There could be 1,000 reasons why these cabins don’t have more bookings (location, price, decor, etc) 

There is commonly opportunity to do that through minor cosmetic and decor fixes.  

We ultimately purchased 3 standard precut slabs from Floor and Décor for $480 and had a local fabricator cut and install them with an under mount sink for another $975 in mostly labor costs and it turned out great. 

Thanks in advanceWe have gone with both Sherwin Williams (they have the contractor paints in the back) and Home Depot, flooring we have done Floor and décor for tile, We have found good pricing on flooring on some of the Lumber Liquidator items.You can also get the Home Depot pro desk to match or beat pricing if the order is large enough

I have done my own installation one (1) time using prefab granite slabs (purchased from Floor & Decor) and did save alot of money, but it took two full days for me and my wife to do the installation (the undermount sink took forever to cut and polish).  

For the painting portion, I would highly recommend talking to Jim Prater at Chattanooga Paint and Decorating.

More than a few investors do nothing but rent themselves and spend the money that would have been spent on a mortgage and decorating on rental property. 

I consider the fireplace more as a decoration than a heating unit.

This should explain the quality of appliances we choose, carpets, and other decor.

That is slim to buy and decorate a STR.
