How do you handle an agent who has their own closing company?

[Larry Hill]

Hi; been working on a deal, with sellers real estate agent commercial property. Seller and agent, already have a closing company. I have one also, agent wants to submit a letter of intent, with the sellers agent closing company, with my offer to the seller. I'am not sure if the closing company is investor friendly. Should I call the closing company, before I sign and see if they are investor friendly? If so how would I ask the closing company if they are investor friendly? Example: do they do double closing, flash funding, transactional funding? Not sure how to ask the question without raising suspicion! It seems like it could be a good deal. And if the closing company is not investor friendly how do I proceed from there to get then to use my investor friendly closing company? Thank you, so much for your response in advance.
