Dear 714,
I have to agree with Jeremy, it's not easy to locate property based upon it's archetectural style. Lucily, Spanish sylte homes are plentyful in Southern California, so you shouldn't have too much trouble locating them on the MLS> Craftsman, on the other hand seem to be located together, in certain older neighborhoods. In Los Angeles area that would be Venice,Inglewood, and some pockets of Larchmont, and WLA.
I would sugest the older areas of Ontario, as a place to start. Access the MLS with no obligation from my website below.

Since you are looking for a custom/Craftsman home. Just use google to search for "custom Homes". Type in "Custom Homes Corona". This way you will get information regarding agents that sell "Custom Homes" in and around the Corona area.

There are not any "neighborhoods", or areas that have only Spanish Style homes, but there are communities in Southwest Riverside County that have "Custom Homes". Real Estaete sites are not really that detailed in their search criteria.

It's alwasy best to work with an agent who does day to day full time Real Estate business, in the local area you are interested in. Good Luck.

You can find 'Spanish" style architecture in south Ontario. go to http://www.SammisAndSon.com and click on the Orange County home listings. The "craftsman" style will prove to be more elusive.

You're not going to have much luck on the web because most agents don't accurately detail the architectural style of the home. Your best bet it to hook up with an agent that has been around for quite a while and knows the area well as well as the architectual details of each neighborhood.

Good luck,
