Invest in one local (SoCal) property or Multiple out of state?

[Christina Kim]

My husband and I have only done one deal in the past year (out of state), and we want to crank things up and get more things happening. We've been able to save enough to do something in the Southern California market, but realize our buying power with the capital can get so much more elsewhere. 

We want property in Southern California so we can have hands-on experience with management and have more control over what we buy. However, we can get more doors elsewhere.

Writing this down makes it seem like a clear choice that getting more units would be the right choice, but would there be advantages in getting ONE deal in SoCal over multiple smaller deals out of state?
