If I double close do I need the money to give the seller at closing ?, I’m not using my money but the investors for the property they will buy from me at a higher price. I don’t want to double close with the seller and the investor at the same close time. Can I arrange different closing times without having any money come directly from me. The investor is a cash buyer, I wounder how double closing works in this situation.

The idea of a double close is that the money from the buyer (investor in your case) passes to the seller and your cut is taken out in the process. So the answer to your question. No, you do not need to have the money to pay the seller if the double close is done correctly.
