I'm an inactive licensed, Florida real estate agent. I've turned this over to my wife to answer, who is a Broker, and has been an active Realtor for 38+ years. She's got too many Realtor designations for me to keep up with, but she's a straight shooter, tell it like it is person. Her answer is below.
You definitely want to talk to more than one Realtor, and you want to make sure you use a Realtor. Everyone who sells real estate is a real estate agent, but NOT all are Realtors. Realtors have to abide by a Code of Ethics. If you have a complaint, there are options available to you.
The best place to start looking for a Realtor is among your friends. Who did they use, were they happy and why. Outside of that, I would go to
Find a CRS. CRS stands for Certified Residential Specialist, a designation only about three percent of Realtors nationwide have. If you want the best of the best, that's the ideal place to start, and the search is available to the public. It's one of about seven national and international designations I have. This one has to be renewed yearly with coursework to keep it, and it's not an easy designation to initially obtain. Once on that website you can search by city and state, and read bios of the agents plus it has contact information for them. Many agents will also list their specialties...i.e. vacant land, acreage, luxury homes and what specific communities or counties they serve.
Concerning online reviews, don't believe everything you read. I'd rather work with a Realtor who has four to 20 reviews, than one with 80 plus. In this day and age, I've heard many woes of paid reviews.
I'd also suggest doing a bit of research on your own. I'm not a fan of Zillow, but compare the estimated value they give you with what your county tax rolls say the property is worth. Look at your latest tax bill and it will at least give you assessed value, while many will tell you estimated market value before talking with Realtors and reviewing their comparable market analysis (CMA) reports. You also want to know how your property is going to be marketed/advertised. Does the Realtor provide updates on market activity?
You also want someone you feel comfortable working with...that personal relationship where you feel you "click". Just keep in mind too that anyone can tell you they can list it for X price, but can they sell it for that price? You don't want to have to keep lowering the price.
Depending on the market place, many areas experienced a slow down in sales because of interest rates that nearly shot up to 9 percent, now in the low to mid 6s depending on credit. So how long a property has been on the market (called DOM) may not be as signficant nor how many listings a Realtor has. Some areas shut down, some slowed to a crawl, and others moved back to a market where it takes nearly five to six months for a property to move. Lastly, is the Realtor you select going to be the one in contact with you all the time or is it going to be a team member, and you only see the iinitial Realtor again at the closing table? Hope that helps. Diana
