Note you have two problems:
1 - features that you can't observe (sentiment / how much someone likes the house or area);
2 - features that are too expensive to observe
Have a view of the ocean? In CA, that can be worth another $X00k or maybe even millions. Have ocean view rights, ie nobody can build between you and ocean? Even more. The neighboring property with a blocked view can be worth far less. That's going to be really hard to observe at scale.
Does the backyard, if any, get full sun? What is the soil like?
Have reasonable suspicions there's asbestos in the building, even if not formally acknowledged, and a $50k+ remediate would be required?
How much sunlight does it get, and from what side?
How old is the interior woodworking and how well has it been cared for?
How good is the internal soundproofing?
How much renovation is required? Do you still have knob & tube?
Even silly things like how good is the cell service. Which can vary just by moving 30 feet.
How good is the water pressure and how much $$ would it cost to upgrade it.
You could run a computer vision algorithm on the included photos to get a sense of the view. If a house has a good view they're going to include a picture of it.
