Selling to a buyer
I understand you will help facilitate the transaction since I am a private party?
My buyer is ready to buy the car...but has to sell his first and has a buyer
ready. He wants me to take mine off the market but we need to make a
contract of sorts that gives me a deposit and my promise that I won't keep
the car up for sale. Can that be done through you or do you have any ideas?
I agree. Nobody here can answer that question.. But as for suggestions, tell your buyer the car goes to the first person who comes bearing cash. If you go the deposit route make sure there is a deadline on when full payment is due and that the deposit is not refundable if he changes his mind or can’t come up with the rest of the money.
I would tell him first come, first serve. He may end up wasting a month or more of your time when you end up finding out he can't get the money for your car.
You could tell him to give you a non refundable deposit to hold the car for a week or other time period. Your time is worth something and if he wastes it he needs to give up his deposit. The whole thing sounds FLAKY.
