We live in a $1.1 Million home

We live in a $1.1M home

A friend told me about Zillow. We entered our address, which in turn revealed the estimated value of our home and that of our all neighbors. However, it's probably outdated or not accurate since my landlord hasn't had the house appraised since the upgrades/renovation. I wonder what the original value was when it was first built. Other friends informed me that the selling price of a house is public knowledge, available at the City Hall, but I'm not that curious. This is public knowledge: Real estate is crazy in Cali.

Zillow stats for current home:

• Home type = Condo
• BR = 3
• BA = 4 (but actually) 3.5
• Zestimate = $1,067,164
• Home = 2,065 sq ft
• Lot = 1,686 sq ft
• Year built = 1980
• Date sold = --

Zillow stats for previous home (a few blocks south of me in Hermosa):

• Home type = Single
• BR = 4
• BA = 4 (but actually 3.5)
• Zestimate = $1,480,254
• Home = 3,401 sq ft
• Lot = 2,500 sq ft
• Year built = 1989
• Date sold = 09/28/04 (I moved out 05/01/04)

Note: I know my late landlord of this previous home had originally purchased it 10 years ago for $550K and the asking price was $1.325 Million in 2004. The new owner has renovated since 2004, so I can believe that it's worth at least $1.5 Million today.
