Setting a realistic market price for a property is most important if we plan to move it in a reasonable amount of time. Sometimes coming up with a CMA from our local MLS system info is a challenge when there has not been a lot of activity in a given area and we have to go research further into public records with the county. We also need to avail ourselves of using the open house to view properties and be knowledgeable in comparing what competition is out there. Appraisals can also be helpful, but I fear that sometimes they are "shopped" and tweaked to suit the owner. . . .
Thankfully, I believe more & more homeowners are realizing they need our help and we are seeing less FSBO's in my area. To increase the exposure we have to explore the most effective means in marketing the home to more potential buyers. I have begun putting spots in the classified section of our local newspaper and found that to be effective and not very expensive.
But in summation, sometimes we have to sit down with a Seller and just say, "Here's the Deal." If you want me to spend advertising monies & my time to creatively market your home we have to be competitive with your competition. If a Seller ignores your advice and wants to put their property for sale at an overpriced amount, perhaps our passing on the listing may occasionally be the wisest move.
No use spending money while misleading a client if you don't think you can sell their home. I think it is unethical to take a listing that you know isn't salable.
