There are all types of people in this world, many people have different stories.

The marketer (guru) severely understates the amount of capital, time, and knowledge needed to produce successful results.And the above mentioned are the BEST case; not even mentioning the guru strategies that are fraudulent, illegal, unethical, and plain not realistically achievable.  

thats horrible, hopefully you can get some of the cash back. there are just horrible people in this world.

It is sad that no enforcement can even go after their fraudulent business practices. 

And people cheered it, until.....

The other day I started the thread Why do people Buy Property in California? 

North side Chicago I have never even had to give a tenant a late fee and none of the tenants I have placed for clients have ever given them issues either, properly picked people pay like clockwork on autopay.

no reports of incidents with our residents but there were some people injured and some homes damaged. 

Maybe, but so far the reports are about neighborhoods where people have real money.

I know BiggerPockets already has a number of great calculators, but is there anything niche that people are interested in?
