I buy materials from specific distributors, good product, warranty, net billing etc.I think using a reputable general contractor is best for most people, volume of flips is generally the focus (plus margins) Christian's comment said it best.

Especially in a situation where one tenant is a distributor and the other tenant is a service provider for a major cable company with several work trucks.  3) Establishing a cadence of communication with each tenant.  

MLM based presentations  lead with why they are doing this all for the family big picks of family etc.. those are red flags..

I buy my cabinets (all wood boxes w/ dovetail drawers) from Next Day Cabinets although I have used Wolf cabinets previously via a GC who is a distributor for that line. 

I went to a plastic distributor and fabricator and got a TON of the pieces of plastic cut down to a standard size 18x24 and they carried the H-frames on the cheap.

Or stick with locals you meet at the REIA or BP meetups... paid training can be good but you need to be realistic about it... most of these types of deals are like MLM amway things only the few at the top make big dollars while you feed in your membership dues  LOL.hope this helps. 

Yes, the recruiting and mlm side is a big turnoff.

So after reading Rich Dad and partaking in a MLM for a short period, which I am no longer a part of, I decided I wanted to do something more active with greater upside.

I used all of the systems offered in the M5 while doing MLM.

Like windows for example, I am a distributor, so I purchase directly from the factory, that is a significant saving.
