Information as such should be the responsibility of your Buyers Agent, he/she should provide you with a detailed account on how much all expenses should be on your property. as far as Trulia is concerned, this is just a vehicle that pulls from Multiple Listing Serviece or "MLS". So Listing agents should be more diligent about what information is being put into the system. My Professional recommendation would be to reach out to Qualified Buyers Representative, or buyers agent, to help you through the ups and downs of the home buying process.
All the Best,
