But if you are buying off market, using BRRRR, neeing to refinance out in under 6 months, etc. then that will narrow the bandwidth quite a bit. 

Well we made it through closing (the quickest I've ever been through in under 10 minutes!)

We are on our 49th flip in under 2.5 years.

Unfortunately, when underwriters get inundated with deal-flow, things tend to move a lot more slowly.Poor communication.

Do you recommend I put the property I am interested in under before I ask the contractor to walk through the property?

Most properties that are appropriatly priced fet 5+ offers in under a week.

The way i understand it is, I find a property and get in under contract then sell the contract to a buyer and make a profit.

The better question is can you find a deal so good that would even allow you to have 25-30% equity in under six months? 

TLDR: Call around to lenders and see if you can find one that will help you aquire a property without a down payment if your numbers come in under 75% of ARV.I am just getting into the game myself and I lucked into a lender that is allowing me to work deals in the following way:When I find a property at under 75% of ARV including aquisition / holding / rehab costs then they will fund the whole thing without any cash outlay from me.What they do however is have their own appraiser give them valuation for the property as is and the anticipated ARV given the rehab that I will complete (they require details on exactly what I will do to rehab the property) as well as my costs for the rehab.

If you want to go join a forum inundated with contractors you'll see a great deal more trolling, pissing matches over meaningless code interpretations, and poor interpersonal communication skills, which not to broad brush, is much more of the norm statistically speaking in the 'contractor' world.Regarding contractors using stolen materials, or stuff they have in inventory - I've seen it, now at least 5 times.
