Seller won't let me in a home I just purchased

[Ian Whiteman]

This is a new one for me. I closed on a home today, about 3:30 on a Friday. At closing, there were no keys. When I reached out to the seller to collect the keys he tells me he will not turn them over or let me on the property until his wire transfer clears on Monday. Apparently, he has not received his transfer since the closing was so late on a Friday. He is not renting the property back. I don't see how this is my problem in any way. I have contractors scheduled to go there tomorrow and he is saying he won't allow it. I thought I legally own the property now. Am I mistaken or does he have a leg to stand on?
