Rentometer is a great tool to use to get an idea of rental rates in a particular areaa. For specific information, I would also look to Craigslist.com. I did a quick search for you on the MLS as there are always some residential properties listed for sale. I searched in Saratoga, Los Gatos and Campbell at a maximum price of $3,000 a month. The search returned 8 properties ranging in price from $1300 to $2500.
The school district that the property falls within will greatly influence the price. Two similar properties in Saratoga can range in price, plus or minus $1000 depending on the school. Saratoga properties that feed into Saratoga schools will rent higher than a Saratoga property that feeds into Campbell schools.
If I can assist with sorting through the information, feel free to contact me. I am a transplant from Massachusetts so I understand how difficult it can sometimes be working through the details when you are so far away.
