Yes there is, however the competition is extremely high in this price bracket. We work at finding properties which are NOT on the MLS, Truilia, Zillow, etc for our buyers. Contact if you are serious about finding something.
I'd be happy to set you up on the San Diego County MLS VIP notification for those zip codes if you send me your e-mail address. My website is http://www.SanDiegoNorthCountyLiving.com. There is also a downloadable SmartPhone App if you would rather use that...just go to that website on the lower left column. I'm here to help!
The sort answer is yes. However "decent" is an arbitrary term. If you would like I can send you some listings or you can use the search feature on my website to see what is currently on the market in those zip codes.
I would be glad to work with you to find a home that meets your needs,
