Although I just passed my state test (yea me) my perspective comes from that of a shopper. I will be buying a home in the next few months so I am not just kicking tires.
Yes, I shop price first. I have a budget I need to follow. I have looked at enough listings within my budget to know what to expect. Properties listed at the high end of my budget that should be selling for a lower price need to have that "something extra" that speaks to me personally before I decide to take on the extra work needed to buy that specific property for market value. If the overpriced property is nothing special to me then I more than likely will concentrate on other properties.
Next I shop photos. This is just as important as price. When I look at a property I want to see, at the minimum, an outside view, a kitchen view, and a bathroom view. An overpriced property with good photos might tempt me to bite whereas a property priced at market value with no photos might cause me to move on. Rational and sensible? Probably not, but it is human nature. Yes, photos can be deceptive. But a good photo of a bad property will cause more action than no photo of a similar property. Also, you get no points for giving it the old college try. Blurry camera-phone photos should never be used. Is that the first impression you really want to make?
Next I read the information. It tells me a lot about the selling agent. You don't need to be Ernest Hemingway but you need to check your spelling and be reasonable. If you can't list basic room sizes and you have only one photo and you misspell something I can only conclude that you are not that interested in selling that property. That makes me not that interested in buying that property or dealing with you.
You have a better probability of securing my business by doing a few basic things that will catch my attention. Of course now I will probably buy an overpriced property with no photos from a lazy lister.
