Typically there is softening of activity after schools start, mainly because both sellers and buyers have made their choices and are not looking to uproot their kids in the middle of the school term. While there is some change in prices, there is also less inventory on the market, reducing your options.
A good way to gauge it is to review comapratives and analysis for different time periods. Even if you want to purchase a few months down the road, this would be good time to get started. It will take you some time to understand the market, see what is available and solidify your preferences in a home. I have lived in Cupertino for the past 10 years, and work in Cupertino. My kids attend our fabulous schools, and I can assure you that (given the swings in the market) this was the best investment we made.
Give me a call or send me an email, I will be happy to provide you further information and help you find best value.
