Lease option, sandwich lease - assignment at closing, to overcome seasoning issues?

I'm wondering if it's possible to do an assignment fee at closing for a sandwhich lease option.

Scenario:

I get house under lease option for 125k option price

I find a buyer who rents to me for 1 year and does a option with me to purchase house for 150k.

Because of seasoning requirements, isn't it you have to own the property for 90 days, the buyer would have an issue if i did a simultaneous closing. That said could I assign the contract to the buyer for 50k and that show up on the closing HUD1?

To me that would be the easiest way.
