@Wendy Owens I have an opinion on a few things. 1) It's not so much the cash you need as the cash flow, so you can reverse engineer $10/month and figure out the best way to do that. 2) Dont forget about taxes on flips, you're probably going to pay nearly 50% in taxes. 3) Any way to trim down your living expense?
