I totally have to agree with adding your asking price. People who don't add an asking price drive me crazy. When I search for horses who are under $6000, I want horses that are under $6000, not $200 000 horses that just don't have a price listed. When I search horses over $10 000, I don't want to miss out on horses in that price range because they are listed as $0 or $1 and don't show up in the search. I always just pass over ads with no price. I don't like playing that game. I also typically pass by ad's that indicate that the price is firm, not negotiable. I am more likely to respond to a photo add, but I won't not consider a horse just because it has no photo. Generally most people won't even look at horses without photo's because if the owner can't take the effort to put a picture on the add, they might not take the effort to properly care for the horse.
I like to know the horses quirks as well, but generally if I see soundness and problem in the same sentence, I close the add right then and there, because if the person tells you that much about the horses quirks right off the bat, I can only imagine what they aren't telling me...... Obviously not all people play games like that, but the people that do make it really hard to sell a horse completely honestly. I'm constantly buying and selling race horses for clients, so I'm fine tuned to assume the worst about a horse until proven differently. Its a guilty til proven innocent policy, but my clients rarely end up with a problem horse
