first 3 here, that your property is also being cared for...... seems like picture perfect Tenants.... 

I’ve also had issues do a cash out on my two properties.

We just don't want our clients to face issues if they were ever audited and I'm giving you the same advice! 

Doing the due diligence on rental rates wont be an issue for me but I’m not a developer.

If there's ANY concern about the foundation or structural integrity, I call in a foundation pro, or I walk (foundation/structural issues are usually my one total deal-breaker).

Rent Control is a two sided issue.
