The week in Diamond Bar
What moved, what dropped and what changed hands in Diamond Bar, read the way an inspector reads a house.
The Diamond Bar file →The largest reduction on the desk was 2646 Castle Rock road — down $341,000, from $1,490,000 to $1,149,000, listed by Pinnacle Real Estate Group.
12 listings changed status: 5 pending, 4 sold, 2 active under contract, 1 coming soon. The brokerage on every row below is the listing brokerage on the record, not ours.
9 homes came to market, asking from $375,000 to $6,500,000.
That is the week, address by address. What any one of these rows means for a house on the same street is the question the file answers next.
