The information you request is proprietary, but I will tell you that there is no simple answer for you and assumptions are dangerous. Every home, every design, every lot, required street improvements, are all different. Level lots are the least expensive to build, downhill the next, and the most expensive are uphill lots. City design regulations can severly limit what can be built on a particular lot.
Before you even start, you will be out over $100k just to get your building permit.
There is a home being built near the 300 block of Humboldt that has taken the owner 3 years so far and he is still not done. He will be into it over 2 million by the time he is done, not including the lot. I remember him saying that he would build for $700,000; roughly $150 a square foot. It has turned out to be more like $450 a foot for him.
I know of properties that might work for you. Both fixers and lots.
Call me and we can talk more about the costs related to the properties in question. 650.520.7483
