I have to echo the sentiments of my colleagues on this one, and further to emphasize Dave's point that if you believe poverty is an indicator for crime, then you will never find the home you want.
To be frank, Ponderosa Park is a beautiful section of Sunnyvale, and there are some fabulous homes in the area! I just negotiated the purchase of a home in the Ponderosa area for my clients--a 4 bedroom 2 bath property with 1800 square feet--that they bought for under $800,000. The community is quiet, the homes are well maintained, and my clients are extremely happy with their first home purchase.
When looking at any property it's very easy to find negatives about the site that discourage any buyer from buying, well, pretty much ANY home. It's the savvy investor and buyer who can weigh the positve and negative aspects of an investment, while eyeing the value of the asset in the future and studying current and past trends to extrapolate the return. While schools, crime, and the home's intrinisic characters will most definitely influence the value of the home, I've never drawn a conclusion that communities with lower median incomes necessarily are always linked more closely with crime.
As the others said, before you "turn yourself off" to very good investment possibilities, you might review the crime statistics in the area to ensure that the neighborhood meets your personal requirements for safety. I think you'll find that even the "safest" neighborhoods will have crime. You need only to determine what is acceptable to you.
