The 1 mile income radius could be misleading in either way to the positive or negative if the property is on the right or wrong "side of the tracks" so to speak.The 80% occupancy, if it's solely due to the mismanagement of the current owner could be an opportunity. 

@Chris Seveney @Nathan Gesner The owners offered to cancel their lease and return their security deposit in full.

However if you are looking at commercial properties a lot of them will be owned by corps and then it will still be hard to find the actual owners!

@Christopher J Driscoll did offer some great insight from his experience with ADU's as an architect and property owner.

I am a property owner in Brazoria County Texas. 

What are other ways to get this property with out having to owner occupy, FHA, conventional?

If you are able to manage it yourself, I think you will get a lot of very helpful education in real estate by spending a least a year or two doing that.You'll be able to work with property managers a lot better if you've done the work yourself for a bit, and it also helps to get familiar with the various laws and regulations you have to comply with as the owner, even if you do have a property manager in place (e.g., the new RI rental registry and associated lead paint inspections/certificates).It's up to you whether you're able to do it, but I think you'll get a lot out of the experience if you can try it for a year or two.

Also would need to know if the property would be owner occupied or an investment property. 

If was originated as owner occupied in the past and no longer is owner, if you have change of name on deed or insurance, if impound had a dispute, claims - are a couple reasons why the servicing changes.

The owner is friend of mine, really good dude.
