If you are moving to San Diego and plan on taking a trip to shop for your dream home, consider renting a car. There's nothing more convenient than a car (hence its greatness in America), and San Diego is one of those "car cities". The public transportation system in San Diego is ridiculous. Trolley only goes to several parts of town (most likely not anywhere close to where you are moving) and the bus lines have anywhere from 30-minute to 2-hour waits.
If you plan on getting around town and seeing several places a day, public transportation in San Diego is NOT the way to go. To top it off, the cost of 6 bus transfers will cost the same price of a cheap rent-a-car from Renty.
Save yourself time, money, and from headaches. Rent a car and find that home of your dreams. You'll be happy you did.
