Good question! Keep in mind this website isn't very accurate. It's just a big database of info. They get listings through MLS and also public records. It is possible that your home was in "pre-foreclosure"? (Have you missed payments and did the bank file an NED with the county)?
Try contacting the "Help" link (lower right corner) and ask a Trulia rep to have the property removed from this site.... more
Not necessarily. A lot depends on where you're wanting to go. Many agents help a client sell their home and also buy a home home (usually if it's within the same general area). But if you're moving to a different part of the city or an entirely different city, it might be good to find an agent in the new area.
If you're staying the same area, your agent might give you a discount on the listing commission, if you agree to use him/her on the buy side. (Both listing agents and buyers agents typically get paid by the seller).... more
The "market," made up of willing sellers and buyers, determines the final price, and that is the only "right" dollar value. Real estate agents don't determine listing or selling prices, they only advise their principals about pricing and pricing strategy. Some sellers prefer to price low and get multiple offers, some prefer to price high and expect lower offers. The best pricing strategy varies with the local area and changes over time. Comps for residential appraisals and CMA's are usually based on recent sales, not current listing prices. It is unlikely the agent you are referring to is having any material effect on market prices, but rather the forces of supply and demand are affecting your market.
To answer your question there is no practical way for the average person to stop this from happening.
If you were a savvy investor and you thought prices were too low, you would be buying up the inventory and reselling it for a profit.
When you are ready to sell your own property, seek the advice of a local professional, and list at whatever price you choose. Satisfy yourself that the price you ultimately sell for is the right price.
Best of luck!... more
