Item 2 seems like it is  1 person day over and item 1 could be a little over but it depends on how many coats and the cut out ect.

Lets not sugar coat it.

It's cheaper but it is thin and you have to apply more coats.

It is sold at Home Depot and I was able to cover some black and purple walls with it in almost one coat. 

The mortar is in pretty good shape and I would not recommend repointing the stone with new mortar. if anything just run a skim parge coat over it to smooth it out and if you're really worried, seal the parge cost with drylock.

I'll second the passive solar heating, especially with the dark/black wall coating behind the glass, and that wall should be generally south facing.

I read the White Coat Investor and Rich Dad, Poor Dad and have fallen down the Real Estate Rabbit Hole!

I'm currently looking into a cosmetic flip there, but just have some general questions about the high desert area.Looks like the property will need a fresh coat of paint exterior and interior, fencing on a 10,000sqft property, and siding/trim replacement, and concrete patio.Any advice or input is much appreciated!

In terms of rehabbing the property, the workflow can range from throwing a coat of paint on a wall or two, to an entire gut of the mechanicals, windows, siding, and flooring.

And it CAN be oiled, JUST oil, no clear coat, sealant coat, none of that that's why I use Ipe Oil ( a little trick).
