Question

I wanted to see if this is possible or if anyone has done this. I am looking at wanting to rehab some properties (possibly) with some partners of mine. I am looking for vacant or run down homes only (for these types of transactions) 1. Is it possible to try to get a 45 - 60 Day close get into the property and then either do a lease w/ option or do a double close and sell the deal for retail? 2. Or should I get someone to lend me money for 45 - 60 days do the work, and than sell it? I am trying to do some brainstorming, if anyone has other thoughts I would greatly appreicate it.
