Fix and Flip Analyzing Tool

[Sean Grady]

I'm considering doing a couple flips this year but I'm concerned about the data in the BP Fix and Flip tool.  It doesn't appear to calculate or take into consideration the "down payment" for the acquisition!  This seems like a huge part of acquiring the property.  Should I add in the amount of the down payment in the closing cost section?  The tool doesn't say anything about the down payment.  

Am I missing something?  Is there a strategy I'm not aware of that doesn't require a down payment?
