I disagree. In that part of CV there isnt anything on the market today with at least 4BR/3BA and 2400 sq ft under $950,000.
There is a 4BR/3BA/2 car gar 2438 sf home with 1200 in Mello Roos in escrow with a range of 850 to 875 that sold in 4 days. My guess is they got 875K.
There is a 5BR/3ba/3 car gar 2828 sq ft in escrow with a range of 899 to 999 that backed to a pretty busy street (Which is a KILLER!) and sold in 94 days.
There is a 5BR/3.5ba/3 car gar 3109 sf in escrow with a range of 950 to 1.05M after only 11 days. My guess would be $1M plus.
All these homes are at least 15 years old, in nice condition but minimal or no upgrades and small lots.
There is very solid demand and very little supply of homes like your friends in this marketplace today. With 5BR/3BA/3 car 2600+ sf and no Mello roos there house would sell for at least what they paid in my informed opinion.
