If a seller understood the situation more, they would push back and renegotiate the listing agreement for an unrepresented buyer.

We were not expecting having to share our loss of rent reimbursement but it was written in our agreement.

Should I have the tenants drop another security deposit for the new 1 year lease agreements even though some of them have been there for 2+ years? 

The partnership agreement determines percentage and partners responsibility and what happens when you disagree.

Further, in order to count the rents from the home that you are living in, it must have 25% equity and you must have a signed lease agreement and have received the 1st months rent and deposit and can document all that. 

Make an agreement to pay and stick to it if she don't pay.

We are in a time-crunch to get our current residence, a single-family home, under a lease agreement as a contingency to purchase our next residence (which is already under contract).
