In economics 101, the more you produce of an item, the average cost goes down.

We then refinanced the property and it has given us $140k in cash back and continually produces $1,800/month in cash flow.

Keep in mind that in addition to not producing any notable revenue for the company, you come with a certain amount of risk or liability that they assume responsibility for.

The low initial investment, quick cash, and eye opening profit margins allowed me to invest in, and now own, a nice portfolio of income producing real estate.

However if you look at the loss expense together with the cost of producing the product and marketing expense I think you'll find the profit margin in line with other insurance companies.

I am not a big fan of having 20 properties that only cash flow 200 per door versus having 5 that produce better numbers.

I now own a nice portfolio of income producing real estate – virtually all of it purchased with cash by flipping mobile homes in mobile home parks.

This can be tedious, but will on occasion produce a path to acquisition that is unavailable to remote buyers, and too much work for local ones. 

The adjusted taxable income is then used to calculate the tax you owe the IRS, producing the value for line 16 in the 1040.

Similar to what others have stated, if I were you, I would: 1) become a top-producing agent 2) start building out your team internally within the broker you're working at 3) once you're client base is large enough, starting your real estate brokerage can be beneficial.
