Here’s why I’m asking: I have an Excel model that analyzes deals for a specific region.

I'd try for the $1600 at first see how they react then readjust accordingly if need be.

I am not referring to PR specifically.  

I understand I cannot legally require them to respond, unless the notice specifically requires it, like for instance, a notice of entry, but it's making it difficult to manage the property, and I'm not sure how to proceed.

You're buying a specific property, in a specific location, in a specific condition, subject to local rules and regulations.

Rent control laws are market specific.

Are there specific cities or states where this lobbying is already having an impact?

@Cody Ford Without having specific expenses and the 4th rent amount I can’t say for sure if I would pull the trigger on this property.

As for Alexandria specifically in terms of regulations don't take advice from a public forum - look up the laws yourself and make sure you understand them.

Sounds like you need to learn how to work with people given how you are reacting and responding to everyone on here.
