An LLC with 2 +members does normally require a 1065 filing. 

I have been told by a contractor that the foundation of the building is intact, so it does not need to be torn down but requires a "gut renovation down to the studs."

You want a design that stays relevant, withstands high turnover, and doesn’t require constant costly updates.7.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

There are a lot of ways to meet the requirement 

STRs can bring in higher revenue but require more turnover, guest management, and keeping up with regulations.

Most lenders require the delinquent balance to be paid before approving a VA loan assumption.

This will affect things like required down payment, rates, and even which lending institutions would be willing to finance. i encourage you to look up warrantability for financing just so that you don't have surprisses when your 20% down buyer cannot finance that way.

I recommend you send notice earlier than required and by multiple avenues to verify receipt.

These are all solutions that don't require expensive treatment, therefore they are useless to adding to the profit of the hospitals.
