I spray the leaves with Round-up on a warm dry day (normally wouldn't use it, but sometimes chemicals are your friend), then plan to go out in a day or two and remove as much as possible.  

We have a dog and cat that have brought fleas into the house and instead of using harsh chemicals, we spray this on the animals and floor, furniture and carpet.

We remodeled the house, fixed it up, had it treated for termites, and then made it into one of my best rentals...but of course the story doesn't end there.We treated the wood but the chemical today used isn't like it was years ago.

Train derailed 3 miles away carrying some hazardous chemical etc.

An uninsured worker that gets hurt on your property or a contractor digging up a gas line with a back hoe or disposing of toxic chemicals like paint or solvents into an environmentally sensitive area can result in a huge liability that can easily exceed the value of the property.

I also just graduated from Pitt in April 2017 with a bachelors in chemical engineering... sounds like we were in the same graduating class, small world and H2P!

I’m interested in buy and hold rentals, specifically duplexes and triplexes, and would very much like to start using the BRRRR strategy.Right now I work full time as a Chemical Engineer, but I’d love to build a real estate portfolio that would allow me ditch the 9-5 if I decided I wanted to.

They have a high likelihood of containing micro-organisms or chemicals.
