@Christopher Phillips correct, margins are slim.

In terms of wholesaling you need to be close on your rehab estimate but you do not need to be exact, I'd say its more important to be positive you have a deal and more about presenting a range of repair value to a buyer that is not made up or intentionally low to help drive your margin. 

With that said, the margins are quite small, however, I'm sure there is room for improvement and appreciation.If you could, please, I'm not quite understanding the Management fee (I understand the 6% being on an annual basis of the $18.6k) - but then there's the $750 placement fee and 50% of the rent?

I would hope the extra two weeks of holding costs wouldn’t kill your margins.

I have 40 grand in a margin account.  200 grand from selling my house and another 98 from flushing an IRA.   

I need to determine how much someone else purchased a note for and what kind of margin they are looking for to flip it.There's a property I'm pursuing that is a little out of the ordinary - so I can't quite wrap my head around a few things.

Welcome, @Alexander Jones.Yes, SoCal can be a tough nut to crack for newbies.A couple years ago I mailed out lots of letters to homeowners in LA County with no luck.Then I tried rural Kern County and got a deal from a distressed homeowner in California City.The margins were not as large as they would've been in LA or OC, but I was able to rent it out for 2 years before fixing it up and selling it for a decent gain.Also, have you considered an owner-occupied small multifamily for your first deal?

Margins are tiny and the big companies that buy your chickens (and sell you the feed) are just evil as hell.

The Buy and Holds in that area have pretty good margins right now even in the inflated market.
