Have plenty of ventilation or a chemical filter mask while using both the clove and the sealer.

If all goes to hell, I still have a 9-5 that pays well and a degree in chemical engineering.  

I'm absolutely not experienced, nor a professional in this, but I have heard rumors that due to the chemicals, it could be enough to condemn or make the property inhabitable.  

I currently work a full-time day job as a chemical engineer (shout out to Andrew Cushman from BP podcast episode 170), but I'm planning to eventually transition into real estate investing full time.Short-term, I'm interested in spec home building, as well as fix-and-flips, but eventually would like to change over to a buy-and-hold strategy involving multi-family properties for the long term.

Payments are just over $1,300/month. pool service, $100 projected( have done the chemicals initially myself), landscaping free, all desert scaping, not much work to do.

I had mine done on my recent rehab (granted it was really bad) it was chemically cleaned it cost 450.

Chemical are temporary solutions.

It there a clause I could add in the lease agreement, to not use chemicals, and that we are not responsible for whatever? 

I currently work a traditional 9-5 for a chemical company (I have a computer science/software background.), and work part time for a realtor/real estate investor.

Warranty fine print says "chemical deposits" void coverage.
