I read the findings you're summarizing differently. Insane prices already indicate that a market is completely defective. Correcting that condition requires, as noted in the figures, ORDERS OF MAGNITUDE difference in either the demand or supply. When rents are that crazy there will be an already displaced mass that isn't seen in the focus area of study; the market needs radical, organized, and planned (at least in the broad strokes) re-classification and re-organization of zones. As a very rough back of the napkin approach, which an actual expert would probably have better initial numbers for, examine the quantity of jobs in the area. To approximate for youth, students, retirees, and the unemployed; double that figure. (Est) NUM_RESIDENTS ~= 2 * JOBS Then assume by the time you actually get things fixed the problem will have gotten even worse. So target the overshoot at an additional 25 to 50 percent. Also, require distribution of housing VERY ROUGHLY according to actual census data of demographics. Just based on the cost of rent I'd say NO PLACE builds enough housing for singles nor enough for 'large families' (not in houses).
