I'm not a lawyer nor an accountant: However, I'm to understand that if the lender requires you to PG the loan, then your personal income/assets could be on the line in the event of default.

I plan on working out of PG County, Frederick County and Baltimore once I get started, there's barely anything in Bethesda or DC that will make any kind of money.

I don't have to wait on any contractor and/or locksmith to rekey it.Just make sure you have a copy of the current key and then you can rekey it to another key yourself.Put in the old key, turn it a quarter turn, then put in the rekey tool into the separate little pin slot until it clicks the lever in there.

Slot machines get some extra income lol

If the project fails for example the bank has a strong backer on the loan to be made whole with the PG.   

Tonight at 9pm, I received an email from Diane (one of the VAs) to inform me that I now have two showings scheduled for the first time slot and one for the second time slot.  

They could have put that into a breakout session and dedicated the main floor presentation for that time slot on more relevant items like bankruptcy/foreclosure or RESPA/compliance items.

The labor is lower, but that may also make it harder to treat your container as a "normal" shipping container on a boat - the window frames, door knobs, etc may stick out further than the regular wall of the container, which means they'd have to leave an empty slot on at least one side of your container. 

Granted, no risk no reward but this isn't a quarter slot machine in Tahoe.

The solo 401K owner wouldn't be required to sign PG because they are less than 20% owner.
