Holding and Financing Costs? Calculating and difference??

[LeAnna Davis]

I am a brand new investor and have a couple questions.  Ok so I have a property that I am looking at that has a potential to be a good flip.  Profit is $20,000 BUT I have not calculated the Holding costs or Financing costs yet.  For safety's sake say it took 5 months to fix this house up.  Then what?  The monthly insurance is roughly $40 rounding up.  And monthly property tax is about $130 rounding up.  Any help?  Google has not helped much these past two hrs.  What else do I need?
