Home renovation costs in Bay Area

[Deepti Mandava]

Hi - I am a single mom trying to buy a home in Bay Area. Due to budget constraints, mostly targeting fixer uppers and found one in west San Jose. I am looking at a new roof, internal configuration changes and addition of 1500sq.ft. Want to get a sense of costs and what’s the best price per sq.ft and how I can optimize on the costs. Any thoughts / guidance / contacts wld be appreciated.
