Also, since it is in Denver County, you could have the neighbor fill out a noise complaint or call 311, and then the City of Denver inspector can send someone to talk to your tenant/send a letter and maybe that would get him to calm down.

I'm just now getting rehabs restarted and properties listed and am late with everyone, but they all know and understand why and are calm.

First calm down, it happens to everyone so dont feel bad and guess what, atleast if u messed up, u went out there and took steps to be successful.

If you receive an earful, stay calm and politely end the call by telling her that if or when she might like to negotiate, please feel free to get in-touch.  

@Lawrence Fiero, it is important to remember that, although mostly made up of hard working individuals, police are NOT attorneys...but often try to play one on the scene as a way to calm the situation.Contact your attorney and proceed as needed. 

so some may be gun shy, I might even offer a year long locked in lease at the current price  for the first year to try and keep everyone calm or even put stager terms in (6 months/1 year/18 months/2 years).

Pay a Guaranteed IRR of 10% and give them a small percentage of the back-end (do the waterfall structure as 90/10 for hurdle 1 and then 20/80 once you hit your guarantee-or-2.

Tenant2 barged into the house when Tenant1's dogs were not properly calmed down and the animals reacted to each other. 

I've found that people can turn around for you as longs you stay calm, relaxed, honest, and explain everything clearly to them.

Stay very calm and if they get angry, remind them patiently that they created the problem.
