He is still scheduled on the calendar to arrive this Friday. 

As a layman, I just see so much alledged co-mingling and alter-ego use...Without disagreeing with your analysis (no question there is a cost to forming and properly maintaining an LLC), I still arrive at a different conclusion.  

If I arrive on March 1st and find the property vacated (cars gone and it's clear the inside was cleared) am I permitted to change the locks and take possession?

This is the ultimate reason why the bottom will come and go without most capitalizing on its arrival.

A lot of bookings were last minute (several same-day arrival).

But multiple credit cars, car payment, rent is a no go.I've had a few tenants that went thru foreclosure when the market crashed, and want to rebuild.

Fly to the US, and sign it in person with a mobile notary (wet signature)Going to the embassy is not an option since getting an appointment over there can take months...I had a thought which I spoke with fellow investors, to sign the documents with an Israeli notary and then get an Apostille stamp. once I have it all with a wet signature I'll mail the documents with DHL/UPS and it will arrive by the lender/title company in 10 days.As far as I know, a notary signature with an apostille stamp is valid for every legal document almost all over the world...What do you think? 

Only received about 5 applicants so we brought it down to $1800 + $150 utilities The tenant will arrive in January!

If you ask nicely MAYBE you can ask the Sellers if furniture can arrive and be put into the garage.

Many wholesalers crash and burn because they miss this point, focusing too hard on sealing the deal instead of really listening to the people they're supposed to help.
