Los Angeles Home Builders Question - cost per sq ft

[Mosun Mah]

Hi Contractors and BPers, 

What is a good "binding bid" estimate to build a mid-century modern single family home in Los Angeles with quality materials? And considers overhead and contractor profit? Not luxury, but very good quality turn key home.  Finished kitchens, baths, hardwood floors, plumbing, wood windows, wood beams, etc.  

• $125 a sq ft?

• $165 a sq ft?

• $185 a sq ft?...more?

Thank you in advance,

Mosun
