I have been plugging in hypothetical numbers in and having trouble figuring all the numbers out. Anyone able to help?

My question is: Total cash invested says $7749 after refinancing; however, the holding cost during a 3 month rehab is (interest payment on hard money loan x3, home insurance x3, and property tax x3) $6335.50. The hard money loan is for 6 months though so the interest payments for the next 3 months is total $5685. Does this mean that for the entire deal from purchase to refinancing, I put in 7749 + 6335.50 + 5685?! Thank you so much in advance!
