Is there any easy way to get Months of Inventory by zip code calculated for my area without Redfin and without bugging my agent? 

@Lethorn Irving II also check to see if there are updated codes particulaly fire for you to comply with if you do this.

It is like arguing with building inspectors about code.

The rules are very strict and need to be followed for them to work.

That being said, she can get more depending on the zip code.  

Does anyone know if it's possible to look up the evictions that have occurred in a given city or zip code for a specified time period?

It could be an illegal duplex, meaning someone converted a single-family without permission and/or in violation of code.

Since my units are perfectly located for the academic and not as perfectly located for others, I've never been able to find non-academic tenants willing to pay top dollar for the location.For one of my units, I'm strict about begin and end dates (Sep - Dec, Jan - May, Jun - Aug) and I rarely have even a day vacancy.

Smart locks are good for this, until they aren't : ) But if the tenant has wifi you can do smartlocks and give codes to contractors that are good for X hours then expire.  

You cannot use older properties as a model as they are grandfathered and do not have to abide by the new code.
