I am sure a lot of homeowners incorporate laser 3D house measuring when they look at a property.
But can you quantify them? Especially in rural areas, unique properties, etc. The answer is no. False accuracy is still false at 3 decimal place "precision".
If a computer can do all this then the appraiser is pointless. Hire a quant. It's the appraisers judgment that counts. CAC - all this invites is a Computer Aided Catastrophe
The difference in an efficient market (cars) and an inefficient market (houses.) No matter how much quantification occurs, no computer is going to make an inefficient market efficient. Dissecting a property via quantification of all the aspects is a glorified cost approach and no more accurate than a well prepared appraisal.
Hybridization is certainly not going to increase the accuracy of the estimate nor improve the skills of the appraiser who will be put on half rations or less. This is all about the urge to eliminate the one firewall that prevents banks from swindling millions of homeowners be it a perfect system or not. Without a doubt the desire of those promoting the hybrid are seeking to eliminate the appraiser and the one possible source of preventing a sale - any sale at any price- from going through.
Once prices collapse we will see a huge transfer of wealth from the average homeowner to the banks and proponents of this stupidity.
