I think hard money lender to take this risk cannot legally charge appropriately which means the law is working against you (the law meant to protect owner occupied owners from unfair loans).I agree with @Jay Hinrichs that your best option likely is to sell on the mls.  

At closing you will sign a document that says this will be your primary residence, that you will move in within 60 days and live there for at least the next year.

That’ll be $50.”Document EVERYTHINGLiving with tenants means you see it all—good, bad, and downright ridiculous.

They could include things like waivers for documents and appraisals, relaxation of underwriting standards and money to fund repairs.However, there are benefits for people who just live in the areas, but aren't directly impacted.

Recently, I conducted a cost segregation study on the property shortly after converting to a STR (converted June 1 2024), and I want to ensure I file my taxes correctly and legally given this change in circumstances.

Im no legal expert but belief if you get foreclosed on 2nd home and you still owe money they can come put lien/go after first house.

Lenders will want to see the filed Articles of Organization, an Operating Agreement that you can get from your attorney or, if you're brave and it's just you on the LLC, some people use Legal Zoom or Law Depot.

Ensure your mortgage lender is requesting documents upfront early in the closing period so there is no last minute suprises3.

As a backup plan, if I have to go with a local PM company that only leases the entire home, could I use an addendum to add additional tenants to the existing lease while ensuring everything is legally structured?

Do not rely on it for legal advice.
