If you are selling a large Trona farm, tracks of land or multiple family property, using an agent will take a large chunk of your sale for a commission. With such a big ticket sale, it may be best to sell it privately so you can retain most of your capital. You will need to complete all your own real estate contracts; getting legal advice may be worth the additional costs. You, as a private Trona seller can market your Trona property, negotiate terms and enjoy the full sale price to do with as you wish, whether it’s re-investment or adding it to your egg nest.
