Wholesaling a property that closes in less than a week

[Thomas Valdez]

I just now found a property that is scheduled for foreclosure on oct 1st which is next Thursday.. comps tell me ARV is 280k-306k she is behind on her mortgage a total of 71k meaning she has 215k-235k in equity, I'm not sure how to calculate my start offering price and my max offering price to the seller.. i want to make a solid 20k on my end and I'm assuming without seeing the property yet its going to need 20-25k in repairs.. if anyone could assist me in going about this i would really appreciate it!
