You can figure out their rental history from public records using beenverified.com and/or your local court websites.I usually just do the latter; If they don't have any rental judgments or a criminal record then that is usually a good sign and if they do then you might want to think twice.

An abstract can be done by an attorney, they can bring the history of the title to date, but a title insurance company will want that performed by an agent or an attorney approved by that company.

To me that means that I lend to just a small number of people I know and have history with.

I agree with using an attorney to review your custom lease document.

Also know that you are entitled for a free credit report from the 3 major agencies each year just go to annualcreditreport.com this may provide some insight into your current.Just wondering where is your credit at now, range wise do you have any credit history, if so is it negative history?

Every loan officer on the planet is going to tell you to "build good debt" to replace "bad debt" or a non-existent credit history. 

But with no documentation you may loose.

-Do you know anything about the history of the hotel, when it was built what flag did it carry, what flags has it carried over the years etc.  

All lenders have a due on sale clause in their loan documents, but as long as your current they never use those if you transfer into an LLC a trust etc.

Connect with a local realtor and ask if they can provide you with a history of the property to see the last time it was listed/rented.
