Not so far...but, I am in an urban environment.

I want my kids to grow up in an environment where they learn that it really is possible to make things happen if they work hard and put their mind to use.

Address what is attracting the ants, such as the exposed cat food and cleanliness of the environment. 

While my full time position pays the bills, I am quite disenchanted with the high-stress rat race environment and would like to increase my income.

This industry requires ongoing education because the environment is always changing.

I have a few that receive discounts for services like @James Wise mentions.In an environment of ever increasing utility costs and rising taxes, sometimes the best I can do is raise a good tenants' rent by, say, $25, then include an addendum with that rent raise that 'reduces' their rent by the same amount for continuing to pay on-time and in-full with no neighbor complaints.  

I imagine rents would also be rising in that environment, so it might be a bit of a wash, but really unsure.

My question is "What are the rights of the other tenants with seniority that were already living in the home because it was a pet free environment?

State legislatures feared this would prevent people from starting new businesses in their state for fear they may lose their own own personal assets in the ever increasing litigious environment.
