My objective is for both parties to be treated fairly so that we can grow our partnership with mutual benefit for years to come. 

@Alisa Gammon, It's hard to give a straight answer on your question because I'm not sure the full picture and situation, even though you are explaining things quite well.  

If the mortgage company contacts the buyer about occupancy, they can explain the situation and since they are occupying in 90 days, it should not be an issue. 

You can have several lenders make a single loan and each have an undivided interest in the note and lien secured by real estate.My private lending package consists of a deed with vendor's lien, promissory note, deed of trust (Texas), a business purpose affidavit or personal guaranty, lender's instructions to the title company (because I only represent the lender, even if the borrower is my initial contact), and letter of non-representation (explaining that I work for the lender and paid by the borrower).The State Bar of Texas encourages its members to educate the public on areas of law, and in that light, this is for educational purposes. 

I don’t know how else to explain it to you. when there’s less than 2 weeks of supply that’s the exact opposite of a buyer’s strike  it’s much closer to a seller’s strike if anything  

I would talk to your real estate agent and have him explain the law according to what he knows. 

Even in your personal insurance like home or auto you should always reach out to your agent they will explain what could and will happen.

They explain the process and next steps, I would ask questions, and if their responses made sense to me, I followed their counsel.So I guess the other part of the equation is find someone you trust and then let them guide you in the process.

If you did end up in court and explained that you were going to be three days late with rent, the judge would find in your favor and you would not be kicked out.Your landlord is being unreasonable to not wait three days.

Obviously, that leaves a lot open for interpretation, but that should really be their main objective.
