Your question raises both tax and real property issues at the very least. I would think that a gift tax return in addition to all of the attendant real property transfer documentation would be required. The transfers should not be terribly complex or expensive, but in order to preserve the chain of title and stay clear of any estate and gift tax violations, you should consult an attorney competent to handle such issues.

The transfer to you would be considered a gift for tax purposes since you are not paying fair market value for the property. Depending on the value and the amount of remaining gift tax exclusion that your mother has, your mother may have to pay gift tax. At the least she will have to file a gift tax return. You may also have reassessment issues for property tax issues. There is also the issue of step up in basis. If you mother gifts the property to you, then you will receive a carry over basis in the property, or the same basis your mother has for tax purposes. However, if you were to inherit the property after this year, you would receive a stepped up basis to fair market value at the date of death. You should consult with a local tax attorney familiar with real estate transactions.
