lender problems w/ options

If you get an option to purchase from the seller and find a buyer who buys for more is there ever a problem w/ seasoning if you do a double closing? I would rather not have to assign my contract and have my buyer know how much I made off the deal.

Sure, there can be a problem with seasoning in the scenario you describe. But there are also ways around it. For starters, a different lender can be used.
And, by the way, don’t give too much thought to what your buyer thinks about your profit margin. If the deal was good enough for him when he signed off on it, it should be good enough now. Is he under the impression you are a nonprofit organization?

good point. I’m not talking about any situation specifically though. I’m looking for that first one.
