How do you calculate profit??

[Komal Patel]

Hi BPs Need your help urgently. I am working on my first deal. Actually ARV of house in realist report is $418k and bank accepted my offer of $330k.. (315k was offer amount plus 5%auction charges-17k ) Which was pre auction offer. Rehab estimation will be around 40k .. Plus I have to count on closing cost and holding cost too. So when I run numbers it comes around ARV value. So how do I decide my selling price ?? How much average profit i can calculate?? Do I count on ARV value for the profit?? Should I go for this deal ? Does the deal make sense?? Or I still need to negotiate with bank?? In other words how does it work if I can negotiate with bank?? Bcs it was online offer & they sent me contract which I have to sign today. (Valid for 24hours) I am really confuse. Property is really good, water front with pool family home in safe neighborhood. Pls reply asap..thanks in advance Komal
