You can even simulate your actual credit score.  

@Ryan Blake - I was simulating some of the protocols we have in my full time job - our office implements daily enhanced cleaning for the limited number of employees that are allowed on ground.

The award was called “The Warren Buffet Investment Award” which I won for beating over 1,000 students plus teachers in a 10-week stock market simulation game (I turned $10,000 into just over $21,000 in 10 weeks).

CreditKarma.com has free reports and a credit score simulator.

What I'd like to do is use it to run Monte Carlo simulations on capital mixes and see where my optimal profit will occur.

I did my analyses at list prices and deep discount rates to simulate off-market deals.

Most lenders like we do can run a What If Simulation Report for you, but to do that they will need your permission to look at your credit profile.

Let's try a mathematical simulation to see if @Scott Trench is wrong.Lets say you have $20,000 and buy a $100,000 rental property using banks money.

I won't be investing in the stock market yet because I don't know enough about it yet, but I am doing some simulations to practice, and I'm not going to do forex because it's too risky.
