I have $100k in appreciation to date.

This log should include:•The date of activity•The property worked on•Specific activities performedExamples of activities that typically count include approving tenants, setting lease terms, handling repairs, and other hands-on operational tasks directly related to managing the property.

I also keep track of the date payments are made.

If the credit items reported are up to date with no late payments that is generally good enough for me.

She messaged me saying she is signed in, but needs me to change the "due date" to the 3rd because that is when she gets paid.

I would hope that OR and other PMSs would just block dates. 

They typically do a soft pull close to the closing date to ensure there are no new debts or significant changes in your credit profile.

Units 1-7 are rented out at $725 on 12-month leases (although I have not gotten the expiration dates on those yet), and Units 8-9 are not completed but are slightly larger townhomes than can be renovated and rented out for more along the lines of $850-900.

It is delinquent enough (Greater than 90 days but below 120 days(can't file first legal until after the 120th day by federal rule (Except under very very specific circumstances)) to where the lender or servicer has sent the breach letter (Notice of pending foreclosure) with an expiration date that the loan will be referred to a foreclosure filing (Trustee/attorney) if the borrower(s) don't cure the breach within that defined period of time.* A notice of default is not a letter sent by a creditor saying they are late.
