@Jim K.Firstly Roundup glyphosate poses environmental toxicity and there are some studies that indicate that it has carcinogens.Secondly, I may end up inviting a fight with my neighbor.Lastly as indicated I am really vexed with this new tenant with her 10,000 complaints ever since she moved in 7 days back,for example when she sees a one off centipede outside her door in the backyard she immediately asks me to call an exterminator....so the list goes on and on..I wouldn't say its contempt but it's a PITA to deal with such tenants especially after a great tenant that left you.

They are now reviewing a lengthy phase 1 and 2 environmental report.

Also you will want to make sure to check for or get a phase one environmental study if there has been equipment and fuels used or stored on the property.  

I also found out that the back taxes were inflated by about $1,750 due to an environmental assessment that had been added but never completed.
