These are some of the areas that I monitor as well. A few indicators that I watch are # of sfrs under 400K in 92104 and # under 500K in 92103. Both of which have skyrocketed in the past 3 months.
Also, the condos in 92103 inventory is thru the roof. There is probably 70 or so new units just sitting empty and another 187 coming by september over at Atlas. The condo situation is beginning to resemble downtown’s. Looks to be 15+ months supply and rising if they actually listed everything availble.
