I have advertised through Hemlane, ZIllow and also MLS. 

So the major issues in a house are a foundation issue or a structural issue, the next tier down would be a mechanical issue like Electrical, Plumbing, HVAC, then roof - which isn;t an issue a new roof is very common in a fix n flip, and then the outside facade: Brick repair, driveway repair, brick pointing. 

Most of the methods are for advanced investors and not nearly as common or easy as portrayed by YouTube gurus selling courses for a living.

@Craig Oram this is a common issue.

I recommend being anonymous.In some cases if you have a PM, let them advertise it as their own.If you have an llc then the lease and payments go to that.While I do introduce myself to tenants, I don't advertise I'm the owner publicly.

And while that number varies somewhat, the most common number of different issues that minimizes risk is 21.  

I recommend you include some of your key qualification criteria in the advertisement.

I will often go against the common investor thought and defend my position based on my experiences.

what are the laws in CO regarding unlicensed wholesalers tying up property advertising it and collecting a fee at closing is that even legal in that state. ???

It's super frustrating when you work with investors every day, and the common refrain is I want to buy a passive turnkey property, but it must cash flow.
