This really depends on the specifics of the home. Overpricing from the start can often lead to a situation where a property sits, and sits, and so buyers and agents alike lose interest. If a home is priced correctly, you could end up with multiple offers, and a sale price much higher than you would have gotten had you listed the home high from the start.
Atwater is a hot neighborhood so if a home is priced correctly you could get lucky and receive offers in the first week.
Best of luck!
