The seller was foreign, and had picked and escrow company that hadn't been in business for long. I was originally worried it was a scam and someone was trying to run off with my money, but that wasn't the gig.
The two owners of the escrow company had owned multiple other escrow companies that were shut down. No complaints against them, so it's not like they were taking people's money and running.
The escrow 'company' didn't have any sort of need for a paper trail of where money came from when buying my house. I imagine if I had shown up with a suitcase full of cash speckled with blood and coke they wouldn't have cared.
There's likely no record of where all the money came from for me, (tech money) nor any of the other foreign buyers they regularly service. They're likely shut down again and opened with a new name.
