Appreciation is never a guarantee, and it's a complex issue with many factors that contribute.
In general, a single family home will almost always appreciate faster than a condo, unless the condo is amazing, unusual and something highly valued - like a crafstman that has been condo converted.
A very important factor in looking at appreciation in a property is the neighborhood. Are there homes nearby that are higher priced, in good condition, generally desirable? Is the neighborhood "up and coming"? Is there something being built or planned that will elevate the status of the neighborhood - for instance the way Berkeley Bowl did for West Berkeley?
It's good to educate yourself about neighborhoods by researching as much as you can in advance. Then, in this real estate market, with so many people looking and so little inventory - be ready to pounce with your best offer when the right property comes along.
