Here are additional details:

1) transaction did not close as a result of the wire fraud

2) this would have been their 2nd vacation rental

3) they are filing a lawsuit against the law practice that handled the deal - 50/50 chance of recovering from the lawsuit; law practice had NO insurance coverage in place for this type of loss 

4) $450k total funds involved, $300k recovered, $150k not recovered

5) FBI is involved in trying to recover the additional $150k as well

Thank you both!
