If they give a buy rate at 1.27 and I upsell it at a 1.37 for 10 points. All they gotta do is back door and pay someone 2 points and sell it at a 1.29. And the merchant will def. take it. And that's what happened

Or, you are selling the deal at 1.37...and broker X down the block, who submitted the same deal and got the same offer, sold it at 1.30

first one back with contracts means you no longer have the luxury of upselling the deal all you want. Someone else will come in with the same offer and same fund...and sell the deal for three points less.
