For most people a house hack is a great start. 

I think people can definitely get rich quick.

One of the things I love most about this community is that people are not afraid to challenge the status quo (ie. the smart thing to do is contribute to your 401k).

At the end of the day we can screen our tenants all we want, but cannot control what people do.  

The challenge with unsafe areas is (1) potentially higher cost of maintenance such as broken windows, etc. and (2) this is by no means meant to be discriminatory but anecdotally from people I've spoken to the challenging tenants tend to be at the lower price points.

Typically people only get insurance on things that they own, or liability insurance for their own protection. 

People are very willing to suggest all sorts of contractors that they have personally uses. 

I know it may sound common sense, but people do struggle with understanding that water follows gravity.

The biggest mistake people make is not having enough reserves before going into real estate investments.

I haven't heard of any, but met with a few people in the twin cities last year.
