As a retired realtor, this is a tough question because you need to learn the hidden agenda of realtors. Any licensed realtor will tell you "now is a great time to sell" because you are paying them a commission fee = a paycheck to the realtor. Realtors will never tell you to wait 6 months, 1 year or even 3 years to sell because that means you are not paying a commission and that realtor is not getting paid.
Therefore, the better approach is to have a realtor tell you what similar homes to yours are selling for in your neighborhood and make sure to tell that realtor you have NO intention of selling now. Then wait several months and have the same realtor give you an update on the market. Wait several more months and another update. Now you will have the market trends for similar homes to yours in your neighborhood.
By the way, it takes less than 5 minutes for a realtor to give you comparables to your home for market trends. They just need to type in the information in the MLS and within a few minutes you will have your printout.
