Hullo
Regarding ucla housing, here is my 2 cents' worth of advice/suggestion.
If you are guaranteed parking as a dental student, which I think you are, you should consider living in city of Palms. It is about 3 miles south of ucla and takes only 15min to drive to ucla by regular streets, not taking the freeway.
Rent in Palms start from 1000ish for a decent 2 bedroom. A friend of mine is paying 1300 for a 3 br/2bt apt. in Palms. In Westwood, the apts are very crowded, small and right now they range about 2100 to 2500 for a 2br/2bt. My friends are undergrads who are actively seeking housing in Weswood for next year, and these apts are within walking distance but they are very very expensive due to supply and demand.
Brentwood and Santa Monica are a bit cheaper than Westwood, but they range around the same I have been told, the apts seem to be a bit bigger, and Santa Monica is heading towards the beach, which can be expensive. Many grad students live in Palms since they are guaranteed housing, and Palms is a safe area to live. Many undergrads opt not to live there because they can't get parking at ucla, and taking the bus every day can take up to 20-40 min each way, so it's a hassle, but as a grad or professional student, living in Palms is ideal. I have never heard any problems with crimes in Palms, even though it is not as ritzy as beverly hills and brentwood, etc.
Culver City is about 6 miles south of ucla, and also very cheap compared to westwood. A friend of mine lives there in a studio for $470! but that's a rare deal. Culver city is about 10 min freeway, 30ish for regular streets since sometimes there is a lot of traffic on the regular streets, anyhow, I hope that helps, ucla also has an off campus housing office, which has listings updated daily regarding people looking for roomates, rooms for rent, spaces to sublet, etc, i think the website is <a href="http://www.cho.ucla.edu/" target="_blank">http://www.cho.ucla.edu/</a>
and this website has lots of info, I hope this helps
