He also went on to advise my Realtor that "it's illegal to be aware of this issue and not fix it and that she could lose her license if she did not advise me.

:my insurance never asked, i never asked either..i have tenants with pit bulls, no issues.This is because I just read that Michigan in one of two states (PA is the other) where they've made it illegal for insurance companies to discriminate against certain dog breeds.

I do beeline it is actually illegal to decline you from making an offer.

I have co-workers that commute from as far away as Crystal Lake (google it) or Kenosha, WI and get in via the express train.

Read the codes for the cities where you're putting these out and DON'T USE THEM if they're illegal. 

I talked to a Boynton Beach city worker who was removing signs.

I do know CA law says if you're doing something illegal you can give a 3 day notice but the landlord isn't on board with that.  

MA is very tenant friendly so make sure you don't just put in stuff that seems like common sense, about 90% of the time that is probably illegal

but is this illegal or anything?

Busted pipes, workers not showing up, lost a tenant or two after wasting plenty of time to get them in, then two full months of doing mandatory classes, getting my LLC's approved, getting the inspector happy, etc...It's a bit of a headache, but Atlanta AHA is pretty great.
