There was an auction for a condo unit where $125K units sold at auction for $40K which is what I got it for but one time they held an auction for a foreclosed unit where there is no reserve price indicated, was poorly advertised, and no one showed up except the owner and his twin brother.

As a new investor, if your expectation is a minimal monthly loss, but the numbers on a piece of paper have to be spot on, I would again advise caution.  

The key principals are:- Minimize inventory to reduce market risk: Zillow didn't do this. 

If the property has gone up in value and the money is just coming in with minimal effort then refinancing looks like the better option.

You haven't indicated which state this is in but as a general rule, a 24 hour notice is typically all that is required to view the property whether tenants wanting this to happen or not.The other option the owner can provide (IF these tenants are only on a month to month lease) is to terminate such with the appropriate notice to the tenants, get them out one way or another and be done with it.Frankly I'd be more than a little worried about inheriting such tenants. 

The best indicator for natural disaster probability is the cost of homeowners insurance.

Of course, a realtor and a mortgage person are going to tell you to rent one and buy a new one, but why would you move out of your home that you've lived in, just to owner-occupy another single-family that you will probably not like as much, just to get minimal cash flow out of the house you put the work into.

I gotta ask why there's such a delta between the rent billed & rent paid.  110k billed and 63k paid indicates 47k difference, and you're only showing a 15% unpaid/vacancy at 16.5k. 

Sure you pay HoA fees, but as long as you can cash flow, the actual damages are minimized since you only have to care for the interior.

Also know that your LL has to mitigate your damages which means they need to diligently try to release your place as to minimize your financial loss.
