Hello Patrick,
I am also an Arizona agent and will share my thoughts with you on this.
All you can do is have conversations and good communication upfront. When someone, either a flipper or regular seller, says "Just to see", this is your opportunity to educate them on the error in this thinking/decision. We have seen that even in the last couple of years with extremely hot market conditions, the priced too high "just to see" strategy didn't often work for sellers. In fact, in my experience, homes that were priced accurately or somewhat "low" is what really created the frenzy that drove extreme competition. The "just to see" strategy tends to only result in price reductions and actually could cause your seller to actually leave money on the table because it's now sat on the market for longer than others. Sellers often think, when they get offers right away that they are priced too low, which actually isn't the case. Buyers ultimately determine prices for property, if no one is making offers on the home, that means buyers view some part of the house as unattractive, either location, condition, or price. If offers come in, buyers are seeing it as an acceptable property and thus are interested, not necessarily because it's too cheap like most sellers fear.
As for being an agent, you have to respect your time, and investment in the sale of these properties and be willing to let an unreasonable seller go. If you agree to their terms knowing they are most likely too high or not correct, you not only do a disservice to yourself but also to the seller. So sometimes it's okay to say no to a seller and walk away if it ultimately results in a home that is overpriced and not going to sell. You are supposed to be the market expert, so be the expert, present the info, and if your sellers are close to alignment then off to the races! But if your seller is unwilling to see the facts and wants to "just see", I personally would consider not taking the listing.
My two cents. Best of luck to you!
