The inheritance itself is not taxable. However, since you sold the property, what matters here is the fair market value (FMV) of the property on the day it was deeded to you. If you sold it for more than the FMV, meaning you made a gain, then the gain is taxable. If you sold it at a loss, then you don't even need to report the sale, as you can't deduct that loss anyway, since it's inherited property.
