It is Trulia, I'm an agent and since i registered on their site as an agent they are trying to contact me to sell me ads.
I'm assuming they are trying to use local numbers to make it seem like they are from the neighborhood.  I find that very deceptive.
Next time they call I will ask where they are calling from to see if it's a legit local rep.

It's Trulia trying to sell advertising, very annoying I told them no and they still keep calling. I will have to block that number

This is a TRULIA phone number.  SCAM.
BEWARE. DO NOT EVER GIVE TRULIA YOUR CREDIT CARD NUMBER.
If you give them your credit card number, they will keep making unauthorized charges every month. They will say that you subscribed to their services when you only paid for a one-time service and then they will refuse to give you credit to refund your money.
This deceptive, unscrupulous, unethical company is like a leech.
The only resort you will have is to call your credit card company to lodge a complaint against Trulia and change your credit card number.

Trulia also uses 646-346-6848 for display number on caller ID.
