Yes, the Monti Carlo simulations can be used for many situations -- the statistical math model is pretty sound. 

I understand I can "simulate" all-cash offers with private money and/or hard money loans.

I have run this simulation for the same market… “which is better to buy… 3 houses at 1/3 the high priced house, or just the high priced house?”  

Just run a simulated income statement on each unit and if the numbers work and you are satisfied with the potential return, pull the trigger.

Awesome fridge.etc. etc.Analyze your numbers, run simulations, run scenarios and then come up with your systems you will make far more money!

I grew up playing video games like Sims, tycoons, and investing simulators.

Simulate that, do that yourself, and see if a bunch of good reviews will pop up, or poor reviews, etc.

I'll use our FICO simulator to figure out what you need to do in order to be out of that range so that we're in the clear in the future, but it's on you if you actually do those things or not.

All growth simulated by investors...Home ownership rate is all time low in 50 yearsMortgage application lower (Cash purchase)International investment all time high...Similar scenario happen in US in past..?

Seriously, though, I like to keep it simple (market is high, about right, or low), position myself accordingly and while still covering myself for all reasonable outcomes ... beyond that, I think we can quickly pass the point of diminishing marginal returns on our analysis and into the realm of false precision.When I wore a younger man's clothes I used to do something similar, except back then I was working at JPL and running monte carlo analysis and every possible worse case I could throw at the spacecraft simulator.
