Affiliate marketing, gurus and eCommerce are three of the biggest money making scams out there.

Anyone promising you guaranteed cash out the gate is probably scamming you.

I've seen a lot of scams in the space these days on FB.

In my opinion you really don't need a mentor, I used to make the same mistake of paying for expensive classes and coaches granted i didn't finish paying 90% of the back because it felt like a scam to me.

Some of those "gurus" are scam artists, and many of them charge enough money for their "lessons" that you could just as well put that money into an investment.There are even BP subscribers who will tell you it's possible to invest with No Money, and they'll have tales to tell.

Scams of all shapes and sizes have increased within real estate lately. 

They also scammed my tenants who rented it sight unseen  - handing over the keys and running off without even a walk through.

So do a rent survey using the usual sites as the source (Craiglists, Zillow, Hot Pads, FB marketplace, etc.) paying particular attention to the cheapest units on any of those sites (realize outlier cheap units may be a scam and not really exist).
