@Kitty Walker- As an investor, I've refinanced multiple Padsplits and co-living properties (where we go direct to tenant without Padsplit), and I generally agree with your last statement, with some caveats:- if the renovation is done well, the appraiser may not even say anything that would indicate it is an "abnormal" SFR (has happened multiple times with me)-the investor may be wise not to make the house crazy- just leave a nice open living room, put double doors on the dining room so it can function as a bedroom now but be easy to convert later, etc.  

Buildium is a LTR platform that what looks to be recently added some STR functionality. 

Third, is that inspectors will often give information about how a home functions and helpful tips for maintenance.

@Alex Stariha Cozy is a cheap option to start with it, but I don't see it being able to scale and provide all the functionality as a true property management software.

The 2 cabins can also function as STRs near GSMNP. 

Once you have a shortlist, sign up for an account with each one and test them extensively to see how they function.

The second issue I have with STNL is that if it functions like a bond, then isn’t this a terrible time to buy?

Secondly, I would shop lenders using the Find a Lender function on BP.

  $50/sqft for a full interior and functional update, $100/sqft for a full gut down to studs, $150/sqft for newcon .If these numbers make sense I would want to visit the property for a true estimate, where it would be line item work scope development. 

Figure you've got the following functions of the house (assuming you've never bought a house before) decide which functions of the house you're worried about breaking and how soon and accommodate for such things.
