Deal with no heirs. How to move forward?

[Jeremy Aldridge]

Hey BP community! I have been working with a wholesaler on this property for about a month. We have been searching for heirs as the property owners have passed. Just when we think we have what we need the closing attorney shuts us down. My wholesaler is giving up on the property labeling it a "cold case". I refuse to believe there isn't something more we can do. The house sets a block off Main st in a vibrant downtown. Has anyone had a situation like this? How do I move forward? Thanks in advance for your responses.
