When I bought the building and I started checking him out, I saw that he had falsified the spelling of his last name in order to hide three recent evictions on his record (the previous landlord was too stupid to check his ID).

The double close is to hide the end buyer from the seller, right?

It sounds like they're trying to hide something or stop you from digging deep into the condition of the home.

Hide behind a employee title.

The numbers can be overwhelming for this market, but often times there's value hiding in plain sight! 

This is a financial transaction, there are a lot of financial transactions that require an SSN, loans etc. my question would be what is he trying to hide? 

These folks are hiding, and they are in a very bad place. 

Don't hide.

You could get clever and hide them in strategic locations, but the truly determined will ultimately find them anyway.
