I am looking to writing an aspiring story about my success in real estate and to multiply with great partners! 

What you go on to describe here is the money-multiplier effect, or "monetary velocity". 

Lets say the Gross Multiplier is 13 and you raise the rent only $25.

If you want your own office you can do so too, and build your team and make money with your team and empower your team to build their own team so that you multiply your efforts on training your team and sells.

Multiply that by the national average commission and you will have average GCI per agent.

Once you have your list rank ordered take the subject property and multiply its square footage by the average of the middle 80% of the price / ft entries.  

@Dan Zaccardi Take the population of a town, multiply that number by itself, then add to the result the population of the town and then divide the result by the population.

However you should work towards an 8-12 time multiplier.

For this purpose, the fair market value of an undivided interest in the Property is equal to the Co-owner’s percentage interest in the Property multiplied by the fair market value of the property as a whole.11.
