If you're willing to invest a few $ there are companies that can simulate what the end product will look like; virtually stage it. 

I'll call it a simul/double closing which is common verbage in the industry.So what is it, or how is it different?

Definitely use a score simulator.

Most of the good ones have certain features like simulated exams, pre-assessments, flash cards, etc.If you need a recommendation, CompuCram is a really good program.

He has wanted to be a pilot since the age of 5 or 6 and flies this plane on his computer simulator.  

@Jackie Lange Thank you so much for the rundown on the foundation issue and to @Joseph Weisenbloom for the reality check.I didn't do a good job of communicating that as I'm abroad for the time being, I'm just using the data at my finger tips to do simulations and practice the math.

If you plan on expanding on this particular model and adding things like sensitivity analysis or any type of simulation then I'd back track a bit and create separate input screens that then feeds your actual model.

Yes I've been thinking this for years, I do run a lot of complex economic simulations, DST is not interested in the QE environment but DST becoming sexy in QT environment. 

Not the indoor simulators but the full blown driving range. 

The lender could try running a what if simulator.
