Some can even detect chemical composition and contaminates, like lead.

@Yonah Weiss my degree is in Chemical Engineering.

It depends.Real Estate Investing is a great strategy for financial freedom but without formal education to get a good job that will allow you to have a substantial downpayment or buying real estate with cash, Investment may not be possible for that individual except you want to start with bird-dog (Wholesaling, Real Estate Investor Apprenticeship, Assistant etc).I have a Bachelor and Master's Degree in Chemical Engineering and I will say (with confidence) that it all worth it.Goodluck man!

I feel your pain.I’m a female and new to REI as a business.However, I’ve always handled contractors for my primary residence, and I’ve worked in several industries - industrial chemical sales, bartending/waitressing, and I’m now I am a chemist with a PhD.All that to tell you that male chauvinism is rampant anywhere you go.

Unfortunately, a lot of these people develop substance abuse problems and increase crime, violence and homelessness numbers.

My kids never saw me do any illegal substance, or have more than 2 drinks in the same week. 

Image over substance. 

I notice a tiny asterisk located next to the "rent" section of the comps and start searching through the entire packet to figure out what that is for.I finally find a small sentence that (in sum and substance) reads: if actual rents are unknown, it is up to the appraiser to determine the rent.

@Nathan ClaireThanks for the substance and silliness ;-)A modification/addition to the BRRR method I’m considering are ADU’s/Accessory Dwelling Units.

Programs such as Head Start, Substance Abuse Recovery, Public Transit, Worker ReTraining, and more.
