I'm sure a lot of people here work or live in the area. I assume the tech bubble is 99% the reason the real estate there is going through this huge bubble increase and when the tech bubble goes I assume the housing market will follow.
Is there any signs this might be coming to and end or is it still growing at an unsustainable rate (in regards to the tech industry or the housing market).
First, you're assuming that there is even a tech bubble in the first place. Many of these companies have solid revenue and worldwide reach including Uber, Lyft, Twitter, Airbnb, Pinterest, Zenefits, and many more. Is tech overvalued? It probably is. Is it a bubble? No one knows but it isn't like 2000.
Second, you're also assuming that there is a housing bubble. It's not really a bubble ready to burst if people are paying cash and owning the place outright. This isn't the same as 2008.
If I were to break down the reasons SF real estate is nuts, I'd say it's something like this:
-25% Tech Money
-25% from foreign buyers such as Chinese
-20% Low interest rates makes buying cheaper than renting and creates easy money
-15% from people saved up money during the crash and is now ready to buy
-15% from just a really good overall local economy
Someone else mentioned that the recent Chinese crash might cause more investment into Bay Area properties as a safe haven.
I think the market will slow down in 2016, maybe even flatline in growth but it won't "crash".
