Cost Estimates Question in Northern California - Help!

[Sasha Josephs]

Hi!! Green investor here and wondering what you more experienced investors/flippers/builders/etc. are seeing right now for new builds and remodels as a rough $$ per square foot in the Tracy, CA area? This is in between the East Bay Area of California and Manteca (in San Joaquin County).

Separately, and more importantly, what can be a rough cost to abandon a well and septic system and tie into city services (I've confirmed that there is a 12" city sewer and a 12" water line running along the street in front of the property with the city). Water meter is in the driveway, septic is in the back of the house.

Would be very grateful for any information.
