I'm not positive how Trulia pulls it's public records, but it appears they are pulling the public data from 2011. You current accessed value is $195,200. If you claim your own property on this site you might be able to edit some of the information about the home, but more than likely you won't be able to edit tax data.
Is there a specific reason you care what it says? Your tax assessed value really has absolutely nothing to do with the fair market value or an appraised value. If you're concerned about your home appearing to be worth more then I wouldn't sweat the tax assessed value. If anything it's just showing that you taxes are higher than someone else with a lower assessed value.
To comment on your property and which neighborhood it is in, its legal description from the public records does indicate that is is part of South Creek. Here is your legal description of your property:
SOUTHCREEK SEC 1 PT L4 BEG NE COR L4 SW 113.10' TO COURT SWRLY ON COURT 111.18' NW 71.76' NRLY 80.29 ' E 209.5' TO BEG 15,964SF
If you can't edit these details yourself if you claim this as your house through trulia you may have to call them to find out how. Since there are no past listings on this property, wrong data on an incorrectly entered listing can't even be blamed.
