In my county, you can do 1-3 types of appeals - electronic, in person informal, and/or formal. I go every year. We only have custom homes in our neighborhood, so the build-out levels are different from house to house, they would only compare houses with similar build-out, but you can appeal and show proof to convince them to change it too. I do a lot of research every year to compare and bring my research to them.
If this is your first year in your county, you probably want to try everything you can. First year, I did electronic, they rejected my offer, so I went in person, they also said no because it was our first year in our new home, so I went to the formal one and was able to convince them to lower it a little, not a lot.
You have to look at your surrounding, not just your house, and your house also, and the houses in your neighborhood and compare the prices and quality of the materials used, and if there's a ditch next to your house or something else that you think may decrease the value of your house. I walk around my house inside and out, take notes, take pictures. I also walk around my neighborhood and do the same. Bring all of the reasons with you when you appeal. That's what I do every year, I run a business and I have a kid as well, but I make time for this, I do go very early in the morning. This year I didn't do so well, I was only able to convince them to take off $52k, last year I was able to do $62k. Every bit helps. I have a neighbor who was able to get them to take off $90k!
Good luck!
