Consult an attorney or an accountant. You will have to pay an inheritance tax. This will vary depending on the state and the value of the property you have acquired.
Your inherited real estate must be evaluated at the date of his death in order to establish a new basis in the property. If it is titled in a trust, the estate will avoid estate taxes, but if directly inherited, then his estate will owe estate taxes on it.
The best thing you can do is consult a qualified tax accountant in your area. State and local laws can vary and you don't want to make sure all your bases are covered. A good accountant can do this.
Your father is passed then father's property is inherited to you, but you meat a advocate and discuss the matters and discuss the tax with tax consultant.
