I made a few changes based on the advice that I received here on Bigger Pockets and got three applications.

For a co-signor we require a full application, screening and 4x the rent

Unfortunately, the pandemic pulled the rug right out from under us as we were in the middle of the application process with Visio.

Applicants can view properties without scheduling, after hours, and on weekends or holidays.However, the lack of human interaction does come with a price.

Be very clear that they must transfer the deposit along with a complete set of tenant records (application, lease, payment ledger, etc.). 

I've heard that you might need a hard wired fire alarm system, but haven't heard of needing a supression system, I thought that was only for commercial buildings or restaurants, but I think I will fill out an application for variance and see where it goes?  

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

Fix it properly, then rent it out to a highly qualified applicant. 

Quote from @Max Smetiouk: Quote from @John Malone: @Ryan Leake Id agree with others, it is not a loophole, rather, the correct application of the law.

So if the appraiser determines for example that the average rental amount for the area is $1,500 then the mortgage, taxes and insurance (and HOA if applicable) need to be at or under $1,500 to get the most favorable terms.
