I'm sorry that your question has gone unanswered this long.
If you are still interested I would highly recommend using Trulia's crime map to view the areas crime history.
You can find it at
then click on the upper right side the pull down menu for San Diego. Next drag the map to the North County section that you are interested in.
If you roll over the dots it will show you what kind of crimes have occurred near there.
I am familiar with the greater RDO/Ivey Ranch region in Oceanside and it has been considered desireable and safe by my clients.
But please note that Real Estate Agents are discouraged from "Blockbusting" particular neighborhoods with negative remarks and they are discouraged from "Steering" clients into specific neighborhoods as well - so it's sometimes an eggshell subject when you ask about "safety".
If you would like more local advice - I would be happy to speak with you. Welcome to Southern California
