Why would you respond so harshly?

I know its a little harsh but its the truth.  

I really hate when people do that, this is considered a hazmat scenario and there are proper chemicals that are used for a reason with these types of situations.

The pilot holes for the lag bolts are typically 1/16-1/8 of an inch smaller than the diameter of the lag bolt making the mechanical base act as a sub flashing, and then there is also a chemical sealant (caulking, geo-cell, Henry's... depending on the installer) sandwiched between the roof decking/paper and the mechanical base.

I have a job in chemical industry (manager) and a good salary (90k a year).I started with buy & hold real estate in 2016.

That said there are laws to keep everyone in line, your state might be harsh on this stuff.If you got the tenant call within the last 24 hours and you have the fix scheduled to be in the next 2 business days, I "personally" think that's reasonable, but the law is what matters. if you're within your lease and within the law, I would tell them to hold tight.

At times, the odor was so strong you can smell it walking in the main entrance into the lobby.There's been some discussions here on remediating it with chemicals.

Perhaps I was harsh. 

I know that's harsh but its the law as well.in some states you get booted quickly and maybe the stress would bother her but if she is this far along in a foreclosure she has already dealt with stress.underhanded or secret after the fact deals be careful of.although post sale selling your redemption rights if your state has the right of redemption is very viable and toally legal.

I know that sounds harsh but that's how it is.
