Typically these need now to be in a rated shaft and just not insulated. 

Just a side note.. houses in Cupertino that were built in the 50s and 60s many times had NO insulation they just put in two furnaces :) And as you noted they sold for 15 to 25k.. in those days I still remember late 60s when they were crawling up to the 50k mark..

After some research, I've come up with the following:- Blown-in insulation to fill the joists with hard-packed cellulose- Add asphalt panel board layer across the entire ceiling to the existing drywall and fill the cutouts. - Add a second layer of 5/8's drywall to the asphalt board. 

(Tunnel holes in insulation and droppings).

Then insulation, then drywall, then paint primer.

I am not currently using a property manager, so any other extra insulating layer that I can get is useful to me.

Has anyone either upgraded their own cabin(s) or ran the numbers on the costs to improve a ~500 - 700 SF cabin with insulation, sheetrock and heat so they can be rented year round?

It seems to be missing the wood flooring at the moment, but did get the insulation wet and there was a puddle of water under the pipe.

Insulation $5,000.
