Definitions

The term “first-time homebuyer” means any individual if such individual (and if married, such individual’s spouse) had no present ownership interest in a principal residence during the 3-year period ending on the date of the purchase of the principal residence to which this section applies.

(A) In general The term “purchase” means any acquisition, but only if— (i) the property is not acquired from a person related to the person acquiring such property (or, if married, such individual’s spouse), and (ii) the basis of the property in the hands of the person acquiring such property is not determined— (I) in whole or in part by reference to the adjusted basis of such property in the hands of the person from whom acquired, or (II) under section 1014(a) (relating to property acquired from a decedent).

(B) Construction A residence which is constructed by the taxpayer shall be treated as purchased by the taxpayer on the date the taxpayer first occupies such residence.

The term “purchase price” means the adjusted basis of the principal residence on the date such residence is purchased.

A person shall be treated as related to another person if the relationship between such persons would result in the disallowance of losses under section 267 or 707(b) (but, in applying section 267(b) and (c) for purposes of this section, paragraph (4) of section 267(c) shall be treated as providing that the family of an individual shall include only his spouse, ancestors, and lineal descendants).

In the case of an individual (and, if married, such individual’s spouse) who has owned and used the same residence as such individual’s principal residence for any 5-consecutive-year period during the 8-year period ending on the date of the purchase of a subsequent principal residence, such individual shall be treated as a first-time homebuyer for purposes of this section with respect to the purchase of such subsequent residence.
