The mortgage balance is meaningless, for tax purposes.
The cost basis in a gift is the giver's basis. Your cost basis in the house will be what your mother paid for it*. So, when you sell the house, your taxable capital gain will be the difference between what you sell it for and your cost basis**.
*You would add any improvements, you mother made over the years, to the cost basis. If you father is deceased and previously owned the home with your mother, there is another cost basis adjustment that is made for when the titled transferred solely to her.
**The usual rule, for a gift, is that the recipient's basis is the giver's basis (what you mother paid for it). But there is an exception for the gift of her home, where she retained the right to live there ("life estate"). (seehttp://www.njelderlawestateplanning.com/2010/02/articles/estate-and-inheritance-tax/life-estates-estate-tax-and-inheritance-tax-consequences/ which states in part "If you give away an asset and keep a life estate in that asset..... the cost basis of the house is "stepped-up" to the value of the house on date of death [IRC 2036]")
The difference between the current value of the house and her cost basis is a gift of equity. If the total value of the gift (basis + equity) is more than $14,000, you mother (not you) will need to file a gift tax return (a separate filing from income tax). "Gift Tax" is somewhat of a misnomer. Even though a gift tax return may be required, very few people ever actually pay federal gift tax. The purpose of the gift tax return is usually only to document a reduction in the allowable estate tax exemption.

Ok thanks so I wouldn't need to pay taxes of difference of fair market and what I purchase it for
Are you buying it or is she giving it to you as a gift? Either way you report it when you sell it. If she is selling it to you she needs to report the sale or might have to file a gift tax return.
One word of caution--you did not say why your mom wants to gift the house to you. Just in case it is because she is getting older and suspects she may need Medicaid & nursing home care in the future, be aware that there is a five year lookback at any assets she disposes of.
And actually you should wait to inherit it. If it is a gift then your cost is what she paid for it and you don't get a step up in value.
Ok thanks she owes 60,000 and purchased originally for 125,000 and appraised for 300,000 so I would only pay taxes on originally purchase price?
If your mother gives you her house and then you sell it; you will have to report a long term capital gain (LTCG)* of $175,000 (300K - 125K = 175K). Depending on how much total income you have LTCG are partially taxed at 0%, 15%, 20% and/or 23.8%.
If your mother sells the home, herself, there is no tax. Taxpayers may exclude up to $250,000 of gain on the sale of their principal residence if certain rules are met.
*It's considered a long term gain, because your mother's holding period transfers to you with the gift.
