Infiniti Turn-in to receipt of title or equity check?

In Houston…My lease expires 1-21-22,
If I turn in 1-21-22, how long till I receive a. payoff equity check from Infiniti Financial?
If I buy at my lease payoff of $28K and wish to resell it to CarMax for their $39K offer, how long to receive the title from Infiniti Financial?
WHY is buying/leasing a car so bloody difficult?
Thanks to all in advance.
