I am going to put this as bluntly as possible:  Condominiums in the Smokies are not good investments.

Not likely), vacancy (@ 8% for me), and a possible PM (10% normally).I recommend you reach out to a local seasoned investor and have them run your #s with you, as the #s depend on how you manage it (how hands on you are) and also local pricing.

So outside of licensed electrician, plumber etc I ended up doing as much as possible myself, 5 hours every workday night and sun up to sun down on weekends.Looking back this was a huge adventure for me personally, it took me 2 years, I learned a lot and it made me a better investor.

Understood I made a bad move here as this was first investment so didnt think much except at the location for longterm growth or possibly I move there as part relocation.

I appreciate you hitting on all the potential possibilities in detail. 

You can use the Bigger Pockets management finder tool to look up MTR management companies in the area and then I have a few recs I can provide if you are interested.Shoot me a message if you would like to discuss further and I can help you strategize to make sure you make the best decision possible!

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Your time is best spent producing the revenue that allows you to invest in the first place.That includes using local agents you meet and feel are a good fit for you, property managers, possibly buying completed properties like the one you posted here, and outsourcing as much of the process as you can as you get started. 

Depending on the state, up to 80% LTV is possible.

So I would suggest keeping your STR property geographically close and doing as much as possible to keep your profit% high as possible.As far as the actual house you use, I would just say - be honest, be fair and strive for the best area, most amenities, cleanest house, best communication, and any other extras you can get.
