So are high prices not an incentive for house builders to ramp up and build more houses? What is the breakdown of costs to building a new house between labor, materials, land, permits/inspections, construction loan burden, etc.? Is anyone working on tech to reduce construction costs of new houses? There are more out-there things like 3D-printing structures. But how about more conventional/mundane things. How hard would it be to have a robot that could lay asphalt shingles and staple them in place? Maybe mudding/taping sheetrock would be not-too-difficult to automate? I'm assuming the raw materials are pretty well automated at the factory (things like sheet rock, 2x4's at the saw mill, plywood, etc.)
