Thank you for your question.
When you sell it you will be exposed to capital gains tax.
Since it was gifted to you, then the cost basis is the adjusted cost basis of your father at time of the gift.
Capital gains tax is 15%.
If one of you is divorcing, your spouse may be entilted to half of the proceeds of the sale of the property. It depends on the court.
Normally a gift is considered seperate property, but circumstances of your marriage and hanlding of the property or other matters related to the divorce settlement may make one persons share of this property divisable.
For example: any increase in value of the property during a marriage would be considered marital assets, but the base not.
Quite possibly you are.
The capital gains formula is:
Capital gains (gift) = 258,000 - (Adjusted cost basis at time of gift, + improvements, + major repairs) - cost of selling.
Where Major repairs are those that you make that are intended to last one year or more such as carpets, flooring, roofs, etc.
