You would have to determine if the website/ads are really creating constant traffic and value that needs updating/attention.

Came back parked in front of the house at night to see the neighborhood and traffic it got.

As @David Affonso mentioned depending on where you are going, traffic on 101 and 280 can be rough.If she is north of 92 (San Mateo/Foster City) she can look at San Bruno/Daly City/South San Francisco/Pacifica.

(And a great experience for young drivers to spend a morning in traffic court.) 

I won't miss the traffic (although I-95 in Boca Raton is no picnic).

Question - why do you like the extra phone traffic from prospective renters when you don't have vacancy?

Create or pay someone from Odesk to create Pay-Per-Click campaigns to drive traffic to the websites.

What are the traffic counts and how easy is it to get onto the property from the other direction?

Certainly you should expect quick responses to your questions and should be updated regularly on the level of showing traffic, but that's noise.

There are more jobs in MY IT specialty there and for a higher wage than is typical here with a far lower cost of living and less traffic.
