So everyone can look out their windows and see "Golden Girls" and "60 Minutes" 100 foot high.Does it exist somewhere, or is it just a concept?

As @Frank Chin mentioned ‘no doc’ loans were a Wild West approach years ago but the concept has matured in today’s market.

You can get into a world of hurt if you are not up on basic concepts like those being discussed here. 

Honestly, the thing I wish I knew before buying my first house was the concept of househacking at all!

The concept of advertising comes in to play when you are first rehabbing  a property.

PM me if you're interested in getting the numbers I find.Best,JonHi Jon,I said "average drop of -35%" as that would be a ballpark figure for the overall LA market, according to your data, but risk could be different taking into account the particular features of a property, its specific location etcMany concepts from the stock market can be applied to real estate investing, like volatility, maximum drawdown, etc.. it is possible to get an idea of what those figures may be for a particular market observing historical data. 

Which "concept" you go with, or combination of them (Lay out your plan with numbers) as you go through your plan, is going to be dictated by the numbers$ needed throughout your plan.

Any thoughts on the simple concepts I have mentioned?

Do you go all Sheldon (Big Bang reference) or something simpler? 

@Solomon Morris Thats a very good point, and a very difficult concept to force into my stubborn mind haha.
