The seller's attorney changes the dynamic more than the price does.
At the standard level, you can sometimes recover by explaining the process plainly and showing the seller that your assignment fee comes from the buyer's side of the spread, not from the seller's proceeds. She gets the price she agreed to either way. A lot of distress cases get over that hurdle once you separate those two things clearly.
At $1.4M with an attorney in the room, the attorney's job is to protect the seller, and they read assignability clauses for a living. So the conversation does not really get easier, but it shifts onto different ground. A few things that experienced luxury wholesalers report doing:
One is being upfront before the contract is signed. Some operators in the luxury tier disclose their role as a wholesaler at the start of the relationship, framing it as a service that finds the right buyer for a property the seller needs to exit. The seller's attorney can review the contract with no surprises. You lose the element of shock, but you also do not lose deals at the finish line.
The other is the double close, where you buy the property and then resell it. The seller never sees an assignment at all. A title company handles two back-to-back transactions. You still need the capital or a transactional lender to fund the first close, and that is worth understanding before you need it.
I want to note that contract structure and disclosure requirements vary by state, so before you run this in the luxury tier, a real estate attorney should review your approach. That is a one-sentence caveat that matters a lot at that price point.
What state are you working in? Some have specific wholesaling disclosure rules that change which of these approaches is cleanest.
