Maybe I'm wrong, but you're holding them to unreasonable standards.In Orange County, 12% of starter homes sales fell through in 2016 - Source - Why should it be expected for wholesalers to operate at a margin of success we don't see with standard real estate purchases?

You'll almost always make more money with appreciation than with cash flow, but if appreciation is your sole play, if your margins are so thin, or non-existent, you're on shaky ground.

If something with good margins gets sent out it's usually under contract in no time. 

But most properties under the $2.5m pricepoint (which is considered a "starter home") are still quite competitive - particularly single-family homes versus condos (which are marginally more plentiful). 

Hopefully you are having some success with good profit margins on your investments.

Doesn't sound like there are high enough margins in the first place.

I feel like if my buyers know my margins it’ll make them want to do further business to find these deals.

Yes, the margins are a little less than being very hands on with an Airbnb, but they handle thousands of properties probably just like the one you are looking for. 

This one looks marginal at best

I consider myself marginally successful and I wish I had a mentor 25 years ago.
