For me it's been as simple as simulating a correction and removing, for instance, flip income, as well as reducing gross rents. 

That's the same simulation that posits if an axe-murder asks you if your family is home because he wants to kill them, you must answer honestly because lying would be immoral. 

I had a degree in finance and economics from a Big 12 school, owned several single families and a multi family property, and yet every time I played that game I learned something through the simulation that helped me invest and run a better business.

It's very easy to simulate this condition with excel.

I always assumed they have different title insurance companies that they write through.Even if you have trouble finding a title company to allow the simul close, you can just use transactional funding and make your closing on the A to B go through with a wire from your one day loan.

Robert - I know of someone who built an investing simulator that is really good . . . we lost touch for some reason, but I'll see if I can find him.

We're about 75% of the way there, with $1M already working for us.But even though the math all works out and all of the simulations I run seem solidly in my favor, I'm still very concerned about having all of my money in a single basket. 

For Business (in addition to simulations):A semester long project called "Find My Next Investment Property" - which is exactly what it sounds like.

look at City Zenith software to create a digital twin it allows for 1 standard design to rapidly be applied for all site variations and saved for submission to a modern Planning commission to run simulations for all utilities and impact on the surrounding area.

Young James Kirk defeated the "Kobiashi Maru" simulation by altering the software program.
