You can always put it into a trust then make the trust beneficiary an LLC at a later date.3.

So my assumption is that 01/16/2018 is the date it was recorded. 

You can always find something to deny on or go with a different availabilty date/better qualified applicant.

Man, these dates are killing me.

Here's a suggested system:123 Sample Street     - Property          - Receipts          - Invoices          - Photos and Video          - Other documents     - Tenants          - 2015-01-15 Move in - John and Jane Smith          - 2016-01-15 Move out - John and Jane Smith          - 2016-02-01 Move in - Jack Squat     Every file should be named with "DATE - PURPOSE - LOCATION - NAME" which will enable you to find things using the search feature.

I would make the payments directly to the mortgage company and would either have the statements mailed to me or see what I would need to do to get online access to review the account.In looking online, I see a few other strategies such as deeding the property to a land trust where the buyer would be the beneficiary and some people discussing the transaction with the bank and being open about it. 

after effective date, 60 days for financing contingency after effective date, and another 15 days after loan approval for closing? 

They show checkout dates in different ways. we had a problem with our cleaners when the platforms changed the way it viewed.

Should I take the security deposit from them or closer to the moving date?

Should I just hope closing goes ok and not worry about the fact that both properties are still in the LLC's or could this haunt me if the closing goes ok but they catch the mistake at a later date?
