Hello @Valente Sosa!
@Jacob Ghena does bring up a great point! Why not work with a Realtor?
You want your property to be viewed by the largest buyer pool and although saving 6% in commission sounds great you would lose a large portion of motivated buyers because your property is not on their agent's radar. Also, when a homeowner sells a home on their own they are usually responsible for providing the buyers agent commission of 3%. So in reality you would only be saving 3% and there would be less motivated buyers viewing their home, which typically results in lower offers and ultimately a lower sales price.
If you are committed to selling your home on your own, however, there are a lot of established feeds on Bigger Pockets that will give you the best practices for doing so. Professional photography is a MUST. Cleaning, decluttering, and staging will help tremendously. Most importantly you need to list at the right price. Don't list for what Zillow says your home is worth. You need to do a full comparative market analysis and find the true value of your home. You also need to account for the fact that we are in the Fall/Winter and there are less active buyers looking for a home. So doing absolutely everything you can to get in front of the most buyers is very important!
Hopefully this information helps and I do suggest at least interviewing with a couple real estate agents. Usually they will do a free home valuation and give you an idea of what you need to do to your home to be in the best position to sell.
