For $300,000, there are some areas of Oceanside that are nice, and others you would want to avoid. I am an agent whose majority of business is in Oceanside and knows the neighborhoods. Plus I often work with first time home buyers who end up being repeat clients, or referring more business since they sense I really care and will not pressure them to make a decision. My website includes some testimonials and lists homes which I have sold representing the sellers. Today, I am about 50/50 with buyers and sellers and would be happy to help you with your special referral.
You can also check out my other answers on Oceanside real estate in Trulia or my Activerain blog(where I am #2 in Oceanside) to get a better feel for my professionalism. http://www.trulia.com/voices/profile/Real_Estate_Pro-Carlsba and http://www.activerain.com/tonycannon
Steve and I did 19 transactions in Oceanside last year, and we'd be glad to talk to you regarding a referral. You can reach us at 760-685-8877, or email@example.com.
