Obviously this will take time to grow but in time, more and more deeds will be publicly auditable and immutable databases.

You can use the same ratio, if you believe that is wrong you can allocate price but have to defend if audited.

Start analyzing deals and ask her to show you some properties on your free time.Tax season/Year end Audits should have passed so hopefully you now have some free time!

Asking to show the Bank Account may cause him to think twice in consideration that it was explained to me that if an Attorney in NY is undergoing an Audit towards his Escrow Account, he cannot practice until the Audit is over.

If you haven't been receiving audited financial statements every year that's troubling.

What's even worse is I'm told that I'm likely to get audited by the Japan tax authorities because I've listed a previously cash producing asset as suddenly having a gross income of $0 for the entirety of 2017, which is seen as a major red flag.Does anyone have any recommendations for what actions I can and should take given my situation?
