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." 

People will be happy to be fit with little to no effort and will live forever in simulation servers and whatever becomes of quantum computing will help organize the undeniable concern of over population.

(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.

ADT security signs, simulated TV, put a couple lamps on timers, etc. 

@Steve Wilcox I ran a simulated 5 year adjustment to 7% on my current properties, given the reduction in principle and an increased interest rate my payments would jump about $70 per unit for the mtg.
