I've been trying to simulate the calculations on different listings around here just to practice the process and I kept seeing negative cash flow so thought maybe I was doing the math wrong/not enough units/just a poor investing area, but I think having the attitude that someone is paying for much of your mortgage and one day you can capitalize and be positive is probably the right strategy to have around here.

Even though I knew I wasn't going to bid anything I wanted to simulate that I was.

Here is a simulation using a $150K Purchase Price with 25% Down.

The stipulation was: "This simulates a person depositing their Monthly Income into the line of credit at the beginning of the month, paying Monthly Non-PI Expenses via a credit card, then using the line of credit to pay off the credit card AND the Monthly Loan Payment at the end of the month." 

(I ran a mortgage amortization simulation, if vendor is not looking for a lump sum, they can still get a nice monthly profit).  

@Nicholas Spinazze Yes, it spreads it out and runs a large number of simulations. 

Now Im hearing about a trust that simulates a series LLC... ?? 

That's the only way to spot an issue/clarify an assumption ahead of time.We use spreadsheets, of course, but the final summary fits on 1 legal sheet.I do recommend you play with some Monte Carlo simulations on your total cost before you get to far.

MySCOREiq or identityIQ [same parent companies] - my personal favorite, and also offers a "what-if" simulator to see how certain 'moves' will affect your scores >> mySCOREiq I Credit Report   2. myFICO - very similar   3.

I just made a first order simulation there.
