The violent dogs are victims of violent owners or victims of forced violent lifestyles.

And give them appropriate notice, preferably at least 48 hours - and I say this from the point of view of someone who is now a tenant, who lives a cluttery lifestyle LOL. 

It's a lifestyle choice.  

Glad to hear you're giving tenants options for how to pay their rent, as it allows them to tailor the method of payment to coincide with their lifestyle.

They also help 'sell' the place to the potential new tenant, talking about the lifestyle or conveniences that comes with the house, and it seems to help minimize the vacancy period.Does anyone else do this?

Many small mom and pop type investors give up the opportunity to make a ton of money and have a wonderful free come and and lifestyle simply because they never see the importance of learning to be a skilled landlord.

Remember your going after a lifestyle kind of living not a never ending nightmare which this seem to be.

Any proven record that it was in the past and not current lifestyle?

I'm a property manager in Seattle, and made the conscious decision to charge a flat % instead of applying fees for every service.

I'm playing with the idea of embracing the transient life style of the young enlisted guys and putting each on an individual lease that has a higher rent that if it were split.
