Buy low and sell high is not a real strategy much more complex than that, any real trader knows that. lol Stocks do have their advantages in the liquidity department. 

While many middle-men were vaporized by that internet phenomenon; travel brokers, traders, insurance, etc., Realtors® and mortgage brokers have gone unscathed thus far.

I haven't earned the right to give you any pointers on how to manage that, but just be careful.Equity traders like to teach/preach the use of strict self-imposed trading rules as a risk management technique.  

For ex. if the assessed value is 200k and the mileage rate is 1 it means you going to pay 2000 in taxes. 

I've worked for forex broker for couple of years as head of key account management which helped me to build my network and expertise in regulated business.

I've never seen a Tesla in Auto Trader, but then I rarely look at it anyway. :)

I guess it's quite obvious that otherwise it would be like playing with FOREX.

I know that major chains invest in areas where they can make money, so a Costco, Whole Foods, or Trader Joes signifies a neighborhood getting better while a McDonalds, dollar store or oil change place does not. 

Some recommend you start a C or S Corp to avoid dealer/trader status with the IRS, especially if you plan on wholesaling some of your properties you get that you do not plan on flipping.

I would love to trade real estate secrets for some insurance market advice.
