Since your Mother willed the house to you you could be subject to estate or capital gains tax. There is an exemption amount that can be willed and not be subject to tax. I think it is like $2M. You need to establish a basis price for the house (house value) when your Mother gave you the house. That way you might have that amount be covered under the exemption. Once you have that basis price you will only be responsible for tax on the capital gains above the basis price when you sell.
