Expect to remodel kitchen and baths and put new floors down, paint, knock down a wall to open the floor plan. 

The only big issue I ran into is on of the basement walls needed extra support, I don't think a newer build would have that issue. 

(all the colored dots are clicks from my traffic.

This seems pretty clear that LL gets to select the area(s) to be painted and the color.  ”The areas designated for painting should be painted thoroughly to ensure that no previous color is visible.

Use of Euro-style wall units for air-con.. 

In our student houses we use a programmable thermostat, but our building monitoring system has its own sensors and can override the wall thermostat and will not allow the temperature to get below 10C (50F) ... we are presently testing a new software load that will also prevent them from cooling the house too far in the summer.

However the thermostat is mounted  to the wall a few feet from the front door in a highly accessed retail store where the door is constantly opened.

For example, the 2nd to last photo of a random wall and floor with part of open door; what is that supposed to be telling?

They are far more common now and harder to find models without but:1) these add cost to the purchase price2) they don't bring a lot of value3) they can leak or detach and damage the propertyI own around 50 doors and I cap off the line at the wall or in the basement with a valve and a cap so the potential for leaks is 0.00001% :-) 

Sorry for the long winded back story, but end game is to put a A frame on the existing 20x40' stem wall above near where I"m standing, and put some stairs into a drop down area below for chairs/fire-pit overlooking the river canyon below (but out of view) under where the drone is flying.
