MLS protocol, my Agent is refusing showings proper to closing

[Brian Shablow]

I have a MLS property under contract and want to use a double closing with a Buyer. I am told it is my Agents FIDUCIARY responsibility to not allow potential buyers to enter the house I fear of losing his License. Is this correct and now I will have to find hard money in lieu of transactional until can close with Buyer. This was crafted only after like a snake in the grass he found out I wanted a double closing in lieu of having contractors giving quotes to renovate.
