I've seen managers give presentations to DIY landlords, teaching them how to better manage their rentals, and they hire the property manager once they realize their mistakes have been costing them money or time.

They also present a more palatable house hack then having roommates  Note as a teaching experience, the negative initial cash flow is more palatable.  

Market is priced based on auction style, so a lousy house can be sold higher than a good home sometimes depending on seasonality and availability of buyers.

I'm not concerned about teaching them a lesson.   

This will teach you the business in a hands-on way that no coaching program will do.

A good program will teach you how to do this. $20k will get you nothing to own on your own and you'll be untrained doing it.

It could also teach your kids about having a good work ethic and setting an example for them by seeing the rewards of investing time (and money) and effort into something.

Hey Amir, You are right, there isn't many resources out there that teach you how to do ground up development in Houston.
