First of all, the address is an office building in Rancho Bernardo. We happen to be land and new construction experts and what is being offered at the price of $359,000 is not possible in Rancho Bernardo. We Googled the company and what they are offering is in Lancaster, CA which is in the Antelope Valley way north of Los Angeles.
If you are interested in something like this in San Diego, we would be glad to help. Please know to expect a minimum finished cost of $600,000 to $650,000 for a 2,100 SF home.
Best of luck,
