@bigmasterdrago,
Real property is
real estate only. Not the car, jewelry, etc.
Any chattel (that's property that isn't real estate, e. g. the car, etc.) will likely have to be appraised if valuable. The will's executor (or executrix if female) will be required to divvy up the property as closely as possible to the intentions expressed in the will. This will likely mean selling a lot of the chattel if your mother dies and is utterly out of funds.
The executor will also have to pay any bills which survive your mother's death, and they will do so out of the funds within the estate.
For more information, please contact a lawyer versed in trusts and estates who is admitted into the bar where you live, and pay that person for advice.
