Cash reserves + flipping?

[Account Closed]

I understand that having some of your own saved up money($3000 - $5000 worth) is useful in case something bad happens.  I can definitely see this been used for rentals, but what about flips?  

If I was raising capital for a deal, could I add an extra $5000 to the equation to act as cash reserves?  Would I need to use any of my own money as a result?  Or is there something I'm missing?

Thanks in advance!
