I apologize if the image associated with your property page caused you any inconvenience and I am happy to provide some insight on this. When a property is off market, the default image is provided to us from Google images of which we do not have the ability to edit or remove. Off market homes do not appear in general search results, so anyone browsing for listings in your area will not come across your property page. The only way to find your home on our site right now is if someone were to enter your exact property address.
Please be assured if you are intending to sell your home in the future, you (or your agent if you choose to use one), will have the ability to create a new listing with new photos, and submit the listing to Trulia.
The new listing will override the off market property page with the Google image photo.
However, if you are wanting to pursue this incorrect image further, my best recommendation is to contact Google directly to request they blur out the home. This change will translate to your page on Trulia. I understand this is not exactly the resolution you were looking for, and I do apologize for that. Here would be the steps if you choose to go this route:
From your Trulia property page, click View Map on the bottom right of the Google image.
Click Street View.
Click Report a problem.
Fill out the form and click Submit.
