I would not be doing it to make extra money, I would do it to avoid constant phone calls about unclogging a toilet, changing batteries in smoke detectors, changing lightbulbs, small things like that.I have seen this suggestion in other posts on BP.

You will have to take a 100 question quiz at the end of each module to show you've done the studying/course work.

@Omar Alvayero - Check out module 6 and there are videos explaining both of themhttps://www.biggerpockets.com/courses/a-beginners-...

With regards to real estate investing, TESLA is building a very large (second largest building by square feet in the world) to build the car batteries for mass production.

You hate to send someone to fix the heat to find out the tenant doesn't know how to change the battery on the thermostat.... but that is the risk you take. 

It's been taking me a while (the reading is great for falling asleep), but I recently switched tactics and am now completing about 2 sub-modules a day.  

When we were developing commercial business parks back in the late 90's we not only hired management companies, but hired a battery of consultants, a very expensive proposition, to provide us guidance on various best in practice options for HOA's to operate. 

We were just contacted by the wife that due to domestic battery against her, the husband is in jail.  

Personally I think educational degrees are the same, you only use 15-20% of what you learn, it would cover all aspects of dev but nothing specific or not only what you need, I'm actually looking for a good program like that, but I would like to only enroll in modules or so.

Seems to work well, they can use the area for decoration; battery operated candles and such if the cover is unscrewed but otherwise it's made to look clean, fresh and nice but not to be used.
