(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. 

The green areas are actually Crystal Ball inputs that I use to run Monte Carlo simulations.  

You are now saving and simulating your future expenses (ignoring rental cash flow to be conservative). 3)Take out a heloc on your home, but don't take any money out yet.4)Look for a fantastic deal in your local market.

The time simulation of growing development makes it look like land in very limited supply.Terry

Thanks @Sean MyersUnderwriting that Sacramento deal simulating a cap rate increase to 6.5% brings me to an IRR barely above 0%, so I guess it's good that I don't go underwater :-)Of course, that is true until it's just the cap rate to suffer and not the actual rents with vacancy and discounts, otherwise the debt service might become hard to cover...Thanks for sharing your wisdom!
