Not the other way around.No offense those who are legal council have most problem finding a landlord.

If you then tell about his offense, it's a slippery slope-- will you be notifying neighbors of others bad behaviors like  misdemeanors too?   

@Grant Mone  No offense, but you sound like you are all over the place so a mentor probably couldn't help much yet.  

Out of all the anti-landlord measures that they were considering, this is the least offensive one.

If you don’t want to go that route, it’s their responsibility to get it to you in time.But, for your specific incident, I would respond with a ‘Please don’t take offense.

I take great offense to the idea that protecting myself *from* zillow is somehow "unethical".

No offense to you personally, but there are so many people out there trying to do this that fail or never get off the toilet, its not even funny.

Not to talk myself out of a job this is what I'd do:Get the demographic data from census.gov; population & population growth, employment and job growth, housing types and numbers.Check to see what data HUD has on housingCross check the above with the MT Dept. of Comerce and other state agenciesWith the size of the market in hand I would check the major (and any local) apartment ILSs apartments.com, forrent.com, Craigslist, etc. to get a sense of the tightness of the market.Then once you gotten the lay of the land, next survey the people on the front lines;Commercial brokersProperty Management CosAppraisersTitle companiesCity planning/building departmentAll the MLA members and apartment owners in town that you can track downThen of course you have to assemble it into something useful.

I am also quick to respond to tenants while in their lease so I am not sure why you would take offense to something you or any other landlord would do, if it required. 

His offense was 20 years ago and he did his time.
