The end buyer is cash and we can simul close on that in the afternoon.

We get the offer AFTER approval and still do a simul close.

Some of us can run a simulation to see if there are any opportunities for quick improvements. 

However, you can simulate an interest only loan by putting a sufficiently large number in your n (or years) field.  

So, when you go to teach it to someone else, you find that you must rediscover your own learning process, remember the lessons of your past experiences and actually digress into conscious competence and then even into simulated conscious incompetence: "how do(did) I learn this?"

Here is a simulation of what it would look like:Obviously, there are many factors affecting cash flow (location and condition being two major ones).1.

I took a prep course through NYREI, they have a "final exam" that simulates the real thing, found it immensely helpful as well.  

Try woking out a simulation where you pay each one off before buying the next.

If that's the case, you really only need a dedicated account (or bookkeeping to simulate this) in which disbursements and certain expenses (like taxes, insurance, and capex) are recorded.If you are asking whether the property management's bookkeeping is standard, this is a much bigger question.I can't imagine that a legitimate PM would have an individual trust account for each owner.  

You can even simulate your actual credit score.
