. - First window order arrived damaged and incorrect specs.

They pay the full amount when they arrive.

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).

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.
