Final answer:
The gross estate value presumed in the question is $1,350,000, however, without full context or additional property details, this figure cannot be confirmed. Estate valuation depends on the total value of assets owned at death, and professional estate valuation would be necessary for accuracy.
Step-by-step explanation:
The question pertains to the calculation of the gross estate for estate tax purposes following the death of an individual named Jeff. We are given fragmented property values without clear context, so an assumption is made that the value of property inherited from Jeff's wife is $1,350,000, as mentioned in the question prompt. However, based on the provided reference information, the two property valuations detailed are for Freda's house at $250,000 and Frank's house at a net equity value of $100,000 (value of the house $160,000 minus debt owed $60,000). For estate tax calculations, as per the LibreTexts reference, personal property values also need to be considered, as demonstrated by the valuation changes for Joel Lax's property from the Federal Census data.
Considering the information from LibreTexts, if Jeff's estate value were below the threshold (which was $5.25 million in 2013), it would be exempt from federal estate tax. However, the provided fragments do not supply adequate information to determine the total value, so the value of property included in Jeff's gross estate is assumed to be the singular value of $1,350,000, as no further information was provided to clarify or confirm other property values. Professional advice would normally be sought to ensure the correct valuation.
