Trulia and other syndicated sites pull data off MLS or public record. If from MLS, this data is put on MLS by your Realtor. In this case , any incorrect data would therefore be the responsibility of your Realtor to correct. Having said that, I see this data was pulled from public record......So it looks like any incorrect data would be a result of incorrect public data. If you can tell me exactly what the incorrect data is, I can tell you how to fix it.
